G8 6-cyl

  • 49,035 miles
While making a some what sharp turn to the left on a freeway at approx 60 miles per hour (legal speed for situation) noted vibration in right front suspension. It felt like the tire was attempting to come off the rim.. I backed off and the problem dissipated. I took the car to the dealership and it was determined that the right front rear lower support arm had severe play in the ball joint. The same issue is present with less wear in the front left lower control arm. The play has caused premature wear in the right front tire. Tires have been rotated regularly at the dealership at suggested 5,000 mile time frame. The dealership did not detect any problem in the suspension during any of the scheduled maintenances. Considering the mileage on the car there is unreasonable wear occurring in suspension part creating a dangerous situation.

The contact owns a 2009 Pontiac G8. The contact stated that while driving approximately 55 mph, the vehicle wandered out of the lane. The vehicle was taken to an independent mechanic who stated the failure was contributed to the front lower control arm and loose ball joints. The vehicle had not been repaired. The vehicle was also taken to a dealer who was unable to duplicate a problem. The manufacturer was notified of the failure. The approximate failure mileage was 30,000.

This car clearly has lca (lower control arm) issues. I had mine replaced 10K miles ago. They are noisy again. With just a little research you will find that around 80% of G8 owners have front end suspension issues. Why isn't GM recalling this?

G8 8-cyl

  • 54,000 miles
I recently encountered a clunking/knocking noise in the front drivers side of the vehicle when going over small bumps, as well as severe shaking/vibration when braking and steering. This made it difficult to control the vehicle, especially at higher speeds and on freeway curves. Since the vehicle is no longer under warranty, I took the vehicle to a trusted local mechanic. They informed me that the front lower control arms needed replacement. After doing some additional research, it appears there were both a service bulletin and a customer satisfaction campaign for issues with the G8 suspension, specifically the lower control arms. These issues included problems with the rubber boot over the front end lower control arm ball joint, which may become dislodged or torn compromising the seal. Moisture inside the ball joint seal could cause corrosion, shortening the service life of the lower control arm. My local mechanic completed the repairs and also did a front-end alignment. They supplied me with the defective lower control arms, which showed evidence of the torn rubber boot on both arms and corrosion. After contacting with gms customer service, they are not even interested in discussing further because I did not take it to a dealership (who charge over $1,000 for these repairs). I even offered to send them the defective parts, but they weren't interested. They used the excuse that the recall only included certain VIN's and mine wasn't included, yet I had the same exact part failure and symptoms as other vehicles included in the recall.

Above about 40 mph the steering wheel has a shake and the dealer keeps telling me that they do not feel it, seems like they want nothing to do with it. This is a widespread problem that seems like GM wants nothing to do with. This is a link to a 30 page thread of people complaining about the problem and almost every person that is having the issue has not been resolved. This is currently an annoyance but it may be a sign of a failing steering / suspension part. www.G8board.com/forums/showthread.php?T=46325.

My 2009 Pontiac G8gt with 14,000 miles has had a front end shake in it since new. Have had it back to the dealer 8 times to have it fixed to no avail. He car has started to wander back and forth while driving on the highway so I decided today I was inspecting it to see if I could find anything. The last time I had it to the dealer I told them I could her the front strut bushings going bad this was about 1000 miles ago. Today during my inspection I found that both front strut bushings are bad. I was checking a couple of forum boards today and this seems to be a very common problem for this car and Pontiac an GM are well aware of it. Why haven't they are anybody made GM step up and fix this before somebody get hurt or killed?

After only 11,000 miles my front right ball joint was bad and a wobble was noticed when braking hard. Dealer had to replace the lca to fix it. This is a safety issue with the premature failure and could eventually cause injuries if a more solid fix isn't completed.
