Example complaints

Brakes: “Rear brakes started dragging while driving along. I stopped to check them and the right rear brake was very hot and smelling of overheated brakes. I turned around to try and make it home but the next time I applied the brakes, the brake pedal went to the floor and I had to use the emergency brake to get stopped. I was towed to a Freightliner service center where they told me I had a stuck caliper. This vehicle is a motorhome conversion by dynamax and has hydraulic, ABS brakes.”

Engine cooling: “The contact stated while traveling 60 MPH, the engine stalled without warning. The vehicle coasted to the side of the road and the dealer was contacted who suggested the fuel filter be replaced.

The vehicle stalled again and would not restart. The vehicle was towed to a dealership, and the oil pump, injectors, turbo, and radiator filters were replaced but the problem persisted. …”
