Engine stopped running while driving. Took to the dealer. Engine was making a load grinding noise. Dealer replaced the engine. Drove home vehicle dripped oil in the driveway. Took vehicle to dealership. Engine block was cracked. Dealer replaced engine. Took vehicle to dealership for oil change . Engine had 1,800 Miles . Engine oil was contaminated with large pieces of metal. I took the used oil filter home cut it open and filter was full of metal as well. Took back to dealership and ask to replace the failing engine and was denied by the regional service manager as well as the general motors engineer. Their answer was if the engine fails AGAIN the vehicle is under warranty. The engine oil continues to be full of metal chunks. In my opinion metal in oil is engine failure. This vehicle is unsafe to drive with the engine full of metal.

On Sunday, September 14, 2025, while driving northbound on the Palisades Parkway at approximately 11:30 PM, the vehicle suddenly lost all propulsion without any prior warning. I was traveling around 45– 50 mph when the dashboard lights began flashing, and the vehicle shut down completely in active highway traffic. All systems—including power and acceleration—dropped instantly. I was unable to maintain speed and was not even able to brake, and had to fight to steer the vehicle safely onto the shoulder as it slowed down. There were no warning lamps, messages, or irregular behavior prior to the failure. The shutdown occurred instantly and without cause, creating an extremely dangerous situation on a dark highway late at night.

On Wednesday, September 3, 2025, while driving in regular city traffic, the vehicle suddenly lost propulsion without any warning or dashboard alerts. There were no warning lights, messages, or abnormal sounds before the failure occurred. The vehicle instantly shut down while in motion, causing a total loss of acceleration power and leaving me stranded in the middle of traffic. This occurred the second time I was driving the car after prior service, and the vehicle again stopped completely, forcing me to pull over and contact OnStar roadside assistance. This was the second major propulsion failure in a short period, each time occurring unexpectedly while driving. The repeated sudden shutdowns without warning present a serious safety risk and indicate an unresolved defect in the vehicle’s electrical and propulsion systems.

On Friday, September 5, 2025, while driving with my family, the vehicle suddenly stalled while in motion. There were no warning lights or error messages before the failure occurred. While traveling at normal road speed, the vehicle instantly lost propulsion, steering assist, and braking power, leaving me without control in live traffic. For several seconds I was unable to steer or slow down normally — it was an extremely dangerous situation. The vehicle briefly restarted twice, then completely died and could not restart again. I had to pull over to the shoulder and call for assistance. This repeated sudden loss of power while driving, without any prior warning lamps or messages, creates a severe risk of collision or injury to occupants and others on the road. The vehicle’s unpredictable failure to maintain propulsion or braking control is unsafe and unacceptable.

While driving about 60–65 mph westbound on NY Route 17 near Exit 125, a warning message appeared on the dashboard reading “Restart Engine.” Within seconds the vehicle lost all propulsion, steering assist, and braking power. Pressing the accelerator did nothing and the car began rapidly decelerating in live highway traffic at night. I struggled to steer into the shoulder with great effort because the steering and brakes had become extremely heavy. Once stopped, the engine would not restart — there was no crank and no response when pressing the start button. The vehicle was later towed to the dealership for inspection. This failure occurred without any prior warning other than the single “Restart Engine” message that flashed moments before the loss of power. There were no check-engine lights, alerts, or performance issues beforehand. Unity Chevrolet Cadillac confirmed that the engine had seized and replaced the entire engine assembly, starter, and battery under warranty. The vehicle remained out of service from August 7 to August 22 2025. This sudden failure created a severe safety hazard — a complete loss of propulsion, steering assist, and braking at highway speed could easily have resulted in a high-speed collision.

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.
