Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 330i xDrive.
The 2021 BMW 330i xDrive carries EPA fuel-economy ratings of 25/34/28 mpg and uses an automatic (S8) transmission, while routine maintenance calls for 5.1 qt of 0W-20 engine oil. Reliability records for this model year count only three total owner complaints, with the power train, electrical system, and engine cited as the top complaint areas, alongside five recalls. That low complaint volume places this model year among the more lightly reported entries in the 330i xDrive reliability history, meaning researchers should treat those five recalls and the specific power train, electrical system, and engine areas flagged as the central data points for assessing its overall dependability.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2021 BMW 330i xDrive dominate in one area — the power train,electrical system,engine, 1 of 3 reports (33%), well ahead of the next concern. None of this vehicle's 5 recall campaigns target the power train,electrical system,engine, so those reports read as owner-reported wear-and-tear rather than an acknowledged defect. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the power train,electrical system,engine pattern above. These are tallies of what owners actually reported to the federal government, not an editorial score — and higher-selling models naturally rack up more reports.
