    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.
