Electrical system
2 reports1 crash
“Exposed junction box in engine bay as well as water leaking through yellow grommet destroying footwell electronics as well as shorting junction box in engine bay. Water ingress also leaking into glove box electrical fuses and components. Also water leaking into trunk shorting out telemetrics battery as well as fuses of passenger side trunk fuse box. My ac compressor also blew simultaneously. There’s an active TSB for other models facing the same issue and should also cover this model as well.”

Engine and engine cooling
1 report
“The contact owns a 2015 BMW 650I. The contact stated that while the vehicle was at a red light, the vehicle accelerated and then lost motive power. There was no warning prior to the failure; however, the engine light illuminated immediately after the vehicle stalled, and the contact was able to coast to safety. The vehicle was towed to a dealer, where it was diagnosed and determined that the engine had seized. The contact was informed that the engine needed to be replaced. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was 140,000.”
Structure
1 report
“The car is leaking from the third rear brake light (at the rear roof of the car). It appears the seals and possible clips/fasteners have failed and water is entering the car during rain or water immersion from the rear brake light, to the back seat, trunk, and rear floor. There is now visible mold in the car.”
