This truck is very unreliable. Seat belt retractor didn't work. Heater quit working also. Driving down road instruments say 0 MPH and I'm in reverse. Haven't duplicated that problem since it happened. Lots of noises under dashboard area possibly back of engine dept. Not from hitting bumps either. Dealer said problems fixed. NOT! Still there.
