There are 3 owner-reported body & structure complaints for the 2016 BMW 3 Seriesin NHTSA's database. These are unverified consumer reports and may not reflect confirmed defects.
While replacing the battery, the battery well was rusty. If allowed to continue I have no doubt the very heavy battery will fall through to the ground causing an accident and very hazardous materials will spill on the roadway (acids and lead from a ruptured battery).
Sunroof exploded while driving on the highway
WHILE THE VEHICLE WAS BEING DRIVEN ABOUT 40 MPH, I HEARD WHAT SOUNDED LIKE A GUNSHOT OR A LOUD POP OVERHEAD. I PULLED OVER TO SEE WHAT HAPPENED AND THE SUNROOF HAD A HOLE IN THE MIDDLE AND THE GLASS WAS BOWING UPWARDS. THERE WERE NO OTHER CARS PASSING ME AT THE TIME AND I DID NOT SEE ANY PROJECTILES COMING TOWARD THE CAR THAT COULD HAVE CAUSED THE DAMAGE. THE SUNROOF JUST SPONTANEOUSLY SHATTERED.
