2013~2016 Electric driver's seat not going up and down.

The electric driver's seat on my 2016 Grand Touring has stopped going up and down. The lumbar support works and the back rests moves correctly. My local garage (who I use for maintenance and is a trustworthy guy) mentioned that the "track" needs replace and with parts and labor the cost would be $650 which was a shock. I have an appointment next week at my local Mazda dealer for a comparison. Has anyone else experienced this issue?
Thanks.
