The seatbelt/passenger seat fails to recognize a passenger is occupying the seat and turns off the airbag. This issue has been reported many times to BMW and on vehicle forums. This is an expensive fix ($2800) that should be issued a recall by the manufacture and not passed onto the owner of the car.

Constantly pops up a message for passenger restraint system malfunction. I had an accident where I swerved off the road into a ditch at about 60 mph. I the driver was not hurt and the passenger wouldn’t have been hurt either if it was for the passenger seat belt not locking correctly at first and then repeatedly locking and unlocking the entire time hurting his chest.

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.

MY CAR HAD UNDER 17,000 MILES AND HAD BEEN SERVICED ON SCHEDULE BY AN AUTHORIZED DEALER. I HAD BMW ANCHORED DRIVER'S FLOOR MAT IN PLACE. MY MOTHER-IN-LAW AND I WERE WEARING OUR SAFETY BELTS. WE WERE APPROACHING A FOUR-WAY INTERSECTION WITH A TRAFFIC LIGHT. THE SPEED LIMIT ON THE ROAD IS 35 MILES AN HOUR. I WAS DRIVING SLOWER THAN THAT SPEED. AS I WAS APPROACHING THE INTERSECTION WITH A RED LIGHT , I HAD TAKEN MY FOOT OFF THE ACCELERATOR. ALTHOUGH MY FOOT WAS NOT ON ANY PEDAL, THE CAR SUDDENLY ACCELERATED. I HIT THE BRAKES BUT I COULD NOT SLOW THE CAR. I WAS RAPIDLY APPROACHING THE INTERSECTION AND OTHER VEHICLES. TO THE RIGHT OF THE ROAD WAS A HOUSE. I STEERED THE CAR OFF THE ROAD AND INTO THE FIELD ON THE LEFT. I AM CERTAIN THAT MY FOOT WAS ON THE BRAKE PEDAL BECAUSE OF ITS POSITION AND RESISTANCE. THE CAR HAD ACCELERATED WITHOUT MY FOOT ON ANY PEDAL. DUE THE CAR'S SPEED AND AN INCLINE AT THE ENTRANCE TO THE FIELD, THE CAR BECAME AIRBORNE FOR A SHORT DISTANCE BEFORE LANDING HARD AND CONTINUING TOWARD A DUMPSTER. ALTHOUGH I WAS UNABLE TO SLOW THE CAR, I WAS ABLE TO STEER THE CAR AWAY FROM THE DUMPSTER AND TOWARD A STEEP HILL AT THE END OF THE FIELD. THE CAR WAS SLOWED BY THE INCLINE AND CONTACT WITH THE GROUND. MY FOOT WAS STILL ON THE BRAKE PEDAL. I WAS ABLE TO PLACE THE CAR IN NEUTRAL. I PLACED THE CAR IN PARK AND TURNED OFF THE IGNITION. I CALLED 911. THE AIRBAGS DID NOT DEPLOY. MY HUSBAND AND THE POLICE OFFICER BOTH CONFIRMED THAT THERE WAS NOTHING IMPINGING UPON THE ACCELERATOR PEDAL. MY MOTHER-IN-LAW WAS TRANSPORTED BY AMBULANCE TO THE HOSPITAL WHERE SHE WAS ADMITTED FOR ACUTE LUMBAR SPINAL COMPRESSION FRACTURE. I WAS EVALUATED IN THE ED AND RELEASED. BMW IS TO SEND AN ENGINEER FROM BMW TO EVALUATE MY CAR. THE BODY SHOP TOLD MY HUSBAND THAT AN EMPLOYEE STARTED MY CAR WHICH INITIALLY REVVED AT A HIGH RATE. UNINTENTIONAL ACCELERATION

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 2018 BMW 5 Series Hybrid Sedan Phev verdict →
