2007 Saturn Relay

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2007 Relay.

Body VANTransmission Automatic 4-spd

The 2007 Saturn Relay is a minivan paired with a four-speed automatic transmission and EPA-rated at 16 mpg city, 23 mpg highway, and 19 mpg combined. Across the reporting window covered from 2005 to 2007, this model year sits at the bottom of the owner-complaint ledger with just 12 filings — overwhelmingly tied to the electrical system alongside a single recall — compared to a peak of 91 complaints logged for the 2005 model year. That steep drop positions the 2007 Relay as the most problem-free iteration in the available dataset, even as electrical issues remained the defining reliability thread researchers will encounter when tracing the van's three-year history.

From the factory this vehicle uses a BCI 34 · 600 CCA battery, OE oil filter 12731179. Note the factory cabin air filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 2007 the Saturn Relay saw a sharp decline in reported complaints, dropping from 91 in 2005 and 19 in 2006 to just 12, while recall activity also fell to a single recall—the fewest of the three years. The number of investigations followed the same downward trajectory, decreasing from three in 2005 to one in 2007, indicating that the model’s issues were being resolved or were less frequent. However, technical service bulletins (TSBs) continued to rise, reaching 774 in 2007 after 659 in 2006, suggesting that while serious defects were fewer, the vehicle still required a growing amount of routine corrective guidance. The top complaint areas in 2007 were limited to electrical systems and structural/lock components, with no crash or fire complaints reported, reflecting a relatively modest risk profile for that year. Overall, the 2007 model sits at the low‑point of the generation’s complaint and recall curve, making it a comparatively safer used‑car choice within the Relay line.
