Owner complaints about the 2013 BMW M6 Convertible dominate in one area — the engine, 1 of 2 reports (50%), well ahead of the next concern. That matters, because the engine are also the target of recall 12V-475 on this vehicle — so the single most useful check before buying or servicing one is confirming it was actually performed. 0 of the reports describe a crash and 0 a fire — a small share of the total, but worth weighing against the engine pattern above.
