One problem related to brake light on has been reported for the 2009 Chrysler Aspen. The most recently reported issues are listed below.
When traveling at different city or hwy speeds all of a sudden the brake light will turn on. Doesn't seem to affect the speed or braking of the car but if I apply the brake pedal while the light is on sometimes the car will pull to the left or right but when the light is off and I apply the brake pedal the car doesn't pull left or right. Once the light is on it stays on and sets a code and light stays on on until I stop the car and turn off the ign switch. I have had the car into the dealer many times and they have verified the code. They have tried different things but I still have the problem. This has happened many times over the last year.
