2022 GMC Sierra 1500 engine complaints
Page 6 of 10: complaints 131 to 160 of 270, newest first, as owners wrote them.
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 pay out-of-pocket without guarantee of repayment—has placed significant undue hardship, financial burden, and emotional stress on me and my family. This situation is especially frustrating considering the vehicle: Remains under GM’s lifetime powertrain warranty; Has been completely unusable for 59 days without replacement; Has left me with no reliable means of transportation, and Involves a known defect acknowledged by GM, yet with no definitive timeline for resolution. As a result, I am suffering direct and ongoing consequences, including: Out-of-pocket transportation costs; Disruption to daily life and mounting stress that no consumer should face after purchasing a premium, modern vehicle from a manufacturer of GM’s reputation. Accordingly, I am requesting the following: Provision of a comparable loaner vehicle immediately, or full reimbursement for a rental vehicle retroactive to the date the truck became inoperable; Compensation for loss of transportation and impact on life. If GM cannot resolve the defect in a timely manner, a full repurchase or replacement of the vehicle under federal warranty law.
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.
Engine has had recall and still no remedy for it. Paint is chipping off and back locks stopped workingp
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 WOULD NOT HAPPEN TO MY REPLACEMENT ENGINE. 2nd engine started to DO THE SAME THING AFTER 8000 MILES AND THE SAME THING HAPPENED AT THE DEALERSHIP. THEY REFUSE TO DO ANYTHING BECAUSE THERE WAS NO CODES. NOW I HAVE 30,000 MILES ON THE SECOND ENGINE AND I KNOW WITHIN THE NEXT FEW MONTHS IT’S GOING TO DO THE SAME EXACT THING BY THE WAY IT’S RUNNING. I’m disgusted. GM has personally put me in excessive financial strain and caused me serious anxiety. And now I’m driving around a ticking time bomb with no resolution.

The engine gave out without warning while driving on the highway at 70 miles per hour on April 11th 2025. Upon towing the vehicle to the local GM dealership, I was told the motor had blown and needed a full replacement. One week after, the recall comes out. I bought the truck used in 2023. I called the dealership I originally bought the truck from to ask about any past problems and was told this same incident happened to the original owner of the vehicle before it hit five thousand miles.
I was driving home from work one day my truck started. Losing power I could press the gas to make the truck drive it started slowing down
This truck is burning oil faster than it takes us to do an oil change we have to check it once a week to make sure it had oil in it. I have seen online I am not the only one having this issue this year make and model. I want to report this problem.
Engine locked up without warning while traveling 65 MPH heading [XXX] on [XXX] outside of East Dubuque, IL. I had now power and many lights on the dash lit up simultaneously. Luckily I was able to coast to a stop and get my vehicle mostly off the highway. I had to walk almost 3 miles in the snow and dark to get to town.

I was driving down the highway at 75 MPH; and noticed my traction control light come on. No sooner than the thought processed about the light my whole dash lit up and indicated engine light, Traction control system, and steering was difficult. I pulled over immediately and turned the vehicle off. I got out checked all the fluids “all were full and good” no leaks, cracks, nothing obvious I could see. I got back in and started the engine for a moment and heard a slight knocking on the passenger side of engine and felt a little vibration not present before. After getting it towed and not wanting to risk further damage I got the vehicle to a GMC dealer who then diagnosed that I had a failed lifter on my vehicle. This caused bent rods, leading to internal engine damage and I needed a completely new engine. The odometer reading was 68,231. I have not even had a headlight go out in this vehicle yet. All of my oil change records were up to date. It was past my warranty with GMC so they would not pay for it and wanted me to pay 10,700$ out of pocket. My insurance ended up paying for it. When I inspected the engine myself with a GM mechanic he told me that they have been having ALOT of issues with these lifters being stuck causing catastrophic engine damage. Obviously the 6.2 liter is noticed but my vehicle is a 5.3 liter V8. They believe it is caused by the AFM fuel saving feature where it goes down to 4 cylinders on highway speeds to save gas. This was a nightmare and I was without a vehicle for ALMOST a month to the day… exactly 29 days
We didn't know that the truck was having a low pressure oil problem, never showed a warning or check engine light, the truck stop all off the sudden without warning, and the engine was seized in the middle of a road,thank God we weren't driving in the highway .

The check engine light came on and the fan ran at full speed. The engine light is for a faulty coolant control valve which I've been told is a known issue and is on national backorder.
Driving 70 mph on highway and the engine shut off. Dash says shift to park to restart. Pulled over and put the vehicle in park and pressed engine start. Vehicle did not start back up. (No crank no start) Vehicle locked in park and wont shift. Vehicle was towed to my house. Replaced battery bus bar and vehicle started back up. Test drove and shut off again in my driveway. Will not restart. No engine light on. 124k miles on it. No warning of this happening. Vehicle randomly will shut off. Sometimes it turns on. Been parked since January in my garage for safety concerns until I learn of a repair.
Major engine failure with substantial loss of power while towing 24ft camp trailer. New engine has been installed. I was told by dealership that it was failure of engine bearings and connecting rods. They had seen a few similar cases
They’ve failed to remedy my situation. I called in twice and they told me there is nothing they can do yet even though I’ve noticed my engine lost power temporarily. Manufacturer Recall Number N252494000 the federal safety agency Recall Number 25V274
On December 12th heading to Bozeman at 88 MPH on I-90, truck completely died at high speed. We were going to have it towed to Billion in Bozeman because this was the cheapest route. We then got notice from your dealership that we had to tow it to Billings because Billings dealership never transferred the paperwork from Canada. $825.00 later we dropped the car per towing at Billings dealership. Monday, went to dealership and there was no word as to when his truck could get fixed. I was told by GMC that we would be reimbursed for the towing expense and since you did not have a loaner vehicle the 2 options GMC provided were to rent or car, reimbursed or GMC would cover our loan payment until the truck was fixed. Every week called dealership for an update and there was no update. I ended up calling Menholt-Chevy because I wanted to know what the average wait time was for this sort of problem. He said they had engines but it would be the same engine installed and if the warranty was through GMC, GMC would have to do the work. We were hesitant to even drive with this same engine again and possibly having the same situation happen again. Menholt suggested we trade the vehicle. They came up with a trade deal through his dealership on February 10th. February 12th AJ with Menholt had the vehicle towed to their dealership, exactly 2 months later. Ali, from GMC emailed April 2 stating they can no longer re-imburse us because we did not accept any incentives that were offered through GMC and that they tried to work with us and we did not accept any of their offers. XXXX and I were never offered anything, Period. We asked dealership for proof of offers and they could not provide any. I have never been re-imbursed and have been ignored from that point forward. The dealership has misinformed GMC and GMC and the dealership misled us. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
My camshaft failed only 1.8 years into having my brand new truck. GMC dealership repaired it so not sure if they have the part. My truck wouldn’t drive right causing everyone to be at risk. No warnings at all! I take very good care of my truck and the moment a light comes on I get it investigated. This repair was over 15000$ out of my pocket and they had to replace the engine entirely.
Below 10,000 miles my truck had the master brake cylinder to put which they repaired under warranty. At about 89,000 miles the engine went out stating a misfire on cylinder 2. After talking with GM the vehicle needed all the rods and cam shaft replaced which was almost an $11k repair of which I had to pay almost $5k. The truck still has sporadic shakes while at idle. Many other owners have complained of the same issues. It’s hard to understand that a new truck would have so many issues. The truck was also sold without the chip to heat the seats or the heated steering wheel. These were down afterwards one of them about a year after purchase. We feel GMC should have paid for this repair given all their engine issues. They changed the warranty from 100k miles to 60k miles because they knew these engines have major issues.
Truck was traveling through Atlanta when engine shut off and was not responsive. Was able to get truck off the interstate (I285 ramp to I75). Truck would not turn over. Pushed the ONstar button, they stated they couldn't diagnose the truck. They called a wrecker and got truck to a local GMC dealer(Capitol GMC). Truck was approx. 90 mile away from home. Dealer called on Monday 4/21 and stated that the engine was locked up and would need a new engine.
Coolant Control Valve malfunction causing fan to go on high. After several starts, engine light goes away but comes back sporadically. Safety issue is that when the light comes on it reduces the engine acceleration mid-drive. Coolant temp is normal but control valve is causing fan to turn on and reducing the engine acceleration.
The engine on my 22 Sierra began knocking at 23,000 miles . The engine i have is a 6.2. It was already scheduled for a front grill recall at the dealer and I had concerns for the knocking issues. I had no lights on the dash or a performance issue at the time. The dealer said they heard the knocking and wanted to take the oil filter off to confirm engine failure. The found metal shavings in the filter and it needed a new engine. They said if I kept driving it the engine would have locked up . Luckily I cought it in time and avoided an accident on the highway. This is a huge safety issue.
