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.
2014 Jeep Grand Cherokee Overland 3.6L 4x4; Quadra-Lift II; Off-Road Adventure II; Advanced Technology Group; Vesuvio Indigo Blue interior; white exterior; engine block heater; CD Player. Built April 2013. As of June 24, 2015, the Jeep has been driven about 43,000 miles (70 000 km). The transmission failed at 41,000 miles (65 000 km). A Jeep dealer under warranty replaced the transmission's valve body assembly. At 43,000 miles (70 000 km) the valve body assembly failed for a second time.
