2024 BMW X3

I am reporting a serious safety issue involving my 2024 BMW X3 purchased from Countryside Mitsubishi in Countryside, Illinois, on November 7, 2025. Within hours of purchase, I discovered multiple defects that were not disclosed before the sale. The most concerning issue involves the windshield wiper system and forward sensor components, which began to malfunction immediately. The vehicle’s onboard system initially flagged a windshield sensor fault. I later discovered that the original BMW windshield had been replaced with a non-OEM part, which BMW confirmed voided the vehicle's factory warranty and disabled key safety features dependent on OEM calibration. I was never informed of the windshield replacement at time of sale. When I raised concerns with the dealership, they admitted to using a sensor “workaround” instead of a proper replacement, which BMW later explained is not compliant with their specifications and leaves the vehicle’s advanced safety systems—such as forward collision alerts—compromised. The dealership falsely stated the repair was done by BMW-certified technicians, which was later denied by the repair staff. This defect creates a major visibility and safety hazard. I experienced intermittent wiper failure during poor weather, and the washer fluid system also failed to operate reliably. Despite repeated contacts, the dealership refused to install an OEM windshield or resolve the defect through an authorized BMW service provider. BMW has confirmed that their safety systems will not function correctly unless an OEM windshield and correct calibration process are used. This places me and others at serious risk during adverse weather or emergency braking situations. I have full documentation, a repair timeline, videos of the malfunction, and correspondence with the dealership. The vehicle is still in my possession and available for inspection upon request. I urge NHTSA to investigate this case for potential noncompliance and safety risk.
