On and off system notification of "passenger restraint system malfunction" with and without a passenger in the seat. Also, the airbag off/disabled light on the instrument cluster illuminated. Can't seem to declare if it is an electrical shortage, seatbelt buckle related or passenger pressure sensor sensor in the seat. Find this to be a major safety concern should there be an accident, and unsure whether the airbags will deploy or not. BMW should investigate this concern.
Infotainment system interplay through audio voices coming from place of employment this have been unusual to audio system in various of my vehicles this over the air bugs are safety concerns as well as frequent unexpected wiper blade activation without touching for auto movement complex to electrical issues uncommon to vehicle routing infotainment system leading to unexpected interruptions sending false signals to vehicle electrical system causing many interruptions. Highlighting the growing complexity and potential risks associated with vehicle software. Implications, and solutions for these complex symptoms.
1) passenger restraint system malfunction. According to information on the web and several BMW forums, this is a common problem on these vehicles and it is a serious and inherently unsafe issue that should necessitate a recall from the manufacturer. The root cause is typically a malfunction of the passenger seat pad that is utilized by the passenger restraint system. BMW service repair cost is $2,700-$3,000. This is really outrageous given that it's part of the safety restraint system and many BMW 5 series (and likely others) have this problem.
The car's hood sensor did not alert us to the fact that the hood was not properly closed. This resulted in the car's hood opening while being driven, causing the driver to lose sight of the road and crashed into a guardrail in a canyon road (see photo). The car is currently being evaluated by the insurance company for a total loss, and the car may be available for inspection currently, although it may also be taken apart by the auto collision company for their estimate evaluation. The failure of the hood latch mechanism to properly and conspicuously notify us prior to driving the car put us at severe risk of being in a life threatening accident as well as potentially imperiling the lives of other drivers or pedestrians. The vehicle was inspected by BMW after I reported the incident to them, and I have a written report from them. BMW concluded they are "technically confident that no manufacturing defects, faults or malfunctions were present in the vehicle that could have contributed to this incident. " there were no warning messages of the problem prior to the hood opening. We also provided BMW with a video taken after the crash whereby the hood latch on the right side of the car was intentionally left open, and the hood latch on the left side of the car was closed, and demonstrated in this situation that there was no indication on the BMW I drive screen of any notifications to alert the driver of the hood not being completely closed. Despite asking numerous times for BMW to address the findings in that video, which we shared with them at their request, they never provided any response to the video. I would like to share the video with you but am unable to upload mp4 files onto your platform.
The vehicle was at a complete stop, when the gas pedal was tapped to move forward slightly the vehicle suddenly accelerated out of control. There was an attempt to apply the brakes, but the vehicle continued to accelerate and "drive train malfunction" began to flash on the dashboard of the vehicle. The vehicle proceeded to accelerate as it jumped a curb, crashed into a ditch, before finally becoming lodged in a fence and coming to a complete stop when half of the vehicle was lifted off of the ground. The driver of the vehicle suffered a fractured back as a result of the incident. We have reported this incident to BMW and are awaiting a response from the manufacturer. The vehicle has been inspected by the driver's insurance and, while we do not have a report from them yet, the vehicle was totaled.
