NHTSA Complaint #11637899 — 2023 CADILLAC ESCALADE

I was driving my 2024 Escalade on the interstate at 80 mph when the vehicle started jolting and acting as if it was going to stop. My speed dropped from 80 to 55 while the screen started flashing "press start button", all while the vehicle was still running. Luckily I was able to cross 4 lanes of traffic and pull over on the shoulder. I was fortunate that I was not hit. I turned off the vehicle and then started it back up. Two days later, the vehicle was once again acting as if it didn't want to start/go. After a 40 minute trip, the vehicle died as I pulled into my driveway. It did start back up but the engine was making horrible sounds. I had to be towed to the dealership. I had no warning lamps prior to the flashing "press start button". The problem has been confirmed by the dealership. Engine failure. I need a completely new engine. This will soon be 8 weeks ago that my vehicle was towed. I have been in a rental since that day. The dealership says they have no updates as to when the engine will arrive. After tests done at the dealership, they did confirm that the problems were happening on longer trips. Most of my driving is around town, hence why I noticed the problems when I had been driving for 30 plus minutes.
