2008 Pontiac G6 RecallsVarious Electrical Concerns
Increased resistance in an electrical connection at the body control module (BCM) may result in voltage fluctuations in the brake pedal sensor circuit. These fluctuations can cause concerns with various systems that monitor the position of the brake pedal, any of which would increase the risk of a crash. Dealers will attach the wiring harness to the BCM with a spacer, apply dielectric lubricant to both the BCM and harness connector and the BAS and harness connector, and will reprogram the brake pedal sensor to correct these concerns.
The shift cable may fracture, which can mislead the driver into thinking the transmission is in a certain gear, while actually being in another. This can cause a safety issue, as when "Park" is selected, the vehicle may not be securely in "Park". Dealers will replace the shift cable assembly and mounting bracket free of charge to resolve the concern.
On vehicles equipped with a 4-speed automatic transmission, the tabs on the transmission shift cable end may fracture and separate. If this were to occur, the shift lever and the actual position of the transmission gear may not match. The driver would be able to move the shifter to "Park" and remove the ignition key, but the transmission gear may not be in "Park." The vehicle may not be able to be restarted and the vehicle could roll away after the driver has exited the vehicle, resulting in a possible crash without prior warning. Dealers will install a retainer over the cable end or replace the shift cable as necessary. The General Motors recall number 12106.
