NHTSA — Engine And Engine Cooling Problems

CarComplaints.com Notes: The 2009 is starting to have the same problems as previous model years, including the headlights blowing out due to bad connectors.

The wiring harness connections aren't a big deal to replace, as long as your dealer or mechanic doesn't charge you an arm & a leg to "diagnose" the problem.

The contact owns a 2009 Pontiac G6. The contact stated that after the vehicle was serviced under NHTSA campaign number: 14V252000 (electrical system, electronic stability control, exterior lighting, service brakes, hydraulic, vehicle speed control), the cooling fans activated independently causing the air conditioner to fail. In addition, the tire pressure warning light illuminated, but the tires did not need air. The vehicle was taken to the dealer where it was diagnosed that the temperature gauge needed to be replaced. The vehicle was repaired, but the failure persisted. The failure mileage was 88,000. The VIN was unavailable.

G6

  • 6 miles
The contact owns a 2009 Pontiac G6. The contact stated that the steering would continuously fail sporadically and when first starting the vehicle, there was an abnormal noise from the engine area. The dealer replaced the threading in the steering column twice to no avail and the dealer never gave the contact a reason for the failure. The dealer also attempted to detect the engine noise but was unable to diagnose what was causing the noise. The vehicle was not further repaired. The failure mileage was 6 and the current mileage was 44,000.

I purchased a 09 Pontiac G6 on July 28th 2010 it had 46,000 miles 2 weeks after I bought it cuts off for no reason in the middle of the street and would not crank up it was towed to the dealership and kept it for 9 days and still would not crank they got it to crank and then lock the keys up while having it running cause the door unlock and lock on their own but didn't know why it cut off and would not crank. So I got it back 2 week later it cuts off again while driving and gave no sign it was going to cut off and would not crank so I am stuck in the road again stranded for an hour I get it crank take it back to the dealer ship they don't know what's wrong it cuts off again while driving. Take it back they don't know what's wrong and it cuts of about 6 to 8 more time while driving I take it to the dealer ship and they say the same thing and mind U these are all GM dealership and I used 3 different ones and they all say the same thing so it cuts off again I call GM myself and file a complaint they were no help and it stills cuts off til this day and it has an electrical problem as well cause the lights dim in and out when you turn on the air or heat or let the windows down or lock and unlock the doors. The engine runs rough and wheels sound like they about to come of while driving this is a bad car it looks good but drives bad and it not safe when the people who made it cant tell you why it cuts off while driving this very dangerous.
