Below you'll find Pontiac G8 repair descriptions submitted through the Car Reliability Survey and the Car Repair History Survey that supplements it. Ordered by model year, with newest first.

Most cars for which no repairs have been reported are not shown. So individual repair histories should not be used to infer reliability. Instead, they provide an idea of the the repairs Pontiac G8 owners have been experiencing,

Odometer readings and costs are in local units.
