2009 Nissan Altima Sedan 2.5 S 4dr Sedan (2.5L 4cyl CVT)
Worst transmission, engine, and noise
 I don't actually own an Altima (thank God), however, a friend of mine has one and I honestly hate it more than any other midsized car sold in America.  The car uses what I consider to be the worst transmission offered on any car, anywhere. That, combined with the engine, produces mediocre power, lazy throttle acceleration, and the absolute worst engine noise conceivable. Combine that with an EXTREMELY outdated exterior/interior, unbearable rear seats, a mediocre sound system, and a lack of joy, and you are left with what is quite possibly the worst midsized car sold today. Seriously, I hate that CVT transmission. The transmission takes what little power there is and reduces it to nothing.
