2022 GMC SIERRA 1500 Engine Problems

The vehicle is subject to Safety Recall N252494001 (NHTSA Campaign 25V-274) due to manufacturing defects in the engine crankshaft and connecting rod bearings. • Component/System Failed: The 6.2L V8 (L87) engine crankshaft and connecting rod assembly. The engine is available for inspection upon request. • Safety Risk: The defect can cause catastrophic engine damage and sudden loss of propulsion while driving, significantly increasing the risk of a crash. • Dealer/Manufacturer Confirmation: The problem was confirmed via the issuance of Safety Recall N252494001. A dealership inspection was performed previously as part of the recall. • Warning Signs/Symptoms: Common symptoms include engine knocking, check engine lights, and hesitation before sudden failure. The Issue with the Remedy: Federal law (49 U.S.C. § 30120) requires manufacturers to remedy safety defects "without charge". As a permanent safety remedy for this defect, GM has mandated a switch from 0W-20 to 0W-40 (dexosR) oil for the life...

While driving I get a reduced acceleration warning on my dash cluster, drastically reducing horse power. My check engine light came on. This has happened before. I checked the code and it was a P1098 code. After researching I found out it was the Engine coolant control valve. My fan is constantly running. This issue is ongoing. This seems to be a common occurrence with my vehicle year.

My GM Dealership completed the GM 6.2 Engine Inspection and recommended Oil Replacement as part of the 6.2 Engine Recall. Roughly 5,000 miles after this service, the engine failed. I attempted to accelerate from 45-65 miles per hour while getting on the highway, and the engine seized up. I was able to coast/steer the vehicle to the side of the road. The vehicle's starter could not crank the engine. I had the vehicle towed to the shop where the dealership confirmed the engine had seized. The dealership and GM replaced the engine under a warranty repair. I am making you aware of this situation, as the manufacturers suggested solution to the engine issue (The Change in Oil Type, Filter and Cap) did not prevent the engine from failing.

engine recall 6.2 L-87 , after Pico scoop Test, which my truck passed, its using 2 plus quarts of oil per 1000 miles, the dealer has it and is saying they can find nothing wrong per the gm tech that is telling them to check this and that. Ok, oil is going somewhere, I want the motor replaced , they want to continue the oil consumption test, my thing is wasting my time to continue driving and bring back to it back for a low oil reading, Its not gonna fix its self by driving it. I understand gm wants to figure out why, but it should not be at customers time , replace the motor all ready, something is wrong. the first 1000 miles after a oil change and they put die in the oil to check for leaks. When They check the oil level friday 02/06/26 the oil...

54k miles. Crankshaft failure. Truck shut off and put in neutral while driving with no codes on dash. Got a text saying to service engine and transmission immediately. On a side note, it is bullshit that you can't put the truck in neutral to get it off the road. The dealership is also doing a great job covering it and offering a loaner.

To start off my truck has been to the dealership multiple time for the camera. After third time in the shop they fixed that issue. Then the infotainment started acting up after about 4 times in the shop it was fixed. They gave me the prescribed fix for the engine recall in november. Engine passed the test. Then 3 weeks ago the engine siezed up from the crank and bearings on the interstate doing 70 pulling a trailer in traffic. Leaveing me and my dad in the middle of the interstate. I had to have it towed 2 hours to my house. After the prescribed engine fix. They replaced the motor in 3 days. Great right? No they did not test drive long enough. Or they would have felt the shudder that developed after the new engine went in. It is now about to go back to the shop. Because...

I purchased my vehicle in June 2025. In January of 2026 the vehicle would sometimes shut down at red lights, requiring me to restart. No engine codes would pop up. On Jan. 16th, 2026, I exited my vehicle and heard a “cow bell clunking” coming from the engine area. I scheduled a service, and I was informed that the issue was part of the GM recall for 6.2L engines. This concerned me, because my vehicle had already had the “remedy” for the recall (changing engine oil type) prior to me purchasing it Certified Pre-Owned, and the engine still failed. The dealer I brought the truck to did a full engine (and appropriate parts) replacement as part of the open recall.

after i had the car inspected per thier recall on potential engines issues, the car passed and was told no issues. 6 months later driving on highway with family during rush hour and suffered complete engine failure going 70 mph. Lucky not to have been hit from behind. scary to be on highway like that. It was freezing outside. Dont understand being told car is fine and then this happens.

On November 16, while driving on the highway, my GMC vehicle suddenly lost engine power without warning. I was forced to stop in traffic, creating a dangerous situation and putting my life at risk. The vehicle required towing and has remained at the dealership since that date. The dealership determined that the engine requires replacement. Repairs have been significantly delayed, including an incorrectly ordered replacement engine, and the vehicle remains out of service more than two months later. This defect caused a sudden loss of power while driving and presents a serious safety concern.After the incident, I contacted the dealership immediately. Diagnostic appointments were scheduled and then canceled by the dealership twice, which delayed inspection and repair. I was only able to leave the vehicle at the dealership on December 12 due to these delays.

My vehicle stop running as I approached a traffic signal and failed to restart, it happened at a heavy traffic intersection during morning commute,I had the vehicle towed to Dealership that same day (01-22-2026). Later that evening the dealership called to inform me that the motor was blown and had ordered a new one.the mileage is approximately 39,285.

My TAILGATE kept opening randomly and ENGINE WAS MAKING CLUNKING SOUND initially. Lost many tools on the highway once when it opened. Dealership told me my truck is not covered under a recall for both issues, even though other similar vehicles are. I refused to pay anything to have it fixed. They claimed my truck “wasn’t built in the factory that has recalls”. A month later the STARTER AND BATTERY burned up when I started up the truck, something locked up it sounded like. Eventually it started but didn’t sound right. A few days later the engine finally blew up. I paid out of pocket for everything for that trip. It’s currently back at the dealer being repaired with a new engine for the recall but GMC refuses to pay for the initial clunking/starter/battery and the tailgate issues. I’ve encored so many charges with tows and rentals from all these...

2022 GMC AT4 w/ 6.2L V8 was my retirement gift to myself at a cost of $70k. I have had 2(two) engine failures! Of course they failed in the middle of rush hour traffic when no one wants to be kind. Since the wheels will NOT rotate once the failure has occurred, I was stuck in middle of traffic for 2 hours awaiting a tow truck. Not even 3k miles after the 2nd engine failure I was told by the dealership that I now need a transmission replacement. As a loyal GM customer, GM has to do better.

Complete engine failure, at 57,000 miles, was driving approximately 75 mph on the I-15 in Utah outside of St. George, and the left lane, engine turned off, was able to pull safely in a shoulder in a canyon with my family, my wife, my kids [XXX] and [XXX] old. Vehicle was towed that evening at 7 PM to the dealership, where it was diagnosed with completed engine failure. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

I had a lifter fail which is a well known problem for these GM engines. The lifter caused the cam shaft to be damaged because of the lobes being shaved off. Now I’m being told that it will be over $10,000 fix a 3 year old truck.

Radiator is leaking where plastic meets metal. Leaking coolant at upper corner driver side. This is crazy for a 70k truck. It is a known problem. Dealer refused to submit a claim to GM. I am seeing people get theses replaced. It has been an issue since coolant control Valve was replaced.

There was engine failure whereby the pushrods were ticking extremely hard. After towing the vehicle to the repair shop, it was determined that a new engine would be needed. The cost for repair was $11,500.00 dollars. The original engine has approximately 75,000 miles.

My 2022 GMC Sierra Denali Limited (6.2L L87) had an engine recall performed by an authorized GMC dealer (Paul Masse Buick GMC) in November 2025. Prior to the recall service, the vehicle had no check-engine lights, no drivability issues, and no knock-related symptoms. Immediately after picking up the vehicle from the recall service, the check-engine light illuminated within seconds of leaving the dealership parking lot. I returned the vehicle immediately. The dealer diagnosed a failed knock sensor and replaced it at my expense. There were no prior warning signs or symptoms before the recall visit. General Motors declined responsibility, classifying the issue as an out-of-warranty repair and confirming only that the recall procedure was followed. GM did not evaluate whether dealer handling, component disturbance, or recall-related activity contributed to the immediate failure. I am submitting this complaint because the failure occurred directly after recall service, suggesting a possible recall-adjacent issue...

My truck went into "limp" mode and had very little power. It was towed to the dealership where they diagnosed the issue as a bad solenoid causing the engine misfires. The solenoid was replaced, but the issue was not fixed. Now the dealership is stating the engine has bent lifters and the repairs will not be covered under the ongoing massive engine recall. The vehicle had the pico test on 9/17 and it "passed", but less than 3k miles later and the engine failed. This is a clear safety issue and well known by NHTSA and GM. Now I'm negotiating with the dealership to cover repairs and my truck has been gone nearly a month.

The CAM Sensor Failed and the reluctor ring was chipped. They could not determine without spending hours taking a part the engine if it was a piece of metal from the current recall that chipped off and broke the reluctor ring. No problems until immediate failure and had to had the car towed to the shop to identify issue.

Purchased vehicle in July 2025. Started having the engine failure issues described in recall "L87 Engine Loss of Propulsion (Related field action: See Special Coverage N252494003)". GM says that the recall work was completed in May of 2025, however, the same exact issue as described in the recall exists. Engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. We believe the recall fix was not performed properly as vehicle has same issue. Dealership has not helped us and GM referred us to you.

The engine in my vehicle has failed twice while driving at highway speed. Both times, the engine suddenly stalled without warning, causing an immediate loss of propulsion, lighting, and steering assist. Each failure occurred at night, and I had to coast to the shoulder in the dark with limited control while other vehicles traveled at high speed. During the second incident, two children were in the vehicle. Both events created a serious risk of a collision or injury. The failure involves the primary propulsion system. After the first incident, the dealer replaced the engine and performed recall-related updates. Months later, the replacement engine failed in the same way. The dealer inspected the vehicle after each incident, confirmed the failures, and is replacing the engine again. The issue has therefore been reproduced and verified by the service center. There were no warning lights, messages, noises, or drivability symptoms before either failure....

The contact owns a 2022 GMC Sierra 1500. The contact stated that on several occasions while driving at speeds over 20 MPH, the vehicle began shaking and the transmission shifted prematurely and hard. The contact stated that the check engine, traction control, ABS, transmission, and other unknown warning lights were intermittently illuminated. The contact stated that on one occasion while driving at an undisclosed speed, the brake was depressed; however, the vehicle failed to slow down as intended. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was approximately 46,000.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while operating the vehicle, the check engine warning light illuminated. The vehicle was taken to the local O'Reilly's, who diagnosed that the cylinder #2 glow plug had failed and needed to be replaced. The vehicle was not yet repaired. The manufacturer and local dealer were notified of the failure and informed the contact that the VIN was not included in the Manufacturer's Special Coverage that was related to the failure. The contact stated that the special coverage service was for the previous model years with a 3.0-liter turbo diesel engine that had experienced the same failure. The failure mileage was 38,773.

My GMC dealer falsely reported that recall work was completed on my engine but it was proven by an independent service center that it was not done. Items that have been proven to have not happened were 1. Replace engine oil with higher viscosity oil, 2. Replace oil filter to match new oil, 3. New oil fill cap labeled with oil type, 4. New insert for owner's manual. The way I initially learned the work was not completed was by warnings on my dash about low oil pressure and low oil level in my engine this past weekend. The independent service center provided confirmation that the invoice from my GMC dealer was falsified and that the work they stated was completed was not done. As a result of the failure to complete the work, my engine ran on insufficient oil and, based on the dirtiness of the oil in my...

Took truck in for recall on sept. 19th, it passed and oil was changed per recall. On Nov 1, driving on IH 20. engine oil pressure went to 0 and engine stopped. The dash showed that oil pressure was low and to pull over vehicle. I was going 75 mph at time. Pulled to emergency lane and engine died. Had to tow to dealer. It was very unsafe due to speed and traffic on highway. At no other time was there any indication of engine problem.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving at 60 MPH hauling a trailer going downhill, the engine seized. The vehicle was difficult to control. The message to “Shift to Neutral and Restart" was displayed. There were no warning lights illuminated. The driver attempted to restart the vehicle. The contact stated that the running boards were stuck outwards. The contact received notification of NHTSA Campaign Number: 25V274000 (Engine and Engine Cooling). The vehicle was towed to the local dealer, where the engine was replaced after two months. The dealer informed the contact that the battery was completely drained. The manufacturer was contacted, but no assistance was provided. The failure mileage was approximately 67,500.

2022 GMC Sierra has a P1098 code. This code has to do with a faulty coolant control valve. This causes the engine fan to run constantly and displays on the screen "Reduced Acceleration, Drive with Caution". The truck does not have any power when this happens, which is 99% of the time. This makes using the truck very difficult in high traffic areas and pulling a loaded trailer. Apparently GM knows about this and is not getting the part to correct the problem to the dealerships in a timely manner. My truck was diagnosed with this problem over 2 weeks ago and still waiting on the part.

Constant engine issues. Cams, lifters, now needs new motor. Motor apparently unavailable.

My motor locked up a year ago. Before the recall. At 74k miles. GM stated they did not know why it happened. Although there was 6 of the same trucks in their lot under 20k miles with the same problem. I was forced to pay out of pocket. I notified my GM dealer that my engine was knocking at 15k miles and they did nothing. Now that I have a new engine I have brought it to the dealer 3 times because it is also knocking. They’ve told me they hear it but theirs no code so nothing wrong with it….. GM refused to help me in any way nor will they help me get a reimbursement for their manufacture defective engine that I payed for. I had to take a $10k loan out to get back on the road. Every day that passes I am paying more interest because...

My truck is under the national recall from GMC for the 6.2L engine problems. I even received the recall notice from GMC stating this. This truck has been in and out of the shop for engine problems things I took delivery of it in 2022. The latest was in April of 2025 and while it was in the repair service at the dealership, the national recall came out. During that time the dealership tried to tell me the problem was with my exhaust system so I was not covered under the recall. I knew they were not being truthful so I refused to take possession of the truck as I new it had all the symptoms that GMC was describing in my recall notice. My truck sat at the dealership for almost 5 months and last week they force me to take possession of my truck my taking back my...

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving at various speeds, the radio and other electrical systems failed to function as intended. The contact pulled over to the side of the road and turned off the vehicle. After several minutes, the contact restarted the vehicle and the radio and other electrical systems failed to engage. The contact was unsure if any warning lights were illuminated. The contact stated that on a separate occasion, while driving at various speeds, the check engine warning light illuminated. The vehicle was not taken to the dealer or an independent mechanic. The vehicle was not diagnosed or repaired. Upon further investigation, the contact became aware of a recall on the VIN. The contact parked the vehicle at the residence and no longer drove the vehicle. The contact asked the dealer to provide towing service to tow the vehicle and...

I was notified by GMC of recall N25249000 by letter in May 2025. Shortly after I scheduled an appointment with my GM dealer to get the recall repaired but the dealer told me that GM has not told them how to repair the issue. The GM dealer told me they would let me know when GM tells the dealer how to repair the issue, so I could bring the vehicle back to repair the recall. I just received another notice from GMC about the recall today (08/11/2025). It has been roughly 4 months of waiting to get this recall fixed on my vehicle.

I received a recall notice in May 2025 for L87 Engine. To date, remedy not available. Per the safety recall letter provided, I'm notifying you that the dealer has failed "within a reasonable amount of time" to remedy this situation.

The vehicle’s shift control module in the transmission is malfunctioning. The vehicle is shifting hard and having trouble finding the gears. The safety issue is that this is a known GMC transmission malfunction with the risk that the rear wheels can lock up when downshifting in the higher gears. Sudden rear wheels lock up proses a risk to cause an accident on the roadway potentially harming the driver and passengers in the defective vehicle as well as risking other drivers on the road. No warnings were given before the malfunction. The vehicle has been regularly serviced on time and taken care of. The malfunction began and within one week the vehicle progressed to shifting so hard I didn’t feel comfortable driving it especially with my child in tow.

My daughter and I drove to town to run some errands, we live twenty-three minutes away and take the freeway. Speed limit on that specific section of the freeway (I80) is 80mph. As I was taking the on-ramp to enter traffic, My GMC started shifted very hard and losing power. The vehicle was sputtering and making strange sounds. I was unable to exceed 60mph due to excessive vibrations/shaking the vehicle. Steering was starting to be difficult at the same time I noticed Oil Pressure Gauge slowly dropping on instrument panel below 25psi. I had to pull over immediately. oil pressure remained lower than normal, verified Oil was filled to manufactures specifications (changed June 30, 2025). Returned the vehicle to my place of residence as safe and slow as I possibly could and parked it as it is a major safety concern.

Unloaded my Denali at huge loss with 30,000 miles because gm wouldn’t fix recall after many times in shop, broke down on freeway, and need to travel to Canada on business. Canada won’t allow vehicles with open safety recalls to enter country even though im pretty sure engine was MADE in Canada. Gm corporate office told me there’s nothing they can do. While in shop for 4 days of testing i watched vehicle on app, never started, moved, just put out back for 4 days then told absolutely nothing. Just wanted fair trade in for diesel. Truck looked identical to brand new on lot, 10/10 except engine recall. Gm promised to reimburse rental fees when broke down a week or so, submitted documents to Gm, nothing recieved. Bought ram instead for obvious reasons. Is there a lemon law, class action, agency etc that can help compensate for losses? The public...

The contact owns a 2022 GMC Sierra 1500. The contact stated that after shifting to drive (D) and depressing the accelerator pedal, the vehicle failed to respond as intended. The contact shifted to park(P) and attempted to turn off the vehicle; however, the vehicle failed to turn off. The contact stated after several attempts, the vehicle turned off; however, the contact was unable to restart the vehicle. The contact stated that the "Service Engine" warning light was illuminated. The contact had the vehicle towed to a dealer. The contact stated that the tow truck driver was unable to shift the vehicle to neutral(N) to winch the vehicle onto the flat bed. The dealer had not yet diagnosed the vehicle. The vehicle was not repaired. The manufacturer was not informed of the failure. The failure mileage was approximately 17,000.

While driving on streets and freeways the truck will shift hard and then loss of acceleration and into limp mode. Lights all on dash go crazy like brakes, 4WD, fuel gauge and check engine light. It has done it 8 times now and has been in the shop 5 times with same issue. Major safety issue while driving 70 mile hour then governs it at 55-62 mile per hour.

The radiator needs to be replaced on the 3.0L due to a leak in the seam of the radiator. The dealer has stated that they have had a few in the shop recently due to the same issue. There are a lot of complaints online that have the same issue, and customers have had to pay $3000 for the same replacement.

Pulling away from a stop sign when we were driving, and when I started to excelerate the truck it just died. We were at a busy intersection and was able to pull off the road into a parking lot and had AAA come and tow the truck and took it to Poages Auto Plaza, Quincy IL. This could have been really serious had we been on a busier road. We tried to restart the vehical and it would not start. We are going to need a loaner vehical preferrably a Truck.

Due to GMC not having a fix for the safety recall to repair the potential engine failure, we are unsafe driving our car. This has been in effect since April and still no fix is available. We feel extremely unsafe driving this car due to this issue.

The incident occurred during a journey from Sacramento, CA, to Winchester, CA, a distance of approximately 486 miles in my 2022 GMC Sierra AT4, equipped with the recalled 6.2L V8 engine, which has accumulated around 61,000 miles. I was driving when a loud bang caught my attention over the music. After that, I heard swooshing sounds three times before the engine lost power. I was able to move over to the right shoulder throughout heavy traffic; I managed to make it safely. During the maneuvering of my truck to the shoulder, I noticed on the dashboard that the vehicle was telling me to shift the vehicle to neutral and start it. I shifted the vehicle to neutral, but it did not start. Upon inspecting the fuses and battery for any obvious issues, I proceeded to check the harmonic balancer for signs of engine seizing. The engine had completely locked up.

I am writing to formally lodge a complaint and request immediate resolution regarding my 2022 GMC Sierra 1500 equipped with the L87 6.2L V8 engine, which has been out of service for more than 30 consecutive days due to a recall-related defect. The vehicle is inoperable, and I have been informed by the authorized dealership that no loaner vehicle will be provided, with no clear estimate for when parts or repairs will be available. I have contacted both General Motors Customer Assistance and the local dealership to request a loaner vehicle. In both cases, I was informed that no loaner was available. I was advised that I could rent a vehicle at my own expense, and that GM would only consider reimbursement up to $44 per day, but only after the recall is completed and only if my case is deemed eligible upon review. This reimbursement policy—requiring me to first...

Engine has had recall and still no remedy for it. Paint is chipping off and back locks stopped workingp

I was driving and entering the highway the truck lost power and acceleration was very slow, the engine fan runs 100% of the time, the check engine light comes on.

The coolant control valve is defective and the part is on back order with GM and dealer can’t tell me when part will be available because General Motors doesn’t know. Dealer has had my vehicle for three weeks and because of GM can’t tell me anything new.

GMC has failed to offer a solution to this major engine defect. In talking to two dealerships they are unable to perform any tests at this time that would in fact identify the engine as defective. We hear a knocking lifter but GMC has not acted in a timely manner I called the GMC line (Reggie) and was told there is no remedy and no known information as to when a remedy will be available. I even told one dealership that GMC had backed out of changing the oil viscosity because it had made problems worse.

Truck has failed coolant control valve. Unable to get replacement part. Truck is still under factory 3 yr 36,000 mile warranty. Truck has been in the shop but was not advised not to drive vehicle. Have had multiple instances where cooling fan is stuck on nigh and get reduced engine power message limiting power while driving. Also took truck in for recall that is currently on it and dealership failed to address recall it was scheduled for.

My engine developed a tapping sound about 10,000 miles into owning it. Wasn’t throwing any codes and it wasn’t extremely noticeable. I have been a mechanic for 20 years and knew something was wrong. Brought it to the dealership. They refused to investigate further due to no codes being on the computer fast-forward to 74000 miles on the vehicle. The engine locks up and leaves me stranded six hours away from home. Yes, the oil was changed religiously throughout the engine’s life, and all service was done through the dealership. I went back and forth with GM for weeks and they still refused to replace the engine on their dime. I was forced to come out of pocket 13000 dollars to replace the engine. Due to the warranty being out by 14000 miles. GM COULDN’T EVEN TELL ME WHY IT EXPLODED AND COULD NOT ASSURE ME THAT THE SAME ISSUE...
