1 Seat Belt problem of the 2013 BMW 335

Failure Date: 06/24/2023

Out of nowhere, on 6/24, the warning light came on saying that there is an issue with the passenger restraint system. It stays on when there is no one in the seat and then, even if someone is in the seat, it will turn off. I have not had an accident or had the car flooded to warrant a system malfunction like that. I have read that this has happened to other owners of this model and it is a faulty mat sensor that costs over $1000 to repair.

2 Seat Belt problem of the 2009 BMW 335

Failure Date: 10/27/2022

My car randomly started throwing an error for a failure with the passenger restraint system. From what I have read it has something to do with the oc3 mat in the seat that detects if there is an occupant, and if the weight of the occupant is considered to be that of an adult, so the airbag does not deploy in the wrong circumstances, which is potentially dangerous to anyone that may ride in the passenger seat. There has been an extended warranty, and recall for previous years of e90 Bmws, but 2009 may not be included, even though the seats should be the same. I plan on contacting the dealership for further investigation, but I know I cannot afford to have this safety feature fixed out of my pocket at this time. Thank you for your time.

6 Seat Belt problem of the 2009 BMW 335

7 Seat Belt problem of the 2011 BMW 335

Failure Date: 12/18/2019

The front passenger seatbelt sensor malfunctions and sets off the warning sound as if someone is siting in the seat when nobody or nothing is in the seat. This may cause airbag malfunctions or have it not deploy. This has been happening since the first day I bought the car several weeks ago. The issue is constant while I'm driving.

8 Seat Belt problem of the 2013 BMW 335

Failure Date: 05/01/2019

My vehicle shows the following error message "passenger restraint malfunction" at random times while I am driving without a passenger or whenever a passenger decides to move around. The error will also appear at random times whenever I have a passenger. I ran obd reading and it gave the error code "930a1c-ods-system: seat occupancy sensor passenger: sending sensor failure because of wetness ,0, zp. " I have never spilled liquid matter on the seats and I live in a dry desert environment where temperatures range from 80 to 110 degrees fahrenheit. The BMW dealership in palm springs told me I will need to replace the passenger mat, but my warranty will not cover it. I was quoted to pay $1600 out of pocket just to fix a faulty sensor mat that is essential in protecting a passenger's life in the event of an accident. I am afraid the airbags will not work properly in the event of an accident and the airbag deployment can be lethal to a child passenger or an elderly adult. I can not find a local mechanic who can replace the passenger mat, nor can I buy the part online for my model. It is a bit injustice for me to pay a large amount of money to fix a defective part made by BMW and have no other choice other than to take it to the BMW dealership. Just to have them inspect my vehicle costed $175. I have also been made aware that BMW recalled 76,565 vehicles due to a defect in the front passenger seat occupant detection mat for BMW models 2006 325i, 325xi, 330i and 330xi sedans and 325xi sport wagons, the 2007 328i, 328xi, 335i and 335xi sedans and 328i and 328xi sport wagons, the 2006-7 525i, 525xi, 530i, 530xi and 550i sedans and 530xi sport wagons, the 2006 760i sedans, the 2006-7 750i, 750li, and 760li sedans and the 2006 x5 sport utility vehicles. It seems these defects were found in my 2013 model and I will like BMW to address this issue and fix it.

9 Seat Belt problem of the 2009 BMW 335

Failure Date: 03/05/2019

11 Seat Belt problem of the 2013 BMW 335

Failure Date: 04/25/2017

I was rear ended from a dead stop by a vehichle around 50 mph and my airbags malfunctioned. I had smoke coming from the dash but no actual air bag protected me by coming out. The seat belts are locked up and no longer work. The car then forced me to leave it in the middle of the road because it does not allow you to push it or put it into neutral in any fashion. This also forced it to be harmful to the vehicle to be put onto the tow truck because all wheels were locked up.
