I have an auto mazda 3 skyactiv late model 2012. If I go into manual mode or not, when it or I shifts from 2nd to 3rd, lets say for example, the rpms are at 2500 right after the shift, they then suddenly drop about 200, then the car continues to accelerate normally. Also it doesn't seem as fast as when it had 1000 miles on it. It only has 6900 now. Any ideas or anyone else notice that with their own car?

 

That car is till under warranty isn't it? I would talk to the mazda dealer.

Always with warrenty take it to the dealer. I've seen people post that they have no other vehicle if they leave it at the dealer, well tell them to get you a loaner.
