Complaints on fileComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

I discovered suspected non-OEM electrical components, including a twisted white wire pair and burgundy connector, routed through the passenger-side fuse box and terminating at a footwell speaker or unknown transducer. RF scans (TinySA) showed consistent emissions at 93–106.6 MHz in the cabin, even with the engine off. Symptoms include localized EM exposure targeting genital area, neurological disorientation, and floorboard vibration. Vehicle appears modified to emit or transmit RF signals through concealed hardware. No such system is listed in OEM wiring diagrams. BMW dealership and manufacturer have been contacted to confirm authenticity. Components do not match any standard E92/E93 harness or speaker wiring. This poses a serious safety risk due to chronic RF exposure and unknown signal sources. Symptoms intensify when seated in the car, even stationary. Evidence includes RF spectrum logs, wiring photos, and physical inspection reports. Investigation is requested into vehicle tampering, electrical abuse, and shielding failure.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
