To: National Highway Traffic Safety Administration (NHTSA) Subject: Safety Complaint – 2018 BMW M550i Driver Assistance System I am filing a formal safety complaint regarding a dangerous malfunction of the driver assistance systems in my 2018 BMW M550i. These systems behave unpredictably and cannot be reliably disabled, creating an unsafe driving condition. The vehicle’s driver assistance featu...
I’m getting a passenger restraint system malfunction message on my infotainment. Says: “Passenger restraint system limited. Increased risk of injury in case of a collision. Continue wearing safety belt.” This is the second time this has occurred on this specific vehicle. First time was in 2021 and was repaired. Now it came up again.
Passenger restrain system mail function
Passenger restrained seatbelt signal. There is bulletin in google: SIB 72 04 17. There are recalls for this vehicle but dealer want accept it.
In the last 8 months, I have experienced 3 blowouts on the same side of the car. The tires were Continental Procontact SSR 245/40R19. In each instance, the sidewall failed and blew out. This has occurred on the highway as well as at low city speeds.
Excessive amounts of water accumulated at interior floors from the A/C drain unit. Water damage to all sensors and bad odor. Worried car may catch fire while driving. A/C will sometimes work.
The rear driver door does not open from the outside or inside of the vehicle. I had someone sitting behind the driver and they could not exit the vehicle, we had to assist so they can exit out the other side (passenger rear door). The handle on the outside of the car seems like if it is not connected to the door mechanism. This is a huge safety issue. I also took the car to the dealer to have ...
The rear driver door will not open. It seems the door handle does not open the door from the exterior of the vehicle. The door will also not open from the interior of the vehicle. It feels like the handle has come lose from the door latch mechanism to open the door of the vehicle. This is a big safety concern if there is a passenger sitting behind the driver and they cannot exit the vehicle.
Vehicle reported a Passenger Restraint Failure intermittently and upon getting diagnosed is related to a faulty seat occupancy sensor. If this sensor can fail ~4yrs of ownership with < 30k miles driven and it is critical to passenger restraint, it would seem that this should be fixed by BMW. With quick search, the problem doesn't seem isolated: [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM...
Passenger restraint system malfunction. I took it to the dealership and was told it will cost $3785.91 to replace the passenger seat mat. Looking online, this problem appears to be widespread with many individual car owners complaining of the issue. Given that this is a life safety system and its apparent prevalence, it seems appropriate to consider this for a mandatory recall.
The passenger seat occupancy mat is faulty - same as in many other BMW models for which BMW has issued a 15 year warranty. The car chimes and states "fasten safety belt" for the passenger seat when the passenger seat is entirely empty. This error comes and goes, and stops when the belt is buckled.
The passenger restraint malfunction continues to alarm and the dealership states that it is a seat-pad sensor and want over $2000.00 to replace. From a number of BMW forums, it appears that this was a common problem with earlier models and a subsequent 15-year warranty extension was granted because of the safety concerns. My car is well cared for and has very few miles on it, so I truly believe ...
Passenger Restraint Warning Light has been coming on off and on and now stays on all the time. Dealer has confirmed car needs to have the OC3 mat replaced at a very high price. Car is a 2018 BMW M550ix. Apparently this has been a common problem with the BMWs.
Passenger side sensor is faulty. BMW has issued Technical Service Bulletin to repair when found in warranty. The sensor will errantly warn airbag disable when person is not in seat.
My old 5 series 2017 had this same problem, now my 2018 m550i has the airbag problem. A warning light for no reason pops up saying “passenger restraint system malfunction” and turns off the passengers airbag, BMW will not fix it out of warranty and charges 3,000$. Many people are driving around without airbags in a new car because of this.
On vacation road trip driving for about 3 hours. Instrument cluster completely shuts off and goes to black. Screen, vehit speed and rpm and all adas systems stop working. Sometimes turning the car off and on will address the issue other times it will constantly restart the instrument cluster when driving.
Sunroof on 2018 BMW M550i "exploded" while driving home from work. Weather was cloudy, light rain in the 50's, late March in northern California, USA. Sunroof was in closed position and cars HVAC was not being used to create temperature or pressure difference. Heated seat was being used. Had been parked outdoors under an awning during the day and had been on the road for less than 15 minutes. The ...
I WAS DRIVING ON THE HIGHWAY AND THE SUNROOF EXPLODED OUT OF NO WHERE, BMW SAID A ROCK HIT IT OR SOMETHING BUT I AM 90% SURE A ROCK DIDN'T HIT IT. DID NOT SEE ANYTHING FLY UP TOWARDS THE CAR. IT SOUNDED LIKE A GUNSHOT WENT OFF IN THE CAR AND GLASS SHOWERING ALL OVER YOU BECAUSE I HAD THE SHADE OPEN. LUCKILY IT DID NOT GET INTO MY EYES TO CAUSE ANOTHER ACCIDENT. GLASS SHATTERED UPWARDS AND FROM DOI...
DUE TO WEATHER CHANGE THE SUNROOF CAN SHATTER. THIS COULD HAD INJURED TO PASSENGER AND INFANTS IN CAR. BMW TAKES NO RESPONSIBILITY ON FIXING IT
? THIS IS MY FOURTH CAR(BMW) BECAUSE I BIG FUN OF IT. HOPING FOR YOUR KIND CONSIDERATION. THANKS,
