I am guessing the re-call has not been done yet. I haven't got my letter yet. So if it hasn't been done, it can be done at a later time. The biggest weakness, well actually 2 of them, is price and ride. The price of a used 4Runner should be fairly high. The ride can be bouncy. There really isn't any big weakness. I would have it checked out, especially if it is 4 wheel drive. The inside of the chrome bumpers, if you have them, will be rusted a bit, especially on the back bumper. This happens to all of the bumpers, but look out for other rust and bent parts under the car. The 4Runners are know for thier reliability and if kept up, it should last you a long time.
