Engine Clicking And Tapping Noises problems of the 2011 Chrysler Town & Country

As we were driving at about 30 mph the van started to accelerate on its own. It revved up to 70 mph then to 50 then to 20 then back up to 70. We couldn't control the speed with gas pedal or the brake pedal. We were just gliding. I told my wife to put it into nuetral and tap on brake pedal till we finally slowed down. We then turned van off and let it sit. We then called are mechanics as we just had a transmission flush done. Of course they found nothing wrong with it because it wasn't doing it for them. We trust our mechanics as we have been using them for years now on all our vehicles and have never had a problem until this van. The next day we are sitting at a light and the van is jumping like it wants to go and a loud clunk noise happens like its shifting gears. Then the following morning my wife is getting in van to take kids to school and turns on van and it turns itself off. Our mechanics had this van for 2 days and have drove it with there computers hooked up to it and no red flags. The main mechanic says it's probably the computer. After further research on this van I now have found this is a very common problem with this make,model,year. Yet nothing has been done to resolve it. This is a major safety issue that apparently Chrysler is aware of but would rather make $1200 off consumers then fix on there own. Clearly my safety and my families safety isn't a concern for them. We drive almost an hour on the highway every other week. Now I have to be worried this van won't drive my family into another vehicle because its taking over and we have no way of stopping it.

Loud ticking noise from engine while engine is running.

We purchased this 2011 Chrysler town and country as a new vehicle in Jan. Of 2012. Since the purchase there have been 5 incidents where the van has lost all electrical power making clicking noises, and leaving us stranded. The final incident happened on Dec. 26,2014 while traveling in the mountains of north carolina. It was 10:30 pm, no street lights and nothing but steep terrain on the sides. The vehicle completely shut down and was making the clicking noises. The power steering was lost, headlights off and all other electrical functions were unavailable. Once in complete darkness we noticed we had shifted into the oncoming lane of traffic. We noticed headlights coming at us in the distance, luckily quick thinking and use of a flashlight we were able to warn the oncoming vehicle of our position in their lane. They stopped in front of our vehicle and turned on their hazards to provide warning for other vehicles. Being that we were in imminent danger, I had to disconnect the battery and let the system reset. After taking it to the dealership they once again said they could not find a problem. The dealership only stated, " have it towed in when it happens". Being that the last 2 times this happened we were left stranded in traffic, during late hours with absolutely no electrical power and my children in the car, it was impossible to wait to be towed in. They were unsafe situations that potentially had fatal results. I had to make the best decision at the time to protect my family. I am beyond frustrated with Chrysler for allowing me to leave the shop every time with no solution to the problem. My kids are afraid to get in van for fear of breaking down yet again. Five incidents with no resolution, no one knows how to fix the problem! a recurrent problem that can happen at any point- while on a highway or getting through a busy intersection.
