My 2008 white Sentra is also showing some issues on the paint job. I do only hand wash my car with ZipWax car wash, and have never take it to a car wash,. Bought it brand new around August 2008. The clear coat on the front fascia, hood, rear bumper, and trunk lid have faded to the point I took my car to the dealer for an inspection. They blame the clear coat fading on acid rain and said I need to take my car to a body shop and get the paint buffed at my cost to get the original shine back on the clear coat. I live in Florida where most of the vehicles get really exposed to the elements and I find the dealer's excuse is very poor. I am contacting Nissan to request technical assistance to get the paint job inspected by themselves. I have noticed at least two other people have posted the same issue on Edmunds.com forum on same year cars that were bought around the same date so I can not discard the possibility of a factory paint job issue on this situation. Waiting for a resolution from Nissan. Have anybody experienced the same issue, specially on light colored cars like white or silver? Thanks for your feedback.
