NHTSA Complaint #11710043 — 2017 RAM 2500

I was pulling my gooseneck trailer with equipment on it and had to stop quick because car pulled out in front of me an when I pushed the brake pedal it was very hard to push an my exhaust brakes did not come on an I noticed check brakes light an anti trac light were both on.exhaust brake was turned on in full exhaust an exhaust light on dash showed it to be on but exhaust brakes did not start working so I had ended up leaving the highway an going through a ditch so I wouldn't hit the vehicle in front of me an hurting or killing someone or myself,luckily it wasn't a steep ditch so I was able to make it down to the service road down below without any injuries or damages to my truck or trailer or equipment, I've call several times once I recieved the recall notice about hydraulic brake problem on my truck an all they tell me is call back later no parts available to fix the recall problem, it's been a year now an still no parts,I haven't pulled my trailer since that happend and it's very inconvenient an costly not being comfortable about pulling trailer an not being able to stop,I very seldom drive the truck at all just to local store about a mile from the house,out in the country with none or little traffic, how long is ram going to be able to say no parts available, I think the government should tell them its been a year an you still haven't fixed the trucks they should have to buy them back an the higher average resale price or give us another truck.
