What owners report
I am the owner of a 2010 Pontiac G6 with a 4-speed automatic. My car was serviced for a recall in for the transmission shifter cable. To cure the fix the recall(12106) called for a retainer to be added to the cable to prevent the breakage from occurring. Recently not even two years later as I was pulling into my apartment complex driveway the shifter cable broke causing the my steering and drivability to be impaired. I was able to apply the brakes, but I could not drive the vehicle any further. I put the car in park and exited my vehicle to check out the problem as my car started to roll away. I ran to catch the car trying to prevent my car from running into another car, pedestrians and a nearby items. I was injured in the process. The injuries were not life threatening, but they consisted of bruising, back injuries and my foot being ran over. My car also has scrapes. …
Tl* the contact owns a 2010 Pontiac G6. While the cruise control was activated while driving approximately 70 MPH, the ESC, traction control, and engine warning indicators illuminated. The cruise control deactivated independently. The vehicle was maneuvered to the side of the road where the engine was turned off. The vehicle was restarted and the gear lever failed to shift from park into the drive position until after several attempts. The vehicle resumed normal operation; however, the warning indicators remained illuminated. The vehicle was serviced previously per NHTSA campaign number: 14V252000 (electrical system, electronic stability control, exterior lighting, service brakes, hydraulic, vehicle speed control). The recall remedy was insufficient and the failure recurred. …

The power steering mechanism stopped working, therefore I cannot turn the wheel. The gear shifter/drive train stopped working, therefore I cannot go into reverse, I am stuck in 3rd gear. It is unsafe because when I go to turn I cannot turn the wheel at times. I have issues braking. All of these issues are recalls on the vehicle. GM states that the recalls were performed seven years ago in San Juan, Puerto Rico, I have no way to verify that information nor any assurances that the parts used weren't faulty. I request new repairs under the recall warnings.

Brake lights stay on when the car is in drive. Cruise control will not work. There are other intermittent electrical issues that are not safety related. With the brake lights always on, other drivers don't know when I'm stopping. The problem is ongoing and has been confirmed by an independent mechanic. there were no warning lights or messages. the problem started several years ago before I owned the car.
