FAQ
Are BMWs reliable?
BMW reliability varies sharply by model and year, not by brand. Across the 6 most-documented BMW models, 4 carry at least one model year we flag to avoid on NHTSA complaint and recall data. The 750LI and X6 carry no year we flag to avoid. These are raw federal complaint counts, not adjusted for how many vehicles BMW sold, so they can't be read as a single cross-brand reliability score — use the per-model verdicts below.
What is the most reliable BMW?
Among the BMW models we analyze, the 750LI and X6 carry no model year flagged to avoid in the current federal data — the cleanest records in the lineup. Reliability still comes down to the specific model year, so check the year-by-year verdict before buying.
Which BMW models have the most years to avoid?
The BMW models carrying the most flagged years are the 328I (2 years flagged, worst up to 5× its own average), the X5 (5 years flagged, worst up to 4.1× its own average), the 335I (1 year flagged, worst up to 3.7× its own average). A flag means that model year has one of the highest severity-weighted complaint rates within that model's own history — it is not a comparison against other brands.

Sources & data notes
All figures are drawn from the U.S. National Highway Traffic Safety Administration (NHTSA), Office of Defects Investigation — owner-filed complaints and recall campaigns — across the 6 most-documented BMW models and every model year on record for each. Retrieved July 2026. Counts are raw federal filings and are not adjusted for the number of vehicles sold or registered, so they cannot be read as a single cross-brand reliability ranking; each model year's verdict compares it only against the rest of that model's own history.
