Bought a 2021 Escalade and at 50,000 miles it turned off at the middle of intersection while riding with my kids taking them to basketball. I had it towed to Cadillac they said it needed a new battery I left with new battery and broke down on the interstate while trying to pick up kids from school. I then had the car towed back to shop where they then said two days later I needed a new motor and that my warranty would not cover that and I’d have to pay 25,000-30….even though I just bought the car for 100,000….i towed it to RK Chevrolet where I waited for Over a YEAR. I had to buy a used car because I was never offered or able to use a loaner. My Cadilliac then got hit at the shop by a uber driver and the whole front in had to be fixed. I got my car back in November 2025 it’s now August 2026 9 months later it is back in the shop for motor and transmission issues with check engine light on. I am a hard working mother and I have spent more money on a car in my life. As a mother with kids to not have a car is a problem but the worst is the lack of help I have received. I would love any help in what I should do as this has been a nightmare. Please send or give me any advice I would greatly appreciate it.

Following a recent oil change, I started the vehicle back up to drive approximately an hour to another city and the engine was making a horrible “knocking” sound. Took the vehicle back to the dealership and it was confirmed catastrophic engine failure which fell under GM’s known 6.2L engine issues. My safety and my children’s safety were put at risk because had I not drove directly to the dealership instead of getting on the highway as planned, the vehicle could have died at highway speeds posing a serious safety risk. No warning signs, no engine light, nothing prior to the failure.

GM issued a special coverage in bulletin N252508341 for the coolant control valve in my vehicle. This issue happened to my vehicle exactly as the symptoms are stated in the bulletin: check engine light, P1098 code, fan running at high speed with the engine on and off, and reduced acceleration. I took the vehicle to the dealer to be covered, and they say my vehicle is not covered by the bulletin. To be clear, the bulletin covers 2021-2023 Cadillac Escalades with the LM2 3.0L Duramax engine. My vehicle is a 2021 Cadillac Escalade with a LM2 3.0L Duramax engine. Which had all the issues and symptoms listed in the special coverage. Yet, they say it is not covered. This seems incredibly shady. And very wrong. Why in the world would they not be covering my vehicle? It seems unsafe to be driving a vehicle that has reduced acceleration, a fan constantly running at high speed, and a check engine light for malfunctioning parts. Faulty parts from GM which they have already acknowledged are bad.

While driving my 2021 Cadillac Escalade to Utah, the engine completely locked up and failed without warning. The vehicle had to be towed to a GM-authorized dealership. Upon inspection, the dealership confirmed the failure was directly related to an active safety recall on the vehicle. Prior to the failure, there were no check engine lights or no other warning lamps, messages, or symptoms. The failure occurred suddenly and without additional notice. The dealership stated the needed part is currently on national backorder and that the vehicle cannot be repaired or safely driven until the part arrives. It has now been over four months since the vehicle was brought in, and there is still no estimated repair date from GM. This has left me without a functioning vehicle due to a known safety defect. The vehicle remains inoperable at the dealership.

Vehicle was towed to a dealership where upon inspection they found the rocker arm for the intake valve on cylinder 6 not moving, a bent pushrod, and a lifter that had come apart. It is unknown if an inspection was performed by the dealer beyond the initial diagnostic. The check engine light had come on within the last 12 hours. We called onstar and they said the code indicated we should bring the car to the dealer within the next 24 hours. There was no indication that it was unsafe to drive with the light on.

1st incident - Car stalled at a red light and had to be towed for repair. It was determined to be the fuel injector pump. No lights came on and there was no indication of an issue prior to it stalling. 2nd incident - On the intestate it started making a rattling noise and felt like it was losing power. No lights came on to indicate any issue. Luckily we were able to exit the interstate but it stalled on the middle of the exit ramp. We were 5 hours away from home and it was towed to the nearest Cadillac dealership. They had the car for approximately 2 months and replaced the engine. 3rd incident - the car was back 2 weeks from the engine replacement. For 1 of these weeks it sat in the airport garage. When it was turned back on after sitting for a week the check engine light came on. I was able to make it home from the airport but it stalled out in our driveway and had to be towed again. It was determined it was the fuel injector pump and it was replaced again. The pump was only about a year old.
