The doors on our bmx 330xi will lock and we cannot unlock them from the inside or the outside using the interior or exterior door handles or the key fob. My wife and kids had to climb out of the windows to get out of the vehicle. If there was an accident they would have been trapped. I called the BMW dealer and they told me to have it towed and they would take a look at it. This has happened several times and it is an extreme safety issue. I have researched it and it appears to be a very common problem on the 300 series. It has happened a few times and then the problem goes away. I hope no one gets hurt because they get trapped in their vehicle. Thank god that my family was physically able to climb out of the windows, if they were elderly or disabled they would have been trapped. This is an extremely dangerous safety defect that needs to be investigated, addressed and remedied by the manufacturer.

Doors fail to unlock, either using the keyfob, the inside button or manually by pulling the door handle. This is a very dangerous situation as occupants are trapped inside. No method of opening the door work. This appears to be intermittent and eventually the doors unlock mechanism starts working again. The GM5 module seems at fault. This could be very dangerous in an emergency situation.

Passenger side door and both rear doors failed to open. All three doors remained locked and could not be open from inside by using the mechanical handles. Neither the remote key nor the regular key was able to unlock the doors.

In 2010 the sunroof went bad I talked to a BMW dealer and they told me they have problems with them, in August of 2011 I noticed that my tail lights and blinkers were not working proper, nor was my horn, and the drivers window regulators are binding up, also a brake hose from my brake booster to the engine is collapsed in two spots. ??

Intermittent failure of driver and passenger side tail light assembly due to burnt connector pins and connector housing. Inadequate connector/wire rating. Should be subject of a recall from a responsible car manufacturer. Unsafe to drive in the dark. Blemish on the ultimate driving machine. Intermittent failure of the mostly passenger side head light. Occasional failure of the driver side head light. Normally the light bulb would require replacement, but often the whole lighting unit is considered failing by the dealer. Cost of replacement is extremely high.

The passenger doors fail to open with the internal door unlock button. This is due to failure of door unlock relays in the GM5 module. This could result in a significant safety issue if a failure of the unlock relay happens when attempting to unlock passenger doors in an emergency to retrieve passengers.

My car will not unlock reliably via the remote control or the center unlock/lock button. I can't get into the car when this problem happens. The general module(GM5) is going bad and the car will only unlock when it feels like it. From what I understand this is a normal issue with my 2003 BMW 330I. Hopefully BMW will file a recall on this item so I don't have to pay the $790 the dealership charges for this known problem.
