NHTSA Complaint #11436451 — 2017 JEEP GRAND CHEROKEE

Hello, I was driving my 2018 jeep grand Cherokee about 2 months ago when out of no where the car turned off as I came to a hill , the radio volume increased all the way and I couldn't control it , the main break locked, the wheel locked and my shifter lock, I started to roll back down the hill and I had to use my e-break. the car acted like it was turned off but it just died , the radio never turned back down until the tow company did something. i took it to jeep and they were super unhelpful , they said it was a starter , so i paid 2000 to replace the starter to no avail. Now the AC/Heat goes on by itself or just doesn't work, the radio will go all the way up and i cant control it. however jeep in Englewood Colorado said there is nothing wrong with the car.. I think there is a safety issue with the start stop /eco mode. I think once the car turns off to save gas its not turning back on and there is no safe system. i have contracted jeep multiple times to no avail, the car has died on the highway 3 times now once while i was traveling 65 mph . I have paid for 6000 worth of fixes and its still happening.
