Pontiac G6 Poor Terminal Contact at BCM Connectors May Cause Electrical Issues

(37 reports)

brake lights don't work right,cruise control doesen't work right,radio doesn't work right, door locks don't work correctly -
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 stay on while driving and won't go off till I press or tap the brakes. When I release the brake lights come back on with in 3 to 5 secs later. I have replace the brake switch twice and it fixed it for 2 or 3 days but the problem returns -
Same problem with brake lights. They go on when driving and off when pedal applied. There is a recall for G6 up to 2007 for this due to fatal accidents. Still waiting on 2008 and up recall. Quick fix pull the BCM and lube the heck out of it with dielectrical grease. Wiggle it back into place and push it in hard. Try brakes again - if lights are still on put more grease on it. Issue being is the connectors on the BCM are corroding, you can also clean the connectors and grease it up too. Due to poor placement condensation from AC creates humidity and corrosion with the BCM. Been dealing with this issue for a few years now. -

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. -
Headlight low beams do not work. Move wiring harness around and they will work for a short amount of time before not functioning again. -

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.
