Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 2012 BMW 135I Coupe top in one area — the power train,engine, 3 of 19 reports (16%), well ahead of the next concern. None of this vehicle's 6 recall campaigns target the power train,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,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.
All 19 complaints on record, top 8 components.
