I owned a 2020 BMW 430i (VIN: [XXX] ) manufactured in March 2019 at the Regensburg plant. This vehicle matches the exact criteria of NHTSA Recall 19V-352 for defective knee airbags that may fail to deploy in an accident. I was involved in a serious crash on [XXX], and the airbags did not deploy. Despite this, my VIN is not showing as included in the recall. I am submitting this as a potential VIN exclusion error that may have resulted in harm and needs urgent investigation. I have documentation of the vehicle's production date, model match, and accident details. I also suffered significant psychological trauma as a result of this failure, which escalated due to the lack of explanation at the time.
