2023 GMC SIERRA 1500 Complaints

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.

Subject: Safety Complaint Regarding Steering Airbag Trim and Steering Axle Issues Dear National Highway Traffic Safety Administration (NHTSA), I am writing to formally file a complaint regarding serious safety issues with my GMC vehicle. Specifically: 1.The steering airbag trim has begun to crack, which raises concerns about its structural integrity and potential interference with airbag deployment in the event of a collision. 2.The steering axle is making unusual noises due to loose bolts and worn bushings, posing a potential risk to steering control and overall vehicle safety. I recently took the vehicle to an authorized GMC dealership for inspection and repair. However, the dealership refused to address these issues despite their clear impact on safety and their apparent connection to manufacturing defects. Given the critical nature of these problems, I urge the National Highway Traffic Safety Administration (NHTSA) to investigate this matter thoroughly. These defects not only compromise the safety of the vehicle but also endanger the lives of the driver, passengers, and others on the road. Thank you for your attention to this matter. I am happy to provide any additional information or documentation required for your investigation.

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.
