Owners have filed 59 complaints with NHTSA about the 2014 4 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.
NHTSA lists 6 recall campaigns for the 2014 4 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.
BMW of North America, LLC (BMW) is recalling certain 2014 4 Series Coupe (428i, 428i xDrive, 435i, 435i xDrive), 3 Series Sedan (320i, 320i xDrive, 328i, 328i xDrive, 335i, 335i xDrive), and 2014-2015 2 Series Coupe (228i, 228i xDrive, M235i, M235i xDrive) vehicles.
