Intermittent, but frequent failure of seat occupancy sensor on front passenger seat. Appears to be related to occupancy weight sensor. As sensor is not functioning properly, passenger airbag is being unsafely deactivated, leading to lack of airbag deployment if a front end collision were to occur. Problem is reproducible, but has not been taken to dealer, nor has it been inspected. Warning alert displays, then turns off, then returns frequently while the front passenger seat is occupied.

I continue to get airbag warning light and front passenger seat occupant detection malfunction. I was told by local mechanic that ACSM fault codes are 930A60 and 930A1C.

Problem is that the display says "passenger restraint malfunction" -- which brings safety concern. Upon online search, it is likely caused by design flaw of passenger occupancy detector. Here are some reasons why it is design flaw (i.e. not just individual failure) 1. There has been a recall for the same problem for earlier year models (2006-2007 etc). It seems the other years have the same problem (previous recall wasn't a complete fix) 2. There is actually a third party electrical device online that bypass passenger occupancy detector (so that the car thinks passenger seat is occupied all the time) -- which indicates the commonality of the problem because it even became a profitable market.

DRIVERS FRONT SEAT ACTIVE HEAD RESTRAINT DEPLOYED. FAULT CODE 930958 STORED. GENERATOR FOR ACTIVE HEAD RESTRAINT NEEDS TO BE REPLACED. VEHICLE WAS IN GARAGE, WHEN STARTED THE ERROR WAS DISPLAYED AND IS DISPLAYED EVER TIME THE VEHICLE IS STARTED. THIS EXACT PART WAS RECALLED ON MY 2013 328I AUTO. IT SHOULD BE RECALLED ON THE 2015 X3 AS IT IS THE SAME PART AND IS DEFECTIVE. THANKS

CONSTANTLY CHIMES WHILE DRIVING.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2015 BMW X3 Xdrive35i verdict →
