As I was exiting a highway offramp after about (4) hours of driving, the Infotainment radio went to full volume as I was listening to music either on Spotify (through Apple Car Play) or Sirius XM, I can't remember. It startled me to the point I almost rear-ended the car in front of me. As fast as I was trying to turn the volume down with the steering wheel controls, it went right up to 100% faster. The mute button on the dash did not work, I finally was able to hit the pause button on the app., and eventually fiddled with the infotainment system until the volume controls returned to normal.

On more than one occasion, the vehicle jolted forward when going to accelerate from being stopped at a red light. It felt like the vehicle was rear ended by a vehicle behind (it was not) to give some perspective.

On more than one occasion, the vehicle jolted forward when going to accelerate from being stopped at a red light. It felt like the vehicle was rear ended by a vehicle behind (it was not) to give some perspective. The last time it happened, the engine shut down but the dash stayed on, and the dash would not turn off, nor would the engine restart. The Chevrolet dealership which it was towed to is stating that the wires from the engine wire harness are chaffing and that the entire engine wire harness needs to be replaced. Additionally, there is a service bulletin posted by GM indicating that the proper repair for this is to replace the engine wire harness and add additional protection, which is a clear indication of faulty engineering to begin with.

I purchased this car on 7/15/24 and had no problems until 8/8/24 after I took my car through an automatic touchless car wash. Upon exiting the car wash, I noticed that the tailgate was now down even though I never unlocked it. I parked the car and closed the tailgate and began driving home. Halfway home, the tailgate opened again on its on. The bed was empty so I continued driving home and then closed it again. Later that night, I went out to take the garbage cans out to the street and again noticed the tailgate was down. I again closed it. The next morning, I went to go to work and the tailgate was again down. This would be a serious safety issue if I had items in the bed of my truck and the tailgate opened while driving. I searched this issue online and found that there are recalls for this exact issue in other trims of this truck but the recalls don't cover my trim. I took it to the dealer where I purchased it and they are looking into fixing it. I want you to know that this is an issue as well for this trim.

Hello, I was driving on the highway and all of a sudden the engine made a noise then the dash alerted me to shift into neutral/press start. I had to pull off the highway in single lane traffic and call for a tow. The truck was towed to the dealership. The truck lost power on the highway in single lane and there was no ability for other cars to go around me in a 75mph zone due to construction. The dealer diagnosis is that the motor is locked up and will require full replacement at only 70k miles. It is within years on powertrain but out due to mileage. There were no symptoms until the truck engine locked itself up.

On January 16, 2025, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE25001 after receiving complaints and field reports concerning engine failures in MY2019-2024 GM’s full-size truck and SUV T1XX platform equipped with the L87 6.2L V8 engine. These complainants alleged engine bearing failures resulting in knocking and growling noises from the engine’s bottom end and in some cases more severe consequences such as broken connecting rods leading to engine damage, or engine failure. If the engine fails during vehicle operation, the vehicle will lose propulsion, increasing the risk of a crash. On April 24, 2025, GM issued recall 25V-274 to address the concern with L87 engines produced between March 1, 2021, and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issues. GM’s recall remedy will be either an oil change to an oil with a different viscosity or engine replacement depending on the results of the remedy inspection procedure. To date, ODI has received 1,157 allegations of engine bearing failure. GM submitted 55,464 reports in total, with 29,752 unique VINs. ODI continues to receive allegations of L87 engine failures which fall outside of the scope of recall 25V-274. Based on GM’s recall, ODI will close this PE. NHTSA will continue to investigate complaints of engine failure outside the scope of recall 25V-274 as part ofEngineering Analysis (EA25007).
