Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2003 M5.
The 2003 BMW M5 is an E39-platform passenger car equipped with a 6-speed manual transmission and an engine requiring 6.9 quarts of oil — figures that, alongside EPA ratings of 12 city, 19 highway, and 15 combined mpg, paint a picture of a substantial, thirsty powertrain. Within the M5's complaint history spanning 1990 through 2022, this model year records 18 total owner complaints and three recalls, with air bags as the top concern. That places 2003 well below the 2006 peak of 123 complaints and closer to the low-water mark of a single complaint in 2010, suggesting this model year represents a comparatively settled point in the E39's reliability record rather than a trouble spot.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2003 BMW M5 sits at the latter end of its generation's federal record arc, following a significant spike in reported issues that began in 2002. While the 2000 and 2001 models experienced relatively low federal involvement with just 4 complaints and 10 TSBs each, 2002 saw a surge to 20 complaints, 4 recalls, and 49 TSBs; the 2003 model year maintains these elevated figures with 18 complaints, 3 recalls, and 52 TSBs. For the 2003 model specifically, Air Bags represent the largest complaint area with 7 reports, followed by the Electrical System with 3, and the record includes 1 crash and 1 fire complaint, though the data does not specify root causes. This trajectory implies that the 2003 model did not benefit from the relative stability of early production years and instead carries the heightened service complexities introduced in 2002. Consequently, a used 2003 M5 represents a riskier purchase, requiring rigorous pre-purchase inspection of the airbag and electrical systems, making it a less favorable year to buy compared to the lower-complaint 2000 and 2001 variants.
