Engine stopped running while driving without any prior notifications, lights, or warnings. Car was stationary in the roadway while my wife tried repeatedly to restart the engine. After several tries the engine started and ran long enough to pull car off roadway. Car was inspected last year and procedures per recall notice where performed and was then deemed safe and reliable. Recall corrections did not fix the problem.

I was driving and the highway speed was about 55 mph and suddenly the car shut off and I was in a very dangerous spot

VIN [XXX] I did the engine recall. All documented in Braman Cadillac. After the dealer gave me the clear after recall check, they did the GM change of oil etc. But i recently had an afrer recall failure with knock sounds coming from the engine. It is on 3 videos I saved, conditions were while iddle, while driving, while accelerating and braking. so vehicle motionless still had the sound. I had loss of power a few months ago, that I didn't associate to this recall until this sounds that I couldn't reproduce when took the car in, but it is on video. At this point I want my engine replaced and I need help with it as the solutions given from dealership are insuficient given the scope of problem. the car obly has 37k miles INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

2023 Cadillac Escalade Sport Platinum with 6.2L L87 V8 suffered catastrophic engine failure on 6/20/2026 at approximately 38,658 miles. Vehicle had GM recall N252494000 performed at Coulter Cadillac in Phoenix, AZ on 12/3/2025. Engine reportedly passed GM recall inspection and received oil-related remedy rather than engine replacement. Approximately six months later, while driving on I-17 near Black Canyon City, AZ at highway speed on a 75 mph interstate, the engine suddenly shut down with no warning signs or alerts. Vehicle shifted to neutral and lost all propulsion. There were no prior check-engine lights, oil-pressure warnings, reduced-power warnings, abnormal noises, or other alerts before failure. I was traveling with my family of four plus our dog in approximately 105°F heat at the start of a road trip. I was able to maneuver to the shoulder, but the sudden loss of propulsion at highway speed created a serious safety risk. We were stranded roadside for nearly one hour in a remote area. Earnhardt Cadillac in Scottsdale, AZ diagnosed crank bearing failure. GM/Cadillac has indicated the proposed repair is installation of a refurbished/remanufactured replacement engine. I am concerned this failure occurred after the recall remedy had already been completed and appears consistent with the L87 crankshaft/connecting rod/bearing failures and post-remedy failures under NHTSA review. Cadillac case number is 103635161.

We were driving on an interstate in Indiana and the car jerked and then automatically went into neutral. We couldn’t accelerate or put the car back into drive. We had to get over 2 lanes and onto the shoulder. We were able to put the car in park once on the shoulder but the car would not turn on or off. We couldn’t do anything. All electronics were still running but the engine was not running. The emergency break went on as well. The car sat on the side of the road for 3 hours with the electronics going while waiting for a tow which then wore out the battery. Because the car switched on the emergency break, the towing company had a difficult time getting it up on the tow truck. There were no warning lights going off. We were going 75mph on a highway with my children in the car! Scariest thing ever. I can only imagine what could have happened. We were so lucky to not be hit on the highway trying to change lanes and not being able to accelerate. Then we had to sit on the side of a highway for 3 hours in 95 degree weather and we were 2.5 hours from home! After 3 hours, a tow truck finally showed up. My family had to take a taxi to the nearest dealership because the tow truck would not take us. After 4 days, the dealership finally ran the diagnostic test and said the engine had seized up and we need a new engine which is on backorder. That dealership is 2.5 hours from home, so we then had to pay for another tow truck to get my vehicle back up to home so the local dealership could work on it. It has been one week since this incident happened and we have no idea how long the repairs will take but it’s my understanding that they are just replacing the faulty engine with another faulty engine because GM has no fix for this engine failure issue so it will happen again!!!
