“On multiple occasion the dash controls will freeze buttons will not work and touch screen will not work I took it in to the dealer and they told me that nothing is wrong with the vehicle. But every now and again it will freeze up the only way to get the control to work again is to pull over and turn the vehicle off and on.”
NHTSA complaint #11267838, filed 2019-10, 1 miles“Happened 3 time now. Each time I was driving slowly, idling along, in parking lot. Each time I was in gear (drive) moving at idling speed e.g. Parking lot crawl. All electrical shuts off just like I had turned the key off. All lights off, AC off, radio off, engine off, everything off. No warning lights, nothing - just turns off. Vehicle restarts fine with no immediate recurrence. For some reason it simple turns itself off. It's going to be bad if this happens when pulling out into traffic.”
NHTSA complaint #11341534, filed 2020-07, 19,500 miles“This started about 3 months after I got the truck and has been doing it since. On three separate occasions, truck engine shut off after stopping then turning right on city and neighborhood streets. First time I pulled out on a road where the speed limit is 55 so I was lucky no one was behind me when the engine cut out. On the fourth occasion, truck shut off after backing up from parking spot and pushing on gas to go forward. No check engine lights, no noises or vibrations to tell me truck is going to shut off. I have to look at dash to see if it has gone black. …”
