Owner-reported issues, recalls, investigations and service bulletins on record with NHTSA — an unfiltered look at what owners actually experience.
The 2023 BMW X4 sits in the latter, calmer portion of this generation's lifecycle, which peaked in recalls during 2019–2021 (7–10 recalls annually) before tapering off. For the target year, federal data shows 7 complaints and just 2 recalls—a notable drop from the 2020 peak of 14 complaints and 10 recalls, and roughly on par with 2022's 3 complaints and 5 recalls. The complaint areas for 2023 are spread across Engine & Engine Cooling, Unknown or Other, Visibility/Wiper, and Electrical System, each with a single complaint, suggesting no single dominant failure mode; the data does not specify root causes. Notably, 2 of the 7 complaints involve crashes and 1 involves fire, which is worth attention even though the overall volume is low. With recalls falling to 2 in 2023 and just 1 in 2024, the data indicates BMW has worked through most of this generation's major regulatory issues by the target year. On balance, the 2023 X4 represents a relatively low-risk point in the generation's arc—complaint and recall activity is well below mid-cycle peaks—making it a reasonable used purchase, provided the two recalls have been addressed and the buyer is aware of the small but present crash- and fire-related complaint flags.
