I have a Nissan Maxima 2000 that has had the electric motor mount(s) go bad. First time I've ever heard a bad motor mount. With the engine off, the little motor or whatever, freewheels and makes a whining noise. You have to disconnect the battery to stop the motor. What in the heck are these things for? What do they look like? carloponti;g Wanna kill these ads? We can help!
