The car shakes when turning slightly to the left at approximately 50 mph. I came to find out from a garage that the lf control arm needs to be replaced. You can actually wiggle the tire from left to right when it is up on a jack. Two years ago, the right side had the same problem and was replaced.

I first noticed this last year when I went to NY for thanksgiving. Everytime I turned to the left my car would shimmy and shake, I was told I was missing a weight on my rim so I didn't think anything of it. As the year went on it would only happen every so often and at times would do it at all. It started to act up again but wouldn't stop and even stepping on my brakes would cause it. I brought it to a local shop and they advised that my ball joints were shot and to bring it to a dealer. So I did this and then the dealership then tells me that my ball joints are shot, which then ruined my rotors (brakes are fine) and that my hub bearings could also be ruined. With that being said they said I needed 3 more tires...I've already went through 9 of them. When I talked to the guy at the first shop he said that I only need one tire and the rest are fine so not sure why the dealership would tell me this. It was over $1,000 to fix everything not including my tires so I brought it to the local shop whom said they could order the parts and have the job done for less than $600 (no including the one tire which is $170). I contacted GM about this due to seeing bulletin's posted on here for the same issues with this car but they wouldn't help or give me an inch and basically left it in my lap and said you have to take care of it. I have also found out that the parts for my car are getting low and that when GM runs out of them they will not be making anymore. Not all of this car has after market parts. As of right now just the rotors do and the windshield wipers have to be ordered as well. I was disappointed in GM service because the first guy I talked to said it was a faulty part then the next guy who took over the case said it wasn't.

I took my car in for routine maintenance because I felt some shaking in my tires. I figured it was just in need of a tire rotation & alignment.. turns out its something wrong with my suspension arm bars. Conveniently I am 4000 out of my manufacturer warranty. I have a 3rd party warranty through american auto and they are now telling me that this is a pre-existing problem and they will not cover it. So now I am left to pay $1200 or run the risk of more damage because I am still driving my car. I can't believe that I bought a brand new car & @ only 40,000 I am having this kind of problem.

GM technical bulletin: 09203D: Front suspension lca ball joint bulletin this is a recurring problem with 2008-2009 Pontiac G8. GM hasn't issued a recall for this issue and its a safety issue. They released 4 revised control arms with better ball joints that needs replacing on all the G8. Instead of fixing the problem they released it as a technical service bulletin for dealers to take note of the issue. If the ball joints fail this can cause a serious accident or death. Cause: The rubber "boot" over the front end lower control arm ball joint may have become dislodged or torn compromising the seal. Moisture inside the ball joint seal may cause corrosion, shortening the service life of the component. #09-03-08-008: Knock clunk or click noise from front suspension over small bumps (replace front lower control and caster arms) - (Oct 5, 2009) subject: Knock, clunk or click noise from front suspension over small bumps (replace front lower control and caster arms) models: 2008-2009 Pontiac G8 attention: This bulletin is intended to correct a condition for front end knock, clunk or clicking. Vehicles previously repaired as part of campaign #09203A are to follow a different repair procedure as outlined under the correction section below.
