Trac light would come on and off a few times. Eventually the trac off, and abs light stay on. It occurs at random moments while stationary and in motion. Disabling the traction control. This is hazardous when it is on and in motion with not favorable weather ie rain or snow. I have had this happen to me, driving in the rain with the abs disabled, I had to apply my brakes hard to avoid rear ending the car in front of me who had hit their brakes to avoid an accident as well. I have replaced hub assembly, rotors brakes, brake calipers, brake hoses the whole nine yards. Was told by one mechanic that when the traction system lights are on and abs is disengaged this causes higher wear and tear on the rotors and brake pads. Was also told that the abs wiring harness is too short, so it gets pulled when making turns. This issue will also happen if I go over bumps, like railroad tracks, the small street ditch for rain at the end of a driveway. Sometimes I just start the car up and it will immediately come on. I also had the side sear front passenger airbag deploy when a friend closed the seatbelt in the door. The car was in drive, however it was not in motion. The buckle got stuck on the frame at the lock latch. The door flew back open, air bag deployed, and all interior lights on the car as well as the dash lit up.
Abs light and awd disable, brakes locking up.
