Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
Owner complaints about the 1989 BMW 735I - E32 dominate in one area — the engine & engine cooling, 4 of 11 reports (36%), well ahead of the next concern. That matters, because the engine & engine cooling are also the target of recall 98V-178 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 & engine cooling 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 11 complaints on record, top 5 components.
