general problems of the 2022 GMC Sierra 1500 - part 1

I purchased said vehicle with a little over 76,000 miles on xxx from NW Chevrolet, [xxx]. Dealership service the engine on xxx and remained on their lot until it was sold. While driving home, I smelled gas fumes coming into the cabin and the engine was misfiring causing slight hesitation in motor acceleration while adjusting to speed limits and climbing hills. I told management at the dealership about these issues on xxx. My vehicle is currently in the shop to fix the fuel injection system, spark plugs, grounding issues as of xxx to fix the dealerships mistake costing more out of pocket expense. Management will not do anything about it because it was sold (as is) without a warranty which I refused to purchase through finance and interest charges on a car loan. I purchased a 4-year warranty through endurance on xxx with a 30 day wait period before filing a claim. Gm is letting their dealerships advertise and sell problem vehicles with known motor issues to consumers while marking up the sale price. Vehicles should never be sold until gm fixes all motor defects before advertising to the consumer. The consumer is at serious financial risk when getting an auto loan paying on a broken vehicle.

Engine failure.

My truck has the same issues for the transmission and engine problems I have taken it to 4 dealerships and they all say the same thing. The first one I spent about 3 hours there and they changed the 20 oil to the 40 oil and said that will fix the issues but it hasn't I called GMC to report this and they sent me to the others but they said it's been looked at and I know one of them didn't do anything to see the issue. GMC called the other day and I told them I will let the engine locked up or the transmission keep doing the same thing and they'll have to fix the issue then. I do have 109000 miles on it but thus issue has been going on for 4 years they said I have 150000 miles for the issue but I do t think that is right. I paid them cash money for the truck when I bought it.

Had a prior recall a few months back on my truck in reference to the engine. My truck didn’t have an engine issue such as check engine light etc etc etc which required attention. So they only changed the oil to a different velocity. On Sunday afternoon August 23, 2026 while driving on interstate 20 near longview, texas the truck shut off. I had to get it towed to the chevy dealership (peltier chevy in tyler, texas).

The oil recall on my truck has been completed, but the low oil light still comes on. They changed the weight of the oil stated that it didn’t fall under the engine replacement recall. All that was done was a new oil cap and change weight of oil. Did not solve anything.

I got the vehicle with 60,000 miles 8,000 miles in vehicle gave me problems gave me a check engine light code p0300 then took it to get inspected then was told it was the fly wheel then it’s started knocking vehicle is currently not being droven because of the fly wheel.

While traveling northbound on the I 10 freeway my vehicle wouldn’t accelerate once pulled over to the shoulder the vehicle completely lost all acceleration and shut off. The vehicle smelled like burning plastic and would not restart. The dealership’s reporting engine fail.

The vehicle’s engine suffered a catastrophic failure and locked up while in operation. The engine is still installed in the vehicle and is available for inspection upon request. The engine suddenly locked up while I was driving, causing the vehicle to lose power and become disabled in traffic. I was forced to get the vehicle out of the flow of traffic and have it towed to a safe location. The sudden engine failure created a significant safety risk to me and other motorists, particularly because the failure occurred while the vehicle was being driven. Yes. Integrity Buick GMC in chattanooga inspected the vehicle and confirmed that the engine had locked up. Only the dealer. No.

I bought this truck from a dealer at the end of July 2026 and it only had 27k miles on it. I got the carfax and saw all the times of service and checked that this truck was inspected and went to the new oil type, filter and cap. It also was showing it had the special warranty due to recall. So I assumed everything was good to go and the truck was relaicle. Not even 18 days later and less than 800 miles I broke down mid drive. I was traveling at 45 mph and lost all power and almost caused an accident trying to get over and parked safely. There was no warning light or indication of it breaking down or having a mechanical issue. It went to the dealer and they diagnosed it as complete engine failure due the issue gm is having currently. They did order a new motor and it took two weeks to get in but they are in the process of the engine swap as we speak. I am sure I will get more details this week. . . . But I am concerned now amd honestly wish I wouldnt have bought this truck considering I am seeing reports of new motor swaps having catastrophic engine failure two or three times. So at this point im in limbo waiting for the new install and hopefully it doesnt fail again.

I just had to put my 4th engine in my 22 sierra at4 with the 6. 2 v8. I currently have 103k miles.

Vehicle was traveling at 65 mph on a busy highway when vehicle engine stopped. A message on the dash appeared indicating to driver to shift to neutral and try to restart engine. As vehicle was quickly loosing speed it was decided to coast to the side of road to avoid someone running into vehicle causing multiple cars to crash. After stopping vehicle, an attempt was made to start vehicle. Engine would not turn over. Vehicle was towed to dealership. The following day I was informed that the engine needed replacement.

Early this year the crankshaft seized while driving. The engine was promptly replaced and I carried on my way. Then 7k miles later, the replacement engine that gm sent also blew up and was a total replacement. Hopefully the third engine lasts longer.

Engine was replaced by classic GMC in katy/houston, TX in Dec 2025 under l87 recall. My wife was driving and was stopped on an off-ramp but still in the traffic lane. It started with a light knock that I thought I heard the day before, but then died on freeway within maybe 15 miles of her driving. Unknown if it knocked louder, but wife says she never heard anything until it died and check engine light came on and engine would not restart. Required tow to GMC dealer. They diagnosed and took 2-3 weeks to source and replace the engine. In July 2026, started hearing very similar noise - this time apparently the water pump seized. Heard noise and got home within about 10 miles. Checked under hood and drive belt was significantly frayed and knocking/metallic noise was intense. Towed to classic GMC. Not covered under any warranty - my replacement engine did not include a new pump. Cost $1700 at classic GMC - they said it had no relation to the engine replacement or labor done in December. Unrelated, but icing on the cake - less than 2 hours and 10 miles of picking it up from service, lots of warnings about lane keep, adaptive cruise control, and park sense started going off. Returned to same shop the next day and *poof* the camera and processor that runs all those systems was somehow fried. Unrelated of course. $1200 a but they claimed gm graciously offered to “split the cost with me 50/50” since I just paid so much for the water pump. Picked up from service and traded vehicle in with 2 days.

Vehicle has been maintained at gm authorized dealership according to manufacturer recommendations. 6. 2l recall was performed as recommended by manufacturer at approximately 25k miles. Engine failed at 36000 miles. The failure created a safety situation where vehicle suddenly lost propulsion power on the interstate. Gm replaced the engine with a remanufactured engine. Vehicle was out of service for approximately 90 days. My family has lost confidence in the vehicle and unfortunately because of the now known issues with this engine the vehicle has lost significant value, making it nearly impossible to trade the vehicle in for something reliable.

I was driving to work on 7/20/26 and my vehicle loss engine propulsion , engine failure and unable to restart vehicle and shift gears.

I purchased the vehicle on may 29, 2026 and it stated the 6. 2 liter engine recall had been fixed and that I have extended special coverage for the exact issue of the recall until 150008 miles on this vehicle. On July 14, 2026 the vehicle was being driven and stalled out at a traffic light and restarted, yet within a quarter mile it stalled again at the next traffic light and became completely disabled, it would not even allow a shift into nuetral, so I had it towed less than 100 feet into the walmart on loudon road in concord, nh 03301 parking lot. On July 23, 2026 I was able to get the batter charged and attach a code scanner which showed one code (p0016). Pursuant to recall n252494001 (which had allegedly been repaired, likely with the bandaid fix of thicker oil) any 6. 2 liter gm truck with the loss of propulsion needs to be plugged into a scanner and if code p0016 is present, engine replacement is needed. Specifically noted to the recall is special coverage n252494003 which provides the coverage to 150,008 miles on this vehicle is directly related to the recall. At the time of loss of propulsion the vehicle had 99,195 miles present on the odometer. The following day July 24, 2026 I had the vehicle towed to banks Chevrolet GMC in concord nh, after the vehicle arrived, I spoke with the service department, provided them with the recall paperwork and printout of the special coverage uner the VIN as well as a photo of the odometer and my scanner displayining one code p0016. They then informed me it would take them until August 24, 2026 to "diagnose" the vehicle. The recall is clear it just needs a code scan if disabled. I have contacted gm and informed them of the need for a loaner as the vehicle is a vehicle utilized for business. I have since been told they will try to look at it earlier and no loaner will be offered but I "may" be able to be reimbusred $44. 00 a day for a rental. There are no rentals for that price that can tow over 9500 pounds. It is unnacceptable.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving uphill at an undisclosed speed, the vehicle stalled and failed to return to normal operation. No warning lights were illuminated. The vehicle was towed to a dealer to be diagnosed, and the contact was informed that the engine needed to be replaced; however, parts to repair the vehicle were unavailable. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 83,000.

I was driving at 45 mph and all of a sudden the screens went black as if the truck was turned off and the first thing I did was turn on the hazards because I didn’t know if the engine shut off either there was on coming traffic from both my front and back so I was scared my truck shut off 5-7 seconds later the screens turned back on and everything went back to normal but I was scared that my truck just turned off I made the dealership aware of this issue as soon as I pulled over and they said they had a busy schedule and that they would try to have a manager reach out to me to “squeeze me in” mind you I just got my truck back from the dealership due to electrical issues and service yesterday and not even 24 hours later this happened so I am upset.

Loud knocking noise started while motor is running. Took to dealer who confirmed the noise and inspected. Metal confirmed in the oil pan and throughout motor. Service advisor said a new motor will be needed and has sent info to gm. This vehicle was checked per the recall and passed the pico test. Oil was changed to new gm 0-40 by dealer.

On June 1, 2026 driving eastbound on I-64 in louisville, ky. Engine shut-off warning popped up and engine immediately shut off. There were no prior warnings or unusual engine or noises. 3 passengers in car. Had to change 2 lanes and then onto shoulder while coasting and slowing down. Car was incapacitated and gave battery and 0% oil read. Oil is changed regularly and engine recall work had been performed on truck several months prior. Car at dealership, not analyzed or repaired yet.

On November 20, 2025, my 2022 GMC Sierra 1500 at4 equipped with the 3. 0l duramax diesel engine began experiencing intermittent engine overheating conditions. Concerned about a potential safety issue, I contacted a GMC dealership and was advised that because no diagnostic trouble codes were present, there was nothing to diagnose or repair and that I should continue driving the vehicle. Over the following months, the overheating condition continued intermittently. On may 24, 2026, while driving on the highway, the vehicle suddenly overheated, displayed fault code p1098, and entered reduced power ("limp mode"). The vehicle lost normal performance and acceleration while traveling in traffic. This created a significant safety hazard because the vehicle was unable to maintain normal highway speeds, increasing the risk of a rear-end collision or other traffic accident. The loss of power occurred while driving and without sufficient warning, leaving the vehicle unable to safely perform as expected in highway traffic. After researching this issue, I found numerous reports from other GMC and Chevrolet owners describing similar overheating, coolant control valve, thermal management system, and p1098-related failures. Many owners report symptoms involving engine overheating, reduced engine power, and limp mode operation while driving. I am concerned that this may indicate a broader defect involving the vehicle's cooling system and thermal management components. The vehicle exhibited overheating symptoms for approximately six months before the final failure occurred. Additionally, I understand that certain gm vehicles have been subject to service actions involving coolant control valves and thermal management system components. Given the similarity of symptoms, I am concerned that the overheating condition reported in November 2025 may be related to the same type of failure mechanism, yet my vehicle has not been included in any recall or special coverage program.

Our truck has the gm 6. 2l v8 engine in it. We had the “recall” done where they recommended thicker oil. Despite that recall work we still had catastrophic engine failure and gm’s solution is terrible. A new engine that can have the same issue?.

I am reporting two separate stall/loss of propulsion events on my 2022 GMC Sierra 1500 denali limited (VIN: [xxx] ), which is subject to NHTSA recall #25v274000 and gm special coverage xxx (l87 engine loss of propulsion). Incident 1 — April 16, 2026: while decelerating off a highway exit ramp, the vehicle stalled without warning. The dashboard prompted me to shift to neutral and restart. I performed a rolling restart successfully and continued driving. This stall occurred while decelerating on a highway exit ramp with vehicles traveling at highway speeds behind me. The sudden and unexpected loss of propulsion created a significant rear-end collision risk. Incident 2 — April 17, 2026 (next day): while traveling at approximately 40 mph and climbing a hill under load, the vehicle stalled a second time. The dashboard again prompted a neutral restart. This time the vehicle would not restart. All I heard was a single click from the starter, followed by a complete dash reboot. The vehicle lost all power repeatedly upon restart attempts. I was stranded on a narrow, high-speed rural road in standish, maine during rush hour, with vehicles passing at speed. I was in serious danger. The vehicle was towed to weirs GMC in arundel, maine (the selling dealer), where it currently remains for diagnosis under ro# xxx. Both stall concerns are documented as warranty pay. Additional concern: since the day after purchase (March 28, 2026), I have noticed a pronounced cold-start tick originating from the bottom end of the engine, confirmed by an independent mechanic as coming from inside the engine. This vehicle passed a recall #25v274000 inspection on December 28, 2025 at 98,233 miles. The tick and stall events began after that inspection. I am requesting this be formally documented as a safety complaint tied to recall #25v274000 and special coverage xxx. Information redacted pursuant to the freedom of information act (foia), 5 u. S.

I have the gm 6. 2 l engine in my 2022 denali and had the recall pico test performed August 20th 2025 and the truck passed, they changed the oil and cap and I was good to go supposedly. 5,000 miles later I had the oil changed again and everything looked fine, I drove the truck another approximately 1500 miles and the engine suddenly seized with no indications and no warning. That occurred on April 12th 2026. It is now may 3rd 2026 and I am still waiting for an engine.

We were driving down the interstate at speed and the engine shut off unexpectedly. The truck flashed a notification on the dash asking to turn it back on. Pressing the on button would not turn the truck on. The tow truck company also couldn't get it to shift into neutral so he had to drag it up the tow truck after getting towed to a dealership they told us they had no one to look at it that day so we got a hotel room 5 hours from home and in the morning they said the engine is siezed and will need to be replaced.

Coolant control valve failed. Seems to be a known issue with year make and model but not all VIN have been approved for special warranty despite occurring on same vehicle.

I own a 2022 GMC Sierra 1500 at4. The vehicle developed a clear engine knocking noise. I first brought the vehicle to the dealership while under 150,000 miles for inspection related to a recall. The dealership only performed a computer scan and oil change and stated no issue was found. No mechanical inspection was performed despite the noise. The issue continued and worsened. I returned to the dealership and the vehicle was kept for three days. During that time, the dealership again denied the existence of the noise and stated the vehicle was operating normally. When I picked up the vehicle, I immediately noticed the same noise and requested the technician to inspect it again. At that time, the technician acknowledged the noise and confirmed it was related to the recall. Despite this acknowledgment, general motors declined to repair the engine and closed the case, offering only partial assistance toward purchasing a new vehicle instead of fixing the defect. The failure to properly diagnose the issue during the initial visit and the subsequent denial during the second inspection allowed a safety-related mechanical defect to worsen. This condition may result in engine failure or sudden loss of power while driving, creating a serious safety risk. The engine noise indicates a potential internal failure which could lead to sudden loss of power while driving, creating a safety risk. The initial failure to properly diagnose the issue may have allowed a safety-related defect to worsen beyond repair.

Ticking at cold start. 4/02/26 on way home from work. Truck loses acceleration while driving. Bug jumps then display says low power mode. Truck will start but will not move forward or in reverse. Rpms increase but no propulsion. Recall was performed 11/17/25 and passed inspection through romain GMC evansville, in. Called romain on 4/02/26 and was told someone would return my call 4/03/26. Still waiting. Plan to call kate faupal dealership in henderson,ky on 4/06/26.

16 year old was driving down the interstate, truck stopped accelerating out of no where and lost speed while in the middle lane. Steering wheel locked up, car showed oil pressure issue. Was told to shift to neutral and restart. Barely made it to the shoulder. App showed only a battery issue and no other alerts. Thankful we did not get hit as cars were flying by on either side on the interstate. Could have been a serious accident. The dealership confirmed that the engine needed to be replaced. Truck had full 50,000 mile service recently. Also, had passed the gm recall and were told the engine wasn't effected 9/20/25. No warning lights or issues prior. Completely out of the blue.

Motor spun a bearing on the crank and the vehicle is needing a new motor. 73,000 miles. Passed the gm recall inspection less than 6 months ago. Vehicle has had regular oil changes and all maintenance done on time. Engine started hard then started knocking. Made it to dealership for diagnostics.

Driving on the interstate at speed and all of a sudden a loss of power, christmas tree of lights on the dash and low oil pressure alarms. Engine now needs replacement.

I was exiting a main highway and when I let off the accelerator the engine died unexpectedly with no prior signs of failure and would not turn over to restart, luckily I was able to coast onto a side street out of the way of moderate traffic. I called gm roadside assistance and had the vehicle towed to my local dealership. The service department confirmed that the engine was seized and needed replaced. My vehicle went through the l87 recall and passed inspection last fall at 29,400 miles, had another oil change at around 33,500 miles. The engine failed at 37,800 miles. I am the original owner and have always maintained the vehicle to gm standards. I feel that the recall is not solving this problem, because the engines are failing anyway. At this time my vehicle has been at the dealership service department for three and a half weeks, and is waiting on the replacement engine. The dealership has provided a loaner vehicle.

While driving at 72moh, the engine started to knock/tick and then shifted into neutral indicating to press the start button again. Once I coasted to a stop, the truck shifted into park by itself and indicated to hit the start button again at which point it was completely locked up and inoperable. The vehicle had an engine replaced at 13,000 miles and currently has 54,000 miles on it. It now needs another complete engine replacement. The vehicle also had the recall inspection done in Dec/2025 and found no issues.

Vehicle burns approximately 1 quart of oil every 1000 miles.

While driving on the road the vehicle started sputtering and stalled! we pulled to the side of the road and tried to start the car but it rolled and would not start. We called a a mechanic who had it towed and found out that the fuel pump and the fuel control board had failed. Both have been replaced and the truck seems to be working again. Heard several other persons had this issue with their gcm sierra elevation so we wanted to report since there is currently no recall. Luckily the traffic was not going that fast or we could have had an accident and been seriously injured.
