You have one of the best car sold today, and you're complaining?
Like the first post said, you should have gotten a manual, the TSX is a driver's car with razor sharp handling.. if you want low noise and a numb driving experience, get yourself a Buick.
The TSX is one of the best 4 cylinder engines available in the market. The manual give you amazing control, and lets you kick the car into high gear, and the automatic gives you a comfortable smooth ride and a higher resale value.
Coming from Toronto, Ontario Canada, the TSX is loved among everyone here.
You shouldn't complain, your car is amazing and I am sure it will last you without any issues for 10 years.
Re: fit and finish, that car, which outside North America is really just another Honda Accord sedan, actually has some of the best plastics in a Japanese car. Up to Audi level (I drive an Audi). The feel of the switches is German tactile, even if there are too many in the centre stack by the radio and aircon. The doors shut like a German car.
It never fails to astonish me that Acura is selling this car as an alternative to a 3-series BMW when it's just a family car elsewhere, albeit with a good handling/comfort balance for a FWD car.
Acura TSX has one of the highest resale values of any car. It is recommended by Consumer Reports year after year. Many of the car magazines since the car came out have been very positive. Generally, they do favor the manual six speed as being the most fun to drive. Maybe your gas mileage is terrible as a result of trying to accelerate quickly.
It would seem that the dealership being very concerned about how you rate their service would be a positive.
