Factory specifications, fluid capacities, torque values, EPA fuel economy and the federal safety record for the 2021 X2.
The 2021 BMW X2 carries forward BMW's compact premium crossover formula with a 5.6-quart oil sump running 0W-20 viscosity, an eight-speed automatic transmission, and EPA fuel-economy ratings of 23 city / 30 highway / 26 combined mpg. Service-brake issues anchor the eight owner complaints logged for this model year, alongside four open recalls that researchers tracking long-term cost of ownership will want to factor in. Sitting between the 2018 launch year's peak of 14 complaints and the notably quieter 2022 model year with just a single complaint, the 2021 occupies the middle band of the X2's 2018–2026 reliability arc — neither the high-water mark for issues nor an outlier on the clean side, which positions it as a useful baseline for longitudinal comparison.

Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2021 BMW X2 sits at the low point of a declining trend in federal complaints and Technical Service Bulletins (TSBs) across its generation, dropping from 14 complaints and 108 TSBs in 2018 to just 0 complaints and 34 TSBs in 2021. While recalls remained constant at one per year through 2020, 2021 still logged a single recall and an investigation, matching the pattern of modest recall activity seen in earlier years. After 2021 the data show a modest rebound in recalls (two in 2024, three in 2025) and a slight rise in complaints, though TSB counts stay relatively low, indicating that 2021 was the most trouble‑free model year in the dataset. With no crash or fire complaints reported for 2021 and the smallest number of documented issues, this year represents the cleanest option in the recent X2 lineup. **Takeaway:** 2021 is a strong candidate for purchase, offering the lowest recorded complaint and TSB burden among the years examined.
