Failure of the electronic brake control module in a 2003 chevy Impala. Could be dangerous, and after doing some internet searching, appears to be a common problem and very expensive to repair. Car has less than 100,000 miles on it. Also, transmission failed at about 80,000 miles.
I purchased my 2003 chevy Impala in 2009. Car ran perfect when we purchased it. After 6 months the transmission started to slip. That is not the major issue. The major issue is that the car does not start all the time. Changed battery and it still does not run. It will start but only runs until you put it in gear. It then stalls out! this car has been great but is not unreliable. .
Failure of onstar to contact me when air bags deployed in accident.
Vehicle was on an incline at a complete stop, when the gas pedal was depressed, vehicle rolled backward.
