One bad bearing would allow me the driver to possibly control the car until it is safely out of traffic. Four failed wheel bearings could cause the driver to lose all control of the vehicle and or the wheels to disengage from the vehicle which has the potential for serious injury or death. A disengaged wheel could fly off and cause harm to other drivers or pedestrians, or the driver themselves could lose control and crash. Yes, the service department at the Buick dealer confirmed four wheel bearings failed on May 7th. Yes I received another inspection from an independent auto repair servicer.
