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

    A/C works intermittently. Driver's side low beam headlight works intermittently even though the bulb has been replaced three times. Driver's side rear door will not unlock with remote entry or with driver's side controls. Engine light comes on and goes off intermittently. Water temperature gauge works intermittently. Service tire monitor light is on.

    There is a pending recall for electrical wiring issues and we have neither received contact about the recall or any attempts to perform those recalls

    Solution: Frank Kent Cadillac offered to effect all repairs including brake job and tie rod end replacement for $4000 minus 10% discount. When I contacted GM for help, I was told that GM would partner with the dealership and honor the 10% discount.
