Driving on highway, cruise control ser to 82, no cars in front. The car suddenly jolted twice, engine light and battery light comes, lost of power. Pulled over to shoulder in the middle of nowhere in Nevada. Tried to start the car, engine won't turn on, starter just kept cycling. Veh temp was just below 210 with a 1/4 tank of gas. Called dealership and service person asked is to use key to turn on car, no change and provided no other solution other than to take to dealership with the closest one being over 300 miles away. We decided to unhook and rebook the positive side of battery. Car restarted and currently driving it home as I write this complaint. 600 miles overdue for maintenance (by date due on July 26, 2021) and was scheduled upon return from trip which at the time should be approx 1000 miles over due.

Brought it in Nov 2020 regarding smells and engine issues as well as alignment. Neither were taken care of. Then March 2021, engine was leaking fluid and smoking, and the engine needed to be replaced at 20K. Did not provide a rental until later that week. After a month, I got my car back. After leaving the engine continued to smoke, brought it back. Gave no rental. Dealer said it was left over fluid from when they replaced it. Car is still having issues with the engine and smells. Under shield fell off and needed to be replaced twice.tire pressure was going off and brought it in twice for them to say they cant find where the slow leak is or why so they wouldn't fix it even though I have the Mazda insurance for tires.
