There are no warning signs. This can happen any time you turn on the car but might not always happen. It can also prevent you from turning off the…

   The Dash display (shows the speedometer, warning lights, etc) won't come on, and the rear back up camera doesn't either. They seem to both stop at the same time on start up. The car seems to run fine otherwise.

    Under hard braking (over 50% of the pedal) the front passenger wheel applies all the force to stop the car to that one tire causing it to lose traction and skid. Brakes are insufficient to properly stop the vehicle and no warning lights are illuminated on the dash. Actually more than half of the time the whole dash does nothing, no MPH, no gas gauge, nothing but a blacked out information less panel. Then to top it off the car only has one headlight bc it blows what ever…
