I own a 2018 Jeep Compass. My car has been stalling and going dead when stopping at stop signs/lights, when slowing to turn, and when entering on-ramps to a highway. Other issues that have occurred simultaneously (but not necessarily all at once) include, start/stop not working, the parking brake engaging when stopping, sound system unavailable message (despite that the radio works properly) and the car ds not restart immediately when hitting ignition. These issues have been ongoing for approximately one month. The problem initially started with the parking brake engaging when coming to a stop. In order to disengage the brake, the car had to be turned off and then back on again. Then the car started to stall when slowing and stopping. In the latest occurrence, my car stalled 3 separate times within a 10 mile drive. On the 3rd stall, we were turning left to enter the highway when the car stalled suddenly. The car behind us had to slam on their brakes and swerve to miss hitting us. We took our car to the dealership on December 17th. At that time they replaced the cars main battery, but audio system unavailable message remained on, to which the service advisor said we should probably replace the radio, despite that the radio is functioning properly. We took the car with us December 18th. In less than 48 hours the car was stalling at almost every stop again. We returned the car to our dealership on December 26th, where it remains as of January 1. The dealership said, via phone, they have been unable to pinpoint the problem, at this time. It is extremely dangerous for a car to stall when it should otherwise be in motion. This puts myself, my son, our passengers and those around us in danger. This is an issue that warrants immediate attention and we welcome an inspection if someone could just identify the problem and fix it before someone is hurt.
