After accelerating from a stop sign to about 60mph on a 2 lane road, the engine shut off and the vehicle changed to neutral. I had to glide the truck down the road and off to the side. Vehicle would not start and had to be towed to a Cadillac dealership on a flatbed.

The contact owns a 2024 Cadillac Escalade ESV. The contact stated that while attempting to start the vehicle, there was an abnormal ticking sound coming from the engine. The vehicle was taken to the dealer where it was diagnosed and determined that the engine needed to replaced. The vehicle was not repaired. The VIN was not included in NHTSA Campaign Number: 25V274000 (ENGINE and ENGINE COOLING). The manufacturer was not notified of the failure. The failure mileage was 20,000.

I own a 2024 Cadillac Escalade ESV equipped with GM's 6.2L L87 V8 engine. The recall remedy for GM Safety Recall N252494000 (NHTSA Campaign No. 25V-274) was completed on April 17, 2026, at approximately 48,905 miles. Only approximately 2,347 miles later, on June 15, 2026, at approximately 51,252 miles, the engine experienced a severe malfunction while I was driving with passengers. Without warning, the engine began running extremely rough with severe vibration and shaking. The Check Engine Light began flashing, and Service StabiliTrak and Service Traction Control warnings appeared. A few minutes after I stopped the engine, it would not restart. I found no measurable engine oil on the dipstick. When the engine was started again, a large amount of blue smoke was emitted from the exhaust, while the engine continued running extremely rough. GM's official MyCadillac application displayed critical warnings for the Engine & Transmission System, Emissions System, Transmission System, and Variable Valve Timing (VVT) System. GM ultimately determined that the engine required complete replacement under warranty. Despite completion of GM Safety Recall N252494000 (NHTSA Campaign No. 25V-274), the engine required complete replacement only approximately 2,347 miles later. The replacement engine remains on backorder. I understand that NHTSA has opened Recall Query RQ26001 regarding post-remedy L87 engine failures. Because my vehicle experienced a post-remedy engine failure only approximately 2,347 miles after completion of the recall repair, I respectfully request that this complaint be included as part of Recall Query RQ26001. I have preserved photographs, videos, diagnostic screenshots, and repair records.

On June 14, 2026, while driving approximately 70 mph on a Michigan freeway, the 6.2L V8 engine began shaking violently. The vehicle lost oil pressure, warning messages appeared on the dashboard, and the vehicle completely lost propulsion and shut down while still in motion. My spouse and child were inside the vehicle. The sudden loss of power at highway speed created a serious risk of a collision, although I was able to bring the vehicle to safety. No collision, bodily injury, fire, or property damage occurred during this incident. An OnStar/Cadillac notification reported a critical engine and transmission system problem and diagnostic trouble code P0016. The vehicle was towed directly to an authorized Cadillac dealership. The dealership opened the repair order on June 15, 2026, at approximately 46,640 miles. The dealership determined that the vehicle required a replacement engine. The replacement engine later arrived, but additional required parts, including a seal kit and gasket, were still outstanding. General Motors advised in writing that there was no estimated arrival date for those parts and no confirmed repair-completion date. The vehicle and failed engine components have been in the possession of the authorized Cadillac dealership and should be available for inspection. General Motors confirmed that the engine failure and repairs are covered under warranty. I am reporting this incident because the engine failure caused a complete and unexpected loss of propulsion at highway speed, placing the vehicle occupants and surrounding motorists at risk.

Driving on the freeway at 70mph, vehicle lost power and slowed down with no warning. Gas pedal unresponsive. Received message on screen to start vehicle. was able to swerve to shoulder lane out of oncoming traffic's way just in time for it to come to a full stop and never start again. When attempted to start vehicle again, it was completely unresponsive. Had to call for police escort since car was in near path of oncoming traffic. Tow truck had to haul to dealership location near home (100+ miles away). Currently still receiving alerts from onstar that all vehicle functions are clear and OK with no issues "green checkmark" on all components. No recalls or service issues in the vehicle for 22k miles until failure.
