2009 Pontiac G6

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2009 G6.

Body PASSENGER CAR

Classified as a passenger car within a production run covering 2003 to 2014, the 2009 Pontiac G6 requires 4.5 qt of 5W-30 API oil and carries 5 recalls alongside 710 total owner complaints primarily involving steering. This model year sits between the generation's extremes, recording significantly fewer issues than the 1909 complaints logged in 2006 while exceeding the single complaint reported in 2003. For researchers evaluating the model's history, this year represents a moderate reliability case where steering remains the top complaint area despite the lower overall volume compared to the peak year.

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 2009 Pontiac G6 sits in the descending back half of a complaint arc that peaked at 1,909 complaints and 7 recalls in 2006, with 710 complaints, 5 recalls, and a single active investigation representing a meaningful improvement over the 20052007 crisis years but still well above the 2003–2004 launch baseline. Steering is the defining issue of 2009, accounting for 226 of 710 complaints—nearly a third of the year's total—while exterior lighting (78), combined electrical/lighting (52), and fuel/propulsion (31) round out the top concerns, and the underlying failure mode is not specified in the available data. Twenty-five crash and twenty fire complaints in this model year are non-trivial safety signals that warrant attention from any used buyer. The recall count has held at five for three consecutive years (2007–2009), meaning a 2009 buyer must verify that multiple open campaigns have been completed, and TSB volume remains elevated at 1,046, only marginally below the generation-peak 1,105 posted by 2010. The takeaway: 2009 is materially better than a 2005 or 2006 G6 but is far from trouble-free—prioritize documented recall completion and a thorough steering inspection before purchasing.
