2023 Cadillac Escalade: engine stalls while driving

Filed Oct 19, 2026 · Engine · LA

I am reporting a catastrophic engine failure on my 2023 Cadillac Escalade with the 6.2L L87 V8 engine (currently at 106,000 miles). The engine suffered sudden engine failure while driving / stalling, creating an immediate traffic hazard. The vehicle was towed to an authorized Cadillac dealership in Louisiana, where it has remained completely unrepaired for 60 consecutive days. The dealership claims they cannot repair the safety defect because they are "short-staffed." This vehicle’s failure directly matches the systemic manufacturing defects currently under investigation by the Office of Defects Investigation in Engineering Analysis EA26005. The manufacturer's inability to provide a timely repair through its dealer network leaves a known safety hazard unresolved.

On 06/23/2026 at approximately 62,745 miles, I brought my 2023 Cadillac Escalade Sport Platinum 4WD equipped with the 6.2L L87 V8 engine to a Cadillac dealership because of excessive engine oil consumption. The vehicle has been consuming approximately 3 quarts of engine oil every 2,000 miles, or roughly 1 quart every 650-700 miles. The dealership began an oil-consumption test to document the condition, and the vehicle is currently still at the dealership undergoing evaluation. This vehicle is equipped with the 6.2L L87 engine involved in the federal safety agency Safety Recall 25V‑274 / GM Recall N252494000 concerning internal engine damage and possible loss of propulsion. I do not know whether the excessive oil consumption is directly related to the recall defect, but I am concerned that this level of oil consumption may indicate an internal engine problem that could lead to inadequate lubrication, engine damage, stalling, seizure, or sudden loss of propulsion. The vehicle is available for inspection at the Cadillac dealership. The dealer has service records and oil-consumption-test documentation associated with this condition. I am filing this complaint so the excessive oil consumption on this L87-equipped vehicle is formally documented with the federal safety agency and can be considered along with other reported L87 engine concerns.

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.”

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.

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.

My wife was driving this vehicle home after dropping off kids at school when the engine suddenly stalled in the middle of the road. Luckily no one was directly behind her or she would have been in a collision. After being towed to the dealership, they informed us the engine "failed". There was no check engine light or warning message prior to the engine suffering sudden and catastrophic failure. Vehicle has less than 28k miles. The car is currently at the dealer with no time frame for repair because the engine is on "back-order".
