The guibo (flex disc) in the powertrain has multiple visible cracks, posing a safety risk due to its potential to disrupt power transmission to the wheels. This malfunction could impact vehicle control, particularly at higher speeds, thus putting passengers and other road users at risk. A certified BMW service center has confirmed the problem, with BMW technicians recommending a replacement; however, both the dealer and BMW have declined to cover it under warranty. Although there were no warning lamps prior to the failure, slight vibrations or noises may have indicated an issue with the guibo. The attached image is the recommendation from the BMW service center however I declined to it repaired out of pocket.
