Brakes lock up on vehicle while driving Must turn vehicle off and restart several times to disengage brakes. This has happened twice in the last 8 weeks, very concerning as we cannot use our travel trailer as we do not trust this not reoccurring.

Back in 7/2025, I was going to a Dr appt in Chandler, Az. When I arrived in Maricopa, Az, my truck stalled at the first stop light and would not start. I went over Kraegan Auto parts and bought a battery. After about 10 days, I was having to jump start my truck for the next few days. I took the battery back and they realized that it wasn’t the battery my truck called for. So, now I have the correct battery and everything working like it supposed to. In Nov 2025, my battery was starting to drain like overnight, and jump starting my truck every morning. I also told them, that the transmission was acting up. When I got on the highway my truck would be at 5000 rpm while doing 60 mph. I be would have to pull over to side of the highway, shut the engine down, and restart. Usually it would be good after the first time. So, up until now, I have no heater, no AC, my windows don’t go up or down, cruise control don’t work, l can’t move my power seat, so my wife has to put a pillow behind her and a pillow beneath her when she drives our truck. And I be still haven’t mentioned all be the little icons that are lit on the steering column. My truck is at the Jerry Seiner Casa Grande, Az. I have the protection plus coverage on my truck with GA Security, and I was told that because it’s a battery issue and found me at fault, they won’t cover me and I need to pick up my truck, because I can’t afford a $680.00 price tag. I’m on Medicare. That’s why I paid the $3500 for the protection plus coverage. So I guess it’s my fault or fault of my battery, my transmission doesn’t shift gears, power windows don’t work, heater or AC don’t work, can’t forget the cruise control. They said they are not covering nothing, to come get my truck.

Brake failure. I took the Truck to the dealer and was told not to drive it. The dealer ran two checks and then said brake failure. The rep had to leave, so another rep put my car in the shop overnight. The next day, I was told in writing that they could not find any problem. The code clearly showed brake failure. Date: [XXX]. Cost: $125.69. Mileage was 53,531. On [XXX], another brake failure. I went to an auto parts dealer (O Riley) in Topeka, KS, and they found a brake failure code(I have a copy). They told me to go to the dealer. I went to the dealer with a stiff pedal, which means driving is very unsafe. The dealer said too busy with oil changes and told me to return another day.
