I purchased my Vehicle a little over a year ago and have had multiple engine repairs. The first issue started with the lifters going out. Shortly after the lifters were repaired, the engine seized, causing us to get an engine replacement. A few days after having the new engine, we had the same knocking/ticking noise coming from the engine which was also repaired once again. Then yesterday, 3/13/25, the engine started to knock/tick once again, but this time more aggressively. (New engine had only 15,000 miles.)

I was driving home on the evening of Monday [XXX] in my 2021 Cadillac Escalade. The car began to shake, the yellow engine warning light began flashing, black smoke began pouring out of the exhaust pipes and there was a strong smell of fuel. I was 1/2 mile from my home. I limped the car home, left it in the driveway overnight, and called Cadillac Roadside assistance to have the car towed to the Cadillac dealership in Boulder, CO the next morning. The dealership's initial diagnosis it a failed lifter and cam. This is a known issue across all GM's 6.2L engines and is caused by their AFM/DFM management system. I am at 69,000 miles, with only 1,000 miles to go on the powertrain warranty (70k). GM needs to step up and recall these motors. They are saying that they might offer extended component coverage to someone that has had at least 2 failed lifter repairs. This does me no good with only 1,000 miles to go under my 70k powertrain warranty. There are many reports of completely failed engines from this problem on super low mileage vehicles.

I bought this car used and within a couple hundred miles the car would just shut off and the dash lights came on. I took it in and they diagnosed it and replaced the camshaft actuator. Within a few hundred more miles the same symptoms appeared as I was driving on a 70mph freeway. I had to pull over to the shoulder and this time noticed a metallic smell. Car would not turn on. Had to get it towed back to the dealer. After a month there they informed me the engine seized and needs to be replaced. Approximately 6 weeks and still no estimate to when I will get my car back.
