I have a 2008 Pontiac g8 gt. The issue is the front suspension. Around 43,000 miles the car started getting very bad sounds and vibrations coming from the front of the car. When applying the brake under certain speeds and conditions the car will go into a violent shake. When driving straight I'm fine but if I head into any kind of a curve in the road the steering wheel is shaking badly and…
Ball joint failure, both sides, front suspension. Loud clunking over irregular surfaces and bumps, vibration in front end, shaking/strong vibration during braking. Inspected by dealer, all ball joints on driver and passenger side failing. Gm warranty personnel directed me to continue driving the vehicle, they refuse to cover a loaner or rental and declared that it is "a non-safety issue". Since…
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. *tr

Common questions
How serious is the suspension problem on the 2008 Pontiac G8?
It's a documented issue but not catastrophic. 9 complaints have been filed. Repairs average $900 and most owners catch it before it causes a breakdown.
At what mileage does the suspension typically fail?
Across the 9 complaints that reported odometer mileage, most suspension failures cluster between 23,000 and 43,000 miles, with the median around 38,500. A quarter of owners report trouble before 23,000; a quarter make it past 43,000. Maintenance history matters more than the odometer alone — this is the reported failure window, not a guarantee.
What does it cost to fix?
Independent shops typically charge around $900 for suspension repairs on this vehicle. Dealer pricing tends to run 20-40% higher. The exact figure depends on the specific failure mode, parts availability, and your local labor rates. If you're outside factory warranty, an extended service contract often covers this category.
Are there any recalls related to suspension?
No active recalls currently cover suspension issues on this vehicle. The complaints filed represent owner-reported failures that haven't risen to the level of a manufacturer-issued recall — but they're still worth knowing about before you buy or budget for repairs.
