One problem related to cruise control has been reported for the 2013 Chrysler 300C. The most recently reported issues are listed below.
Adaptive cruise control works part of the time and will not work part of the time. The first few times it happened, it would start working after I turned the engine off and restarted it. Lately it will be off for several days and then work a few days before going off again. After checking the internet for solutions, I found none but found literally hundreds of people that have the same problem. I feel this is a safety problem because it causes unintentional speeding. In addition, the adaptive cruise control prevents the car from getting too close to the vehicle in front of you. After getting used to this feature, I find myself getting too close to other cars when the adaptive cruise control is not working. This is the situation when the vehicle is moving.
