The brake pressure modulator valve leaks the transmission has problems and service airbags is on
Tire brand and size is cooper Discoverer stt 33×12.50R20LT. I was coming home on my lunch break and it blew out I didnt hit anything in the road or anything I have another tire the same brand and it started to separate on sidewall also but I felt a vibration so I took the tire off and put my other spare on and the vibration stopped.
Vehicle looses power and brakes go out then dies,doesn't matter speed. If slowing down and press the brakes, the locks, lights, and security goes crazy. This is dangerous as it is in intersections and caution for collision. The vehicle has to be off for a time frame and restarts fine and can go. Happened when coming from ramp and in middle of road with semi truck coming down by us.
Third brake line failure due to corrosion. Areas of failure are hidden from view above other components. Upon brake line failure, backup braking was inoperative in all cases. Vehicle was on a city street in motion attempting to stop. Brakes failed suddenly in all cases. Brakes were very noticibly inoperative before any indication on dash board. Pumping the pedal did nothing- the pedal went to the floor. Was told manufacturer no longer supplies brake lines for this vehicle.
It takes half an hour to fill my tank it keeps kicking off like it's full when it's not
I had jumped my dead battery and left the truck running. About 10 minutes after being jumped, the driver's airbag deployed. The vehicle never moved and was sitting idly in park and nothing touched the vehicle.
Clear coat peeling on all horizontal surfaces, upper dash panel developed multiple cracks creating a safety hazard if airbag deploys.
