My 2001 XTERRA has been mechanically flawless and fun, but has many areas of corrosion. A small dime sized (spider web like)area in the middle of the back hatch. A dime sized (bubble)area on the flat of the front edge of the hood. A pea sized (spot)area on the driver's side door. And all the seat anchors are rusting. Warranty covers this, I know, and I've taken the proper actions through my dealership. I'm just worried that there will be more instances, repeatedly, leading to when my coverage runs out. Any advice otherwise.
