First time on Bimmerfest, can someone please help me out, i have a 2012 750LI 53k miles. the car has been towed to the dealership twice before for the the drivetrain malfunction light and the last time they told me about the customer care package repair. spoke to mechanic about the car and he told me they were having serious issues with cars with that engine, don't know what all they did but they had it for a few days. now yesterday light came on again and i got car towed back to dealership but since it is out of warranty the service advisor told me 3 fuel injectors are misfiring and i would cost 3k to repair!! shouldn't this be under warranty due to them not fixing the issue the first time. they told me work covered under factory warranty is not covered after warranty expire, only if i would have paid out of pocket for repair would it be covered. any advice would be grateful-Andy
