2008 Infiniti G

Engine not specified

13640 mi Noticed that the AWD did not work (rear wheels only) when the car got stuck on snow. Brought the car to the first dealer, who insisted that nothing was wrong with the car as the computer says "it's OK". Obviously not having AWD was not OK for me. Dealer replaced transfer case because the AWD system was not working. First dealership we brought the car to had claimed there was no problem because the computer said "it's OK"
