Unfortunately my first post isn't a good one. Wife got a a180 6 speed manual 2014 model a class a few days ago. Going up gears it's perfect. Coming back down 3rd gear doesn't seem right. Sometimes if you go 4th to 3rd it feels like it's coming out of 3rd and you get that awful grind noise now it isn't all the time and if you "push" it into 3rd it seems to be ok. There's only 33k on the car has warranty etc. Anyone else had any issues? Thanks.
