 Purchased my first new vehicle, Nissan Frontier SV 4x4 Crew Cab.  So far I have had 3 problems, Nissan has only covered one...
 1. No hole drilled for air conditioner drain.  Water leaked all over the interior and blew out of every vent.  Nissan "fixed" this.
 2. The "paint" on the rear wheel wells is literally falling off after 5,000 miles.  After several frustrating attempts Nissan refuses to fix this.  Edmunds does not allow pictures but if you do some searching you should find them. 
 3. The rear sonar now no longer works @ 8,000 miles.  
 Nissan has basically told me "No" several times to the paint, claiming its environmental.  I live on a normal street, happened at 5000 miles.
