During a drive home from dinner, my truck engine completely turned off. I was driving around 25 mph at the time. Car when into neutral and I pulled to the side of the road. Tried to restart the truck, but couldn't not. I had to have the car towed to a dealer. Just got confirmation that my I need a new engine. Then I found that the NHTSA is investigating GMC for this very reason, so I thought I'd file a complaint. * My truck is currently at the dealership, so it is not available for inspection. * While I didn't feel my safety was at risk, If I was driving on a major highway, I may have felt differently. * Yes, problem has been confirmed by a dealership. * Vehicle has not been inspected by anyone other than the dealer. * The check engine light came on at the beginning of the drive, engine failed ~10 min later.

The truck has 12k miles on it and a week ago a bearing rod in the engine failed without warning. An engine should not have significant issues like this after only 12k miles of use. The truck is now with Williams Buick GMC in Charlotte, NC and waiting for a replacement engine.

My truck without warning the motor seized and stranded me in the side of a major route. This happened while driving 55mph and lost power and coasted to side of road.

On [XXX], in the middle of a 600 mile road trip from Idaho to Southern Nevada, the engine failed in our 2023 GMC Sierra with just 23,060 miles on the odometer. We stopped for fuel and upon restarting the engine to continue on our trip, the engine was making a harsh metal on metal knocking. We called for a tow instead of driving further. The truck was towed 242 miles to the nearest dealership (GM Roadside refused to do the tow since it was 42 miles outside of their limit) by our AAA membership. The dealership in Las Vegas took 5-1/2 weeks to look at the truck to determine what had failed. They pulled the oil pan and found that the rod bearings for the #1 and #2 rods had failed. If we had continued on, the rods would have seized and would have lost power to the brakes and steering. It's been nearly three months now, and we have no resolution from GM. They have agreed to a "repurchase" on the truck, but we have not been able to get any details on the buy-back for over three weeks. We are still waiting.

I was driving my pickup to my farm. I was on a 4 lane divided highway, when i pulled into the left turning lane my pickup just randomly said "press Start/Stop button" so I stupidly did. The vehicle then shutoff or was already shutoff, I am not sure. There was no warning sign, dash lights, or weird engine noises. I would later learn the engine just blew up. The vehicle would not refire and I was forced to sit in the turning lane for 5 hours waiting for a tow truck. The highway was very busy and vehicles were buzzing past me constantly. Not a safe place to be at all! I could not get the vehicle into neutral or remove the parking brake. Multiple highway patrol officers stopped to help me and try to get the vehicle into neutral so we could pull it off the side of the highway to no avail. I crawled underneath the vehicle and disconnected the drive shaft, but then had no way of removing the parking brake. After many hours of waiting a tow truck showed up and my 1 year old pickup was drug onto it skidding the rear tires. The engine had around 12,000 miles. The vehicle went to a GM dealership for 4 weeks and got a new engine installed.

Going down beltway at 80mph on November 18 2024 the vehicle lost engine power. I had to drift vehicle across 3 lanes to shoulder and called tow truck to take to dealership. The dealership informed me that the engine had went bad and needed to be replaced. The vehicle had 63k miles on it and was out of warranty and they want me to pay 4k to replace.

Truck acted like it would not start several times in a day. Had battery replaced and it still did not fix the issue. Was told by dealership I would need to bring in and let them look at it. Was going to delearship and noticed a llight knocking in my engine then all of a sudden lost power. Was able to coast out of traffic and onto a curb. Truck would not start or even try, yet every light and such still worked. Had taken to dealership and this morning was told it was the engine.

I was driving along the freeway with my family of five. There were no warning lamps. There was an odd noise for about 10 seconds, and then the engine completely seized/locked up. I lost all ability to use the engine. I was able to come across three lanes of traffic, thankfully, without hitting anything without the ability to accelerate. GMC dealership inspected the car the next day. The engine is completely seized up. They are replacing the entire engine, but it has been a month without my car. They still do not have the parts available. We are fortunate. There were no other cars around us and I was able to steer to the Berm Across three lanes. This could’ve caused a catastrophic accident for my family.

While driving along [XXX] in northern Arkansas the on [XXX] my 2023 GMC Sierra Denali's 6.2 engine suddenly locked up causing us to pull on to the shoulder of the road - nearly causing an accident. The vehicle had 23000 miles on it at the time. We were towing a two horse trailer with one horse aboard. At our expense, we had the vehicle and trailer towed back to St. Louis, MO then to O'Fallon Buick GMC. The dealer replaced the entire engine under warranty with a used rebuilt engine. They have omitted the engine replacement from the vehicle history report in CARFAX. The dealer had handled a number of 6.2 engine failures prior to this one. The vehicle was serviced well within factory guidelines at the dealer. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

While I was driving, the dash screen read "Press start button" and suddenly the vehicle loss engine power and I had to veer to the far right lane. Luckily the cars around me swerved away. I had initially called OnStar, but when the police arrived they told me I couldn't wait for Onstar as I was impeding traffic so they called a local tow truck and they towed it to my house. From my house, OnStar towed it to the GMC dealership. The dealership stated the engine has locked up and needs a whole new engine replacement.

While driving at about 70 mph, the screens in the vehicle went black and the truck had a complete loss of power. The vehicle inadvertently braked to approximately 30 mph and went into limp mode. The check engine warning light came on and the service power steering warning light, the service transmission warning light, the low tire pressure warning light, and the traction control warning light all illuminated. There were also messages displayed on the instrument panel to Service 4-WD and Reduce Acceleration and Drive with Care.”

I was driving on a rural and narrow 2 lane road with next to no shoulder when my engine started losing power. There were no check engine lights or other indicators of failure until the final 2 seconds. At that point, a message popped up on the dash stating something along the lines that my engine oil was too hot and to idle the engine. 2 seconds later, at 50mph my engine died. That is scary enough, but I was also towing a 5,000lb+ trailer, it was -3F, heavy winds, and I had my 2 dogs with me. Thankfully, I kept my wits about me, remained calm, and made it to the side of the road. As mentioned, there was not much shoulder so this put me in great danger of being hit by careless drivers speeding by. The nearest police officer was an hour away, so I was in quite a predicament. Had this happened to most other people, the narrative would have ended much differently. Come to find out, this is a common issue with these 6.2l engines. So much so, that there is a backorder on the engines due to the high replacement demand. This poses extreme danger not only "in the moment" of failure, but also the environmental dangers/risks users are potentially exposed to, just as I was. This needs to be a recall as this is a substantial and immediate safety issue in my opinion.

Failing coolant control valve causing reduced acceleration warning and engine overheating. Replacement parts unavailable from GM. Vehicle has been at dealership for a month and showing symptoms sporadically since the first few thousand miles getting increasingly worse over time. Reduced acceleration caus d many unsafe incidences when on the highway.

While driving my 2023 GMC Sierra 1500 Denali, 6.2-liter engine on the highway, the engine seized at 22,000 miles. GMC has been working on my truck since 9/7/24 and still no truck. The end state is, I was told by the Service Department that there is a design flaw with the 6.2-liter engine (something with the intakes valves being too large, resulting in the valve bending seizing the engine). I was also told, this dealer had two other trucks there now with the same seized engine. Their plan is to install a new engine with the same design flaw with the hopes it does not happen again. This was an extremely unsafe condition as I was travelling at 65 miles per hour on the highway when the engine seized, luckily, I was able to coast to a large shoulder after almost getting into an accident when it seized going uphill.

Engine goes to limp mode multiple times 3 of which happened getting onto the highway and almost creating an accident due to the reduced acceleration mode. CODe u0656 00 popped up each time. Dealer has yet to rectify due to lack of appointments… making me keep the vehicle saying it’s drivable but each time randomly goes into the reduced acceleration mode every restart.

In late February/early March, my GMC Sierra with around 9000 miles had the following to occur on a cold start: check engine light came on as well as the service esc light & traction control light, truck shuddered and shimmied. Took for service on March 4, 2024 with 9774 miles on odometer, where service tech said they couldn't duplicate concern (see attachments: March Service Invoice Pg 1 & 2). Took truck home & same issues kept occurring especially on cold mornings & days. Took the truck back for service on April 1, 2024 with 10895 miles on odometer. Told them to keep it till its fixed & to start it on cold mornings because thats when problem occurs. They had truck till April 12, 2024 and were able to duplicate the concern. Dealer changed the fuel injector (that was not the problem). Service tech finally found the cylinder 8 has a misfire until vehicle gets to operating temperature. They replaced all 8 lifters in bank 2 (right side) & gave me an oil change. This seems to have fixed the problem, but I won't really know until winter 2025. My problem with this lifter issue is that this engine will probably only last for 3 maybe 4 years tops because of all the metal shavings that are roaming around in the engine. This has been a problem with GM engines for some time & GM has yet to fix it or at least take responsibility for their poor engineering. I paid over $70,000 (of which GM made around $17,000) for this truck only to have the engine probably make it for a few years. My last truck I kept for 10 years. I don't see this happening with this truck.

The transmission failed as I as was turning on to a highway. It seemed like it was rapidly shifting between two gears, but I could not accelerate for several seconds and had to immediately pull over into the ditch to avoid a high speed collision. I took it to the shop the next day. The transmission valve body failed, which appears to be a common issue as I've researched incidents like this online. The part was on backorder. Once it arrived at the dealership, the replacement valve body immediately failed again. Now a 3rd valve body is on backorder with no ETA. I've been without my truck for over a month now with no end in site, and I do not have confidence that a 3rd replacement is going to provide a proper and long lasting fix.
