I noticed lack of acceleration, then shortly after I realized my air wasn't cold. Turned air off and rolled down window. About to be rear ended as I was on the highway where speed limit is 70mph. My car was barely moving, I turned my hazards on. Kept looking at dash for messages, noticed water temp rising. No warning lights or anything. Crept slowly to destination off the highway, car jerked and sputtered, again barely moving engine light came on. I barley coasted into restaurant parking lot. Turned car off and called for help. My husband came looked at car, absolutely no coolant was in there. He added some we started the car, a cloud of white smoke came from the rear exhaust pipes we took a video turned it off and called for a tow. I took it straight to the dealer. They called in the morning saying they couldn't get it started and had to push it into the bay. I have yet to tell me a diagnostic hopefully I can update this same complaint. Car is 2022 with 35k so its under warranty.
