Since day 1 I have been having the same issues with this car. Car pulls to the left when being driven along with a popping sound coming from the front end suspension. Multiply items were repaired both under warranty and out of pocket expense. Ishaft, bearings, aligned 22 times, tire balanced, new wheels put on. Same problem still persisted. Toe clips keep popping off. Car still shakes with every fix. Steering has a whine to it - power steering pump replaced, did not fix the issues. Car has 50 pages of service issues with 8 issues on a page and still not is right. Due to front suspension issues accident occurred - damaging front drivers rim and tire. Dealer would not replace or warranty even with full coverage warranty. Paid for out of own pocket. Exterior lighting also has condensation in it - both head lamps assembly and both tail light assembly. Dealer stated this was normal? …

I have a 2008 Pontiac G6, and while driving there is a knocking or sounds like something is loose on the left front suspension. They have replace the steering shaft, sway bar links, still having the problem. Had it to the dealer 3-times. I am afraid something will break and cause me to wreck. Can hear it gook hitting a pot hole in on the pavement or going down a gravel road that has pot holes. If something breaks and causes me to wreck, I will pursue if still available I will sue the dealership for not correcting this. I am tired of spending all my time at the dealership, they are suppose to have certified mechanics, but they don't take enough time to really fix the issue with my car.
This car has had numerous issues since I bought it and I have taken the car to different repair shops and none of them can figure out what is wrong but they hear the problems. The steering makes a constant popping noise when accelerating or turning the wheel, the steering wheel locks when the car is in reverse, the brakes squeak, and underneath it sounds like the bottom of the car is going to fall out. It's pretty sad when you take this car to different professionals and they can't figure out what is wrong with the car but they clearly see there is a problem. This car is dangerous and needs to be recalled. Who wants to make payments on a car with numerous issues that can't be fixed.
At 38,500 miles, have had multiple problems with steering, including 2 steering shaft replacements, steering gear replacement. Power steering will fail at various times while turning at low speeds. There is also a loud pop which the dealer diagnosed as the steering shaft, but is never fixed after replacement. Also had to have cv joint replaced at 38,000 miles due to failure. This vehicle has never been wrecked or otherwise damaged. According to the dealer, these are very common problems with G6's and should be recalled.
Vehicle makes a constant popping noise when turning, braking, or accelerating. Sometimes the steering wheel locks when trying to turn it. Underneath driver and passenger floor board it feels like the bottom the car is falling off. The brakes squeak so bad. I have taken to three shops and everyone hears the noise but can figure out what is wrong. Sometimes when I get in the car the air is on full blast with no keys even in the ignition. This car needs to be recalled. I have read so many complaints about the same issues.
There's several issues with this car. First, the front right suspension is bad causing the car to shake. Second, I suddenly lost control of the car on the highway almost causing a severe accident while driving approximately 55-60 MPH. It felt like the steering power was no longer working. Last, both back door locks stopped working a couple of months after I purchased the car. I always have to let down the window in order to manually unlock the doors. Most of these issues occurred at 46,000 miles.
