Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2001 325CI.
The 2001 BMW 325CI occupies a specific space within the E46 platform lineage, pairing a 5-speed automatic transmission with an EPA fuel economy rating of 20 combined mpg and an engine requiring 7.0 quarts of 15W-40, 10W-40, or 10W-30 API SJ oil. However, this model year sits at a more turbulent position in the platform's reliability history, marked by 49 owner complaints and 6 official recalls. Because air bags constitute the top complaint area, researchers evaluating this vehicle must account for these prominent safety-related concerns rather than relying solely on the E46's generally robust reputation.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2001 model year shows a dramatic spike in complaints (49) compared to just 6 in 2000, alongside a doubling of recalls (6 vs. 3) and a jump from 1 to 16 TSBs. This places the 2001 325CI at a clear peak in the early-generation trend, with the data indicating a significant increase in reported issues rather than a plateau or decline. The top complaint areas—air bags (11), engine & cooling (7), and powertrain (5)—along with 6 fire complaints and 1 crash complaint, suggest multiple systems are affected, though the data does not specify root causes. Without later-year figures, it is impossible to say if this spike was an anomaly or the start of a worsening pattern, but the sharp rise from 2000 is a clear warning. **Given the high complaint volume and multiple recall/TSB actions, the 2001 325CI is a riskier buy than the preceding 2000 model; unless you have a detailed service history addressing these areas, it is best avoided.**
All 49 complaints on record, top 8 components.
