CarComplaints.com Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

I own a 2006 Toyota 4Runner Sport and have major rust issue with the frame of vehicle. Toyota is aware of this issue and I believe it is a safety hazard. No way should it rust like it has.
