My vehicle, a 2022 Cadillac Escalade with a 6.2L L87 engine, had the L87 recall completed withing the past year. The remedy was that it passed the inspection and engine oil was replaced with 10W-40 weight oil. Just yesterday 6/25/26, my engine quit working while driving on Interstate 265 in Louisville, Ky. Luckily, I was able to coast to the side of the highway where I stopped and was unable to restart the vehicle. After subsequent towing to the local Cadillac dealership, today 6/26/26, I was contacted by the service department that stated my engine needed to be replaced and would be covered under the L87 recall and under warranty.

The vehicle experienced a total engine failure on 03/16/2026 while traveling in the Houston/Friendswood, TX area going home from our vacation in Galveston, TX. The vehicle remained out of service at Big Star Cadillac in Friendswood until 04/27/2026. This failure is directly related to GM Safety Recall N252494000, involving defective internal engine components. Prior Ownership History (01/22/2024): The vehicle experienced an engine failure at 18,424 miles while under previous ownership. The engine was replaced by an authorized Cadillac dealership prior to my purchase. This material repair history was not disclosed at the time of sale. Second Failure (03/16/2026): At 47,503 miles, the replacement engine (N1240062M69X0196) failed catastrophically while in my possession during a return trip from vacation with my family of five. The failure occurred on Interstate 45, a heavily traveled highway, and we were barely able to exit the freeway. The new engine is part of the N126086N44X0534 series.

I purchased Used in Jan 2026 When starting the lifters were loud and I thought was normal engine operation. Since 2/17/2026 the engine vibrated or ran rough when idling. The auto/Stop Start feature failed randomly as the engine stalled when trying to start. The car passed the recall for the 6.2 Gm L85 engine issue, but is still having issues. The dealership Val Ward Ft Myers has the car now, and is replacing the lifters. My concern is that the Lower Engine issue was not properly diagnosed.

2022 Cadillac Escalade. Had the 6.2 liter engine recall done about 6K miles ago in which the engine was replaced. Now it’s back at the dealer again and needs another 6.2 liter engine. Been at the dealer for a month and GM has given them no update on when they can get another engine for it. This is insane. How am I ever supposed to be able to take my family around in this vehicle if the engines keep failing. Unfortunately I just bought this from the a dealer 6 months ago so I’m stuck with a vehicle that I do not trust… a $111,000 vehicle.

Purchased the vehicle 1 year ago and immediately it had oil consumption problems. Got low oil alarm after 2000 miles from the dealers oil change. Dealer told us it was within “specs”. 6 months ago we were told the 6.2 engine had a recall and a different type oil will be used. 1 month ago the engine locked up and it is now at the dealer waiting for an engine. Asked another car dealership about trading it in and they would not accept it as a trade-in because it currently has a stop sale issued. This means the vehicle is now worth nothing! Well, I have to hire Attorney to get anything for this vehicle? We paid $75,000 for it a year ago

While driving my 2021 Cadillac Escalade on an interstate highway at approximately 70 mph with my family, including two minor children, the vehicle suddenly and without warning lost propulsion, shut off, and shifted into neutral. This occurred in active traffic and created an immediate safety hazard. A warning message appeared instructing me to restart the vehicle. After several minutes navigating traffic, I was able to restart the vehicle briefly and exit the highway. Shortly thereafter, additional dashboard alerts appeared indicating critical engine and transmission failure. After exiting the highway, the vehicle shut down completely at a traffic signal and failed to restart. The vehicle was immobilized in an active roadway until police assistance arrived to prevent a rear‑end collision and a flatbed tow was arranged. The sudden loss of propulsion at highway speed placed vehicle occupants and surrounding motorists at serious risk. The vehicle is available for inspection and was diagnosed as having a seized engine on March 9, 2026, by Diamond Cadillac in [XXX] . This failure did not occur without warning. Prior to this incident, I repeatedly reported excessive oil consumption to the selling dealer, Otto Cadillac, from whom I purchased the vehicle in April 2025 as a Certified Pre-Owned vehicle. On two separate service visits, I reported oil consumption exceeding two quarts between recommended service intervals and requested that this be documented. I was advised that the consumption was “within tolerance” and was later informed—incorrectly—that this tolerance applied to my engine configuration. Otto Cadillac performed a recall-related inspection and implemented the manufacturer-directed remedy consisting of an oil cap replacement and a change in oil viscosity to SAE 40. No mechanical repair or deeper diagnostic action was taken. The subsequent engine seizure confirms that these mitigation measures did not resolve the underlying defect.

On March 19, 2026 around 830AM EST, the vehicle turned off while I was driving around ~40mph. I lost all power while on a busy street and I was unable to move the car to the side of the road. The car would not shift into drive or neutral, and therefore remained in the middle of the road until a tow truck had to flatbed it to the Cadillac dealership. The L87 recall on this vehicle was performed in August 2025, however the Cadillac dealership said there were no issues found with the L87 recall. The symptoms of today's issue - vehicle turning off while driving and does not start back up, is similar to other reports of this L87 recall and demonstrates that this recall was not accurately performed and/or remedied during the service.
