I purchased a used 2022 Cadillac Escalade. With 34,000 miles…as I was driving in the highway the engine failed. No brakes, everything went black on the screen and engine was out. Dealership told me it was harness chaffing and fixed it. No less than a week later, on the highway, the engine seized and failed. New engine is being ordered. This was extremely dangerous at high speeds and almost killed us, twice.
