What owners report
Short excerpts of NHTSA complaints in the original wording. These are owner statements not verified by NHTSA; personal data removed.
Our M235I has a transmission leak "thru the wall of the case" (i.e. THROUGH THE METAL CASE) as determined by a local BMW Dealer. They are not able to provide any Technical Service Bulletins or etc. from BMW for this "leaky case" issue. But they are saying this is a KNOWN problem with the transmission cases.
BMW 2 series cars from about 2015-2018 have faulty wiring and brake light assemblies. BMW has admitted this design flaw in the harness and light - they extended the warranty for one year. As you know, brake light failures represent a real risk.
Summary: OVER TIME, RESISTANCE IN THE ELECTRICAL CONTACTS MAY CAUSE ONE OR MORE REAR LAMP FUNCTIONS (TAIL LIGHT, BRAKE LIGHT, AND/OR TURN-SIGNAL), WITHIN THE VEHICLE'S BODY PANEL, TO STOP WORKING. Consequence: INTERMITTENT LIGHT OPERATION REDUCES THE ABILITY TO WARN OTHER MOTORISTS OF THE DRIVER'S INTENTIONS.
Driver side seatbelt is slow to retract and keeps getting twisted when retracting. You have to carefully help feed the belt into the b pillar for it not to do that. If not, it will almost get jammed in the b pillar and get stuck and becomes non-functional.
Tl* the contact owns a 2016 bmw m235i. The contact stated that while operating the vehicle the odor of fuel was present. The vehicle was taken to an independent mechanic who diagnosed that the fuel tank had cracked and needed to be replaced. The cause of the damaged fuel tank was not determined.
There is no way to switch the instrument lights on at all times, even if the headlights are switched on.
The sunroof made a loud pop and shattered spontaneously, raining glass down on me. The glass had an outward bend to it as if it had exploded outwards with pressure relief.
