2008 Chevrolet Cobalt

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

Body PASSENGER CAR

The 2008 Chevrolet Cobalt is a passenger car whose engine takes five quarts of 5W-30 API oil per change, placing it squarely in the mainstream sedan maintenance routine. With 938 owner complaints logged and five recalls issued, the 2008 model year sits in the middle-to-lower range of the Cobalt's broader complaint history spanning 1996 through 2017 — notably below the 2006 peak of 2,330 complaints but well above the 1996 low of just one — with steering problems standing out as the top complaint area. That positions this model year as a relatively quieter entry in the Cobalt lineup, though the recurring steering concerns and multiple recalls make clear it is far from trouble-free.

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 federal record for the Chevrolet Cobalt generation reveals a severe complaint and recall arc that spiked from near-zero in the early 2000s to a peak of 2,330 complaints in 2006. The 2008 model year sits on the downward slope of this arc, dropping to 938 complaints and 5 recalls; this represents a significant improvement over the 2005-2007 period but remains elevated compared to the 582 complaints seen in 2010. For the 2008 Cobalt, steering is the top complaint area with 223 reports, followed by the fuel/propulsion system at 185, and the data also records 74 crash and 15 fire complaints, though the specific root causes are not specified. Although the declining complaints and high number of 957 technical service bulletins suggest early-generation issues were being actively addressed, the vehicle remains firmly situated within a notoriously problematic era. Consequently, while the 2008 Cobalt is a better statistical choice than the preceding three years, the persistently high complaint volume and severe safety metrics make it a risky purchase that should only be considered if thoroughly inspected for steering and fuel system defects.
