One problem related to automatic transmission cooler has been reported for the 2015 Jeep Renegade. The most recently reported issues are listed below.
In my driveway. I love behind my mom and when I stop to talk with while she is in the yard and leave my car running when I go to take off the emergency brake comes on and stops me. Going down the highway and stop at stop sign or red lights or just stuck in stop and go traffic when I go to take off the transmission either jerks real hard or makes the car feel like I have been hit from behind. Cooling fan has already been replaced when the vehicle wasn't 2 yrs old.
