general problems of the 2022 GMC Sierra 1500 - part 2

Transmission keeps shifting hard and stud stuttering at low speeds.

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.

Purchase a used 2022 GMC Sierra 1500 denali with a 3. 0l diesel at around 42,000 miles. Drove it for about 1,500 miles before I started noticing unusual shifting with the transmission which became more noticeable with time. At around 44,000 miles, the truck had two hard shifts going 35-40 mph on a flat round and put itself into limp mode. Turned off and on the truck multiple times, the engine light always stayed on but the symptoms would come and go. Either way the truck always went back into limp mode after a few miles. I did a quick scan and it came out with a p0700 and p0746 code. I limped it to the dealer and was told that it was a bad valve body which is apparently on back order with no eta and they can’t tell me when I will get my truck back.

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 contact owns a 2022 GMC Sierra 1500. The contact stated while driving 25-30 mph, the transmission shifted hard while depressing the accelerator pedal. The contact stated that while driving 75 mph with the cruise control activated, the vehicle hesitated with the message "service transmission immediately" displayed. The vehicle stalled and the contact coasted the vehicle off to the shoulder of the highway. Due to the failure, the vehicle was towed to an independent mechanic. While speaking with a relative that owned a similar vehicle, the contact was informed of NHTSA campaign number: 24v797000 (power train); however, the VIN was not included in the recall. The manufacturer was notified of the failure and confirmed that the vehicle was not under recall; the contact was referred to the NHTSA hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 100,200.

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.

While traveling at highway speeds in a very congested and busy segment near virginia beach virginia the truck began shifting erratically and suddenly lost power which required me to cross two lanes of traffic 30 miles an hour below the speed limit to get to the shoulder. Cars were swerving everywhere to miss us with this sudden loss of power and speed. The truck has been towed and now at the dealer where it has been diagnosed with a stuck/failed pressure control solenoid and the valve body must be replaced which is apparently on back order due to the high number of failures on the gm 10speed transmissions. Such a sudden loss of power and the reduced power mode of the software made the situation extremely dangerous at highway speeds in congested traffic. Something should be done quickly to get these vehicles off the road until a suitable fix is resolved as someone is going to get killed.

While driving on the highway at 75mph, the engine stopped responding to the cruise control speed it was set to. The vehicle started to slowly lose speed and the shifting was not normal causing the engine to rev from below 2000 rpms to about 3500 rpms, at this point the engine stopped producing power, the transmission was shifted to neutral by itself, and the check engine light illuminated. While I was able to move to the shoulder and put my hazard lights on, this could've caused an accident in a more congested area. No one was harmed or any accidents occurred. The truck would no longer start, at this point GMC onstar was called and they provided a tow truck to the nearest GMC dealership. While waiting for the tow truck, I decided to read the codes for the check engine light, p0016 and p0011 codes were populated. The codes were provided to the dealership. The dealership has since then confirmed the engine is seized and a new one will need to be installed. Model of the engine is the gm 6. 2l, which currently has an open recall against it for the crankshaft manufacturing defects.

I was on the way to the airport and my vehicle suddenly went into reduced power mode and had trouble shifting into gear. I pulled over, shut off my truck, and turned it back on only to have the problem continue. I was able to turn around and make it home, but the vehicle would then not shift into reverse. We had to push the vehicle so that I could position it in the street. Once we were back from vacation, I took it to a gm certified service location (my local Cadillac dealership). After review, they diagnosed a defective valve body and the engine recall. I’ve been informed as of today that my valve body will be $3,000 and gm will not cover it because I have more than 60k miles on the truck (it has 72k). After research, this is a common issue and it is ridiculous that gm will not escalate the issue and help consumers with this clear problem due to their manufacturing and/or design. The vehicle is currently sitting at the dealer waiting for a back ordered valve body and I have had to go out of pocket to rent a vehicle. Every service for the vehicle has been completed at a gm certified service location. It is available for inspection immediately, if required.

Complete transmission failure without warning, resulting in loss of power. Vehicle has been maintained meticulously by the book. There were no warning lights or cel before or during failure.

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.

Control valve engine coolant which is a well known issue with back orders taking months for the part and GMC not acknowledging responsibility and having loyal customers pay out of pocket.

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 should be warned!.

While stopped at a light at a busy intersection the truck wouldn’t drive. There were no prior indications to there be an issue, no noises, no check engine lights. The intersection is a multiple lane route with high speed and traffic with rear end collision possible. The truck was determined to have a blown motor.

A 2022 Sierra 1500 had a catastrophic engine failure while driving. The vehicle was unstable and came to rest. The issue has been confirmed base on the recall notice. The vehicle has been sitting at the dealer for three months waiting for gm to 'open' the recall on this vehicle. Customer service has been contacted on several occasions but the recall is still not opened.

Engine had already had a full replacement within the first 35,000 miles. Driving down the road at 55 mph and engine stops completely. Have to coast into a neighborhood. Luckily I was able to get out of the road. Pulled over and turn the truck off. Tried to start it and it never would turn over. Came back an hour later to see if it just needed turn off for a bit and restarted. Tried to start it and it started right up. Drove it around the block and then decided to drive to an auto store to test the battery. Before I could get to the store the truck shut off again while driving in the middle of the busiest road in town during rush hour traffic. Had it towed to the dealership and they said I need an engine replacement. This 6. 2 motor is completely unreliable and a hazard to anyone driving it. No warning lights, no indication it was going to fail. I keep up with all my maintenance. I drive under control and at the speed limit and I don't tow anything.

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.

Vehicle shifted strange than reduced power which forced me the pull off the road in a unsafe manner.

While driving on the freeway, my truck suddenly experienced a severe and unexpected downshift into first gear at highway speeds. Dashboard warning lights immediately illuminated, indicating multiple system faults. I was able to safely pull over and shift the vehicle into park. However, after doing so, the truck completely refused to engage drive or any other gear. This abrupt and uncommanded downshift posed a serious safety risk, not only to myself but to other drivers, due to the potential for loss of vehicle control. The vehicle had to be towed from the scene. It has now been at the dealership for over two and a half months, with no clear timeline for repair or resolution. This incident raises major concerns about the reliability and safety of the transmission system, particularly under high-speed conditions.

03/08/2025 while at interstate speed engine turned off as did the entire vehicle electrical system in the truck. Steering control was maintained (though not power assisted) and brake control was in the same position. Truck was brought to a safe position in the breakdown lane and a re start was attempted to find that engine would not rotate and a number of dash indications were displayed including check engine. No indication of low oil pressure light nor any other warning was displayed prior engine shutdown event were noted. Truck was taken to an independent repair center for evaluation. Initial inspection noted that engine would neither turn via electric starter nor by manual rotation of crank shaft with a socket and breaker bar. Truck may be inspected near owners residence. Safety risk was low due to the low traffic condition of the interstate travelled at the time.

I suddenly lost all power in my pickup. I'd try to accelerate and it would just lag and then all of a sudden it would gain power and take off. It wouldn't shift gears and I could not go over 30 mph, as it was running at about 2-3000 rpm. Once I was in a safe spot to stop, it would not shift into manual or reverse.

I had complete engine failure due to rod bearing failure resulting in the engine locking up and leaving me stranded on the road in 20° weather while waiting 2 hours for a tow truck. My safety was in jeopardy when this happened due to the extreme cold and being stuck on the side of a very busy highway. There was no warning and no warning lights on the dash prior to the engine failure. The engine in my truck is the l87 which is gm’s 6. 2 liter v8. Once the truck was towed to the dealership they told me it was completely locked up and the needed a complete engine replacement that took over 8 weeks. Dealership told me the seized engine would be sent back to gm so they could inspect it for causes on why the rod bearings failed resulting in the seizure of the engine.

Truck died and had to have it towed to the dealership. They called me and told me they engine had seized from from bearing failure.

The contact owns a 2022 GMC Sierra 1500. The contact stated that while her husband was driving 30-35 mph, the vehicle stalled. No warning lights were illuminated. The contact's husband was able to pull over onto the side of the road. The contact's husband attempted to restart the vehicle, and the vehicle failed to restart. The vehicle was towed to the dealer where it was diagnosed and determined that the engine had seized and needed to be replaced. The contact's husband stated that the tow truck driver could not move the gear shifter into neutral(n) when the vehicle was being towed. The vehicle was not repaired. The manufacturer was notified of the failure. The vehicle remained at the dealer and had not been driven since. The failure mileage was 81,000.

Coolant control valve failure (p1098) after 50k service. When this engine code appears the vehicle goes into reduced power mode. While it does this at inopportune time and creates potential for colission with other vehicles such as when merging with traffic. The coolant control valve is a known issue and gm has just recently recalssified it from their powertrain warranty to their much shorter bumper to bumper or emissions warranty without notifity owners of this change. This move directly puts owners and drivers at risk while on the road. Gm should be accountable to resolve this problem as failures are across multiples years and are happening to vehicles at all milages with some less than 5k miles. This is an obvious failure on their part and they should be required to rectify the situation.

The contact owns a 2022 GMC Sierra 1500. The contact stated that after shifting to park(p) and turning off the vehicle, the message "shift to park" remained displayed on the instrument panel, with an audible chime coming from the vehicle. The contact was forced to use the key fob to lock and unlock the doors several times to correct the failure. The dealer was notified of the failure and an appointment was scheduled to have the vehicle repaired. The manufacturer was notified of the failure and provided the contact with a case number. The contact was then referred to the NHTSA hotline to report the failure. The vehicle was not repaired. The failure mileage was unknown.

On or around January 27 2025 my 2022 sierra loss power and shut down at night and dropped to 0 rpm. I was close to the house and got pulled home by relative. When I did get it cranked lifters were tapping which was common in the 6. 2 but I drained my oil and filter and saw the glitter look. Truck was still tapping after warmed up. Last night I about got hit at an intersection when same thing happened. I felt a jar, and truck went to zero rpm and loss power. Truck said, put in neutral and try again. When I pushed starter had a click. Then I pushed start again and it started smoking. It burnt my starter up, because engine is seized. I saw where there is an investigation on this and I really hope it goes through because that was a scary moment and it is safety concern. Twice the same thing. But now can’t turn crankshaft, nothing to drive, making payments on a 80,000 truck that is my personal and work vehicle. 92000 miles on my truck and have my oil changed regularly. I’m stuck between rock and hard place, but will be getting it towed to a dealer somewhere. To here I need a 6. 2l engine in my sierra slt. 2 year old truck it is stressful. I know im going to here 10,000 $$$ I don’t have.

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.

Used my truck to back out of the driveway and wouldn't go into reverse at all. Towed to dealership and said problem was transmission valve body went bad. Dealership said tvb fail all the time in these trucks. They told me that this part is on back order and could be 2 or 3 months to get part in. Gm has and known transmission issues . This truck is little over 2 years old and only has 40k on it. I'm hearing that tvb are failing while driving and creating dangerous situations and gm isn't doing anything about . Truck is under pt warranty. I asked what can't gm just put a new transmission in? they say it's not cost effective. So cost is over safety I said!.

This is in addition to the first report regarding my 2022 GMC sierra slt with 10-speed transmission. I had previously filed a complaint (nhsta tracking# 11728418. ) regarding the onstar and internet quitting on me. Which was the serial gateway module. I had reported that I was put off many times regarding a loner vehicle so I could get back and forth to my oncologist for treatment of head and neck cancer. And years of follow-up appt. With specialists gastrointerologists and cardiologist for serious issues incurred from 168 intense radiation treatments and chemo. I had also taken my truck in for all scheduled maintenace intervals specified by the dealer and the manufacturer. "repair order gccs504610" I had to leave it in the shop for 30 days for a defective exhaust system, radio, charging port, remote key fob not able to unlock the truck so I could get in. And some other warranty/recall issues regarding my a/c blower and seat cushion blower motor and trailer brake switch, fog lamps running while daytime running lights were on - all safety issues, my truck was @ beck & masten GMC for 30 days during these repairs, recalls and warranty. Will attach invoice 123532 to show consistant sheduled maintenance per GMC guidelines. Waited while this service was performed. "repair order / invoice 140542" again my truck was back at beck & masten GMC (19 days) for the serial gateway module and radio not working again! again, no onstar, no internet, no gps. And, I reported the oil consumption and add oil light coming on; which was dismissed as idling too often (. I had to add 2 qts of oil between scheduled oil changes(the truck had only 13754 miles at this time) the last time I had anything to do with beck & masten GMC south was when I spent over months waiting on a loaner vehicle because I needed them to please look into still having an oil light coming on. And slipping and front end wobble just before the slipping/clucking and high rpm's that were dangerous- accident!!.

Engine - catastrophic failure 6. 2 liter v8. Vehicle is currently at dealer awaiting full engine replacement. Failure left me stranded waiting for tow to dealer. Problem has been diagnosed as rod and main bearing failure, engine replacement imminent. Vehicle was running perfectly fine all day. Went to take my daughter to basketball practice in evening initially everything was fine, then we heard squeeking, turned around to bring right back home, lost power in intersection, truck stalled. Got restarted check engine light came on and limp mode reduced power activated. Truck towed to dealer and oil pan was pulled. Rob and main bearings have scattered metal throughout the engine. Truck confirmed to need full replacement.

My 2022 sierra denali shows message "shift to park" when turning off, even though it has been shifted to park, the dashboard stays lit as well as the radio on. Horn even goes off alerting as if the engine is on and me walking away with the key in my pocket even though engine is off. Have to play with shifter to get it to stop, sometimes turning it back on and off will do trick. Locking it with remote works most of the time but when this happens, I can't use remoteless key access, door just won't lock.

The contact owns a 2022 GMC Sierra 1500. The contact stated while her husband was driving 40-45 mph, the vehicle experienced reduced engine power and failed to exceed 30 mph. The driver was able to pull to the side of the road. The driver turned off and restarted the vehicle. The contact stated that upon shifting to reverse(r), the rpm decreased, and the vehicle failed to respond. The driver was able to drive to the dealer, where it was diagnosed that the transmission had failed, and there were metal shavings inside the transmission. The dealer determined that the transmission needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact that the VIN was not included in a related recall. The manufacturer referred the contact to the NHTSA hotline for the VIN to be added to a recall. The failure mileage was approximately 90,000.

While driving at 65 mph, the engine locked up, the truck went into neutral, and all power was lost. This occurred with no warning at all. The truck was towed 40 miles to a GMC dealership for repairs. GMC dealership has indicated that the engine is permanently locked up and will have to be replaced. The dealership did not provide any explanation as to why the engine locked up.

When the truck reaches approximately 50mph it is unable to shift into the next gears and then it's unable to downshift. The transmission will not go into neutral. The truck must be stopped and turned off, sometimes it will need to be restarted 2x before it's able to shift into first gear. The outdoors temperature was approximately 24f, transmission temp was 178f. The truck locked into 7th gear 6x in a row while the transmission was set to normal driving mode. There were no signs of transmission failure until the vehicle reached approximately 50mph, afterwards the check engine light illuminated, a warning stating "reduced acceleration drive with care" and "service transmission now unable to shift soon". The trucks rpms were approximately 2500rpm while driving 45mph and would not go down because the transmission would not shift up or down.
