today we got into my car and when i turns the car on the heads up unit displayed sayin passenger restraint failure, it said something about the seat belt or tension had affected the airbag. does anyone kno wat this means???????? and do you knoe how much it cost to fix? has anyone had this problem before?

 

If you still have warranty, it's covered. The common problem is the mat sensor under front seat is broken/damaged. It might just a software reset or mat sensor replacement which will be very pricy $500+.
Please update your profile to let us know where you are and what car option you have under your signature.
You might be from India.

 

I had the same issue, turned out to be my passenger sensor mat in the passenger seat. It was replaced under warranty.
