What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2016 BMW M235I, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Each component in detail
What the reports in each category say, in the owners' own words
Exterior lighting
Reports naming headlights, tail lights, turn signals and other exterior lighting.
From owner reports, verbatim
Rear brake light failure due to faulty wiring. Identical to the details located in this article (https://www.autoblog.com/2011/09/01/bmw-recalling-241-000-3-series-models-over-faulty-tail-lights/) for which the NHTSA had issued a recall for older BMW models in the past. This issue is common and wide-spread amongst bmw models produced between 2014 - mid 2016. After which BMW modified the wiring harness for the brake lights to fix the electrical shorting failures. This failure renders the entire housing inoperable - Brake light, turn signal and reverse lamp. 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. THIS COULD CAUSE A VEHICLE CRASH WITHOUT WARNING. I have attached a BMW TSB (SI_B63_05_17) which outlines that BMW was aware of this issue as early as October 2017 but did not issue a voluntary recall for an issue that warranted a recall in the past. My brake light housing failed as a result of the faulty ground wire 8 months after the extended warranty on these parts lapsed resulting in an estimated $1140 in repairs for a critical safety component for which I cannot operate the vehicle safely without. The vehicle is currently with a BMW dealership for inspection and repair. Warning messages appeared after the component had completely failed while driving. Incident occurred in early August 2021.
THE CAR HAS INSTRUMENTS (SPEEDOMETER AND TACH) WITH LOW CONTRAST BETWEEN THE BACKGROUND AND LETTERING. THE INSTRUMENTS ARE HIGHLY VISIBLE WHEN THE INSTRUMENT LIGHTING IS ENABLED, BUT ARE NEARLY INVISIBLE WHEN THE LIGHTING IS OFF. THERE IS AN AMBIENT LIGHT SENSOR THAT TURNS THE INSTRUMENT LIGHTING ON AND OFF AS YOU DRIVE IN MIXED SUN AND SHADE, SO AS YOU DRIVE FROM A SHADED AREA TO A SUN-LIT AREA, THE INSTRUMENTS ALTERNATE BETWEEN VISIBLE AND INVISIBLE. IT IS DISCONCERTING AND DANGEROUS TO SUDDENLY LOSE INSTRUMENT VISIBILITY AS YOU DRIVE. THERE IS NO WAY TO SWITCH THE INSTRUMENT LIGHTS ON AT ALL TIMES, EVEN IF THE HEADLIGHTS ARE SWITCHED ON.

Electrical
Reports naming the electrical system — wiring, battery, charging, control modules, infotainment and electrical accessories.
From owner reports, verbatim
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. It is unreasonable for BMW to charge $900 per light to fix a safety issue caused by a design flaw that they have admitted. THE CONSUMER STATED THE PASSENGER TAIL LIGHT HAS FAILED, ALSO.

Powertrain (other)
Powertrain reports that are not specifically the engine or transmission — driveshafts, axles, transfer cases and differentials.
From owner reports, verbatim
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. They are advising a new transmission for $10K. Only alternative is to install used transmission and take old electronic valve module out of existing trans and place into used transmission and hope for the best. Loss of transmission fluid could cause unit to malfunction or fail!!!

Seat belts
Reports naming seat belts, buckles, retractors and pretensioners.
From owner reports, verbatim
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. IT TAKES A LOT OF STRENGTH AND EFFORT TO PULL TO PULL IT BACK OUT. VERY UNSAFE BECAUSE YOU HAVE TO BE ALWAYS AWARE OF THIS DEFECT WHILE DRIVING. SOMETIMES WE HAVE TO UNFASTEN OUR BELTS WHILE DRIVING TO REACH OR ADJUST SOMETHING. AND IT USUALLY GETS JAMMED AND STUCK IN THE B PILLAR AND BECOMES NON-FUNCTIONAL. OWNED AND DRIVEN SEVERAL CARS. THIS HAS NEVER HAPPENED BEFORE WITH ANY OTHER CAR. NEVER WITH THIS REGULARITY.

Visibility
Reports naming windshields, glass, wipers, defrosters and mirrors.
From owner reports, verbatim
WAS TRAVELING AT 55 MPH ON AN EXIT RAMP WITH THE NEAREST CAR ABOUT 5 OR 6 CAR LENGTHS IN FRONT OF ME. SMOOTH, PAVED ROAD WITH NO DEBRIS. 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. NO ROCKS OR DEBRIS WERE SEEN OR POSSIBLE FROM NEARBY VEHICLES GIVEN THE DISTANCES BETWEEN MY CAR AND THEIRS, AND NOTHING BEING SEEN TRAVELING THROUGH THE AIR. IT APPEARS THAT THIS IS DUE TO A FLAW IN THE CONSTRUCTION OF THE GLASS ITSELF (I.E. FLAWS IN CONSTRUCTION, IMPURITIES, ETC.), AND THAT THE SPONTANEOUS EXPLOSION OF THE GLASS WITHIN THE SUNROOF FRAME WAS NOT A RESULT OF ANY KIND OF IMPACT. THE GLASS WAS ALSO FLAWLESS IN TERMS OF NEVER HAVING BEEN NICKED BY DEBRIS. THE CAR IS A FEW MONTHS OLD WITH 3,000 MILES.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
