The ESP and BAS warning lights may illuminate due to a failed brake light switch. Replacement of the failed switch should correct this concern. A recall on certain 2000-2002 models have been recalled for a related issue - for more information please click here»

    The esp/bas lights turned on and then the car would not like to move as if something is holding it back or locking it up.Going slowly it started running well as if nothing happened.

    My break light switch has failed twice. Once causing the break lights to stay on continually and BAS/ESP light to illuminate. And one causing the break light to fail and and the gear shifter to lock [safety feature:(]

    Brake Lights don't work and ESP/BAS warning lights on. I will replace the Brake Pedal Switch next week and will report back if the problem is fixed.

    I replaced the Brake Pedal Switch last week and my problem is solved - Thanks a million to the people in this forum.

    ESP/BAS warning wont go away. I read is a electronic module which solder needs rectification.

    The stealership wanted to replace one sensor or another, after charging me $200 to diagnose the issue. I decided not to do it. Turning off the car and turning it back on typically turns the light off.
