NO ELEVATED SIGNAL
28%
29 of 111 relevant owner complaints are about the engine, transmission or fuel system
No elevated drivetrain complaint concentration in the available NHTSA records for the 2021 BMW X3. Engine, transmission and fuel system account for 28% of relevant complaints.
Better than 75% of the 1,789 model years we track (2010–2023).
Does the 2021 BMW X3 have engine or transmission problems?
Not as a pattern, going by owner complaints. 29 of 111 relevant complaints filed with NHTSA about the 2021 BMW X3 concern the engine, transmission or fuel system (28%). For comparison, the 2020 scores 41% and the 2022 scores 21%. This describes the model year, not any one car: a well-maintained or already-repaired example can be fine, and a clean model year can still have a bad car in it.
Manufacturers fix things mid-generation. A bad year next to a clean one is common; the fix usually arrived in between.
