20260108ENGINE
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, pol

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.

20240628SEAT BELTS
This automobile is designed with a seatbelt assembly which has an arm which reaches out to bring your your seatbelt. See pix. It is made with plastic and glue and is amazingly flimsy. I cannot believe that BMW created such a "cute" but flimsy design. It cannot withstand being used hundreds of time when the seatbelt is used. It broke (see pix). Now a rigid arm with a jagged edge comes out at eye level. Someone is going to become seriously injured!!!! BMW claims that this resulted from misuse and not faulty cheap design and wants me to pay for the repair!!!!!!! This entire assembly needs to be recalled and replaced with some thing sturdier.

The seat belt retractor keeps breaking, dealer fixed it once, broke after two days, dealer did not want to fix again, arguing for over a year, finally they fixed it supposedly, it broke again in less than a week. Dealer refuses to fix the problem saying that they will not cover it, this is a safety issue which scares me as the seat belt does not work well.
