Are BMWs Reliable? BMW Reliability by Model
BMW reliability varies significantly by model year. Among the 6 BMW models analyzed, the X6 has the fewest flagged years at 0, while the X5 has the most at 5. The sharpest single-year spike belongs to the 328I, whose worst year logged up to 5× its own median complaint rate. Because complaint totals are not adjusted for vehicle sales, this analysis identifies strong and weak years within each model — it does not rank BMW models against one another.

BMW problem areas by service-bulletin volume
The vehicle systems drawing the most federal service-bulletin (TSB) filings across the 6 BMW models we analyze — a volume signal of where the manufacturer issues the most fix guidance. These are TSB counts by NHTSA component category, not owner-complaint counts.
BMW reliability by model
| Model | Complaints | Years to avoid | Best years | Worst year vs. its avg. |

| BMW X5 | 1,810 | 2008, 2011, 2019, 2021 and 2024 | — | 4.1× |
| BMW 750LI | 309 | 2008 | — | 2× |

| BMW 328I | 1,379 | 2011 and 2013 | — | 5× |
| BMW 335I | 273 | 2011 | — | 3.7× |
Counts are raw federal filings (NHTSA owner complaints), not adjusted for sales volume. A model year is flagged when its severity-weighted complaint rate is among the highest within that model's own history — never a comparison against other brands. Follow any model for its full year-by-year verdict. Full methodology.

FAQ
Are BMWs reliable?
BMW reliability varies sharply by model year, not by badge. Among the 6 most-documented BMW models, 5 carry at least one model year we flag to avoid on NHTSA complaint and recall data — the X6 has the fewest flagged years (0) and the X5 the most (5). 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, per-year verdicts below.
Which BMW model years should I avoid?
The BMW models carrying the most flagged years are the X5 (5 flagged years: 2008, 2011, 2019, 2021 and 2024); the X3 (5 flagged years: 2008, 2019, 2020, 2021 and 2022); the 328I (2 flagged years: 2011 and 2013). A flag means that model year's severity-weighted complaint rate is among the highest within that model's own history — it is not a comparison against other models or brands. See each model's page for the full year-by-year verdict.
Which BMW models have the fewest flagged years?
Among BMW models with enough federal complaint history to rate, the X6 carries no model year flagged to avoid. That is not a cross-model reliability ranking — complaint counts are not sales-adjusted — and a thin record is never counted as a clean one: model years with too little data rate "insufficient" instead.
How do I check a specific BMW before buying?
Start with the free BMW window sticker lookup at carwhere.com/window-sticker/bmw to confirm the exact trim and factory options, then run the $9.99 CarWhere Full VIN Report for that VIN — it includes the recall, complaint, and service-bulletin record for the exact model year plus a market price check from verified buyers.

Sources & data notes
All figures are drawn from the U.S. National Highway Traffic Safety Administration (NHTSA), Office of Defects Investigation — the public NHTSA owner-complaints data and safety 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. Full scoring at the methodology page.
