general problems of the 2022 GMC Sierra 1500 - part 2

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.

My truck lost power while driving on the interstate. . Had to restart while traffic moved around me. . Truck eventually restarted and then again died while getting off exit ramp in traffic. Towed to dealership and was diagnosed with a "blown" rod bearing. Full engine replacement.

I reported problems with my truck to beck and masten south GMC. I was put off a number of times with ridiculous excuses. My vehicle sat in the shop for a month to get my onstar safety equipment repaired. I also had arguments with them regarding the oil light coming on and it burning excessive amounts of oil. I was told this was normal. I know better. Also, I needed to get it back into the shop for service and inspection for a squeeling noise under the hood. And to have them check the oul consumption. I was told it idle too often, and this was the reason oil was dissapearing. I was told they would put me on the loaner list so I could have means to get to my oncologist for cancer care. Well, I called numerous times because they never furnished a loaner for these issues I was told a third, then forth time I was next in line for a loaner so I could drop it off for repairs and recall work. After 8 months of these lies I finally went to monument Chevrolet. Beck and masten never intended to help me. Total I had tried and was told by newer service advisors, the manager, and GMC this would be remedied over 10 times in over 6 months. I finally gave up and moved on to never return to this dealer I had purchased two brand new GMC 1500 trucks from in a two year time frame. I did get my onstar gateway repaired by replacement. It had stopped working again,shortly after getting it back. I kept getting put off. They stated it needed another gateway for onstar. I kept calling,and was told they would contact me ince it came in. I ended up troubleshooting the entire modem/router assy. I found inconsitant configuration parametrs. So, I reconfigured it all from start to finish after clearing the memory by taking battery cables off and allowing it to power down and clear memory. Then I did perform a reconfiguration and username/password change as well. I repaired it myself. The onstar has never acted up again. These were my first issues. I had to take it to monument Chevrolet for service.

The transmission on this vehicle has given me problems. I have had the vehicle in a certified garage many times with complaints of a hard shifting transmission. First Chevrolet told me “it’s normal” but there is nothing normal about jerking so hard it throws a drink from a cup holder. Then I was told I needed a transmission wash. That was about $500 for it to “fix” the problem. Chevrolet told me the transmission was may or may not work and it may only be temporary. In my case it has reduced the hard shifting transmission but it’s still obvious. Now when I drive I remove my foot from the accelerator when it shifts from 1st to 2nd. I also make sure to keep a spill proof lid on my coffee because I never know when the transmission may throw it out of the cup holder.

The transmission failed without warning. The truck jerked several times and wouldn't go forward, eventually stopping, putting the driver at risk of being hit or losing control. There were no warning lights or issues prior to this. It was towed to the dealer who knew immediately that the transmission valve body had failed. He said this is a known problem and in fact there was a service bulletin issued last year by gm. As of now he told us there are 2000 vehicles waiting for this part. The part has been redesigned because gm knew it was faulty. Our truck is still at the dealer waiting for the part after a month. Others have been waiting for months. Gm is not allocating the part for current customers but instead putting the majority in new vehicles even though they know there are thousands of vehicles less than 3 years old on the road and putting people in danger! the rest of us are left without a vehicle. You are welcome to inspect our truck at the dealership where it currently sits.

In the past 6 years I have owned 4 GMC 6. 2l trucks the first was a 2019 no issues great truck. The second unfortunately had a short life with another vehicle. In 2023 the third a 2021 denali 6. 2l truck at 34k began using oil and blowing blue smoke out the tailpipes. The dealer started an oil consumption test (like you couldn’t see it happening) so finally at 45k they tore down the engine and found worn out valve guides and scored cylinders. They ordered an engine the engine was installed and it failed in 25 miles come to find out it was not oiling on one bank, a second motor was ordered and installed it failed at start up. At this time it had been months that the truck was down. The dealer took a stand and moved me into a 2022 GMC at4 with 6. 2l with the hopes of removing the issue this truck was the internet sales managers truck that he had recently bought and had 15k on. We made the deal, well at 35k this truck begins consuming oil. The dealer once again starts the oil consumption test process. A couple of months ago. The truck now has 42k or so on it and on my last trip from atlanta to fort walton after the dealer just topped it off 2 1/2 weeks prior to the first 2500 interval of the oil consumption test, the truck burned 1 1/2quarts in less than 2k miles and the oil warning light comes on as we arrive in fort walton. I would like a resolution to this, I have invested a lot of money into what should be one of the most reliable trucks on the road and all I hear is gm says it’s not met their threshold of a problem and you should expect to have to add oil to a truck with less than 45k on it and it’s not a problem. It’s already been proven with the 2021 that gm has a problem, I as well as the other 100,000 or so individuals with this same engine and gm knows it’s a problem with the quality of the engine build. Gm has a quality issue and knows it but they are not addressing it, just making the consumer jump through hoops and not finding a fix in 5 yr's is bad.

The contact owns a 2022 GMC Sierra 1500. The contact stated upon accelerating and driving at approximately 5 mph, the vehicle violently jerked. The vehicle began to drive as designed, but the failure recurred. There were no warning lights illuminated. The vehicle was taken to the local dealer, who test drove the vehicle and experienced the failure, but the vehicle was not diagnosed or repaired. The failure mileage was approximately 52,000. The VIN was not available.

Transmission shutters and won’t engage into reverse when hot, rear backup camera intermittently won’t display on screen just get a picture of a camera on dash screen. Happens multiple times dealer charged me for diagnostics but didn’t even drive the vehicle to get hot.
