Re: Questions regarding ACC and stationary vehicles
My 2014 Grand Cherokee, built in April, has version one of ACC. Version 1 does not stop the vehicle. Last summer, Jeep switched to Bosch's new hardware, which does stop the vehicle. Each version has its own unique hardware and software.
I have found version one of ACC to be unreliable, even after upgraded software. Sometimes the EVIC displays "BRAKE!" for no apparent reason. At other times, especially in heavy traffic, ACC is silent.
