Reliability & federal safety record

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 128I Coupe dominate in one area — the air bags, 22 of 30 reports (73%), well ahead of the next concern. That matters, because the air bags are also the target of recall 20V-017 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 2 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the air bags 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.
