2018 BMW M550I — Problems, Recalls & Safety Data

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.
