2023 CHEVROLET SILVERADO 1500 Engine Problems

My 2023 Chevrolet Silverado 1500 has experienced two separate major drivetrain failures — complete transmission and turbo replacements — within two years of purchase, both during peak use months. The second repair kept the vehicle in service for nine months with no ETA provided until escalation. The repeated failures have rendered the vehicle frequently unusable, caused significant business loss, and represent more than normal wear. Documentation of repairs and dates is attached.

My 2023 Silverado 1500 6.2L ZR2 AEV with 17,500 miles went into the shop for the L87 Loss of Propulsion recall, on 20 OCT 2025. The dealership didnt contact me for 2 weeks, so I called. They than told me my truck failed the pico test and needed a new engine. I also asked for my leaf springs to be looked at under tsb for excessive noise. I also asked for my ZR2 to have the new update installed for the radio fix (my speakers crackle when I talk to people on bluetooth). They had my truck from 20 OCT 2026 until 27 JAN 2026 for a total of 99 days straight. No loaner was available. I had to call GM customer service every week for subpar updates from the dealership. Im active duty army so not having my pov to report to work was very stressful. When I got...

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving at undisclosed speeds, the vehicle lost power, jolted, and then stalled. The vehicle rolled while on a hill. The check engine warning light was illuminated. Additionally, while accelerating from a stop, the vehicle stalled again. The vehicle was taken to an independent mechanic and a transmission-related error code was reset; however, the warning light reappeared. The vehicle was taken to the local dealer, where it was diagnosed and determined that the transmission needed to be replaced. The vehicle was repaired. The manufacturer was contacted and assisted with the cost of the repair. The failure mileage was approximately 35,000.

I am writing to formally document a series of catastrophic mechanical failures involving my vehicle, as well as serious inaccuracies currently reflected on the Carfax report. At approximately 15,000 miles, my vehicle experienced a catastrophic engine failure that required a full engine replacement. Less than 900 miles after the engine replacement, the vehicle then suffered a catastrophic transmission failure, which also required replacement. In connection with the transmission failure, there was also a fuel module issue that left me stranded. These failures were not minor or routine service events. One breakdown occurred on a major roadway and required the road to be shut down due to the vehicle being disabled. Another breakdown occurred on the Florida Turnpike as a result of complete engine failure, leaving me stranded in a highly dangerous situation. Despite the severity of these events, the Carfax report does not accurately reflect what occurred. The Carfax report...

CONCERN OVER 6.2 ENGINE FAILING WHILE IN CONGESTED TRAFIC

My husband was driving on Plank rd/rt 219 towards Ebensburg PA when the truck started to buck and he turned off the main road and it shut down. It would not start just said low battery. I had it towed to the garage we use. They just confirmed it is the engine it locked up. I had the inspection for the recall and had the oil changed prior to this happening.

I was notified that my 2023 Silverado had an open recall (L87 Engine loss of propulsion). I brought the truck to the dealer for the recall on 8/19 with 35,921 miles on the vehicle. The inspection was performed and I was told it passed. When I asked about the extended special coverage they told me they didn't know what I was talking about. Only 4 months and 4,567 miles later, on 12/29, the vehicle shutdown in traffic and was not able to restart. The engine had failed and the starter fuse blew due to the motor being seized. The dealer relaced the engine due to the same recall that the engine had already been inspected and passed the inspection for.

My truck took my truck to Austin and back. Woke up the next day. Started it at approximately 4 o'clock in the afternoon and had engine oil low alert. Got out check the oil in my truck and there was none on the dipstick with the truck off of course. Checked at two other times allowing the dipstick to stay in for three or four minutes. Still no oil on the dipstick. Did not drive truck any further. Truck has the 6.2 L and I had the recall applied to the truck on December 8. The truck has 88% of the oil life remaining according to the truck.

My truck passed the recall PICO test right at 20,000 miles. The dealer put thicker 0w40 oil in. Less than 2,000 miles later, upon hard acceleration from 5-8mph, the engine climbed to 58mph then lost power, shifted itself into Neutral and coasted to the side of road. Truck was towed and told the engine seized up. Changing the oil did not make sense to me as lubrication was always available previously, thickening it does not change the port mill sizes for properly oiling the crank bearings. Now the new engine is revised but I see failures in low milage 2026 models happening.

The contact owns a 2023 Chevrolet Silverado 1500. While driving approximately 45 MPH, the message “Reduce Acceleration – Drive with Care” was displayed. The vehicle was driven to the residence with an abnormal rattling sound coming from the vehicle. The vehicle was taken to a local dealer, but the vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 80,000.

After have the engine tested it was determined that my vehicle will receive the 0W/40 oil. After that change I have notices a lot of rattling and the engine not behaving like it should.

On 1/21/26 traveling on a 4 lane divided highway, vehicle stalled, several warning lights came on and vehicle came to a complete stop in driving lane. Vehicle locked in park and could not put vehicle in neutral to push it out of highway. Several vehicle swerved to avoid and until tow truck came blocked a lane. It was about 3:30pm fortunately. So vehicle was visible and no accidents to our knowledge occurred. Thai created a dangerous traffic situation. It was caused by a fuel pump control module Whig was repaired 2 days later at local Chevy dealer. We were advised there were no recalls on this part but it is a common problem. GM should somehow find a solution and repair said problem

September 2025; the fuel control module failed at 75 mph in the left lane of I-45 requiring me to pull over on the shoulder in heavy traffic. I eas towed to my dealership 170 miles. At that time the recall test was performed on my 6.2 L L87 engine and passed inspection. The oil was upgraded at that time. Jan. 3, 2026 at 65 mph the engine died, once again on the highway at over 65 mph. Again I struggled to get to the right shoulder in heavy traffic. At the moment of failure, the engine revved from 1500 rpm to 3900 rpm and instantly fell to zero rpm and died. A message on the dash read unable to put in vehicle neutral. Again, I had it towed to my dealership where it's been diagnosed with a seized engine and I'm waiting (three weeks so far) on an engine replacement....

The motor blew with no notice, around 1000 miles after the recall inspection. My safety, along with the others around me was put at risk as I was in the fast lane during rush hour traffic with no motor to aid switching lanes to get to the shoulder. Finally died at one of the busiest intersections in the state, for the last time, as I was attempting to limp to the dealer via multiple restarts. leaving me stranded on the side of the road on a wonderful January day. The vehicle has been inspected by the dealer and slated for an engine replacement. No notice, I let off the gas, and when I went to accelerate again, the motor shut off.

Can shaft and lifters failed

General Motors sent me a letter regarding a safety recall regarding my 6.2L V8 gas engine (ROP L87). Safety recall N252494000. I learned that my truck has the potential to have a complete engine failure. I took my truck to the dealership and all they did was an inspection and changed the oil on it. I'm not a mechanic, but total engine failure is concerning to say the least. I doubt simple change in oil thickness remedies serious recall. I learned there is an open lawsuit regarding this issue. I need Chevy to take this matter more serious, Im driving my family around in a ticking time bomb. I demand more than a band-aid. I want Chevy to replace my engine with a new reliable one.

While driving at 70mph, my vehicle spontaneously shifted into Neutral and therefore dropped power to the transmission. I was unable to shift out of Neutral and therefore had to coast to the shoulder. Upon coming to a complete stop, my truck independently shifted into Park. Again, I was unable to shift out of Park. I turned my truck off, let it sit for a few seconds before unsuccessfully attempting to restart my vehicle. Multiple attempts to restart my vehicle continued to be unsuccessful and the vehicle system would reboot then shut off.

My vehicle was part of the recall N25494000 L87 Engine loss of propulsion. Vehicle went in for recall on Sep-30th 2025, PicoScope Inspection was done and vehicle passed. Oil was changed to 0W 40 with new oil filter. Dec-26/27 of 2025 vehicle started stalling, for no reason but no Engine light. The dealer said there was no problem because there was no engine light, so there was no way to find out what was wrong. January 11th 2026 vehicle lost propulsion 7 times on the freeway, vehicle had a hard time re-starting and started smelling oil burning smell. Vehicle Engine light stayed on, 1/11/2026 vehicle was running a little rough with abnormal tapping noise but made it to the dealer for inspection.

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 MPH, the vehicle lost motive power. The contact stated that several unknown warning lights were illuminated. The contact pulled over and turned off the vehicle. The contact restarted the vehicle after twenty minutes and was able to drive normally. The contact stated that after starting the vehicle and shifting to drive(D) or reverse(R), the vehicle failed to move. The contact stated that recently the vehicle stalled, and the check engine warning light was illuminated and was not turning off. The contact had taken the vehicle to a local dealer, but the vehicle was not diagnosed. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 19,000.

While driving at highway speeds, in traffic, all dash lights lit up and the engine shut off. The truck began decelerating on its own, I couldn’t brake and could barely steer. Luckily I was going fast enough that I managed to coast about a hundred feet to get partly out of traffic. The truck would never start again and I had to wait for 7 hours for GM roadside assistance to tow me to a Chevy dealer that was 4.6 miles away. 23 hours later the dealer called me and told me the starter caused the problem, in which I told them made no sense. 30 mins later they called and said the motor failed due to recall N252494003 for the L87 engine. My truck had passed the recall inspection for this recall on Sep 24th, 2025 and received the new oil that was supposed to prevent this failure. I...

I was driving my vehicle when the check engine light came on and a message then came across the screen and stated the truck would no longer shift if I didn’t stop driving it. I took It immediately to Autonation Chevrolet Service on Nov 9. I received it back on 11/26 my service advisor said it passed inspection that no work was completed I needed to use high synthetic oil and filters for my truck to keep it going. This doesn’t sound correct when I’ve owned several Chevy/GMC trucks. I only have 33k miles on my truck and want the recall fixed. Please help me get this taken care of.

While driving and idling, my 2023 Chevrolet Silverado 1500 High Country equipped with the 6.2L v8 engine began experiencing a persistent audible ticking/clicking noise from the engine bay, rough idle during cold starts, and noticeable/abnormal engine vibration. Shortly after, the check engine light came on. When scanned, diagnostic codes P0304 (Cylinder 4 Misfire Detected) and P050D (Cold start Rough Idle) were retrieved. The vehicle was inspected by an authorized Chevrolet dealership, and the service advisor and technician confirmed hearing a consistent clicking noise and documented that they contacted GM's Technical Assistance Center (TAC case #80413912). The service order report states: "Due to unknown noise cannot perform recall. Called TAC 80413912 and was told need to figure out top end noise and misfire before proceeding with recall. If repairs are related to top end, will not be covered under recall." The technician indicated this could be related to a camshaft and...

1.Coolant control valve failure 3 times within 125,00 miles causing the engine to run hot without overheating indication, losing heater and defrosting capabilities unable to operate safely with windshield freezing, 2. in addition this also caused the engine to run hot enough to burn manifold gasket and cracking manifold creating carbon monoxide to enter through cab vents. $4500 repair cost-that in order to operate safely. 3. Finally on star safety features not available due to module battery dead only after 2 years gps,emergency call and everything else included in this safety feature unavailable $1,000 cost manufacturer or dealer will not recognize any of these due to warranties and expiration.

I WAS DRIVING ON THE HIGHWAY DOING 75 AND THE TRUCK STARTED JURKING AND SLOWING DOWN BY ITSELF AND GETTING LOUD. THE DISPLAY STATED REDUCE SPEED AND THE CHECK ENGINE LIGHT CAME ON..

Driving down the road and the engine turns off with no warning lights, noise, or any indication of an issue. I was luckily able to use momentum and move to the side of the road. The Chevy dealer has inspected the engine and concluded that the engine is blown.

I am filing a complaint regarding a potential recurring safety defect related to Recall NHTSA 25V274 (GM N252494001). On July 29, 2025, my vehicle stalled while driving on the highway and was towed to Quality Chevrolet. The dealer diagnosed a failed starter and battery fuse link. During this visit, I authorized inspection for Recall 25V274, concerning possible crankshaft or connecting rod failure. I was told my vehicle was not affected but the dealer performed the recall remedy by changing the oil to 0W-40. On October 5, 2025, the vehicle developed a loud knocking noise from the engine. Quality Chevrolet diagnosed a connecting rod failure, the same issue identified in the recall. On October 10, 2025, I was advised that GM approved a full engine replacement due to internal damage. However, I was also told the new engine will use lower viscosity 0W-20 oil, contradicting the prior remedy intended to prevent...

The 2023 Chevrolet Silverado 1500 High Country has experienced multiple powertrain and transmission failures beginning shortly after purchase. The issues include violent shifting, hesitation, and stalling, particularly while accelerating or decelerating. These malfunctions create serious safety risks—especially when merging, turning left across traffic, or entering intersections. The truck has been returned to authorized GM dealerships multiple times for diagnostics and repair. GM service departments confirmed transmission faults but have not successfully resolved the issue despite repeated attempts. The same problems reoccur shortly after each repair. At times, the vehicle has entered “limp mode” unexpectedly while driving, causing a loss of power. On at least one occasion, this occurred while driving on a busy highway, forcing evasive action to avoid a collision. Warning lights such as the “check engine” light and service alerts frequently appear before or during these incidents. To date, the vehicle has been inspected by GM-certified technicians at...

We bought 2 of the same exact trucks last year. They each had no miles on them. My business partner was coming home from vacation and stated hearing ticking. We took it to our mechanic and he said it’s a blown motor. Prior to leaving for vacation, an oil change was done on the truck. When the mechanic said the motor is blown he also said it’s down 3 quarts of oil. All scheduled maintenance was done on the truck routinely. We took the truck back to the shop that did the oil change and they had recorded the service, there was no doubt the oil was changed the prior week but it was now black and down three quarts.

I have a 2023 Chevy Silverado 1500 3.0L Duramax Trail Boss. Temperature gauge keeps flocculating, engine fan kicks on at 100% and shuts off the AC. Warning on dash engine temperature to high AC shutting off and engine over heat. Took it to the dealership for the truck is still under warranty. They diagnosed it as a faulty coolant control valve. Was told it was safe to drive by the technician but I question that. Dealership ordered the part four weeks ago and it still has not come in. When I inquired about the delay, I found out it is on back order and the availability of the part long wait time. Further research found that this is a systemic issue owners are having with this specific engine since 2020. Yet GM has not done a recall nor is there supply stockage of this part, seeing how this part commonly...

The vehicle shots forward after some delayed acceleration.

1. GM affiliate Roger Dean Chevy in Cape Coral Florida is refusing to Inspect/Repair/Replace defected engine as per the Safety Recall May 2025 letter. 2. Engine has Not failed yet per the Safety Recall May 2025 3. The recall has been recognized by the Chevy Dealership as an issue and has refused to remedy the safety issue. 4. Dealership has refused to inspect or remedy the issue per the Safety Recall May 2025 letter 5. The engine failure has Not happened yet but as the owner I fear for mine and my family safety and want this Fixed/Replaced entirely.

The vehicle began making a loud fan noise in the engine after the summer began (06/2025) and the temperature gauge was elevated but not by a concerning amount. After an oil change (06/21/25) we were told that it was normal because of the weather. A week after the check engine light was coming on intermediately (began 06/28/2025) depending on the day and the temperature outside (we are currently in the middle of a heat wave). The vehicle was taken to the dealership (07/02/2025) where they determined that the coolant flow was too low and found that the engine coolant pump is faulty and needs to be replaced. f the coolant is low in a Chevy Silverado and the engine overheats, it can lead to significant and potentially expensive engine such as a blown head gasket, cracked engine block, or even a complete engine failure or fire.

I been to the Chevy dealership a few times for the 6.2 L recall that I have and I keep getting turned away

So I experienced a P1098 code in my 2023 Chevy Silverado with a 3.0 liter Duramax. When you get this code the truck will go into “limp” mode with reduce (nonexistent) acceleration and only go to about 60 miles per hour (63) I think. This could become a large safety issue if someone was to experience this going down the highway. It is also a VERY common problem doing internet searches. Seems that GM knows this is an issue but does nothing about it. In fact they even tried to remove the part from warranty because it was happening so often. Seems like this is something the government should look into and see what the true cause of the issue is. On the other hand some of the reliability of these engines is caused by the government implementing many restrictions on the manufacture to meet certain requirements. I am frustrated...

I own a 2023 Chevrolet Silverado 1500 ZR2 equipped with the 6.2L V8 L87 engine. My vehicle is included in Recall Number 25V274 / N252494000, which addresses manufacturing defects in the connecting rods and/or crankshaft that can cause engine failure. My recall status currently shows: "Recall Incomplete, remedy not yet available." However, GM and NHTSA have already stated the remedy: a VIN-specific engine inspection, followed by either a replacement or an oil system update and extended warranty. I contacted my dealership, Lochmandy Chevrolet in Elkhart, Indiana [XXX] ), and was told on June 1, 2025, that they could not inspect my truck due to lack of tools or VIN clearance from GM. I was given no estimated timeline for when I can get my vehicle serviced. My concern is that I’m driving a known defective vehicle with a potential for sudden power loss or engine seizure—a serious safety hazard. My...

I take my truck in for regular service at my local Chevy dealership. When I found out about the recall on my engine back in April I immediately took my truck in. Was advised that they would address the issue. They did a regular maintenance and told me that they just used higher viscosity oil. I will be taking my truck in for the 3rd maintenance tomorrow 6/13/25. My vehicle status still shows that the recall needs to be addressed. I feel that I should park my truck due to the information provided on the recall of losing propulsion at any given time without notice. I also want to note that there is a noise coming from my engine that shouldn’t be there.

Accelerating getting onto the highway, at about 65 mph I heard and felt 2 clunks and I lost propulsion. I made it to the side of the road and the vehicle went completely dead. I tried restarting it and it wouldn’t do a thing.

This is the third time since the purchase date of July 2023, that my Diesel 1500 Silverado has gone into "Reduced Engine Power" while driving. The first date was August 2024, while traveling down the interstate. The check engine light came on. My maximum speed was reduced to 50mph, and the transmission shifting was very jerky. This was extremely dangerous with the flow of traffic traveling 70+ mph. I returned to the dealer where the vehicle sat on the lot for approximately 60 days awaiting the part (Valve Body) from GM. Components were repaired through warranty. Fast forward to February 2025, "Reduced Engine Power" notification came on again with the code P0747, P700. Returned to dealer, and after a week of sitting on the lot, the technician could not duplicate the code. I requested that a new fuel filter be replaced for piece of mind. Today, 3 mos. later, as...

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving approximately 30 MPH, the vehicle stalled. The contact stated that several unknown warning lights were illuminated. The vehicle was taken to the dealer, who diagnosed that the lifters had failed. Additionally, metal shavings were found inside the engine. The engine was replaced. The manufacturer was informed of the failure by the dealer. The failure mileage was approximately 61,000. The VIN was not available.

Connecting rod and/or crankshaft engine component failure, engine damaged, engine light came on as knocking sound started. I have had to replace the motor as vehicle was undriveable. Engine failure can lead to accidents.

In August 2024 my 6.2 Chevrolet Silverado motor blew up. I was driving uphill when all the sudden it made a very loud sound like I had floored it and I had not. The engine revved really, really really high red line then it flashed across my dash to turn off the motor and the vehicle just shut itself off.. It left me stranded in the middle of the road and had to be towed to a Chevrolet dealer. It took them approximately 3 weeks to diagnose it as a catastrophic engine failure. And several more weeks to replace the motor, radiator and coolant lines. There was engine pieces in the radiator. Chevrolet refused to reimburse me my full cost of the rental that I had to get until they approved me a loaner..

Code P1098 associated with reduced engine power, forced speed reduction and overheating while on the freeway, limiting power and capping speed @ 55 MPH. Causing dangerous issues on the highway putting drivers in a dangerous position

On 4-25-2025 while driving the car shutoff twice losing power on both occasions. The first time I was able to start the truck; however, the second time it happened I lost all power and drifted to a stop. Vehicle info said to put the car in neutral and press the start button. Car failed to start while drifting and when I was able to get the truck to a complete stop, the truck could never start thus requiring it to be towed to the dealership. Truck has a little over 22000 miles. Check engine light came on after the second incident.

I have had an intermittent, aggressive engine knock and rough idle since i bought the truck. I'm assuming it has to do with the collapsing lifter issue from the fuel management system. when I bring it to the dealership (paradise chevrolet ventura) , they tell me that they cannot replicate the issue and that if there is no check engine light on the dash, there is nothing they can do. I am concerned for my families safety and my truck becoming an issue after my warranty runs out. my chief complaint has been documented by the dealership multiple times and I have video of me replicating the issue.

At 383 miles the engine started a ticking noise. Around the same mileage the transmission would also start make hard down shifts, especially into 1st gear. At around 27000 miles transmission would also shutter at light loads and low speeds. Attempted to take it to dealer 2 different times, but they had no loaner cars and needed it for more than a day. At milage 28,251 I drove to the dealership an insisted that it needed to be fixed. They were able to provide loaner car at that time. Engine ticking noise was cylinder number 7 lifter stuck closed. Transmission was unable to be checked due to engine needing repair. The Dealer replace all 8 lifters on drivers side of engine. Upon the fix they test drove for the transmission problem and noticed noise coming from the water pump. Replaced the water pump and was told transmission needed a new...

The contact owns a 2023 Chevrolet Silverado 1500. The contact stated that while driving 45 MPH and depressing the accelerator pedal, the engine seized, and the vehicle lost all power. The contact stated that the vehicle was stuck in the right lane. The vehicle was towed to dealer, where it was diagnosed with engine failure. The contact was informed that the engine needed to be replaced or rebuilt. The contact stated that the timing chain was replaced on two separate occasions. The vehicle was not repaired. The manufacturer was notified of the failure and opened a case. The approximate failure mileage was 15,121.

On [XXX] around [XXX], I was driving my Silverado down [XXX] near the Cottonwood Mall in Albuquerque, NM. Without warning, the engine died in the center lane of this busy highway. I turned on the emergency flashers, then while trying to call for emergency help on my phone, I stood behind the truck, waving traffic to the side lanes in an effort to prevent being rear ended. After about 10 minutes, luckily, an emergency fire department truck spotted my distress and doubled back, parked behind me and engaged his emergency lights. A good Samaritan stopped an attempted to toe strap me to the shoulder of the road. However, the poor design of this truck didn't allow me to put the transmission in neutral unless the vehicle is running. So, after about an hour, the tow truck driver was able to drag the Silverado on the back of his flatbed. After...

While driving my 2023 Chevrolet Silverado ZR2 with the 6.2L engine (approx. 22,000 miles) on a busy interstate in another state, the vehicle suddenly lost power and shifted into neutral without warning. I was towing a 5,000-pound camper and had my wife and three children in the truck. We were traveling on a slight incline when the truck unexpectedly disengaged. There were no warning lights, no messages, and no sounds indicating engine failure—just a sudden loss of drive. All displays remained illuminated, but I had no power to the wheels. By the grace of God, I was able to maneuver to the median before the truck and camper came to a complete stop. It was a terrifying and dangerous situation that could have resulted in a major accident given the speed of traffic, the weight of the trailer, and the total lack of warning. The truck was towed to a...

While traveling in a funeral possession noticed an engine stall with a blast of smoke coming from rear exhaust.
