UNINTENDED ACCELERATION WHILE BRAKING ON MORE THAN 1 OCCASSION
I have been experiencing unintended acceleration when I press on my brakes. Fortunately, there hasn't been any accidents yet but it's a very dangerous situation.
ANOTHER DRIVE ADVISED US THE BRAKES LIGHTS WERE NOT FUNCTIONING. DEALERS TOLD US THAT THE UNIT CAME WITHOUT A RELAY POWER FOR THE BREAK LIGHTS AND PICK ONE FROM ANOTHER CAR TO MAKE THE REPLACEMENT.
