2021 BMW X5 problems: engine and transmission complaints and recalls

HIGH COMPLAINT SIGNAL
51%
52 of 101 relevant owner complaints are about the engine, transmission or fuel system

51% of relevant owner complaints filed with NHTSA on the 2021 BMW X5 are about the engine, transmission or fuel system. That is a model-level pattern, not bad luck.

Worse than 68% of the 1,789 model years we track (2010–2023).

Excludes 7 airbag, lighting and seat-belt recall complaints that would otherwise mask the signal (unadjusted: 48%).

Does the 2021 BMW X5 have transmission problems?

Owner complaints say yes, as a model-year pattern. 52 of 101 relevant complaints filed with NHTSA about the 2021 BMW X5 concern the engine, transmission or fuel system (51%), and the largest group is filed under power train (29). For comparison, the 2020 scores 63% and the 2022 scores 51%. On a test drive, check for shuddering, slipping, delayed or harsh shifts, or a whine at speed. 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.

The percentage is each model year's drivetrain complaint share. No elevated signal describes the model year, not any one car; a well-kept example of a flagged model can still be the right buy, and any of these still needs an inspection.

Before you buy a 2021 BMW X5

Questions people ask about the 2021 BMW X5

Does the 2021 BMW X5 have transmission problems?

Owner complaints say yes, as a model-year pattern. 52 of 101 relevant complaints filed with NHTSA about the 2021 BMW X5 concern the engine, transmission or fuel system (51%). Before buying one, have an independent mechanic check the transmission and ask the seller whether it has been repaired or replaced.

Are there engine or transmission recalls on the 2021 BMW X5?

NHTSA lists 12 recall campaigns on the 2021 BMW X5. Whether a specific car still has one open depends on its VIN.

Which BMW X5 years are better?

Among the BMW X5 years we track, the 2023 (39%), the 2019 (45%) and the 2018 (47%) have a lower engine and transmission complaint share than the 2021 (51%). Manufacturers fix things mid-generation, so the year before or after can be a different car.

Should I buy a 2021 BMW X5?

That depends on the car in front of you, not just the model year. The 2021 BMW X5 has an elevated transmission complaint pattern, so treat it as a car that needs proof: service records showing transmission work, a cold-start test drive, and an independent pre-purchase inspection focused on the transmission. A well-kept or already-repaired example can be a fine car; an unknown one is a gamble.
