The front differential and rear drive train has been problematic and has failed in model years starting 2019. My car is a April 2020 car with 34,000 miles and has already failed. There are numerous cars that share the same V8 engine and drive train, has similar front differential failures at very low mileage. BMW USA seems to not car and address the issue after it being brought to their attention.
TL* THE CONTACT OWNS A 2020 BMW M550I. THE CONTACT STATED THAT WHILE SLOWING DOWN TO STOP, THE AUTO STOP FUEL SAVING SYSTEM SUDDENLY ACTIVATED CAUSING THE VEHICLE TO ABRUPTLY STOP. THE VEHICLE WAS TAKEN TO THE LOCAL DEALER WEST HERR BMW LOCATED AT 4250 W HENRIETTA RD, ROCHESTER, NY 14623 WHO WAS UNABLE TO DETERMINE THE CAUSE OF THE FAILURE. NO FAILURE WAS FOUND WITH THE VEHICLE. THE MANUFACTURER WAS ALSO NOTIFIED OF THE FAILURE. THE FAILURE MILEAGE WAS 3,000. THE VIN WAS INVALID.
The guibo (flex disc) in the powertrain has multiple visible cracks, posing a safety risk due to its potential to disrupt power transmission to the wheels. This malfunction could impact vehicle control, particularly at higher speeds, thus putting passengers and other road users at risk. A certified BMW service center has confirmed the problem, with BMW technicians recommending a replacement; however, both the dealer and BMW have declined to cover it under warranty. Although there were no warning lamps prior to the failure, slight vibrations or noises may have indicated an issue with the guibo. The attached image is the recommendation from the BMW service center however I declined to it repaired out of pocket.
I have had two separate incidents of cracked wheels. I drive the vehicle on normal roadways and have had no impacts with curbs, debris or significant road hazards. The wheels show no signs of any impact or damage, just a crack. Of course the cracked wheels result in a rapid loss of tire pressure. BMW will not warranty the wheels and replacement of each has cost me $800. I feel the wheels were obviously not engineered properly to withstand the load and forces of normal highway driving. The First cracked wheel was in November of 2023 - right front. The most recent was August 2024, left rear. The vehicle had approx 30,000 miles at the first incident and most recently 38,000 miles for the second incident.
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 features (including steering and braking interventions) activate or restrict themselves unexpectedly while driving, sometimes without clear warnings. At other times, the system disables itself mid-drive. Despite repeated attempts, these features cannot be fully turned off, leaving me forced to rely on a computer system that makes erratic decisions affecting vehicle control. BMW dealerships acknowledge the issue but state no permanent fix exists unless I pay out of pocket. BMW corporate has declined goodwill repairs and claims the behavior is “normal,” despite the clear safety implications. I believe I should not be required to pay to correct a defect that impacts safe operation of the vehicle. This issue is especially concerning given prior BMW recalls involving driver assistance and steering sensor systems. An unpredictable or uncontrollable ADAS system undermines driver authority and increases crash risk. I am requesting that NHTSA investigate this issue to determine whether it represents a broader safety defect and require BMW to provide a full repair at no cost. If the defect cannot be reliably repaired, I believe a buyback or vehicle replacement should be considered. This vehicle does not operate in a consistently safe manner, and I fear continued use places me and others at risk. Thank you for your attention to this serious safety concern.
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 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.
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 door covered under my extended warranty and they did not cover it under warranty.
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 OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
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 $2000.00 to replace. From a number of BMW forums, it appears that this was a common problem with earlier models and a subsequent 15-year warranty extension was granted because of the safety concerns. My car is well cared for and has very few miles on it, so I truly believe that BMW needs to either recall this faulty SAFETY component or replace it free of charge. Please protect me and my family by holding BMW accountable.
Passenger Restraint Warning Light has been coming on off and on and now stays on all the time. Dealer has confirmed car needs to have the OC3 mat replaced at a very high price. Car is a 2018 BMW M550ix. Apparently this has been a common problem with the BMWs.
Passenger side sensor is faulty. BMW has issued Technical Service Bulletin to repair when found in warranty. The sensor will errantly warn airbag disable when person is not in seat.
My old 5 series 2017 had this same problem, now my 2018 m550i has the airbag problem. A warning light for no reason pops up saying “passenger restraint system malfunction” and turns off the passengers airbag, BMW will not fix it out of warranty and charges 3,000$. 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.

📖 Understanding This Data
What is an NHTSA Complaint?
An NHTSA safety complaint is a report filed directly by a vehicle owner or driver describing a safety-related issue. Anyone can submit a complaint at NHTSA.gov. The number of complaints is a signal of how common a problem is — but complaints per model-year matter more than raw totals, since popular vehicles naturally receive more reports. The BMW M550i has 26 complaints on record across 6 model years.
What is a Safety Recall?
A safety recall is a mandatory campaign issued by NHTSA when a vehicle component poses an unreasonable risk to safety or does not comply with federal motor vehicle safety standards. Unlike complaints (which are owner-reported), recalls are formally investigated and confirmed by regulators. Manufacturers must fix recalled vehicles free of charge. The BMW M550i has 7 recall campaigns in the NHTSA database.
What Are Crash Complaints?
Crash complaints are NHTSA filings where the owner indicates a crash occurred as part of the incident. 0 of the BMW M550i's 26 complaints involved a crash. This metric is particularly important because it indicates how often defects resulted in actual collisions — a key safety signal beyond general reliability.
How Is the Reliability Verdict Calculated?
The reliability verdict (Average) is generated by analyzing the vehicle's total complaints, recall history, crash complaint ratio, fire complaint ratio, and top component failures relative to class averages. This verdict gives buyers a quick interpretation before they review year-level details and VIN-level history. It should be treated as one decision input, not a substitute for a VIN-specific report.
Why Do Newer Years Have Fewer Complaints?
Newer model years appear to have fewer complaints because there has been less time for owners to file them. Complaints accumulate over years of ownership. A 2020 model year vehicle will typically show fewer complaints than a 2015 model year even if it is less reliable — simply because fewer owners have had time to report issues. Focus on complaints per year of market presence when comparing across model years.
Fleet Data vs. Individual VIN
Everything on this page reflects aggregated data across all BMW M550i vehicles on the road — not any specific car. Two BMW M550i vehicles of the same year can have very different histories: one may have been in three accidents and have an open recall; another may be clean. A VIN check gives you the individual car's history: accidents, title brands, odometer records, service history, and real-time recall status.
What Are NHTSA Investigations?
When NHTSA receives a pattern of related safety complaints, it opens a formal investigation. A Preliminary Evaluation (PE) is the first stage — NHTSA determines if a safety defect may exist. If evidence is strong, it escalates to an Engineering Analysis (EA), which can result in a mandatory recall. The BMW M550i has 0 investigations on record (0 active). Investigations listed above may have already led to the recalls shown on this page.
