My car is a 2006 Toyota 4Runner. This past summer I had a tire leaking and took it to the garage for repair. The mechanic stated that the frame is rusting out in the front right, tire rod area, and saw a pinhole. Last week I took the vehicle to get a transmission oil change. That mechanic saw that there's more rust that is spreading throughout the entire frame, worse than the area found from just a few months ago. I learned online that Toyota had purposely used cheap steel for the frame and had replaced the same frame used on other trucks such as the Tacoma and Highlander but is refusing to replace the 4Runner. These rusted out frames are affecting many 4Runners. I have a 1964 Cadillac and that frame is in better condition than the 4Runner. I'm forced to pay $15,000 to replace the frame or salvage my car. It shouldn't have come to this, especially when the same frame that was replace on other trucks isn't being replaced for mine.

I have a 2006 Toyota 4Runner. I also have a 2005 GMC Sierra, but this 4Runner's frame is absolutely toast, while the GMC is completely fine. Toyota issued recalls on the tacoma, tundra, and the sequoia, so why not the 4Runner? My car started swaying and violently shaking on the highway. I pulled over and looked underneath, only to see the rear section of the frame had completely disconnected. This could have caused a major accident or even death if I did not catch it soon enough. This is a MASSIVE safety issue, and if people do not know what to look for with these, Toyota will be seeing a lot of wrongful death lawsuits.

Vehicle failed inspection due to rust on the frame. Bought vehicle because it is supposedly ruggedly built and for the frame to rust out when the vehicle has 103k miles and not driven off-road for more than a few times since we owned it is ridiculous. Dealer quoted $11k for the frame alone, not including labor. The fact this vehicle shares the platform with the Tacoma which was recalled for frame does not make sense. Vehicle was inspected last year (Virginia requires annual safety inspections), so given the amount of rust discovered makes me doubt whether or not the Toyota dealership did a thorough job inspecting the vehicle last year. We don't drive the vehicle that much so it doesn't make sense that it would rust som significantly.

Since an inspection Oct 2021 the rust/corrosive on the frame has become. Dangerously close to rotting thru the entire frame! It-??s not driven in the winter months when snow or ice melt (salt) is on the roads to prevent situations like this. With only 75,000 miles always garage kept and maintained like it-??s brand new this vehicle might be able to be saved for a model in a shop class to practice welding. Something needs to be done because this ifvvjj

The Frame and Suspension Components of the vehicle have corroded or rusted badly and prematurely even though the rest of the vehicle is in excellent condition. This is a known and common occurrence with the 4th Generation Toyota 4Runner Vehicles such as this 2006 model. - Currently the upper Rear Differential Stabilizer Arm has completely rusted off causing handling problems with the vehicle. Many areas of the frame are rusted through making it difficult to jack up or raise the vehicle on a hoist. - Problem has been observed and reported by Dealer(s) and Independent Shops I have visited. - This has NOT as yet been inspected by manufacturer representatives other than dealers. - This first appeared in late 2012 when I purchased the vehicle used with approx. 75,000 miles. - In May 2015 I struck a deer with the vehicle travelling on a US Trunk Hwy and the rust problem was reported as being severe by the body shop who repaired the front end damage. Note: The corrosion, in my opinion, did NOT cause the accident with the deer.

My 2006 Toyota 4 runner, I've found a large amount of rust through out the frame of the vehicle. I feel the vehicle is not safe to drive. Toyota has frame replacement recalls to the Tundra, and sequias but not the 4runner. I feel this is an issue that Toyota is aware of. I also feel that something should be done for manufacturing a vehicle with defective chassis.

When I went to have a tail pipe replaced, it was discovered that the frame of my car was badly rusted. Upon bringing to a mechanic, an auto body shop and a Toyota dealer, they all said the car is not safe to drive. The rest of the body is in mint condition as is the interior and mechanics. I called Toyota Corporation asking for assistance, provided them with the vin and was told they would do nothing and suggested I "junk' the car. Toyota replaced the same frames on their Tacoma models under a recall and it turns out there is no recall for this model. The same frames are used on the 4Runner as well as the Tacoma. Saftcap.com in Cranston RI holds a United States patent for replacing parts of these frames and the owner feels there should have been a recall on the 4Runners just like the Tacomas.

My Toyota 4 runner entire frame and connecting components is completely rusted out and crumbling. The car isn't safe to drive at all. Toyota is aware of this as its common and no recall is in place. When driving, one tire is completely barely hanging on as the frame is failing all over. The car wobbles and swerves and feels as if it will come apart at any time. This frame was never treated properly when installed. If you went over 50 the car could fall apart and would be extremely dangerous.

Just bought a 2006 4runner and did not think to check underneath for anything. I noticed on the passenger side of the frame huge rust spots, it's rusting from inside the frame out to the surface. It's bad. I googled what I should do to fix it because now I'm out 7K for what I thought was a reliable SUV. They sell patch kits online requiring me to purchase the kits and have them welded to the frame by a professional after they clean the rust completely. That's expensive. Toyota should definitely take this seriously and not fight this claim. No truck that year should rust this bad. In fact I've bought a 77 Chevy C10 that was a farm truck most it's life and it did not have any frame rust what so ever. There's multiple claims on facebook and other 4runner specific groups online that have this same issue. A recall needs to happen. What if I didn't notice and I let my wife and kids ride in the SUV and the frame snaps in half down the highway? you recalled other models do to frame rust, but not the same year 4runner. Please help us 4runner owners fix this because all in all it's a great SUV Toyota makes some of the best product out there, we just want to keep them on the road.

I have a 2006 4runner with no rust on the body but the frame is full of rust. All body mounts have rusted away from the frame causing a wable when hitting bumps. I am so worried that the car is going to break in half at any time. It causes unusual sounds, creaking, squeaking, unusual noises, bad alignment, uneven wear in the tires, suspension, and shocks.... frame is visibly bent and severely damaged... the worst thing is that I called Toyota for service and they won't fix my frame... my mechanic said that is too far gone to fix.. I'm not able to drive it because it broke off on me..
