Which vehicles
A recall reaches a range of VINs inside these model years, not every car built in them. Yours may not be covered even if it is listed here, and the only way to find out is NHTSA's own VIN lookup .
How this campaign compares
At 50,024 vehicles this is a bigger campaign than 89% of the 19,818 vehicle recalls filed since 1995 whose size NHTSA published. The middle campaign on file covers 472. It covers model years 2019 to 2021, so the oldest vehicles on it were 2 model years old when the defect was reported to NHTSA.
BMW vehicles have been recalled over the engine 2 times before this, most recently in October 2019 as 19V732000. That is not evidence the earlier repair failed.
This site holds the complaint record for 8 of the 12 model years the campaign names. Their owners have filed 226 complaints with NHTSA, 32 of them before this campaign was filed. 77 of those name the engine, the system this recall is about — a count of complaints, not of this defect. The earliest of them reached NHTSA in September 2019, 1 year before this filing.
The vehicles on this campaign carry 22 other recalls published here, the newest being: 26V438000 (electrical system), 26V056000 (electrical system), 25V636000 (electrical system), 24V764000 (structure).
Check your own car
A VIN check is the only answer for a specific vehicle, and it also shows every other open recall on it, which is usually the reason it is worth doing rather than reading one campaign.
Filed by BMW of North America, LLC with NHTSA on August 2, 2021 as campaign 21V598000. Every word of the defect, consequence and remedy above is NHTSA's published record of that filing, not a summary of it.
