2004 Pontiac Bonneville

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2004 Bonneville.

Body PASSENGER CAR

Classified as a passenger car, the 2004 Pontiac Bonneville utilizes an engine requiring 4.5 quarts of 5W-30 API oil. This model year recorded 28 total owner complaints with zero recalls, identifying the electrical system as the top complaint area within the 1990-2005 model complaint history. These figures place the 2004 version near the bottom of the recorded spectrum, sitting just one complaint above the 2005 low of 27 and drastically below the 1998 peak of 299. This positioning defines the vehicle as a high-reliability entry relative to the model's broader history.

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

From the factory this vehicle uses a BCI 100 · 770 CCA battery, OE oil filter 12731175. Note the factory fuel filter is now discontinued — plan on a superseded or quality aftermarket equivalent, which the part pages below list where known.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 engine oil and filter every 7,500 mi; 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.

Every 7,500 mi	Engine Oil (drain & refill) · Engine Oil Filter (replace) · Tire & Wheel Assembly (rotate)
Every 30,000 mi	Engine Air Filter Element (replace)
Every 100,000 mi	Spark Plug Wires (inspect) · Spark Plugs (replace) · Transmission Fluid & Filter (replace)
At 150,000 mi	Accessory Drive Belt (inspect) · Engine Coolant System (drain, flush & refill)

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 2004 Pontiac Bonneville marks a clear inflection point in its generation’s federal record, representing the lowest complaint volume (28) and zero recalls or investigations—contrasting sharply with the mid-cycle peak of 299 complaints in 1998 and elevated recall activity in 1999–2000. Complaints declined steadily from 2001 onward, while Technical Service Bulletins (TSBs) surged, suggesting GM addressed persistent issues through service guidance rather than formal recalls. The 2004 model’s top complaint areas—electrical system (8), steering (5), and power train (3)—mirror trends from prior years, though their frequency is notably reduced. With no crash-related complaints and only one fire report, the data implies improved reliability relative to earlier model years. This year sits at the tail end of the generation’s quality arc, where complaints plateaued at historic lows, making the 2004 a comparatively strong candidate for a used purchase.
