Electronic Motor Mounts

My 2000 Maxima just had it's electronic motor mount burn out. I was quite supprisee, because I didn't even know It had them and also didn't know that you can't start the car after they burned out. I read a Technical Service Bulletin (01-010) about it. I was wondering if anyone know more about this, or has had it happen to them. I was told it would be about $1000 to have it fixed at the dealer

Thanks
