general problems of the 2012 Audi S4

While driving in traffic, my car dropped into lower gears and stopped moving, and two error codes popped up "gearbox malfunction" and "tpms malfunction". Looking this up online and discussing with my mechanic, this is something happening in a lot of the cars that are this make & model and have the same transmission.

I have a complaint Audi S4 and other Audi cars have the same issue as I'm having you can be driving on the main road or on the highway and all of a sudden the car loses power and excelleration . I found that as a problem to the safety of me and the other people that have the same car model.
