“VEHICLE BURNS OUT BLINKER BULBS AND HEADLIGHTS AT AN EXTREMELY ACCELERATED RATE: ONE A MONTH. ADDITIONALLY, THE WIRING HARNESS IS HEATED TO THE POINT OF BEING MELTED. THIS IS A FIRE HAZARD. I BELIEVE THIS MAY BE A VOLTAGE REGULATION OR GROUND ISSUE.”
Power train

“My vehicle speed up and slow down all that itself. It will not maintain speed even with my foot steady on the gas. It will not accelerate, but the major problem is my seatbelt gets stuck all the time I’m afraid to get buckled. I am unable to remove my seatbelt multiple times so now I have buckled my seatbelt behind me so I can start getting tickets. I’ve gotten like four tickets because I’m scared to be buckled that it’s not gonna come on down when I need it to be I’ve got 40 bought tickets. I was going about 20 mph when I went to the brakes for my vehicle accelerated by itself crashing into a pillar at the mall. I did call the police.”
