This is the most up-to-date car reliability information available anywhere for the Pontiac G8. TrueDelta's Car Reliability Survey results are promptly updated every three months. Others can be over a year behind. What you'll also find only here: actual repair rates (the average number of trips to the repair shop each year), and not just dots, for a clearer idea of how much competing cars truly differ in reliability.

Members: to view car reliability information for:

  • up to ten competing car models, instead of up to five
  • car models for which fewer owners responded--marked "join to view"

General Notes

How do we select "competing car models"? Users of TrueDelta's car price comparison tool most often compare these cars to the Pontiac G8.

Models and statistics marked with an asterisk* have very low sample sizes. These results, visible only to logged-in members, provide only a rough estimate of car reliability.

Ultra-low repair rates: Any result under 20 repair trips per 100 cars is likely a result of the small sample size, and should be expected to increase to 20 or so in future updates.

New models often start out with high repair rates, and then improve during the model year as the manufacturer identifies and addresses common problems.

Full set of Car Reliability Survey results in one huge table.

Methodology

Description of the research process.

Only successfully completed repairs are currently included in the analysis. Routine maintenance, most wear items, recalls, and problems fixed with just a reflash or warning light reset are not included.
