2021 Cadillac Escalade engine problems

“There is internal engine failure. Yes it is available for inspection. My safety as well as others were at risk when the engine started to fail, without warning, causing my car to jolt and briefly lose control of steering. If complete engine failure happened while driving, I would not have control over my car. My life and other's lives would severely be at risk. Car has been inspected and confirmed engine failure. Car is unable to be driven as we do not want to put anyone else at risk or make the problem worse. Car will be towed on Monday. There was absolutely no warning of this occurring. The symptoms first appeared while driving and the incident happened shortly after. There was a loud noise followed by my car being jerked traffic. I immediately pulled over until I could get my car safely home. When inspected the car was ticking with brief knocking noises. The ticking continued while the knocking noise became more abrupt and frequent.”

“The contact owns a 2021 Cadillac Escalade. The contact stated that while driving at 35 MPH, the vehicle completely stalled. The check engine warning light was flashing, and the Stability, Parking, and Collision warning lights were illuminated alongside several other unknown alerts. The vehicle was towed to a dealer, where two failed lifters were initially replaced. However, due to an abnormal sound, the vehicle was returned to the dealer, where the engine was replaced with a remanufactured engine. The manufacturer was notified of the failure by phone. The failure mileage was approximately 67,300.”

“My 2021 Cadillac Escalade ESV (VIN [XXX]) developed an engine failure after receiving the recall remedy for NHTSA recall 25V-274 (GM 6.2L V8 connecting rod/crankshaft defect). Symptoms: engine misfiring, dashboard warning lights illuminated, engine stalling/misfiring at idle, loss of power on acceleration, and a valve-like knocking noise coming from the engine. The loss of power and stalling while driving put my safety and the safety of others at risk. The vehicle is currently at the Vera Cruz Cadillac dealership, where it has been sitting for almost a month while awaiting the warranty process. The dealer has not confirmed the root cause. This engine failure occurred AFTER the 25V-274 recall remedy was completed on this vehicle.”

“Body of what was just sent to GM- this should answer most/all questions: To the GM Executive Resolution Team, I am escalating a critical safety hazard and severe dealer misconduct involving my 2021 Cadillac Escalade (53,700 miles), which is fully covered under the GM Factory Powertrain Warranty and a GM Platinum Extended Warranty. This vehicle is experiencing its third catastrophic top-end valvetrain failure. The component history on this VIN is as follows: First Failure: Lifters replaced at a GM dealership in Miami, FL. The worn camshaft was left in place. Second Failure: Lifters replaced at AutoNation Cadillac West Palm Beach. The worn camshaft was left in place. Third Failure: The engine is actively failing again, knocking and ticking severely on warm restarts due to complete bleed-down. My last attempt to address this issue was to take the vehicle to Wallace Cadillac in Stuart, FL, and physically presented the Service Manager with glitter-filled oil and an oil filter containing metal debris, proving advanced mechanical erosion and engine self-destruction. Instead of initiating a warranty claim, the Service Manager/Senior Technician at Wallace Cadillac…”

“I was driving down the interstate going 80 miles an hour and my engine completely shut off. I had to cross four lanes of traffic, on an interstate where the speed limit is 75 miles an hour, to get over on the shoulder while my car was able to accelerate. It was traumatizing and extremely dangerous and a miracle that a wreck was not caused. Engine would not start up after that.”

“On Saturday August 16, 2026, my family and I were in Laredo Texas and when we were driving on the freeway the motor blew out on my 2021 Cadillac escalade. One month before this occurred the dealership contacted me to replace the oil to a thicker oil because my trucks vin was on the recall and replacing the oil would help fix the issue. Replacing the oil did not fix this issue.”
