Vibration/Noise

• Pontiac technical service bulletins (TSBs) indicate that vibration and noise are common steering column issues for the Grand Prix. The noise and vibration may be experienced while turning the wheel; the noise is described as a "clunking." The issue can be solved by lubricating or replacing the intermediate shaft.
  
  

Tilt Sticking

• TSBs also report that steering column tilt sticking is a potential problem. The tilt feature, which allows you to move the steering column up or down, may get stuck in either position. A professional will have to remove the steering column's cover and check the tilt mechanism gears.
  
  

Recall

• In 2007, Dorman recalled 979 Grand Prix steering knuckles, which are connected to the steering column and help with suspension. A defective steering knuckle could result in loss of steering. You can bring your 1997 to 2008 Grand Prix to your dealership to see if it's on the recall list.
