2022 GMC Sierra 1500 engine complaints

While I was driving on highway, engine shut down and wouldn't restart. I needed to be towed.
I had taken my vehicle to the dealership for a front grill assembly recall by the end of the day they called me and said I needed to leave my truck at the dealership because of a coolant control valve and they don't recommend me driving it. They told me they would get me a rental car but we're not able to get me one until 11 days after my vehicle was in the shop. I told them I needed a truck for work but was told they could only offer up to 44 dollars a day and I'd have to take a vehicle that was given to me or pay out of my own pocket to rent my own. I had the case escalated but have yet to hear anything back from GMC if they have even recieved the part or what is going on with this backorder part! From what I've been seeing and reading this is obviously an ongoing thing with GMC they have known about this coolant control valve for years now but instead of producing them so they are no longer on backorder they continue to produce plenty of new vehicles to throw on the sales lot. I am out of thousands of dollars because I don't have a truck and only 2 weeks into this mess with GMC. The vehicle is paid off and I continue to wander when a part or gmc will give me a better option. So I can continue with my business.
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.
On [XXX] while driving 80mph on Westbound [XXX] , just West of the [XXX] exit, my engine simply quit. I was able to navigate it to the side of the highway to avoid traffic. However I could not restart the engine or subsequently get it out of Park gear. I got a notice "Conditions Not Correct for Shift." I was forced to use Onstar to get the truck towed back to the original dealership, Quebedeaux Buick/GMC in Tucson, Arizona. The next day, Monday, I went to the dealership to find out what happened to my truck. They said they would call me with results. They never did. The next day, Tuesday, I still hadn't received a call. I returned to the dealership to ask what had happened. They informed me the engine had thrown a bearing and it would need a total engine replacement. It would take 1-2 months. I'm now on day 4 of not having a vehicle, I've called the dealership every day to try to get a loaner vehicle, and they keep telling me they're working on it. The truck only has 36k miles on it and is still covered by warranty, but I feel like I'm getting the runaround from both the dealership and customer service. I still do not have a loaner vehicle.

I was driving at 60MPH on the highway and my engine failed. The dashboard read "Press Start to Restart" and my engine RPMs were zero and nothing happened when I pressed the accelerator. I was lucky to be driving in the right hand lane and was able to get over. I had to stop the vehicle in a tight area with a guardrail on the right hand side of the shoulder and passing traffic on the left. Luckily, my engine restarted. I got off at the next exit and the same thing happened. I was able to restart is again and get it home and eventually to the dealer. The vehicle has 29,500 miles on it and the dealer says it needs a new engine (L87). They say it could take 3 months to get it.
The motor blew up Safety I was going approximately 70 mph on interstate 80 could have been bad The vehicle is at a Chevy dealer The dealership has looked at it but has no idea when a new motor will arrive About a week before the ck oil light came on maybe a month prior to that when sitting at a stoplight, the motor started to shake
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 manufacturer was made aware of the failure and offered to pay a portion of the cost of the repair. The failure mileage was approximately 82,346.
Engine failure requiring engine replacement. I was told it was likely a bearing failure issue. I purchased the vehicle used from grapevine Buick with about 75,000 miles and decided not to purchase an extended warranty because I have always had good life and no engine issue with my previous chevy vehicles. There were no warning engine lights before, when it occurred or after it occurred. When the problem occurred on 12/2/24 I was driving on a road going approximately 50 mph when suddenly I felt a sudden loss of power. I then pulled over into a parking lot and could hear the engine knocking and making a screeching sound. I was over 230 miles from home when this occurred and had to get the vehicle towed back home. I had it towed again to an a shop where they determined the engine needed to be replaced. There was lots of metal shavings found in the oil pain. I was told it was likely a bearing failure issue. As I had no extended warranty and the factory warranty expired at 60,000 miles I had to pay over $12,000 for the engine to be replaced on a vehicle I had just purchased the prior month.
The contact owns a 2022 GMC Sierra 1500. The contact stated that while depressing the brake pedal, the transmission would downshift, and the vehicle was aggressively shaking while idling and while depressing the brake pedal. While driving approximately 35 - 40 MPH, the Electronic Stability Control (ESC) Service message was displayed, and the check engine warning light was illuminated. The contact was able to pull over to the side of the road, the vehicle was turned off for a while and then restarted to continue driving. The vehicle was taken to the dealer, who diagnosed that the crankshaft, bearings, and tie rods needed to be replaced due to engine failure. The engine was rebuilt and the vehicle was repaired. The manufacturer was not informed of the failure. The failure mileage was 86,636.
The engine went out while driving on the highway. Was driving around 60 mph. I almost gone to an accident. GM seemed like they knew of the problem but did not warn none of their customers of this problem. Car only had around 35,000 miles. GM however did swap out the engine. I want to sell and or trade it in, however the year and model lost its value due to the fact of the faulty engines.
repeated mechanical failures of my 2022 GMC Sierra AT4, which I purchased on October 26, 2024, with approximately 37,000 miles on the odometer. The adaptive cruse control is wonderful when it works but I have found even with the sensor clean the truck will slam on brakes on its own causing me to nearly be rear ended. It happens when driving into the sun and at night. I no longer trust adaptive cruse and use manual cruse. Within just 55 days of ownership, and after driving roughly 4,700 miles, the vehicle experienced a catastrophic engine failure without warning on December 20, 2024. This failure left the truck immobilized in a highly dangerous situation—stuck in the middle of a 65-mph highway at a red light, without the ability to shift into neutral and remove the vehicle from traffic. I was forced to activate the emergency flashers and exit the vehicle, standing helplessly on the side of the road while praying that oncoming drivers would see the truck in time to avoid a potentially deadly accident. The truck was towed to the dealership the following day, December 21, 2024, where it remained for an unacceptable 110 days awaiting a replacement engine. I finally took possession of the repaired vehicle on April 10, 2025. Shockingly, only two days later—after driving just 328 miles—the vehicle suffered a second catastrophic engine failure without warning. The truck is now inoperable once again, sitting in my driveway and in need of a third engine replacement. While the odometer currently reads 42,365 miles. This ongoing situation has been not only a major inconvenience, but also a significant safety concern and financial burden. I am extremely disappointed in the reliability and performance of this vehicle. This level of failure on a vehicle that is still under powertrain warranty is simply unacceptable.
I heard a knocking noise in my engine on 4/13/25 and took it to a dealer to diagnose on 4/15/25. I had previously had to have the engine rebuilt due a collapsed lifter at 70,000 miles and I was concerned that the noise was a precursor to a repeat of that problem. Instead, the dealer informed me that problem was a failed connector rod bearing and would require a replacement engine. The service manager said my truck was not safe to drive since it could experience a sudden catastrophic failure on the highway. The truck has 80,000 miles and has been serviced at every single required interval by the original selling dealer. There was no check engine light warning.
While driving my 2022 GMC Sierra Denali 6.2L truck, it somehow turned off. I placed it on neutral and tried to turn on, but it didn’t. I maneuvered to stop at the side of the road, but I was not close enough to the curb making it uncomfortable for others to drive around. I tried again to turn on the truck, but it didn’t. Before and after everything looked good, there were no symptoms or warning lights on the truck. I gave it a break and tried to turn in the truck, but it didn’t. I called GM roadside asst., and I got towed to the closed GM Services. They found out that battery was damaged, and an open starter fuse damaged. They changed the battery, the fuse block, and did the multi-point vehicle inspection (MPVI), and everything seemed good. I picked up my truck, and on my way back home the engine stopped running. At this time I get into a left turn lane, and I was able to stop before the stop line. This time I was in the middle of the road. I turned on the Hazard Warning Lights, but too many cars turning left pass through making it dangerous to my safety and others. I called the service department where my truck was serviced and GM roadside asst., and it got towed to the same service place. All this process was again around 2 hours in the middle of the road. They checked the truck, and found out that the battery was damaged, and an open starter fuse again. They changed, but this time they kept it on test to the next day and the starter fuse was damaged again. They found that the engine was locked, which is why the starter heats up and the amperage consumption increases, opening the fuse, the engine does not turn easily, the oil is at the correct level, it does not indicate low pressure in the initial driving test. They removed the oil pan and found metal particles in the oil and in the pan. After that they removed the rod bearings and can see that they are scratched and overheated, crankshaft scratched as well. Need order a new engine, oil cooler, oil cooler lines.
At 61k miles motor siezed. Took 3 months to get a replacement this was 10/24 got truck back Jan 25, drove 3k miles and motor is knocking. Been at dealer since 2/2/2025. Waiting for replacement motor.
While driving on a busy highway, the vehicle lost all acceleration. Seconds later, the entire truck shutdown. Lucky, I was able to get into the right hand lane prior to losing complete power, which allowed me to steer the truck onto the shoulder. It appears that an investigation has been launched into vehicles equipped with the GM 6.2L V8 L87 engine. This catastrophic engine failure not only put me in a fairly unsafe situation, it is costing me $13,800 to replace the engine on a 2022 GMC Sierra Denali.

Premature Engine Failure, motor seized up while driving
Premature Engine Failure, Motor seized up while driving
On February 18,2025 I texted the imperial valley gmc technician because started hearing a motorcycle noise like and wanted to schedule oil change. Never responded. On February 22, 2025 while driving the the desert in the night we heard a loud noise, like when the tires get debri and the motor of the vehicle lost power. We pulled over as we could and the truck didn’t want to start. I called the dealer for an advise with no answer back. As I could I towed the truck to the dealer on March 6 and finally March 26 spoke to technician and the motor had to be replaced. Is on back order and it will take 3-4 weeks. I’m concerned because the truck didn’t gave any warning just left us on the road. I was really scared because it was deserted area and no traffic. Really unsafe in that truck.
On [XXX] I was driving East on [XXX] in Joplin , MO at 75mph when my 2022 GMC Sierra put itself into Neutral. I could not get the truck back into gear and I was slowly decelerating. There were no warning lights or indications of a problem. When I was coasting down the Interstate and trying to get the truck back into gear, I would get a message that said "Conditions not safe for shift" I took the nearest exit and coasted to a stop in the end of the exit ramp. Once I came to a complete stop, my truck shut off. It never started again after that. I was blocking traffic from [XXX] and had to stand there for 30 minutes waiting on a tow truck to move me out of the way so traffic could flow again. There was no way to get the truck into Neutral again so that I could push it. The tow driver thought I had a bad battery but wasn't able to jump start it. I had him drop my truck off at my office where I planned to install a brand new battery. A couple hours later, we determined that the battery was not the problem. Still no warnings or indications of a problem with the truck. I towed it to the nearest GMC dealer the following Monday. It has been there now for 5 weeks waiting on a new 6.2L motor that according to the service department, needs to be replaced. I was told this is happening a lot across the US right now, which is the reason for no estimated completion time on my truck. I understand there is currently no recall or lawsuit even though, from what I was told, this potentially affects 880,000 vehicles. I feel that the way in which my truck stopped was dangerous and inconvenient to me and those around me. I would like to know what GM is doing to try and get these vehicles back running again and how we know that the replacement won't have the same issue a few more years down the road when the warranty is long expired. Currently in a loaner car from the dealer but as this is a registered commercial vehicle, we really prefer the truck back. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (
Started my truck and the motor started knocking. Had it towed to the dealership and they said the motor was blown. Luckily I was in the parking lot at work when this happened. If the motor had blown while I was driving either to or from work on the interstate I could have wrecked. There were no warnings prior to the motor blowing up.
Was driving down the main highway in town when the truck suddenly shut off. No lights, no warning. Had the truck towed to the dealership and called my insurance company as I had recently had the fenders and hood repaired after having a fender bender in my front yard. The insurance company looked at the truck and inspected the motor and told me the motor had locked up. They said this was a common issue with the motor for my truck and they wrote a report about it. I emailed the CEO of GMC and requested help since my truck was just over the mileage that warranty would cover. Her assistant contacted me and agreed to check out the vehicle, investigate and determine a cause and see if they can supply assistance. After 6 months of investigating, they determined the crankshaft broke, but also told me the valves was a major contributor to that cause. They offered to discount the cost of a replacement motor. I declined, so they discounted it further. I declined again and they offered me one final offer of $7500 before tax for a motor and install. I had a quote from another local company for $6000 and told them no again. Her assistant said they could no further help me. I have the documents from my insurance when they investigated and I have the emails I sent but only 1 response from them. The rest of the communications was over the phone. It’s been a year and half and I still don’t have a running truck, but I have a 800 a month truck payment that I have to pay.
