NHTSA Complaint #11642974 — 2019 BMW X3

I am writing regarding my 2019 BMW X3 which has suffered catastrophic electrical damage due to premature sunroof seal shrinkage. The failure has resulted in: Damage to the amplifier Damage to the auto system Non-functioning park assist warning tones and signal Integrity of panoramic sunroof stability The dealership has identified seal failure as the root cause. This is particularly concerning given that: These seals are designed and expected to last 20 years This is a documented issue affecting multiple BMW vehicles My vehicle is only 5 years old, far short of the expected seal lifespan The premature seal failure clearly indicates a manufacturing defect, not normal wear and Tear. The systemic nature of this defect which Causes a significant gap between actual and expected seal performance The extensive consequential damage caused by this manufacturing issue Is highly concerning snd should be immediately investigated and addressed.
