Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 1990 325iX.
The 1990 BMW 325iX Electric is a passenger car pairing an electric engine with a 4-speed automatic transmission. Despite a relatively low total of just 13 owner complaints, the model's reliability record is heavily dominated by issues regarding vehicle speed control. Accompanied by two separate recalls, this places the 1990 model year in a problematic position within the broader reliability history of the 325iX, meaning researchers must account for documented control system defects and manufacturer interventions when evaluating this specific powertrain.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1990 BMW 325iX dominate in one area — the vehicle speed control, 4 of 13 reports (31%), well ahead of the next concern. NHTSA has issued no recalls for this vehicle, so these are owner-reported concerns only. 3 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the vehicle speed control 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.
