One problem related to noises during shifting has been reported for the 2018 Jeep Renegade. The most recently reported issues are listed below.
I bought this car new, this car is currently at 33596miles. Recently had noticed some really hard jerky shifting, so hard it feels like someone had bump into the rear of my car. When I start up the car cold, shift from park to reverse I can hear this harsh grinding, whining noise.
