Owner complaintsComplaints 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.

Safety recallsA safety recall is issued when a manufacturer or NHTSA determines that a vehicle has a safety-related defect or does not comply with a federal motor vehicle safety standard. Recall repairs are free. Whether a specific vehicle is covered depends on its VIN — a recall listed for a model year does not necessarily apply to every vehicle of that year.

InvestigationsNHTSA opens an investigation to examine whether a safety defect may exist. An open investigation is not a determination that a defect exists, and many investigations close without a recall. Investigations can, however, lead to one.

The component that malfunctioned is the engine starter relay, which is subject to an open BMW/NHTSA safety recall (issued September 2025) due to potential corrosion causing overheating, short circuits, and vehicle fire risk. The recall specifically advises parking the vehicle outside and away from structures until repaired. The vehicle is available for inspection upon request.My safety and the safety of my family were put at risk because the dealership (Capitol Nissan in San Jose) failed to disclose this critical fire-risk recall before or during the sale on January 4, 2026, despite it being noted on the provided Carfax report (without any explanation of its severity). I only learned of the fire hazard and "park outside" warning when an authorized BMW dealer informed me during an inspection on January 5, 2026.The recall issue has been confirmed by an authorized BMW dealer on January 5, 2026.The vehicle has been inspected by an authorized BMW dealer, but not yet by the manufacturer, police, or insurance representatives.There were no warning lamps, messages, or other symptoms that I noticed prior to purchase, as the problem is related to a latent defect covered by the recall. The issue was UNKNOWN to me until the BMW dealer informed me after the purchase.In addition, the dealership engaged in other fraudulent practices, including structuring my full cash payment as self-financed (with themselves as both seller and creditor) and adding unauthorized charges, but the primary safety concern prompting this report is the undisclosed fire-risk recall.

ELECTRICAL SYSTEM; VISIBILITY:DEFROSTER/DEFOGGER/HVAC SYSTEM

An interference noise (groaning noise) can be heard from within the heating and air-conditioning unit in thecenter of the instrument panel. The groaning noise always occurs when either a ventilation flap, air stratification flap or the recirculated airflap moves to a different position. Due to the complex design of the heating and air-conditioning unit, the kinematics causing it (top or bottom,left or right) may not be able to be precisely located. Depending on the vehicle model, the number of servomotors (and the associated kinematics unit) varies.Various models use either 2 or 3 servomotors.

Manufacturers file copies of the bulletins they send to dealers with NHTSA. These often describe diagnostic or repair procedures for a known condition. They are not recalls: repairs described in a bulletin are usually only free if the vehicle is still under warranty or the manufacturer has extended coverage.
