In September 2012 I noticed paint blistering on the tailgate of my 4runner. I now (8/13) have rust through originating from the inside middle of the tail gate. I took the truck to my local body shop and was told that this was a common problem with the 06 4runner. It was caused by a sound deafening material on the inside of the gate. "the material gets wet and holds the moisture causing body rot". this shop has repaired other 4runners with this problem. I also own a 1994 Isuzu trooper with no body rust that sits next to it in my driveway. I was told by the Toyota rep (oakdale Toyota in NY) that it was out of warranty and they could not help me. I also have extensive rust on the undercarriage. The truck has never been off road before.
