I agree. Most of the frame on my truck is not boxed in, but, the part where it is DID rust. I had it patched and am not concerned about it anymore. The rest of the frame is solid. But the problem lies in the production of the steel and/or undercoating. Some say it is the design but you have to look at the specific tsb put out by Toyota. If I understand it all correctly, Toyota made good on the tsb for the second round of vehicles so that they could avoid a federally forced buyback program. In other words, because they are being proactive in trying to resolve the consumer complaints, the federal government won't force them to perform and buy back the vehicles that have bad frames. If you look at all the tsb announcements and buy backs there are very few years of toyota production that are clear of being suspect for poor quality steel. I think there are 3 or 4 years of production that are in the clear. Like I said before, I really like my old Tacoma but when I found rust on the frame and started poking around and doing research I realized how many horror stories there really are out there. I know of three people in my circle of friends who had fairly new toyota tacomas with low mileage whose trucks were deemed unsafe and totaled due to frame rust with no compensation at all from Toyota. I mean less than 100k miles.
