I was driving at highway speeds when my vehicle suddenly lost power and began rapidly decelerating. The vehicle eventually stalled in the middle of the roadway, creating a serious safety hazard for me and other drivers and significantly increasing the risk of a crash. This vehicle had previously undergone the GM safety recall inspection under Recall N252494000 for the L87 6.2L engine loss of propulsion defect. The recall inspection and remedy failed to identify the underlying engine defect, and the engine still catastrophically failed only months later. After the recall was completed, the vehicle was maintained according to GM’s updated recall instructions, including use of the required 0W-40 engine oil. Despite compliance with the recall remedy and maintenance requirements, the engine still failed during normal highway operation. The recall specifically acknowledged potential manufacturing defects involving the connecting rod and/or crankshaft components that could lead to engine failure and loss of propulsion. That is exactly what occurred in this incident. I believe the recall inspection procedure was inadequate and failed to detect defective engines that remain unsafe and subject to catastrophic failure even after being marked as “recall completed.”

5/7/2026: Travelling on freeway with son at 70-75mph, vehicle shifted itself into Neutral causing loss of acceleration and a message stating vehicle engine needed to be restarted. I had to navigate crossing multiple lanes of traffic to safely exit while quickly loosing speed. Was able to safely exit the freeway and come to a complete stop to restart the engine and resume normal driving. 10 minutes later, the vehicle repeated this causing yet another safety issues. Vehicle has been at the dealership since 5/8 and as of this report 5/12, the technicians are reporting that they have not been able to replicate the problem. I am in fear of the safety of myself and my family and am very hesitant about accepting the vehicle back without a proper diagnosis or repair.

I am filing a safety complaint regarding repeated engine and drivability issues with my vehicle, which began shortly after purchase and have continued despite service visits. I purchased the vehicle on 03/04/2023. Within approximately one month (03/26/2023), I began experiencing abnormal engine behavior, including ticking noises and instances where the vehicle would shut off and require restarting. I immediately brought the vehicle to the dealership. At that time, the issue was not properly diagnosed and I was told after a test drive that the noise was “normal. On 12/18/2025, I was later notified of an engine recall involving the same type of engine problem I had been reporting since 2023. I brought the vehicle in 12/19/2026 and the engine failed 3 times. I was informed that an engine replacement was necessary, and the vehicle was left at the dealership. It was ready for pickup on 01/14/2026 after the engine replacement was completed. On 04/15/2026, the vehicle began making knocking noises and would not shift into drive or reverse. I had to turn the vehicle off and restart it in order to regain drivability. On 04/16/2026, while driving, the vehicle began making a loud revving noise without accelerating and started to slow down and lose power. I was forced to pull over to the side of the road. The vehicle would not respond properly until I turned it off and restarted it again in order to continue driving. These ongoing issues present a serious safety concern due to repeated loss of power and drivability while operating the vehicle.

The contact owns a 2023 Cadillac Escalade. The contact stated that while driving 69 MPH with the cruise control set, the vehicle started driving sluggishly and failed to maintain the set speed. The vehicle unintendedly decelerated to 62 MPH. The ‘High Oil Temperature” warning light illuminated, and the vehicle decelerated unintendedly to 55 MPH. The vehicle then lost automotive power, stalled, and shut off unexpectedly. The vehicle was towed to a dealer and was diagnosed with complete engine failure. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 60,400.

Dealership stated they fixed recall ref# N252494000 on 9/24/25. But on 4/9/26 noticed engine noise (knocking), then a lose of power and then vehicle stalled on the highway.
