On XXX, at approximately 6:30 AM, I was driving my Cadillac Escalade ESV when the vehicle suddenly and completely lost engine power while I was traveling on the roadway. The engine stopped without any warning.There were no warning lights, warning messages, unusual noises, or other indications that an engine failure was about to occur. The loss of propulsion was sudden and unexpected.I was barely able to maneuver approximately half of the vehicle onto the shoulder. A significant portion of the vehicle remained in the roadway, creating a serious safety hazard to me and other motorists. I was forced to remain in this dangerous position for approximately two hours while waiting for a tow truck.The vehicle was towed to Richland Motors in Roswell, New Mexico. The dealership diagnosed the engine as seized and determined that the engine requires replacement. I have been informed that a replacement engine is currently unavailable/on backorder, and I have not been provided with a definite date when the vehicle will be repaired.This incident is particularly concerning because the vehicle had already received the L87 engine recall repair at the dealership on XXX. The recall repair was completed approximately five months before this catastrophic engine failure. As part of the service performed at that time, the engine oil was changed to 0W-40.The vehicle subsequently experienced a complete engine failure and sudden loss of propulsion while being driven, despite having already undergone the recall repair. The most significant safety concern is the sudden loss of propulsion without any warning. There was no opportunity for me to recognize an impending engine failure and safely pull off the roadway before the engine stopped. I was fortunate to be able to get part of the vehicle onto the shoulder, but the vehicle remained partially in the roadway for approximately two hours while awaiting assistance.am requesting that NHTSA document and investigate this.

My wife's 2022 Cadillac Escalade was recalled for possible engine failure. The vehicle passed the recommended engine inspection procedure; new weight oil was installed, and I was assured that the Cadillac was safe to drive. Yesterday, while driving my family home from the children's playground, the engine failed as I was driving at the posted speed limit of 50 miles per hour. There was no warning of any kind, the engine just stopped working. I had to cross over the northbound lanes of traffic, with other vehicles, in theory, going the posted speed limit of 50 miles per hour, WITHOUT ENGINE POWER. While coasting the vehicle and my family to safety, I barely missing going down an embankment. The only reason there was not a crash is the fact that I was a professional driver and former driving instructor. This was a dangerous and potentially life-threatening situation and has to be investigated.

Engine knocking on cold start up. Second time hearing this. Loud “rattling” noise emanating from exhaust tips on rear of vehicle. I experienced this once before and notified my dealer. Additionally, at that time, I had a loss of power while towing a very, very, light empty trailer. The vehicle was struggling to maintain normal driving speeds and required considerable throttle input to do so. The loss of power was so pronounced that I actually pulled over to the side of the road in a parking lot to check to see if the wheel bearings had locked up on the small trailer I was towing. Of course, the trailer was completely normal and the hub temperatures were completely normal. I later found out about the GM L87 Engine issues and the recall issue. This vehicle then had the “pico“ test performed on it, and I was informed that it had passed. However, today I once again heard the same engine knock that I heard a few months ago.

After the recall work was performed, the vehicle began consuming engine oil at an abnormal and excessive rate between oil changes. Most concerning, during a recent check, the engine oil level was found to be extremely low, with no oil registering on the dipstick. This condition presents a significant risk of engine damage or failure and raises serious safety concerns. Prior to the recall service, the vehicle did not exhibit any abnormal oil consumption. The issue has only occurred after the recall was completed, which strongly suggests a direct connection to the repair.

On [03/23/2026], while traveling at 79 mph in high-speed highway traffic, my 2022 Cadillac Escalade suffered a sudden, total engine seizure and complete loss of propulsion. This catastrophic failure occurred without any prior warning lamps or symptoms. The loss of motive power at highway speeds created an immediate life-threatening situation, forcing me to navigate through traffic to the shoulder with no engine power. This vehicle is currently at [Parks Chevrolet Charlotte] awaiting a full teardown and is available for inspection. Critical Safety Concern: This engine seizure occurred AFTER Recall 25V-274 was marked "Completed" on June 18, 2025. This incident represents a direct failure of the recall remedy and is a documented escalation of the issues being investigated under NHTSA Recall Query RQ26001. I am reporting this to provide evidence that the current remedy is insufficient to prevent high-speed engine seizures and loss of propulsion.

On February 21, 2026, my 2022 Cadillac Escalade ESV experienced a sudden and complete engine seizure at highway speed at 57,825 miles just 8,613 miles after passing GM's PicoScope inspection under Safety Recall N252494000 (NHTSA Campaign 25V274). After fueling, I entered a highway on-ramp and accelerated to approximately 70 mph. Within 30 seconds, the engine lost power completely with no prior warning lights, no diagnostic trouble codes, and no audible warning. The only dashboard notification was a prompt to press the Start button. The vehicle behaved as if shifted into neutral, decelerating rapidly from 70 mph to 40 mph while I was navigating an exit merge ramp. I reached the right shoulder safely. Under normal weekday traffic, this failure on an active merge ramp could have caused a serious collision. The engine would not restart. The vehicle would not shift out of Park. OnStar could not remotely start the vehicle. A tow truck was dispatched; the operator could not shift the vehicle to neutral and required a dolly. The dealership confirmed the engine had seized and the engine would not crank. A complete engine replacement was performed under the recall warranty (RO 606490). The recall remedy was performed August 20, 2025 at 49,212 miles. GM records confirm the PicoScope result: "Engine Passed." The engine seized 8,613 miles later with no warning. This is consistent with 30-plus NHTSA complaints reporting loss of propulsion after the prior remedy, and demonstrates the inspection-based remedy is insufficient to identify engines at imminent risk of seizure.

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.
