I've got the same issue in my 2009. Seems to only occur when it's very hot in the car, for instance after sitting in the hot sun all day. When leaving for work in the morning when it's cooler, the controls work fine.
Maaco?? I wouldn't take my demolition derby car to get painted at Maaco. They may be cheap, but you get what you pay for. You have a nice car. Pay a little extra to have it done right.
