The frame on my 4runner will not pass inspection due to rust, which i need to repair. The vehicle does not have much miles on it and should not rust like it did from the inside. The rust is from the inside, which makes it very dangerous to have on the road especially in states where an inspection is not required. It could easily go unnoticed until it is too late, and somebody could get hurt or killed when the frame…

On routine check and inspection, toyota arlington and toyota schaumburg called my attention regarding a premature rusting on the underbody frame and resulted in a linear hole by the rear left and right portions of the vehicle. This according to the service advisors of both toyota dealerships may make the vehicle unsafe to operate and may result to uncontrolled stability during driving. *tr

Vehicle frame is rusting to the point of perforation. I discovered today two holes, one on each the driver and passenger side, inner frame rails just behind the rear crossmember. My concern is it may be rotting from the inside out. Is the manufacturer going to issue a recall on these frames as they have done on tacomas and tundras? This car is in excellent condition otherwise and i had planned to drive it for much…

Vehicle has a frame that is rusted on passenger side and was told by a mechanic on 3/20/15 that it should be in a recall asap. Differential cover is a rusted bullet and is leaking. There is no changing it as cover is a solid weld no bolts to take off to change cover. Brilliant idea by toyota. *tr

My 2001 4runner vehicle will not pass inspection due to corrosion, actual holes and soft spot, on the rear part of the frame in the muffler area. Concerned with failure when towing 300 lbs trailer.

Severely rusty frame. My 4runner only has a little over 114k miles on it. It shouldn't have anywhere near the amount of rust on the frame. It's everywhere and flakes off to the touch. *tr
