Fitment & sizes

Replacement part sizes and factory part numbers — battery, bulbs, filters and belts.

From the factory this vehicle uses a BCI 86 · 590 CCA battery, OE oil filter 12731172. Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known. Each part links to every other vehicle that shares it, so a part you already stock may fit more of your fleet than you'd expect.

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.

In 2005, the Corvette experienced 536 complaints and 6 recalls, a sharp rise from 217 complaints and 4 recalls in 2004, and a slight decline to 413 complaints and 5 recalls in 2006. This year sits at the peak of a trend that began with modest complaint levels in the early 1990s, surged through the late 1990s and early 2000s, and then tapered off after 2008. The 2005 data show the highest complaint volume of the generation, indicating a period of heightened customer dissatisfaction. The top complaint areas—Power Train (57), Exterior Lighting (52), Structure (47), and Electronic Stability Control (44)—highlight mechanical and safety concerns that were more pronounced that year. Given the record‑high complaint count and the concentration of power‑train and safety issues, 2005 is a less favorable year to purchase compared to neighboring model years.
