Engine The engine shut off at 70mph with no warning and I lost complete power. I had a tractor trailer behind me and one on my left side no power I was nearly killed . Rotolo Chevolet replaced the 6.2L V8 engine Vehicle was inspected by Rotolo Chevolet and they said it was engine failure There was no warning that the Escalade would just shut off at a high rate of speed. It completely just lost power. I only had 85,000 miles on the Escalade. I had taken it to Rotolo Chevolet because I had all the tires changed. While diagnosing my problems with tires they told me of the engine making noise. I had them change the oil but they said it needed a engine. I had no idea this would happen. Ds GM want to rob their customers so badly that they would jeopardize their life for GREED. I think the Escalade cost enough.
