Problems owners report

Owners have filed 48 complaints with NHTSA about the 2018 M. These are unverified owner reports, counted by the part of the car they name; one complaint can name several parts. Counts aren't adjusted for how many were sold, so they don't show how reliable a car is.

Complaints by model year

Newer years have had less time to collect complaints, and counts aren't adjusted for sales, so a shorter bar doesn't mean a more reliable year.

Recalls

NHTSA lists 6 recall campaigns for the 2018 M over its history. Campaigns are matched by model and year, so each one may apply to a given car, and its repair may already be done: check a VIN on NHTSA's recall lookup for the open recalls on that exact car.

Service bulletins and investigations

Carmakers sent NHTSA 474 service bulletins and notices that cover the 2018 M, the latest on Sep 3, 2026. They tell dealers how to fix known issues.

The parts they mention most: equipment (172), electrical system (166), engine and engine cooling (44), equipment adaptive/mobility (40), engine (30).
