2001 BMW 325I

Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 325I.

Transmission Automatic 5-spd

The 2001 BMW 325I on the E46 platform pairs a 5-speed automatic transmission with an engine that takes 7.0 quarts of 15W-40, 10W-40, or 10W-30 API SJ oil and returns EPA ratings of 17/25/20 mpg. This model year marks the peak of owner-reported complaints across the 1990–2012 span, logging 155 complaints — driven primarily by air bag concerns — against six recalls, a sharp contrast to the 2000 model's single complaint. That concentration of issues positions the 2001 as the most heavily flagged year in the lineage, signaling researchers to scrutinize air bag systems and recall compliance when evaluating examples.

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 2001 BMW 325I exhibits a substantial spike in federal reporting, with 155 complaints and 6 recalls. This marks a dramatic increase over the 1999 and 2000 model years, which recorded only 0 and 1 complaints, respectively. In the context of the provided record, 2001 represents the peak of the generation's complaint and TSB arc, far exceeding the figures seen in later years such as 2011 and 2012. The most frequent issues for this target year involve Air Bags (47), Exterior Lighting (14), and Engine & Engine Cooling (12), with 8 fire and 7 crash complaints reported. The data does not specify the root causes for these failures. Due to this extreme statistical outlier in complaints and recalls, this is not a good year to buy.
