Upon recently driving a family member's 2005 Toyota 4runner limited v8, I heard a knocking noise coming from the front of the vehicle over bumps. Upon inspecting the vehicle, I discovered extensive rust on nearly every single part of the structural frame, suspension components and even exhaust system. Some parts are so badly rusted that they can be punctured by simply pushing your finger through them (including the rear frame cross member crash structure behind the rear bumper). These vehicles are rusting so terribly that I'm shocked NHTSA hasn't forced Toyota to recall them. Yes, they're older, but the level of rust and decay is unprecedented for nearly any modern car. Toyota already had to recall all of their other body-on-frame vehicles (tacoma, tundra, sequoia, and land cruiser) to replace the frames due to rust. Why have they neglected the 4runner when it's arguably the vehicle that will likely see use off road more than all the others? the NHTSA should force Toyota to recall these cars before someone is killed. Look at any online forum as I did last night and you'll see Toyota is actually being sued in a class action lawsuit for this very issue. Tons of people are sharing photos and stories of their own incidents. Someone is going to be killed when their car disintegrates as they drive down the road and they lose control of their steering, braking or if they're hit in a collision and the structural members of the car crumble like a cracker.
Tl- the contact owns a 2005 Toyota 4runner. The contact stated that while driving a noise of metal to metal occurs. The contact coasted over to the side of the road and noticed the whole framed has corroded; the contact stated that the front bumper frame rusted out and the rear right frame suspension mount corroded through and was detached. The contact stated that the rear left frame suspension mount heavily corroded but was ok. The vehicle was not taken to a dealer or an independent mechanic for a diagnostic testing. The manufacturer was not notified of the failure. The approximate failure mileage was 183,000. Aw.
