whining sound during deceleration

It's best to bring it to the dealer for warranty work. You do not want to attempt a repair here since its going to be covered. I suggest calling a tow truck if you don't feel comfortable driving it. Alex

It could be as simple as a plastic bag stuck in the drivetrain somewhere but a visual inspection under the vehicle is required to determine that for sure. Alex

Mine was doing this during accelerating & deceleration, took it in & it's something with the transmission. It's dangerous. Wouldn't let me drive it home. Already had it in the shop for over a week. Just hoping they get it fixed!!!
