 This vehicle has been fairly reliable. It has had the crank position and cam position sensors both fail at different times. This is fairly easy and cheep repair if you have any knowledge, but the latest problem that Nissan knows about and refuses to fix is much more expensive and requires special tools. The floor boards on 2002- 2006 Altima's rots out leaving a gaping hole under the drivers and passengers feet. They even had a class action suit flied against them but it was denied by a judge. This car was bought new and has been taken care of no other spots on this car have any rust at all.
