BMW SIB 51 33 16 (NHTSA ID 10200233) Manufacturer defect resulting in water slowly backing up into trunk and other parts of car until it completely fills side panels, floor of car, ect. There is no indication this is occurring. There is no warning given by BMW dealer or manufacturer that this may become a problem resulting in costly repairs but more importantly health issues. Stagnant water not visible causes mold in the trunk and cabin and as well as behind hard surfaces. Stagnant water increases the humidity in cabin that begins the corrosion of all electrical components in car which can become dangerous. Failure of digital display including speed, gearshift and all safety warnings without warning to driver.

Crash reported3 injuries reported
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.
