Owner complaint summary

While driving this new 2025 BMW X5 M60i vehicle with only 6200 miles, all of a sudden battery failure indicator came on in the middle of traffic, followed by drivetrain failure / malfunction indicator came on. BMW roadside assistance was contacted, and advised me to have vehicle stopped and pulled over immediately and towed. Situation was dangerous as the traffic was flowing at 40 mph. Vehicle Eventually totally lost power. It was towed to local BMW dealership where it was purchased from. The dealership service department was able to reproduce the issue, confirmed that it was a cracked transmission casing, resulting in fluid leak, causing electrical failure and leading to mechanical failure. BMW head office was contacted By the dealership service department and new transmission was requested. Please refer to pages 3 and 4 of the service report attached for details. This is a brand-new vehicle, bought directly from dealership 5 months ago, and had been driven with caution and care. No prior indicators were ever noticed. My safety and safety of nearby vehicles was compromised due to the fact that power was suddenly lost and engine failure unexpectedly occured at such low mileage in fastr flowing traffic. It is incomprehensible that a brand-new vehicle such as this would all of a sudden develop a serious malfunction without prior warning, and have a cracked / broken transmission casing which was found to be leaking fluids. It seems it was defective to begin with.
