After going through this and another thread about the flasking "BRAKE" light, I am scared that something has or is on its was on failing. Happened to me today, and I turned the car off, checked the gas cap, and the car was normal. Havent gotten to drive it after going home since the incident, but am nervous due to the fact it was stuck ON, and could not move the car.
130ish to get the dealer to pull the codes for the PB module, and now 1400 to replace the module and PB actuator. I wish these cars came with a manual PB.
This just started happeing with my 2010 2.5i CVT with 106k, and I will update if this problem still happends.
