Engine failed while driving down the highway at speed. Just shut off. Very dangerous. No power had to pull over. Vehicle would not start agin. Said low oil pressure. Had it towed to the dealership. Complete engine failure and had to have the motor replaced. After replacement engine still does not feel right and transmission acts up as well. Complete piece of junk for how expensive these vehicles are. Scary, dangerous and do not trust this vehicle anymore. Stuck with an unsafe piece of junk that's unreliable. Please help. New motor is exactly the same as the other one so it's going to fail again. It stays at the dealership instead of my driveway. People are getting screwed. Some kind of compensation needs to be done for us with these issues. Completely unfair.

While driving on a family road trip, our vehicle check engine light came in and put the vehicle in limp mode. This happened a couple of times but luckily we were close enough to our home we were able to make it home safely. The code received was indicative of a Coolant Control Valve Failure. In discussions with the dealer, there is currently a special coverage out for this component failing but that our VIN was not covered under this special coverage. After some research, we are not the only ones who are having this problem. I believe this issue is more wide spread than the dealer would like to admit. The special coverage is N252508341.

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.

I was driving my 2022 Cadillac Escalade when suddenly the engine shut off. Lost the ability to drive forward and steering became hard. I was close to being rear-ended as I was on the highway. Towed it to the dealer who said engine seized. Installed new engine after a month of waiting and the vehicle doesn't run right. It has a rough idle. Dealer installed incorrect oil as replacement engines were supposed to retain original oil of 0W-20. Had to make numerous trips to the dealer due to low coolant, wrong oil on a new engine and rough idle. Dealer says its fine. $100K vehicle with a rough idle is a joke!

Vehicle Make: Cadillac Vehicle Model: Escalade Model Year: 2022 Component(s) Affected: Engine, Fuel System, Powertrain, Vehicle Stability Control Incident Date: [Insert Date of Incident] Mileage at Time of Incident: [Insert Approximate Mileage] Summary of Complaint: While driving my 2022 Cadillac Escalade at approximately 70 mph on the highway, the vehicle suddenly lost all power and stability. This was due to an injector breaking off inside the engine, sending metal fragments into the camshaft, which subsequently locked the motor. This created an extremely dangerous situation as the vehicle became unresponsive and unstable at high speed. Just two days prior to this incident, the vehicle had been serviced by Quantrell Cadillac in Lexington, KY, where a recall repair involving the engine was performed. Despite that service, a catastrophic failure occurred almost immediately afterward. After the breakdown, Quantrell Cadillac attempted repairs over the course of three weeks. These repairs included replacing the injectors, camshaft, and other components, before eventually replacing the entire long block. However, upon picking up the vehicle, it is exhibiting the exact same failure symptoms again—making a popping noise, stalling the engine, and becoming unsafe to operate. This vehicle is clearly not safe to drive and poses a serious risk to myself, my passengers, and others on the road. There have already been multiple recalls related to this issue, indicating a broader systemic problem. We are requesting the NHTSA’s immediate assistance to investigate this safety issue and help us obtain a replacement vehicle that meets all applicable federal safety standards. This level of repeated engine failure & instability is completely unacceptable for any vehicle—especially one with such recent manufacturer service and recall repairs. When this stall occurs, the entire computer system & all safety features are shut down and collision avoidance is also disabled. Have viideo

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. ODI is opening this Engineering Analysis (EA) to further evaluate the scope and severity of the potential problem and to fully assess the potential safety-related issues of vehicles built outside the recall scope.
