Purchased Nissan Altima 2006 in sept. 05, from day 1 I had problems with it starting. After service had the car for 2 months I invoked the lemon law and received another Nissan Altima 2006 with the same problem. The dealer doesn't know what to do they said that these are the only 2 new Altima 2006 they've had a problem with. Then I found out these are the only 2 with factory navigation system.
