Power Steering Failure

These vehicles have power steering units which may fail while driving.  Loss of power steering is most noticeable while driving slowly or parking, resulting in a heavier feel at the steering wheel. Slow speed maneuvers can become difficult and potentially unsafe. Dealers will replace the affected components free of charge. This recall is an expansion of an earlier GM recall (14V-153) to cover additional vehicles.  

Various 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.

Transmission Shifter Position Inaccurate

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.

I have just bought a 2007 G6 GTP 4dr Sedan with the 3.6 VVT engine and 56,000 miles. This is my second G6, previous was a 3.5-V6 SE traded after 110,000 miles. Love the looks, ride and handling of this car. I'm a Brit and this car is as close to Euro cars as you'll get from this side of the pond. Performance is right up there with my 3-liter Jag X-type (smaller car) space inside is better th...
Good car I have had for 8 years. Picked as certified car it's a base model with a four cylinder. G6 runs and drives like new good car but things are happening quickly as brakes need replacing more often. Steering pump just went out at 110K, NOW I need to replace 02 sensor and new starter. Interior dash light keeps flickering its the check engine light had several mechanics believe a malfunction...
Starting at 46000 miles my service air bag comes on and off.More often in the winter.I would like to know where the connection is so I can fix it.Would be good if Pontiac would put that problem on recall.
