Three problems related to body have been reported for the 2015 BMW 335. The most recently reported issues are listed below.
Driver passenger door would not open when the car is locked from inside. Typically the driver can double pull the door handle which unlocks the car. When attempting to unlock, the pin goes up but comes back down. There are several documented complaints on BMW forums with many owners experiencing this safety issue. If a driver gets into an accident or if the battery dies, the door may fail to open at critical moments. A recall is needed for this safety defect.
Driver and passenger door lock intermittently fails to open after being driven by pulling on the door handle twice. Only remedy is to use the central locking/unlocking switch on the dash to open the door.
Passengers door failed to open. Has a two pull mechanism, first pull of the handle unlocks the door and second pull opens the door. Door would not open on second pull from the inside or outside. My wife was essentially stuck in the car. This is a severe safety issue in the event of an accident or other. This needs to be fixed by BMW permanently because many other people have reported this issue and have had the mechanism replaced only to have it happen again less than a year later. All this happening on cars less than 4 years old and less than 30k miles. I have never had a door lock issue on any car until now.
