What this page shows
Everything below is an owner-reported complaint submitted to NHTSA about the 2012 BMW 335IS, grouped by the component NHTSA recorded on the report. These are not confirmed defects, and they are not recalls. NHTSA does not verify most reports before publishing them, and a category with more reports in it is not evidence that a part is defective.
Complaints are reports submitted by owners and drivers to NHTSA. They are not verified and do not establish that a defect exists.

Percentages are of component mentions. A single complaint can name more than one component, so these do not sum to the total complaint count.
Each component in detail
What the reports in each category say, in the owners' own words
Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
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.

Body & structure
Reports naming the vehicle structure, frame, body panels, doors, hood and trim.

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.
