2006 Nissan Altima Sedan 3.5 SE 4dr Sedan (3.5L 6cyl 5A)
Will not buy again
  This has been a nightmare from the day I bought it. I had to call NIssan for assistance and they sent me a physc evaluation questionaire before they would assist. The car smells of antifreeze. The seat belts lock and will not unlock. They were replaced on one seat and the problem got worse. I am on my third set of brakes and 3rd rotor on the left front. After each brake job the car rides decent for about 5000 miles and then the vibrations start. The rotors overheat and warp. Definite design flaw. Dealer always says no problem found with all problems. I will never buy from the dealer or Nissan again. 92,000 miles of unpleasant experience. Average mileage mostly highway 23 mpg.
