First noticed as cruise stopped working. Dealer applied diaelectric grease to BCM connectors, worked for about one day. Then I realized my brake lights were on all the time, dealer replaced Brake Pedal Position Sensor (BPPS). Worked great for 5 days. Now dealer thinks the BCM needs to be replaced because they cannot even calibrate the BPPS but htey may try another new BPPS first. Very frustrating, dangerous, and costly.
brake lights come on while driving and not pushing the brake...after pushin brakes they go off but come back on and stay on

Brake lights come on when shifting out of park and stay on until I put it back into park! can't drive it, BCM and recalibration/programming to expensive so I have a perfectly good car (except the fore mentioned) and haven't moved it out of my garage for a year!

Brake lights work on and off - I was told by the GM dealership that I need to get a new BCM before more problems occur.
