Rusty frame

Frame rusting excessivly

The frame on my 2003 toyota 4runner has severe rust damage. i have always taken great care of this truck. regular washing, cleaning, maintenance etc... i have tried to grind off the rust, use rust inhibiting products, and undercoating without any luck. the truck is in excellent condition, but the frame is rotting away right before my eyes. i'm afraid this $37000 truck will not make it to 75000 miles. i know toyota has had recalls on the tacoma and tundra truck frames, but did not include the 4runners for some reason. the 4runner truck frames are total junk and should also be recalled. thank you for your help in this matter.

Structure complaint. frame , frame mounting points, and suspension mounting points. heavy rust. upon maintenance diagnostics for evap system the mechanics indicated significant serious corrosion problems with the forward and rearward sections of the frame. significant and dangerous deterioration to mounting points for track bars, brake line brackets, and other suspension components. structurally the frame is questionable in places and likely hazardous to continue driving, recommended that vehicle be retired as is.

Extreme frame rust. car is low mileage, well-kept, and outwardly in excellent condition. recently suffered near-total brake failure. towed it to shop for repair. shop refused to repair brakes. they said frame was severely rusted. the rust had eaten away the point where the brake lines attached to the frame, and brake fuid was leaking from that juncture. they said if they removed the brake lines to replace them, they wouldn't be able to reattach them because there wasn't enough good frame metal to work with. they said the frame rust was so severe that they feared it could break clean through, or steering or suspension parts could break loose. they did not want to take responsibility for putting what they believed to be an unsafe vehicle back on the road. they only reason i discovered this was that the rust caused my brakes to nearly fail. toyota has had recalls and lawsuits on identical issues involving tacomas and other truck-framed vehicles. the 4-runner is a truck-framed vehicle and should be recalled. i have photos that the repair shop sent me, but i can't send them ffrom this computer.

Excessive frame rust. multiple reports of this.

Had this vehicle for 4 months. low owner count, and 160k miles with good maintenance history. noticed a slight sway at times on the road, suspected tires and/or alignment. after replacing and servicing it, it was discovered the frame is rotted out extremely bad from front to back. the passenger side frame rail is completely open on the bottom from corrosion, causing stability issues and now the vehicle is unsafe to drive.

The frame of my vehicle is extremely rusted for it's age. every component attached to the frame is overly rusted as well. it is spreading like a virus throughout the under body. i am becoming increasingly concerned about hauling, towing, or even driving my vehicle due to this rust. with only 172,000 miles, this should not be occurring. i have been keeping it in a garage for the past 5 years but as the 2nd owner it's probably too little, too late. toyota should recall these vehicles as they did some other models.

Structural rust to frame. cracks and holes at welds and attachment points of suspension and steering. frame is disintegrating under the truck, complete structural failure is imminent.

I took my 4runner to the dealership that is was purchased and was informed that it needs a new frame due to excessive rust/rot. i am being told that it is beyond repair and is a safety issue at this point.

Takata recall. so i'm not understanding a problem with my toyota 4runner. as of yesterday there was a great amount of smoke coming from the area of the oil stick from my assumption the oil was getting on the cadillac converter. or something that would hit something hot on the engine to cause it to smoke i'm trying to find out if there is a recall for that.

Frame is rusting through where "front clip" joins side rails. found during normal vehicle service. vehicle deemed "safe" to use at present, but the frame will fail in the future. vehicle was purchased new, one owner, garaged, approximately 125,000 miles, all street miles, never off-roaded.

Vehicle was maintained at a toyota dealership for over a decade before being informed that vehicle is unsafe to drive due to holes forming throughout the entire frame assembly from corrosion. further research showes the frame of this vehicle resembles that of the toyota tacoma and tundra models which where recalled due to early and unsafe corrosion leading to components to detach from frame while vehicle is in motion which can lead to serious life hazard. frame and vehicle were also manufactured in ohio dana company which is the supplier of the recalled frames used in the toyota tundras and tacoma's.

The frame is rusted out and the rear suspension mounting brackets are starting to look like potato chips. also noticed steering components are severally rusted.
