Reverse camera started to act up causing my camera to not be available while I am in reverse, this has also coincided with an error message stating "Service Electronic Throttle Control". My truck has experienced slow acceleration and the maximum speed is only 60 MPH. My stability control warning light is also on with the flashing "lightning bolt" and I can no longer use my cruise control.

There is a chronic problem with most Ram trucks, this issue isn't just related to one model of Ram trucks. The problem is when you go to fill-up your tank with gas, the fill neck continues to back up, which requires skill & a lot of patients just to fill your tank. And, this is also a major safety concern due to the high likely hood of an overflow of fuel & possible fire & explosion situation.

Truck def system error derates vehicle speed to 5mph in 85 miles. This is unacceptable as no dealerships are open on weekends or in the middle of nowhere. This EPA rule will get folks killed as folks driving 5mph on freeway towing a big trailer will get run into real quick.

The fuel take does not allow pressure to release causing a engine light and refilling problems. I can get about half a gallon in at the pumps at a time. This problem occurred randomly about 8 months after purchase of the new truck.
