“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. …”
NHTSA complaint #10443281, filed 2012-01, 54,000 miles“While driving the vehicle the front suspension shakes and clunks while driving at any speed. Both ball joins have tears in the rubber boots which I'm sure causes water and road debre to enter ball joint and corrode. This is a huge safety concern for me and when a ball joint lets go it can be fatal sending the car in any unchosen direction. Please note this is happening to every single Pontiac G8 owner I've come across. This is life threatening, ball joint lets go on the highway and the car will go into a roll. Thank you for your time and consideration”
NHTSA complaint #10979964, filed 2017-04, 67,000 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. …”
NHTSA complaint #10576979, filed 2014-04, 49,035 miles“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. …”
NHTSA complaint #10339586, filed 2010-06, 14,034 miles“In april 2009 my Pontiac G8 began making groaning and cracking noises. Observation indicate that noise is coming from the front of the car and is most prevalent when the car is warm. Research on the numerous websites indicate that this is not an uncommon problem. Unfortunately, the dealers don't seem to understand the severity of the problem and the potential safety impact of losing control of the automobile. So far the most common response seems to be to ignore it or provide a piece meal solution. I believe it is only a matter of time before the steering is effected and an accident occurs. …”
