Every year or so ,without fail I need to replace to brake light switch. The Bas/Esp light goes on and will want to lock out the transmission shifter. I have owned my car for 7 years and have replaced the switch 6 times. It is not a difficult DIY repair and takes about 20 minutes to complete. The switch is $25 and the dealer will charge you about $150 for labor to install it.

I have experienced this problem three times.Once at 28000 mi then 49000 and then at 85000 mi. Something must be wrong with the design or quality of the part.
