"charging system failure" has appeared at least 12 times on the driver's message console that I have documented. It is also accompanied by the fan blower repeatedly cutting in and out when turned on. This has happened just about every time the fan is turned on. Have taken the vehicle in to have the problem checked at lambert Pontiac-Buick in cuyahoga falls, ohio, and they stated they ran a computer diagnostic and could not determine what the problem was, and stated there was nothing they could do about it. Also, one time while accelerating it sounded as if the engine were about to cut off, but it did not. Vehicle only has 3200 miles on it.*ak

11/14/2016 171,850 mi ODI #10925726.0

During hard braking, engine oil drips onto the engine exhaust manifolds. There is a strong smell of burning oil when parking the car after driving. The VIN was originally listed as being eligible for NHTSA recall # 15v201, but a recent search does not list it any longer even though it exhibits the condition. I am concerned with the risk of an engine compartment fire if this is not repaired soon.

11/29/2007 12,000 mi ODI #10210294.0

My horn has failed on 5 occassions. Pontiac has issued a service bulletin to fix this intermission horn failure, but the fix does not work. I have had several close calls where other motorists have pulled out in front of me and I have not been able to warn them, as the horn failed. I hope this issue can be corrected properly before and accident occurs. Also, Pontiac has a problem with a known defect in their steering gears that they only replace when it fails and only cover if it is in the warranty period. This problem is caused by an internal leaking of the power steering fluid that is not detected because there are no external signs of the leak. This too is a safety concern. *tr

Major leak occurred 10/2009. Coleman told me it was not covered under their policies. *tr

I was coming up the street and could not see the light due to poor visibility. The sun was in my eyes. I didn't not see the red light and ran through it hitting an older Jeep. I was going between 35-45 MPH and my air bags did not deploy ever though it was a head on collision. The car needs the whole front half replaced. The bumper cover, actual bumper, bumper absorber, bumper support, headlights, headlight bracket, fog lights, hood, and both fenders. I suffered a concussion and severe bruising from hitting the steering wheel. *tr
