general problems of the 2022 GMC Sierra 1500 - part 2

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.

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.

My 2022 GMC Sierra 1500 at4x experienced an engine failure requiring full replacement under warranty. The vehicle was out of service for approximately 46 days. After replacement, the vehicle experienced additional electrical issues and unsafe operating conditions. The replacement engine has now failed again in under 8,000 miles. A dealership performed diagnostic testing (pico scope) which failed immediately and recommended another full engine replacement. I have been advised not to drive the vehicle due to safety concerns. This appears to be a repeat defect that was not corrected by the initial repair.

Bought truck 0n 12/26/2025 from lot in michigan had it transported to missouri. First time I drive it check engine comes on and goes into "limp mode". Had it towed to gm dealer and they say it was the high pressure fuel pump. Got it back and check engine light comes back on then goes off then back on again. Not happy at all!!!.

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.

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.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while driving approximately 65 mph, the check engine and several other warning lights were illuminated. The contact stated that the vehicle almost stalled and then lunged forward. The vehicle was driven back to the residence, and a local dealer was contacted. The contact had taken the vehicle to a local dealer, where it was not yet diagnosed or repaired. The contact stated that the vehicle was repaired under NHTSA campaign number: 25v274000 (engine and engine cooling) by the same dealer. The contact stated that the dealer had tested the engine and added thicker viscosity oil. The contact related the failure to the recall work. The manufacturer was not informed of the failure. The failure mileage was approximately 25,000.

See attached document for complaint.

Engine seized while driving on my local interstate hwy. No warning lights came up. Towed to the dealer and they confirmed the engine was locked up. Engine needed to be replaced.

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 8 and 10 years old. Vehicle was towed that evening at 7 pm to the dealership, where it was diagnosed with completed engine failure.

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.

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.

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 engine stalled suddenly both times. A separate exterior trim piece, previously repaired under a recall, also detached while driving, adding an additional hazard. Both engine failures and the sudden loss of lighting and power created a clear and immediate safety risk to occupants and surrounding traffic. The repeated nature of the defect after a full engine replacement raises concern that the underlying issue has not been resolved.

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.

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 or unintended consequence of recall procedures, and because gm declined to investigate causation beyond procedural compliance.

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.

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.

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 engine, it compromised its condition.

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 truck was a part of the l87 recall inlcuding the 6. 2l engines. It passed their pico inspection. They changed the oil. I was driving down the interstate in memphis rush hour traffic with my daughter in the backseat and suddenly lost all propulsion. The dash said please start truck. I lost all power to the engine. I had to navigate high speed traffic and merge lanes safely. The cars stuck behind me, myself and family, and others nearby could've been in a wreck because of this issue. We were stuck on the side of the interstate waiting for a tow truck. It was towed to the nearby dealer where it sat waiting for the engine to be replaced for a couple of months. We are extremely lucky that the large trucks did not run us over. Gm has since replaced the engine with another remanufactured engine that is already making noises similar to the one it had before. What is going to happen when we are in an accident due to gm's negligence and continued issues with this engine?.

The contact owns a 2022 GMC Sierra 1500. The contact stated while driving, the vehicle decelerated unintendedly and failed to exceed 50 mph on several occasions. The check engine warning light illuminated, and the message " reduced acceleration - drive with care" was displayed. The vehicle was taken to the dealer on several occasions, and the onstar sensors, the fuel injectors and 8 spark plugs were replaced; however, the failure persisted. The vehicle was taken back to the dealer, who retrieved dtcs: p0747, indicating a pressure control solenoid a stuck on failure, and p0700, indicating a transmission control module failure. The dealer determined that the failure was related to gm special coverage number: n242454441 (momentary rear wheel lock-up); however, the VIN was not included. The vehicle was not repaired. The manufacturer was notified of the failure and referred the contact to the NHTSA hotline for assistance in adding the VIN to the special coverage. The failure mileage was approximately 95,000.

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

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.

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.

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.

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 "loaner vehicle". They stated "my truck passed the required inspection", which I knew they were being dishonest, but was forced to take the truck back anyway. Three days after taking possession I was on the interstate doing 60 mph and the engine totally seized up and almost caused an accident from the vehicles behind me running into me because of the sudden decrease in speed. I was able to safely pull over and had to get towed back to the dealership. This incident is beyond just a engine recall now because they new my truck was not safe to drive and forced me to take back my truck. Im just thankful I was driving and not my wife, or having my two grandchildren in the truck with me. To make mtters worse in this scenerio, this truck is actually my replacement truck because my 2021 truck had to be taken back per the lemon law in 2022, so this will now be truck #2 being lemon law and my original truck loan isnt even paid off. I have all of the various engine repair paperwork on this truck dating back to 2022.

Multiple times now my vehicle has had its engine locked up while driving at highway and regular uphill driving. Along with towing aswell. I have had it repaired multiple times and last time dealer wouldn’t tell me what happened because gm wouldn’t let them figure out what happened. Along with multiple attempts at fixing the transmission and brakes that are still on going issue. Same with the engine.

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.

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.

See attached document for complaint. Text from attached document: unacceptable delays in repair: we have contacted 2 local dealerships, both of which have informed us that the necessary parts are unavaila ble and cannot provide a clear time line for when repairs will be completed. Leesburg Buick GMC hummer (country Buick GMC at time of vehicle purchase) joyce koons Buick GMC (service manager: michael nguyen) • poor communication from we have received no follow-up communication from gm regarding the status of the recall or expected resolution. We have contacted gm twice by phone using the number provided in the recall notice. During the first call, we were transferred to a dealer in arizona- despite resid ing in virginia. On our second call, on 8/2, we were informed that our case had been escalated and that we would be contacted within 24-48 hours. As of now, we have not received any return phone call. • ongoing safety concerns: we are unable to drive the vehicle due to the risk of engine failure, which compromises our safety and that of others on the road.

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.

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.

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.
