“2018 Bmw X3 m40i: upon start up the vehicle displays a warning 'seatbelt restraint system malfunction.' the car the enters a limp mode and says to drive to the nearest Bmw service center and that some safety features are unavailable.

What's disturbing is that I discovered that many other late model Bmw owners are reporting this same issue. …”
NHTSA complaint #11150446, filed 2018-11, 2,000 miles“For about 1 year now when there is someone in the passenger seat the car will randomly stop recognizing the seat is occupied and deactivate the air bags on the passenger side front.
