The trailer brake system has stopped working and displays the message "Service trailer Brakes" it does this no matter if several different tralers are hooked to the truck. These trialers test fine in other trucks and with meters. The trailer brake controller does not work. There are many owners reporting the same thing. It is a critical safety feature to stop the truck & trailer and probably already has led to some fatalities. Please issue a recall. Thank You.

Driving to work. Power steering went out and braking system seem to be ineffective. Instrument panel service light came on with the battery indicator displaying "battery charging system" fault.
