I purchased my 2023 BMW 430i, coupe, X-Drive brand new on 04/14/2023 from BMW, Wesley Chapel Florida. On 05/14/2025, I observed my driver's side front seat belt to be extremely frayed and in an unsafe condition (see photo 05142025) and reported it to BMW Wesley Chapel immediately. The service manager advised me this was very unusual and he has never seen this condition before, but explained BMW Warranty will likely call it "normal wear and tear." The vehicle is under factory warranty for 5 years or 50K miles and it should be noted at the time of this incident the vehicle had 34,758 miles. BMW Wesley Chapel then offered a "one time goodwill replacement" for the seat belt as they could not figure out what caused this safety issue (seat belt only replaced). On 06/08/2025, uncertain mileage, I returned to BMW Wesley Chapel as the driver's side front seat belt began fraying for the second time since replacement (see photo 06082025). Again, they could not determine the causation for the fraying, but replaced the extender arm and the damaged seat belt. On 02/08/2026, at approximately 45,000 miles, I returned to BMW Wesley Chapel as the driver's side front seat belt began fraying for the third time (see photo 02082026). The "Service Tech Expert" as I was informed, was unable to determine the cause and the seat belt was not replaced and described it as normal wear and tear. I was advised if it got worse to return. I was also advised by my service advisor that he had another customer with the same exact problem with the same exact vehicle. Research has shown, this is becoming noted safety issue by BMW drivers (see below screenshot photos). I am currently on my third seat belt in three years and concerned BMW will not replace the belt or fix the problem. I am under factory warranty for approximately 1 more year and 4K additional miles. BMW USA has been advised and will not provide information regarding seat belt life spans or related issues.

We were driving the vehicle on a vacation, and am error came on that the gear was malfunction and parking will disable vehicle. At this fine, we kept trying to clear the message to be able to view navigation, and error message kept coming back making it impossible to drive. We then parked the vehicle and had vehicle towed. Tow could not put car in neutral, and had to physically pull vehicle on to flatbed. Service advisor said water from cup holder area got into the controller.
