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 ds 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.
