At 53,000 miles the Coolant Control Valve has failed 2 times. A very common problem many owners have had. 1st CCV replaced at 45,000, second lasted less than 10,000 miles. Truck is forced into “reduced acceleration”. Part is on back order with no estimated ship date. Some owners are reporting wait times of 3 months or more. No loaner provided, was told truck is “safe to drive”. With reduced acceleration the truck struggles to get up to speed and has hard time maintaining even 65mph. It’s compounded when towing, making it near impossible to maintain pace with highway traffic. My vehicle is basically rendered useless as I use it regularly for highway commute and also towing. The vehicle may be “safe” in that it won’t blow up, but it’s certainly not safe to drive when it can’t maintain even the speed limit. If a quick acceleration is needed to avoid something it’s not capable of doing that.

I have had several check engine lights come on and the codes are for emission related issues. I made an appointment with the local chevy dealership to get the emission system looked at. However, the day before I was to take it in, I was driving and the truck dropped into "Low power mode" leaving me driving on the highway with no acceleration at all. I finally limp to the dealership only to tell me the valve body is shot and this has been a problem in these vehicles. They then tell me the parts are backordered and there is no ETA to fix. I start researching on the internet and this is a huge known issue and there should be a recall. Now I am stuck in a 10-year-old loaner with 130k miles. They know this is an issue, they should have a recall and the parts available.

I was driving my truck with my two young children in the back seat. I was accelerating to merge onto the interstate, and at 8th gear (around 74 MPH) I felt and heard a BANG and lost all propulsion, as if the transmission went into neutral. I revved several times and had no power to the wheels. I had to quickly check traffic behind me and find a place to stop on the side of a busy interstate, with two young children in the truck. While decelerating, I had no engine power and the transmission shifted from D to N to P while I was still moving - although it felt like it was still in N. As the truck decelerated, the engine shut off while in motion (around 30-40mph) and I came to a stop. As I was coming to a stop, I noticed I had a solid CEL/MIL along with several other warnings. I was unable to crank the truck - crank but no start - and unable to shift from P. Had I not been able to find a safe place to stop (e.g., in heavy traffic on the interstate or in city traffic) I surely would have been involved in an accident. When trying to tow the truck to the dealer, I had no way to get the truck out of P to load onto the tow truck flat bed. Subsequent attempts (at the Chevy dealer) to remove the truck from the tow truck flat bed were unsuccessful, as the truck would not shift from P nor crank. This was a severe safety issue which I am not sure is powertrain, electrical, or emission related but it could have ended in a severe crash on the interstate with my children. There were no indications of any sort of malfunction or issue except for when I immediately heard and felt the bang and lost propulsion on the interstate. I drove the truck earlier in the week without issue and there were no MIL's immediately prior to the incident. The truck is at Jimmy Gray Chevrolet, Southaven, MS awaiting evaluation and diagnosis.

On May 3, 2025 my truck would not go into reverse leaving me stranded 250 miles from my home. There was no indication the transmission was having problems (no warning lights and the truck was driving as designed). Then boom -- nothing. I was left stranded on a Saturday evening in a rough part of Detroit putting my safety at risk due to this sudden malfunction. The truck was taken to a GM dealer and had the transmission valve body replaced. Upon the repair, I drove the 250 miles back home. During this trip the torque convertor failed - again leaving the vehicle non operatable. The vehicle went back to the dealer and the torque convertor was replaced. About 1 week later the transmission valve body (that was originally replaced) failed again leaving the vehicle non operatable and me stranded again. I am now being told that transmission valve bodies are on national back order with no eta leaving me without transportation. Leaving a customer stranded multiple times despite replacing several major transmission components created a substantial safety risk to me and my family.

On January 16, 2026, the Office of Defects Investigation (ODI) opened Recall Query RQ26001. This investigation was opened to assess the remedy effectiveness of Recall 25V-274. ODI has received complaints alleging engine failure in vehicles after the recall remedy had been completed, whether that remedy involved an oil viscosity change or a complete engine replacement. General Motors (GM) issued Recall 25V-274 to address concerns of engine failure in the L87 engines produced between March 1, 2021 and May 31, 2024. GM cited the root cause as a supplier manufacturing and quality issue. GM’s recall remedy for Recall 25V-274 consisted of two different repairs, either an oil viscosity change or an engine replacement, based on the results of the remedy inspection procedure. ODI continues to receive reports of engine failures after the completion of the recall remedy. To date, ODI has received 499 complaints alleging post-remedy engine failure in vehicles subject to Recall 25V-274, 473 of which involved an oil viscosity change and 26 a complete engine replacement.

The Office of Defects Investigation (ODI) has received 1,157 reports of engine bearing failure failures in the L87 6.2L engine produced by General Motors (GM). Of the 1,157 reports received, 173 are outside of the scope of recall 25V-274. These engines are installed in Model Years (MY) 2019–2024 Chevrolet Silverado 1500 and GMC Sierra 1500, and 2021-2024MY Chevrolet Suburban and Tahoe, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV vehicles. The subject engine failures were investigated as part of a Preliminary Evaluation (PE25001). GM determined that these engine failures were due to multiple supplier manufacturing and quality issues. GM issued recall 25V-274 to address the supplier manufacturing and quality issues produced between March 1, 2021, and May 31, 2024. Based on the issuance of recall 25V-274, NHTSA has closed PE25001. ODI continues to receive a significant number of reports of engine failure in vehicles outside the scope of 25V-274. This presents a potential safety risk that warrants further investigation. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.

Status: closed (inferred from source dates) · Engine; Engine And Engine Cooling:engine:hard Parts Internal/mechanical
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.

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.
