Issues? Have the suspension checked. Once you’ve determined the stereo system is in good working order, switch it off and listen for popping, clunking, grinding or snapping sounds from the front end while travelling over bumps at various speeds and angles. Any unwelcomed sounds likely mean a suspension component is worn out or in need of replacement. A well-documented problem with premature lower control arm wear resulted in a service bulletin-- so a GM dealer should be able to address the problem in quick order.
Unwelcomed vibrations at speed could be caused by a faulty driveshaft, though this problem is also easily fixed. Other potential issues deal with engine control sensors that may cause lumpy power delivery, a sporadic idle or illumination of a check-engine light.
As with any performance car, shoppers are advised to check the condition of consumable parts like brakes and tires, ensuring they haven’t been fried by a seller that was a closet burnout enthusiast. If the G8 you’re considering needs new rubber or pads, call it into pricing negotiations.
Other problems look fairly few and far between. Aside from a few mentions of possibly faulty transmission control electronics, the G8’s driveline looks like a solid, robust and reliable performer. Of course, remaining factory warranty should provide used G8 shoppers plenty of confidence, too.
Those after something sporty, aggressive, rear-drive and with an available fire-breathing V8 shouldn’t expect any issues on a well-maintained used G8 model.
