Trims

NHTSA's VIN data lists these trims for the 2015 6 Series. A trim's engine and numbers are shown as its own only where EPA names versions after the trim and no other version could be it; "seen with" means a source shows that engine on the trim, not that it was the only one. Recalls and complaints cover the whole model year: whether a recall applies to a car depends on its VIN, on NHTSA's recall lookup.

Problems owners report

Owners have filed 9 complaints with NHTSA about the 2015 6 Series. 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 1 recall campaign for the 2015 6 Series 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 293 service bulletins and notices that cover the 2015 6 Series, the latest on Jan 21, 2026. They tell dealers how to fix known issues.

The parts they mention most: electrical system (109), equipment (103), engine (38), equipment adaptive/mobility (27), fuel system (22).

NHTSA defect investigations

Opening an investigation isn't a finding of a defect. Outcomes are as NHTSA's summary states them. A recall is shown as an investigation's outcome only where NHTSA's summary names it; other recalls NHTSA's file lists with it are marked as listed, not caused.

Maintenance

Oil

The owner's manual gives the oil and how often to change it. We show oil facts only once we've checked them against the manual, and we haven't yet for the 2015 6 Series.
