Owner Complaints for the 2021 BMW 430I

11 complaints have been filed with NHTSA for the 2021 BMW 430I. Below is a breakdown by vehicle component.

Most Recent Complaints

#11715568 | ELECTRICAL SYSTEM | | N/A miles
The contact called for the owner of the 2021 BMW 430I. The owner received notification of NHTSA Campaign Number: 25V636000 (Electrical System); however, the part to do the recall repair was not yet available. The local dealer was not contacted. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was made aware of the issue. The contact had not experienced a failure.
#11709689 | ENGINE | | N/A miles
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.

#11701950 | ELECTRICAL SYSTEM | | N/A miles
Due to the severity of the current safety recall i am reaching out for BMW to supply a correction/remedy for the starter issue. This issue is causing added anxiety and this being my only reliable transportation is troublesome. If they are unable to fix the issue I am asking that they buy the car back so people can get other vehicles that don't run the risk of spontaneously combusting.
