2021 X5 M50i: The driver's knee airbag deployed in a crash and lacerated my left lower leg down to the muscle and abraded most of the layers of skin on my right shin. I was taken to the ER by ambulance. The laceration could only be partially sutured together. There was no shrapnel in the wounds. I have to go to a wound care center to treat the mentioned injuries. Everything else on me was fine, just some bruises and sore muscles; my car saved my life. I was not at fault. All airbags, except the vacant front passenger, were deployed. I was the only occupant of the vehicle. The airbags have not been inspected by the dealer or anyone else as it was a total loss and taken away to a salvage lot to be sold at auction. The insurance company went by the photos that I sent in. I have a lot of photos. There are knee airbag recalls on other model years of this vehicle but none on mine, the subject VIN. It has had no recalls since I owned it and I bought it new in Sept 2020. There were no warning indicators of any potential problems prior to the crash. I suspect the edges may be sharp or it didn't deploy properly. I hope these airbags can be checked to see if they are defective as they can really hurt someone. (There is a lot of insurance claim communications that I haven't attached but I will if requested)
