Passenger restraint system malfunction. My vehicle as well as thousands of others have the chronic and unsafe issue of the passenger occupancy sensor malfunctioning. In order to remove warning on dash it’s either a $2,000 repair, or a $40 bypass which basically places the seat as constantly occupied, sticking the passenger airbag in the ‘on’ position. Vehicle is available for inspection. With this malfunction, any person that sits in the passenger front seat is at risk of injury or death in the event of a collision. Malfunction has been confirmed by both a dealer and an independent service center. Vehicle was inspected by the dealer, but no police or insurance company. Vehicle was purchased with the malfunction and the warning lights have been on for several years. With the massive number of vehicles of this make with a range of different mileage, with this issue, a recall is not only needed but warranted and should be mandated with this being a major safety issue.

PE13030 · Loss Of Power Assist Braking

Opened Sep 6, 2013 · Closed Oct 25, 2013

Status: closed (inferred from source dates) · Service Brakes, Hydraulic:power Assist:vacuum

In a letter dated September 26, 2013, BMW Group submitted a safety recall notice to NHTSA identifying a defect condition in the vacuum pump oil supply that may result in loss of power assist braking in 76,191 model year (MY) 2012 through 2014 BMW 3-Series, 5-Series, X1 SAV, X3 SAV, and Z4 vehicles equipped with 4-cylinder engines (NHTSA Recall 13V-454).According to BMW, movement of the seal disk within the camshaft may result in blocking of the oil supply to the vacuum pump, resulting in improper pump operation and loss of power assist braking.On July 11, 2013, BMW initiated a change to the camshaft geometry that prevented the seal disk from blocking the oil port.BMW has not received any braking complaints related to loss of power assist after the design change was implemented in production.The owners of all affected vehicles will be contacted by mail and asked to take their vehicle to a BMW dealer who will install a locking ring into the camshaft to keep the seal disk in its proper location.BMW expects to begin dealer and owner notification in November 2013 and complete dealer and owner notification in December when the remedy is expected to be available.Based on the actions taken by BMW, this investigation is closed.
