One problem related to starter has been reported for the 2015 Jeep Renegade. The most recently reported issues are listed below.
Salesman said they could make it like the one we wanted (we picked by color) but they would have to add remote start and heated seats. We picked it up noticing they butchered the seat putting in heated seats. We get home with it and shut it off mind you this is brand new, to wake up in the middle of the night cause I hear a car running in the garage its the Jeep. They tell me the remote start does it if battery is low. So I start parking it outside as not to die from carbon monoxide poisoning to find it outside running every night. At 1200 miles the rear end starts growling and transmission won't shift and it randomly shuts off going down the highway. Its the remote starter they say so they remove it. They gave it back to me with my money back. Does it again 3 more times and took it in 3 more times for shutting off on highway, rear end growling still and transmission not shifting. Get it back we couldn't find anything wrong with it but we did updates to the computer and transmission. Next day radio starts changing stations on its own as I record it with my phone, lights going off and on, windows not working and still not shifting. They replaced rear end pig, radio, wiring harness as they said the guy bent a pin installing remote starter. Then at 17,000 miles rear end and transmission start doing it again and the shorting comes back, new rear pinion at another dealership, new radio again as the other one shorted out, transmission still not shifting. Filed for lemon law Chrysler comes back with the car is fine its due to the after market equipment I had installed. Your dealer ship is who had it installed brand new vehicle. Still have problems with transmission not shifting or taking off when pushing gas pedal. Stuck with this junk cause they won't take it back. Called lawyers and they said love to help but that was a one and done deal. Never buy Chrysler again.
