Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2015 BMW M235i xDrive lead in one area — the electrical system,exterior lighting, 1 of 5 reports (20%), well ahead of the next concern. None of this vehicle's 2 recall campaigns target the electrical system,exterior lighting, 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 electrical system,exterior lighting 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.
