Greetings, I was getting my 2011 4Runner inspected today (at the dealership) and they found a few rust holes in the frame and would not pass it. I have 227k on it and live in PA. I can see surface rust all over the bottom but I’m concerned with this becoming a recurring problem if I simply get the current visible spots fixed. If anyone has any experience here, I would really appreciate it. I have had no issues with this thing for 13 years but am concerned that this may be a killer.
