2018 FORD F-150 Engine Problems

I own a 2018 Ford F-150, with the Cougar V-8 and a turbocharger. A few years ago, while on the expressway, I had to accelerate to clear a dangerous situation. A message came up on the instrument cluster saying that I was seriously low on oil. I pulled off on the shoulder and shut the engine off. I checked the oil level and it was almost empty. The truck only had about 10,000 miles on it at the time. I had checked the level prior to leaving and it was full. Luckily, I carry extra oil on long trips, a habit I got into back when I used to drive beaters. I had enough oil to fill the engine back up with oil and proceed on my way. I have not had any oil loss since then, although I rarely drive the truck, except to pick up lumber or other...

The contact owns a 2018 Ford F-150. The contact stated that while driving at various speeds, the transmission unexpectedly downshifted before slamming into gear. The vehicle returned to normal functionality, but the failure became a regular occurrence. The check engine warning light was illuminated. The contact stated that on a separate occasion, while driving at an undisclosed speed, there was an abnormal popping sound coming from the transmission. The vehicle was taken to the dealer, where it was diagnosed with transmission failure. The transmission was rebuilt; however, the failure persisted. Most recently, while driving 55 MPH, the check engine warning light illuminated. The contact stated that the transmission downshifted unexpectedly. The vehicle was taken to the dealer; however, no cause for the failure was found. The manufacturer was not contacted. The failure mileage was unknown.

The contact owns a 2018 Ford F-150. The contact stated that when the vehicle was started in the morning and shifted into drive(D), the vehicle hesitated and then jolted into gear. The contact stated that the failure was intermittent but had become a recurring failure. The contact stated that the vehicle was also slipping out of gear. While driving 45 MPH, the transmission downshifted to 1st and the vehicle slowed down unexpectedly. There were no warning lights illuminated. Additionally, while driving at various speeds, the engine was making an abnormal clattering sound. The vehicle was taken to a local independent mechanic, who diagnosed the vehicle and determined that the transmission needed to be replaced, and stated that the cam phasers were possibly causing the engine to make an abnormal sound. The transmission was replaced; however, the engine failure was not diagnosed or repaired. The contact received notification of NHTSA Campaign...

The cam phasers have gotten so loud that it sounds like a diesel. Ford did some software "fix" that did nothing. I am concerned about trashing the motor if the timing jumps. These defective phasers are well know problems and extremely costly to repair. Ford has advised me to do the repair but they are quoting $5-6k for a fix of something they know was a defective design. My truck has 111k miles now but the rattle has been there almost from the start.

2018 3.5 Ecoboost with plastic oil pan. Ford acknowledges poor engineering and changed production to a single aluminum oil pan half way through 2018 production, but refused to fix the trucks already built. The RTV sealant leaks on the plastic oil pan causing reliabilities and protentional safety issues with the engine components if not caught in due time. Ford issued a TSB 20-2015 report out for fixing the issue. I have been to three ASA certified mechanic shops and all shops refuse to work on the truck. My only option is to go to a FORD dealership and they won't complete the permanent fix of putting in the full aluminum pan. The independent mechanics say they won't work on the truck due to liability issues. They said the truck always comes back to get fixed again. I have done two diagnostics testing with the ASA certified mechanics. They confirmed the...

Engine is ticking and whistling. Drive train issues cam phasers was told beginning of the problem

I was not in an accident. I have a 2018 ford f150 xlt and it has a 3.5 eco boost. My truck is leaking some type of oil from the top and has very bad fuel injectors which is why my truck cant accelerate and shakes extremely bad. When I sit at a red light my truck dies and I think i have a leaking exhaust. I bought a new battery but it still dies. I know they used to do a recall for a new engine from what i’ve searched but they don’t do it anymore and I don't think its safe for me driving while I have all those problems. I have not been in an accident but with all these problems my truck could possibly die or go out while i’m on the highway and just makes me nervous driving something like that when the 3.5 eco...

The vehicle experienced repeated failures involving multiple systems, including the transmission system (transmission replacement), powertrain/engine system (cylinder-related repairs), electronic control systems (vehicle computer/control module replaced multiple times), electrical system (ongoing electrical faults), and rear safety systems (backup camera failure). The vehicle is available for inspection upon request. These failures created ongoing safety concerns due to loss of vehicle reliability and malfunction of safety-related electrical systems, raising concern about unexpected mechanical or electrical failure during operation. The issues were confirmed and documented by Ford-authorized dealerships and independent service centers. Despite repeated repairs, the same or related problems continued to occur. The vehicle was inspected and repaired by Ford dealerships; however, one servicing dealership (Ford of Ventura) later closed, leaving unresolved issues without continuity of service. Warning lights and system alerts occurred prior to failures along with ongoing electrical malfunctions. Exact dates of first warning indicators are UNKNOWN, but symptoms recurred over...

The contact owns a 2018 Ford F-150. The contact stated that while driving at 20 MPH, the engine seized. Several unknown warning lights were illuminated. The vehicle was towed to a local dealer, where it was diagnosed and determined that the engine had locked up and needed to be replaced. The vehicle was not repaired due to the cost. The contact related the failure to NHTSA Campaign Number: 17V672000 (Engine); however, the VIN was not included. The contact stated that previously, the vehicle was diagnosed by the same local dealer as needing a camshaft phaser replacement. The vehicle was repaired under the Ford Customer Satisfaction Program: 21N03; however, the failure reoccurred years later, and the vehicle was taken to a local independent mechanic, where the same repair was performed. The vehicle was repaired at the owner's expense. The contact stated that the vehicle was previously taken to the same independent...

The long block has failed This has caused the vehicle not to allow for accelleration and have significant power loss. Yes this has been confirmed by the dealer. It has not been inspected by the manufacturer at this time. Two days before I took my trunk into the dealer for service, the service engine light came on. I parked my truck and did not drive it til I called the dealership. They told me to drive the truck slowly to their service department. I drove my truck to them after confirming it was ok. They are 6 miles from my home

I was driving along and the truck shifted out of gear. Throttled to high rpm’s and went back into gear causing me to temporarily loose control and it repeated itself 2 more times before I got it stopped and towed home.

2018 F150 2.7L @ 118,000 miles - Intermittent check engine light kept popping up about 1 month prior to this event, which was addressed at a mechanic, repair and replacement of spark plugs attempted, but not solved. DTC codes indicated a misfire on Cylinder 6. One day I was driving at highway speed when vehicle began to shake uncontrollably with check engine light flashing and audible alarm. Vehicle was put into "reduced power" or "limp" mode and side streets had to be taken in order to get home. After evaluation by 4 mechanics, all reported the cylinder had lost compression and that one of the intake valves on the cylinder were likely the problem. Ultimately, a Ford dealership was the one who performed the engine replacement and also agreed it was likely an intake valve. I am reporting this after seeing numerous intake valve recalls for Ford engines of similar...

I have a 2018 Ford F-150 with a 3.5L Ecoboost engine. In October 2021, I received a Customer Satisfaction Program 21B10, 21N03, and 21N08 notice of a software upgrade to reduce the engine cam phasor rattle on engine start up. This was a limited time repair notice. Unfortunately, I thought it was a recall notice and did not act on this upgrade until a few weeks after it had expired on July 31, 2022. When I called the local dealer a few weeks after this date, they stated they would not perform the upgrade free and instead would charge me. I also had a mechanic state that this issue was not required and recommended I not pay for this upgrade. Even if I had performed the upgrade, it doesn't sound like it would have necessarily fixed the cam phasor issue because thousands on Ford customers have complained. Over the years,...

-Auto stop/start system failed and is available for inspection. I was driving down the road and braked for a vehicle about to pull in front of me, when I let off the brake and pushed the gas I noticed the vehicle had shut off there was an error message on the information center, Error message: "Auto startstop shift to P, then restart engine" -I could've been in an accident due to immobilized vehicle -Vehicle taken to dealer. Was told the failure was unlikely to be duplicated. Was told to unplug(deactivate) auto stop/start system to hopefully avoid recurrence. -No -No messages or symptoms prior to failure.

Transmission has lots of issue, clunky shifting, surges, weird noises. Happens every time you drive. Dealer said it was normal but it's not. I've driven plenty of these 10r80s and they didn't have this issue. Engine makes noises that are not on other examples of this engine, my dad has the same truck and had similar issues and had to spend thousands of dollars to fix an engineering defect in the cam phasers. Dealer also said these noises were normal while under warranty - I see countless posts on forums saying the same thing then for others, after warranty suddenly its a problem because a retail job pays 30-40% more than a warranty job. Such a scam and you just keep allowing it. There is simply no reason that the 10r80 transmission and 3.5 ecoboost gen 2 engines haven't been recalled yet. Ford has issued updated parts, admitted to engineering...

When cold starting the engine, a rattling sound occurs caused by the cam phasers not aligning properly. My research shows that Ford claims this is not an issue, and has never issued a recall for this, however, I am worried that continued use might damage the engine further.

V6 eco boost 10 speed transmission is failing with 135,000 miles. Need to be replaced.

After Ford performed a PCM (Powertrain Control Module) reprogramming recall on 16 July 2025, the vehicle began experiencing repeated engine misfires, loss of power, and engine warning lights. The condition progressively worsened, leading to a leaking fuel injector, an EGR valve that stuck open, and eventual internal engine damage requiring full engine replacement. These failures involve PCM-controlled systems (ignition timing, fuel injection, and exhaust gas recirculation) and occurred shortly after the recall calibration. The issue has been confirmed and documented by an authorized Ford dealer. The truck has become unsafe to drive due to stalling and shuddering at highway speeds, which could pose a risk of loss of vehicle control. Warning lamps and a wrench icon appeared intermittently before the engine shuttering and loss of power. The vehicle and all repair documentation are available for inspection upon request.

rattle or knocking sound from the engine, particularly on startup with only 30,000 miles on it started happening around 20,000 miles now I have my truck jerking when I hit the gas before it is apparently saying this is not on recall even though it should be because this is not my fault and clearly these parts are really bad or they did not have it tuned correctly somehow

A defect in the 2018-2020 Ford F-150's 5.0-liter V8 "Coyote" engine that causes excessive oil consumption, potentially leading to engine failure, reduced efficiency, and increased emissions. Ford concealed this defect not letting owners know and didn’t issue a recall. The oil dip always reads as if there is not enough oil in the truck causing you to have to constantly top off oil which is always over the usual amount of oil needed. The excessive oil consumption and potential carbon deposits can lead to severe engine issues, including stalling or even complete engine failure. This has caused other issues. This oil consumption defect has been there since I purchased this vehicle causing oil changes sooner than needed. A manufacturing defects in the 2018-2020 Ford 10R80 10-speed automatic transmission, commonly found in newer F-150 trucks, causing issues like harsh/erratic shifting, jerking, and power loss. The erratic shifting and power loss can...

there is a know design defect in the cam phaser on the 3.5L EB motors. Ford knows this exists. They have since redesigned the Phasor system to correct this defect. This isn't wear, or use related. It is completely a byproduct of a defective design. The issue is that the repair costs over $7,000, none of which Ford will cover. IT is a known design problem. It is not due to wear, or accident, it is simply an engineering problem. Ford should be required to at least partially compensate owners for this known problem. My motor has less than 50,000 miles on it, and I just spent $7400 getting it repaired. That's about half the cost of a crate motor. It is simply not right for ford to sell a motor with defective compmonents, and expect the owners to pay for their design problems.

My cam phasers are failing for the third time. I purchased this vehicle used last year at 89,000 miles and now I have 101,000 miles on it. Before I got to 100,000 miles I started hearing a rattle on start up and didn’t know what it was. After researching it by the time, I figured it out I had over 100,000 miles And Ford says they will not do anything about it, although it is a known issue and they had a customer satisfaction program to address it. They should’ve had a recall because it is a severe product defect that if left unaddressed will ruin your engine. It appears from Ford’s records that my vehicle had its cam phasers replaced twice in 2021. And they did a redesign of the part, but they didn’t put the redesign part on my vehicle and it is now failing again. The repair...

Auto start stop. This has happened on several occasions where I will be traveling at highway speeds and my 2018 F-150 10 speed 10R80 Transmisson with a 5.0-liter motor has died while traveling. I have talked to Ford Engineering reps, and they say they have never heard of this. I have done research into the subject and there have been hundreds of reports of the same issue. I have an appointment scheduled for Ford to look into the issue.

Ford issued a service bulletin for a computer adjustment for a known cam phaser issue on the 3.5 eco boost engine while under warranty. This didn’t fix the problem. Now the cam phasers need to be replaced at a cost of thousands of dollars and Ford refuses to do anything to assist even though this was initially reported and taken to the dealer while under warranty. The internet is full of people with this same issue. The vehicle is at the dealer for repairs and they have confirmed this is the problem. Without the repair the engine will fail.

Despite following Ford’s instructions step-by-step and investing hours into multiple calls with the Customer Service Division, we were given the runaround and ultimately denied assistance, even though: •This is a known defect with the Cam Phaser, CSP issued for our vehicle. •We attempted to have the repair performed within the CSP period but were delayed due to pandemic-related part shortages and poor dealership follow-up. •Our warranty expired less than 30 days before diagnosis. Our documented timeline: •July 25, 2022 – Brought truck to Courtesy Ford for PCM reprogram under 21N03; told parts were backordered due to pandemic. After a week, we had to reclaim the truck for work needs. Service was poor, with no follow-up. •November 2022 – Returned truck; again no resolution or follow-up. •January 1, 2023 – Ford extended CSP under 21B10; still no symptoms at this time. •May 28, 2025 – Private shop diagnosed Cam Phaser failure;...

The contact owns a 2018 Ford F-150. The contact stated that while driving at various speeds, the vehicle hesitated to accelerate as intended while the accelerator pedal was depressed. In addition, the vehicle jerked abnormally and unintendedly upshifted. The “Service Transmission” warning light was illuminated. The vehicle was taken to a local dealer, where it was diagnosed with an internal transmission failure and a fractured valve cover. The vehicle was not repaired. The manufacturer was made aware of the failure. The failure mileage was approximately 84,700.

Cam phasers failed as they have with other 2018 f-150s with the twin turbo v6. Had dealer repair but was told truck vin wasn’t included in recall. Paid for myself. Contacted ford and was told they would not refund me due to my vin not being in the recall

The contact's son owns a 2018 Ford F-150. The contact stated that her son was adding engine oil to the engine between every scheduled oil change. The contact stated that on the last scheduled oil change, the technician stated that the engine had consumed 3 quarts of engine oil. The vehicle was taken to a dealer, and the dealer diagnosed the vehicle and determined that the engine needed to be replaced. The vehicle was not repaired. The contact stated that the manufacturer was contacted and was referred to the NHTSA Hotline to report the failure. The failure mileage was approximately 97,000.

The Cam Phase Shifters and timing chain have failed with only 83k miles resulting in a $7,500 repair. This is unacceptable. I would completely understand if it had 250k miles but this is a baby as far as mileage. Looking at f-150 forums this appears to be a common problem and ford has actually changed the design of the cam phase shifters so they know they are defective. Request you loook into this issue please.

The contact owns a 2018 Ford F-150. The contact stated that while driving at an undisclosed speed, there was an abnormal grinding sound coming from the vehicle, with the check engine warning light illuminated. The contact stated that the check engine warning light illuminated and then went off. The vehicle was taken to the dealer, where it was diagnosed with solenoid valve failure. The contact was informed that the solenoid valve needed to be replaced. The vehicle was repaired. The contact was informed that the oil needed to be changed at 3,000 miles instead of 5,000 miles. The contact stated that in 2024, the camshaft, seals, gaskets, and four VCT solenoids were replaced. In addition, an oil consumption test was performed; however, the failure reoccurred. The vehicle was taken back to the dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be...

I own a 2018 Ford F-150 with the 3.5L EcoBoost. It started having idling issues that eventually required the cam phasers to be replaced. While that was frustrating and costly enough, the bigger issue came with the 10R80 transmission. Despite performing all services on schedule and maintaining the truck properly, the transmission failed. After doing research, I found that this isn’t an isolated incident. On Ford forums and owner groups, it’s clear that the 10R80 transmission has been a widespread, ongoing issue for years. Thousands of Ford owners have been forced to spend thousands of dollars to repair or replace these transmissions—something that Ford should have addressed long ago with a proper fix or recall. It’s disappointing that a company with Ford’s reputation hasn’t taken accountability for a known defect that affects so many loyal customers. Something should be done to make this right for owners who trusted Ford to...

The contact owns a 2018 Ford F-150. The contact stated that while attempting to start the vehicle, there was an abnormal rattling sound coming from the engine. Neither a dealer nor an independent mechanic was contacted. The vehicle was not taken to a dealer or independent mechanic to be diagnosed. The vehicle was not repaired.

The check engine warning light was illuminated. Additionally, the contact stated that while driving at various speeds, the vehicle hesitated and downshifted unintendedly while the RPM increased, and the vehicle failed to exceed 50 MPH. The vehicle was taken to the dealer, where it was diagnosed, and determined that the cam phasers and the timing chain needed to be replaced. The vehicle was not repaired due to the cost. The manufacturer was notified of the failure and informed the contact that the repair could not be covered because the VIN was not included in Ford Campaign Number: 21N03. The failure mileage was approximately 67,751.

The contact owns a 2018 Ford F-150. The contact stated that while attempting to start the vehicle, there was an abnormal sound coming from the vehicle.

The contact owns a 2018 Ford F-150. The contact stated whenever the vehicle was cold started, the vehicle was shaking and shuddering abnormally. The contact stated that after 10-seconds, the vehicle started to idle smoothly. There was no warning illuminated. The contact had taken the vehicle to a local dealer, where it was diagnosed and determined that the cam phasers needed to be replaced. The dealer informed the contact that there was a manufacturer recall but the vehicle was no longer covered under warranty. The vehicle was not repaired. The manufacturer was informed of the failure and referred the contact to the NHTSA Hotline. The failure mileage was approximately 64,000.

Vehicle has had regular maintenance. It started rattling at startup and we took in for service. The service department said the 5.0L Ford Motors are pulling more oil than the manufacturer recommends and is causing engine damage up to and including engine failure. Thankfully we took it in as soon as it started making a noise, but that did not save the engine. Now we are facing a $16K repair for an apparent "known" issue about this Ford motor. Ford will not help and said to take it up with NHTSA to try to get a recall for this issue. This seems like a manufacturer defect, but they are not taking any responsibility for this problem.

Cam phaser failure. Has been a customer satisfaction program through Ford which I participated in but was not deemed to have the issue as described. The dealer has now inspected and confirmed it is the cam phaser and the program has expired.

While driving to Sam’s Club (approximately 20 miles from home), my 2018 Ford F-150 3.5L EcoBoost began running very rough, and the check engine light came on. I had the vehicle scanned, and diagnostics confirmed that the cam phasers are failing — the exact issue I had replaced under warranty at approximately 59,000 miles. The vehicle now has just 88,000 miles, and this failure occurred in under 30,000 miles since the original repair. I have maintained this truck with extreme care. I only use Motorcraft parts and fluids, change the oil every 3,000 miles or sooner, and always use premium fuel. This is not a maintenance issue. This is a design or part failure that Ford has not properly resolved. When the phasers were replaced the first time, I was told there was no warranty on the replacement parts. That is unacceptable. A known failure being replaced with an equally...

Complete engine assembly (including internal bearings), twin turbochargers, and water pump. - Failure Mode: While driving at highway speeds, the engine warning lamp illuminated “Low Engine Oil Level,” followed by an audible ticking noise from the front of the truck. Upon shutting the engine off and attempting restart, the engine locked up and would not turn over. - Availability: The failed engine and associated components remain intact on the vehicle and are available for inspection at my local Ford dealership or by any third-party expert. For safety, loss of power steering and braking assist occurred instantly when the engine warning lamp came on, greatly increasing the risk of a high-speed collision. - The engine seized without warning, stranding me on a busy interstate shoulder and creating a serious hazard to passing motorists and my personal safety. - On June 3rd, Ford‐authorized service technicians at Bird Kultgen Ford in Waco Texas,...

The vehicle is consuming oil at a 1 quart per 1100 mile rate. i have had it tested at a Ford dealer. there is Technical Service Bulletin (TSB) 19-2365 for the year, make and model but Ford isnt offering a repair. The repair is approximately $14,000.00 that should not be the consumers responsibility. Please help get a recall issued.

The contact was advised to contact the NHTSA Hotline to report the failure. The failure mileage was approximately 180,000.

In November of 2024, my truck was shaking, accelerating erratically, and felt like the transmission was slipping. The check engine light came on as well. I took it to the shop and after diagnosing that it was a misfire issue in cylinder 6, they replaced spark plugs, fuel injectors, and tried to switch out new coils. They found gasoline inside cylinder 6, and upon doing a compression test, it was well below 100%. The truck continued to have misfires in cylinder 6, ultimately leading to 0% compression in that cylinder after taking it back to the same authorship to diagnose. After researching online forums and technical bulletins, it’s clear this issue is not uncommon among 2.7L EcoBoost engines from this model year, suggesting a manufacturer defect. The cost to replace the engine (as now recommended) has been estimated at nearly $10,000. With the history of regular oil and maintenance by...

2018 Ford F150 XLT twin turbo 4wd. Since the day I bought it. Nothing but problems with lurching jerking at stops. Clunking when truck is on AND OFF. We have video of it. Pushing gas pedal and truck hesitates before it jumps forward always the transmission been to every ford dealer in our area they refuse to help or say they DONT HEAR the knocking or feel lurching all lies we have had at least 3 close calls avoiding accidents and 2 days ago the truck would not stop the transmission skipped and I hit a deer. My bull bar absorbed most of the impact. The 10 speed transmission is the issue and no one wants to hear it but ford wants $10,000 for a new transmission after I paid $48000 for this truck and it’s been in the shop half the time.

Ford had two recalls on 2018 F-150. My vehicle had both issues and was not part of the recall. They had a cam phaser recall that caused timing chain failure if not addressed and excessive oil consumption recall. My vehicle was regular serviced at Ford and it had a rattling noise which indicated possibly timing chain issue but Ford never mentioned any issues at time of service or any warning lights. The timing chain failed and caused damage tonthe engine. The engine has to be rebuilt or replaced for 10k-12k in cost.

The contact owns a 2018 Ford F-150. The contact stated while driving 75 MPH, the transmission unexpectedly downshifted into first gear. The contact stated that the gears were jumping. The contact stated that the vehicle decelerated to 45 MPH. The check engine warning light was illuminated. The contact stated that the wrench symbol was displayed. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was contacted and referred the contact to the NHTSA Hotline. The failure mileage was approximately 139,600.

Even with the update to add more oil pressure the camshaft phasers still failed. Happened up in the mountains on vacation. Very large rattle and jerking when first starting the engine. 71,000 miles. All maintenance has been done on time. No warning signs or build up. Ticking time bomb if continued to be driven

I purchase a 2018 Ford F150 on [XXX]. One week later I am experiencing truck not wanting to shift out of first gear. The shifting is hard and jerking. It jerk so hard that if my son and I didn’t have our seat belt on we would have hit the dash. It periodically will shift from the 9 gear to 1 then back to 4th & 5th gear. It’s I almost got slammed by the car behind me. It is scary I took it to a shop and a total transmission replacement needs to be done I reach out the dealership that told me before I purchased it, all used vehicles go through a thorough inspection. I trusted the dealership and purchased the truck. Under further investigation I contacted where the truck was serviced last and they did an oil consumption test because it is burning a lot of oil....

At 65k miles I have started to experience the dreaded 3.5l cam phaser rattle that Ford initially had a Customer Satisfaction Program on. Ford only repaired vehicles that were making a noise at the time of the program so they wouldn’t change my phasers even though they knew they had issues. I just got off the phone with ford customer support and even though I’m within the milage of the initial free replacement they won’t offer any assistance on the $8k repair.

The contact owns a 2018 Ford F-150. The contact stated while driving at an undisclosed speed, the accelerator pedal was depressed; however, the vehicle failed to accelerate as intended. The contact noticed an abnormal rattling sound and the engine ran abnormally rough. No warning light was illuminated. The vehicle was taken to the dealer where it was diagnosed with a failed cam phaser. The contact was informed that the cam phaser needed to be replaced. The vehicle was not repaired.

The contact was advised to contact the NHTSA Hotline to report the failure. The current...

At a little over 56,500 files, the engine started having a load rattling noise during a cold start where the engine has been sitting for a few hours. I dig some Google searches and found that the noise was related to the cam phaser issue associated with Ford's 3.5L Ecoboost engines so I took it to Jim Vreeland Ford in Buellton, CA to get an official diagnosis on July 1, 2025 that costed me $196. The dealer confirmed that the noise is caused by the cam phaser issued that was noted in Ford Customer Satisfaction Program 21N03, which I never received a notification for. Ford apparently issued TSB 23-2143 to address the issue, and I was quoted $3158.07 to address the issue along with $2026.71 for unrelated but recommended components that should be replaced at the same time. I was told that this can lead to catastrophic engine failure if...
