Speed Control Springs problems of the 2013 Chrysler Town & Country

08/12/2017: I left my home & had only traveled a short distance & the entire vehicle stopped working. There was no power. The instrument panel was black & the engine was not running. I pulled to the side of the road as best I could with no power steering or brakes. I turned the key to off. I attempted to restart the vehicle. It took 3 tries to get it started. I did not drive it again until the next day. The problem did not occur again. It is now at the second dealership waiting for diagnosis. I also have an escalated case open with Chrysler customer service. 8/9/2017: I had to take my daughter to the doctor for an emergency appointment. I started the vehicle. Backed it down the driveway. Put it in park. The vehicle stopped working. The instrument panel went dark & the engine stopped. It took 8 tries to get it restarted. I did call & report the problem to the dealer. 8/3/2017: I took my vehicle into the dealer for the same problem. It was failing to start the day before. It took 3-4 tries. It also randomly shut itself off when I put it in park. Also once when I put it in drive. I reported this to the dealership upon dropping it off. They drove the vehicle 60 miles & could not replicate the problem. It never shut off while they drove it. They returned it to me but did note the error codes when they ran a diagnostic that the vehicle had had some type of failure. 7/11/2017: I had the vehicle at the dealership I purchased it used from a year prior. They diagnosed the failure to start & random power black-outs while driving as a screw being loose on the battery terminal. Charged me $200 to tighten a screw & sent me on my way. Spring 2017: contacted orig. Dealership. The vehicle was doing something odd. The instrument panel had gone black, the wipers were running at full speed & could not be shut off, yet the vehicle was still running. 08/10/engine light.
