Sedans Pontiac G8 G8 Problems

I have had my G8 (V6) loaded, for just over 1 month and about 1000 miles. It is currently in the shop for the second time for vibrations and brake pulsations. The first time they put a set of new front tires on to fix the vibration. That didn't work. I just got off the phone with the dealership. The said they cut my brake rotors down to fix the brake pulsations. QUESTION - is cutting the rotors on a 1 month old, 1000 mile car the right way to fix this issue. Is it me or should I expect them to replace the rotors? The dealership told me GM will not cover replacing the rotors... Is this the truth?? If anyone can shine any light on this I would greatly appreciate it.

Three black hard-plastic interior trim covers on my new G8 just FELL OFF today. Two were held on by little white pushpins and one has molded tabs. WTF!

My G8 has a vibration problem. It has constatant light to medium vibration most noticible at around 68 mph. Sometimes you can see the the steering wheel buzzing and you can feel the vibration strongly thru the shift nob. I took the car to my dealer at about 1400 miles, they road force balanced the tires and then put 2 new front tires on the car. This did not help much in my opinion. I took the car back to the dealer at about 1800 miles. They road force balanced the tires again and indexed the drive shaft. This did not help significantly. I then made arrangements to test drive my car with the service manager. After driving with me, the service manager agreed my car has a noticible vibration. We then drove a different new G8 off the lot that had the same equipment as mine. Guess what? THIS G8 VIBRATED AT LEAST AS BADLY AS MINE! The service manager then promised to call Detroit to find out what else he could do. Two days later the service manager called back. He had talked to "Detroit" The answer was there was nothing else he could do. G8's JUST VIBRATE! Next I plan to call GM directly... Lets see if this works any better. |

After I installed a Magnaflow cat-back system and before I disabled AFM, my rearview mirror would vibrate enough to blur the view. |

NHTSA recalls all Pontiac G8s Pontiac and the National Highway Traffic Safety Administration have announced the recall of 35,038 G8 sedans for two separate issues. General Motors announced earlier this year that the Pontiac brand would be killed by 2010, with the G8 set to ride off into the sunset by the end of the year. According to the NHTSA’s Web site, the Pontiac G8 is being recalled for a brake light issue and a potential problem with the vehicle’s tire pressure monitoring system. The recalls cover all G8s from the 2008 and 2009 model years. Some G8 vehicles may have been equipped with an incorrectly programmed brake pedal position switch from the factory. The defect can lead to the continual illumination of the car’s brake lights, giving other drivers on the road little warning when the vehicle is coming to a stop. Due to the increased risk of crash, Pontiac dealers will begin fixing the problem June 5th. The G8’s second recall involves the vehicle’s tire pressure monitoring system. Some vehicles were equipped with the wrong programming, which could give false tire pressure readings. As a result, the system may not warn the driver when tire pressures fall below safe levels, potentially leading to deteriorated handling or even a crash. |

Replying to: pfwiz (Mar 27, 2009 5:38 am) I have had the vibration problem too. They replaced one of my tires. It helped. Sometimes the steering wheel has a vibration to it and sometimes not. IIt is different then the slight vibration you feel in the car when it goes into 43 cylinder mode. I have 2800 miles on ours. |

2009 G8 GT: Well after 2800 miles the turn signal seems to get stuck on and the repeater will not turn off automatically. I am waiting for the dealer to "contact the engineers" for a solution. My guess is either the cam or switch is starting to fail. Started to be an issue with wide turns to the left. It is now sporradic on the right turns as well and tight turns. Seems to be worse when the car is hot from sitting in the sun. Only started to happen about a weeks ago (around 2600 miles). Anyone else have this problem or recommended solutions?

this is why no matter how well the G8 performs - I don't think I'm going to buy one. When you consider the quality issues AND you factor in that Pontiac is dead, and GM is having it's own problems - do you REALLY think you're going to get quality customer care AFTER you buy it? they will tell you what you want to hear to get your money - once you have the car - you will be on your own.
