Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2010 G5.
The 2010 Pontiac G5 pairs a 4-speed automatic transmission with EPA fuel-economy ratings of 24 city, 33 highway, and 27 combined mpg, and is serviced with a 4.5-quart fill of 5W-30 API oil. Its owner-reported reliability paints an unusually clean picture for the model year: just 2 total complaints, with steering as the most-cited subsystem, against a backdrop of 4 recalls. Set against the 2007–2010 production run—where 2007 alone drew 187 complaints—this final-year G5 stands as the quietest iteration on record, a useful anchor point for any researcher tracing the nameplate's reliability arc.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2010 Pontiac G5 shows a dramatic drop in reported complaints, falling to just two incidents after a steady decline from 187 in 2007 to 76 in 2009. Recalls also eased slightly, decreasing from six in 2007 and 2009 to four in 2010, while investigations remained low (one) and technical service bulletins (TSBs) continued an upward trend, reaching 1,036— the highest of the four‑year span. This pattern suggests that the model’s most severe reliability issues were largely resolved before 2010, leaving only isolated steering‑related concerns and no recorded crash or fire complaints for that year. Because 2010 sits at the low‑point of the complaints curve and shows no safety‑related complaints, it represents the most favorable year in this generation for a used purchase. **Takeaway:** 2010 is a strong candidate year to buy a Pontiac G5, given its minimal complaint record and modest recall count.
