What 2018 BMW 530i owners say
Air bags
Passenger restrain system malfunction where airbags will not deploy if car is in accident. this seems as an issue with BMWs and they had recall before on certain models and years, dealers do not want to process claims under manufacturing warranty to fix an issue even the car is still under manufacturing warranty. claiming that water could have been spilled seems very convenient not to fix this issues. i took my car to dealer and they ran diagnostic test and charge me $200 to tell me to turn heat in the seat because moisture, sound unfair. week after that same message came on i am not sure how it is legal for BMW dealers to clear code and send people home and tell them to turn heat in the seat and hopefully problem goes away. which it did not and there should be recall for this issue especially if airbags are concern.
I recently took my vehicle in for a service due to "passenger system restraint" error code. Upon dealer inspection it would cost upwards of 4,000$ to fix this issue. I called my warranty company and they do not warranty any repairs that have to do with restraint systems. This seems to be a widespread issue from what I have read. This can really cause a major issue if the seatbelt for the passenger side does not work upon a collision. This has to be putting people in a serious situation and should be investigated. Thanks for your time.

Passenger Restraint System Malfunction. This is what randomly and constantly pops up. The fasten seat alert goes off the whole time I'm riding, although no one is in the passenger seat. I took it to the BMW service center twice and each time they keep my vehicles for hours, just to say they couldn't duplicate the issue.
