2008 Pontiac Grand Prix

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2008 Grand Prix.

Body PASSENGER CAREngine Electric

The 2008 Pontiac Grand Prix Electric is a passenger car powered by an electric engine, carrying the Grand Prix nameplate through the final years of its 1990–2008 production span. With 142 owner complaints on record and just one recall, it sits near the quieter end of the model’s reliability spectrum, especially compared with the 1997 peak of 859 complaints and the 1996 low of 102. Notably, the leading complaint area is the electrical system itself, a key consideration for an electric powertrain vehicle, meaning that while overall grievance volume is relatively modest, electrical integration remains the primary source of owner-reported issues.

Factory maintenance schedule OEM · verified

Normal service, condensed from the factory interval matrix.

Under the factory schedule, replace the spark plugs every 100,000 mi; coolant at 150,000 mi. The big-interval services (at 150,000 mi for coolant, and the transmission fluid) are the ones owners most often skip — on a lower-mileage example, assume the original fluids are still in it and check them first.

Reliability & federal safety record

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.

The 2008 model year shows a marked drop in consumer complaints to 142, down from 220 in 2007 and the lowest level since 1996’s 102 complaints. Recall activity also fell to a single recall in 2008, the fewest in the dataset, while investigations remained low at one. In contrast, technical service bulletins continued their upward trajectory, reaching 871 in 2008—the highest count recorded for the generation. This pattern suggests that, although reported problems and formal recalls were declining, manufacturers were issuing more service guidance. Consequently, the 2008 Pontiac Grand Prix appears to be a comparatively reliable choice among the years examined, provided a buyer verifies that any relevant TSBs have been addressed.
