Vehicle suddenly became very unstable and loose in the rear end while driving down highway at 50 mph. Rear end started swaying back and forth pushing vehicle into center of 2 lane highway. Once vehicle was under control and off the road frame showed significant rust. Lower suspension arm mount on frame had rusted and broke. Roughly 24 inch section of this frame area had rusted out. Leaving no attachment of the suspension arm to the frame mount. Upon inspection many areas of frame are showing signifficant rust damage. Vehicle us now unsafe to drive. I have owned this vehicle for 11-12 years. Bought it with 12,000 mile and have taken great care of it. Engine purrrrrs like a kitten. Runs as well now as when I bought it. Toyota will not warranty a bad design/manufacturing process. Called Toyota dealership whom I purchased it from and they said they have been seeing many of these coming in and Toyota will not warranty the bad frames.

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.

On October 11th 2014, I was driving my 2001 4runner, on my way to work. Had just turned off a road with a speed limit of 55. As I hit 35mph, my car comes to a jolting stop with a loud bang and drag on the tires. The car still ran, but the car wouldn't move. I had to finish walking to my job, as I was cellphone-less at the time. I had to pay to have my car towed home, missing an entire day's work, which was a loss of 120$. The guy who towed me told me it was definitely something to do with my rear end. So I had a family friend who is a retired mechanic look it over to see if he could spot what the problem was. First thing noticed was my emergency break was on and frozen. They remove it, clean it, put it back on. I start the car, go to move it and theres a continuous loud bang and the car again comes to the stop. The emergency break froze again. They once again take it off, and so far it hasn't refroze. However, my car is still making the loud banging noise coming from the rear end, which they have concluded is coming from the rear differential housing unit. Which they found a decent sized hole in, which it appears someone tried to cover with a yellow glue type substance. I just bought the car, and am now carless. As I have 2 small children, and cannot afford to fix a problem that can cost up to $3,000 to fix. Luckily I was only going 35 mph when it broke, and there was no one following behind me, or I would have been re ended, and had more to fix that I already do. This is a huge problem with the model car, and Toyota really needs to issue a recall on the differential unit!!! it's fairly dangerous. I loved this car before this incident. But now it's useless til I can afford this fix.
The frame on my 1996 4runner is rusted beyond repair. A place with significant rust had bend and would break off at any moment. The vehicle is unsafe to drive and completely useless at this point.

My mechanic told me that my perch springs/shock mounts had rotted off. Brought the vehicle to a welder and told me that the frame was so rotted out that I should contact Toyota to see if there is anything they could do. Said he had a 2000 tundra with the same issue that was recalled and replaced. Why hasn't the 4runner been recalled yet?.
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 longer due to its handling and safety.
I own a 2005 Toyota 4runner. The frame is rusting so severely that it may not pass inspection next year at this time. I live in PA. I have heard that Toyota has acknowledged that they have had frame issues with the tacoma (same chasis), the early tundras (I own a recalled 2000 with same issue), sequoias (same chasis as tundra. . . . . . Please tell me that the will recall my 4runner. I love the vehicle but the rust on the frame will kill it.

The 4runner has developed surface rust on the frame underneath the car. The rust is also apparent on suspension components and brakes.
1997 Toyota 4 runner frame rot and rust: I noticed rust debris in my driveway. I inspected under the vehicle and found that the inside of driver-side frame was completely rotted with extensive rust along entire length of adjacent fuel tank. Holes large enough to put four fingers in and crumble. It is clear that the rot has almost gone entirely through the frame as there are several small holes on outside of frame as well. The rust has also seriously compromised the weld seam on the suspension component attached to the frame. Rust and rot of this severity on this vehicle is isolated only to this area of the frame. The rest of vehicle frame shows typical surface rust as expected with age of vehicle.

I own a 2000 Toyota 4runner. Went to the dealership to inspect a leak from the rear differential. Found out that not only was the rear differential so rusted that the fluid was now leaking from the porous rusted housing. But the frame was rusted and cracked so bad that that dealership said it was unsafe to drive. My now otherwise immaculate condition 4runner is now useless and rendered inoperable. This is a ramp if problem with tacoma/tundra for the same issue and same model years. How is this not a recall.
I was going over a rail rd crossing, and there was a loud bang and knocking after. Brought it to a shop, and they said that my driver side upper, rear shock went through my shock mount.
While driving on a family vacation, the 4 runner had a near catastrophic frame failure. The speed of the vehicle at the time of the failure was approximately 30 mph. This failure caused total loss of vehicle control and the inability to safely operate the vehicle. The vehicle was rendered unsafe for operation and it had to be towed. An independent inspection revealed multiple failure points along the frame rail related to corrosion.
Rust perforation in right side rear frame rail across from fuel tank inboard side. I understand Toyota has already recalled the tacoma (same year) for the same issues however has not recalled the 4runner. Car will not pass inspection nor can dealer repair.

I heard a noise toward the rear of the vehicle, so I took it to the garage to have it checked. They informed me that the left rear frame was completely rusted into and the frame on the right side was almost as bad. I was told to take it home and park it before a bad accident happened.
The vehicle frame is deteriorating from rust on the passenger side of the vehicle. This severe rust is prevalent at suspension attachment points; significantly where the right-side rear "track bar" is attached. If this were to fail, the rear axle of the vehicle would become disconnnected from the vehicle undoubtedly causing a crash. Found out tonight the frame rail forward of the track bar has also deteriorated on the bottomside and is exhibiting numerous holes. This condition makes the vehicle unservicable from a safety aspect. It cannot be safety inspected in nys any longer. This vehicle was puchased new in ithaca, n. Y. The framework deterioration is indicative of other Toyota vehicles with frames rusting and causing major structural integrity issues. Toyota has done due diligence in supporting their customers on their tacoma and tundra vehicles. They performed frame replacements and a buyback program on these. I believe they ought to do the same for the 4runners seeing they are a virtual duplicate of the tacoma trucks' frame. The fact that the tundra and tacoma frames were produced in USA and the 4runner's frames were produced in japan does not have a bearing on this rust problem. . It does show an engineering deficiency on tundra, tacoma and 4runner's frame design. This issue is causing my family an undue financial burden. I most emphatically believe Toyota should address this issue. There should be a recall !!.
My wife was at a red light waiting for the light to change when she was hit on the driver side front fender and tire area . No air bag deployed there is over 8. 000 dollars in damages the other driver was moving 35+ mph at impact so now along with the whiplash and shoulder bruises and seat belts cuts there mental damage she feel the vehicle is not safe and is afraid to drive it when repaired in closing I feel at the speed of travel on impact the air bag should have deployed.

I am writing to report a defect in the frame of my 2000 Toyota 4runner. I just purchased this vehicle used for my 16 year old daughter to drive. Inspection by a certified mechanic revealed that the frame exhibits extensive rusting. The frame has rusted through on the passenger side between the front and rear wheels. It has holes and has separated along the bottom weld. The mechanic warned that catastrophic failure is likely to occur.
No incident to report, but a complaint about the approach being taken by Toyota to remedy the rear suspension problem described in their safety recall #csj. Their plan is to adjust / tighten the rear lower suspension arm , then seal it with epoxy, thus making it no longer adjustable. This would preventy any future rear wheel adjustments / alignments, thus creating a new safety hazard. All over the country , the roads are in bad shape ; I have my vehicles re-aligned at least once a year . I am not interested in having Toyota " fix" my car so that I can't get it re-aligned. I think it is a pretty lame and cheap way to address the issue. Thank you for looking into this.
Safety issue do to frame rot. . Common issue with 3rd gen Toyota runners. Bought the truck new, and now my investment is at risk because Toyota makes vehicles with poor steal and the us dot will not step up and force them to correct the issue.
The contact owns a 2006 Toyota 4runner. The contact stated that there was an extensive leak of an unknown fluid under the front of the vehicle. The vehicle was taken to the dealer. The technician diagnosed that the hydraulic system needed to be replaced. Also, the vehicle was taken to an independent mechanic for a second opinion who diagnosed that the suspension system needed to be replaced. The manufacturer was made aware of the failure. The approximate failure mileage was 109,000.

When driving at 70 mph, the vehicle vibrates on the highway. I have taken the vehicle constantly to the dealership for over two years complaining about this problem and they always told me that nothing was wrong. Today (5/10/14), the mechanic at the dealership put the truck on a rack and ran the car at 45 mph and there was visible vibration coming from the drive shaft and a loud noise that I could never hear from within the vehicle. All this time, I have been driving a vehicle that I was unaware could have snapped apart. The sound cannot be heard in the cabin, so I could not even report that as a problem until today. I purchased three sets of new tires, had shocks and struts replaced, and brake pads to no avail. Finally, after searching the web yesterday, I realized that this is a common problem with other vehicles of the same make and model. I'm not sure if this problem has caused injury to others, but there should be a recall. This could cause a potentially fatal accident if that shaft breaks. I read that for similar models (Toyota and Lexus), the manufacturer replaced the parts under warranty, but nothing for the 4runner. The dealership is charging over $700 for this repair.
This vehicle has accumulated a scary amount of rust on the underbody. I took it to a local Toyota dealership and they told me it probably wasn't safe to have my kids riding in this vehicle becuase of the amount of rust on the suspension.

While having an oil change done my mechanic noticed sever fram rust, some spots go right through fram. I know Toyota recalled many vechiles for this so I call Toyota and they said they can do nothing for me, they didn't even want to look at it. They said if I wanted it looked at I would have to pay! sounds like they know they have more problems but they are not going to do anything about it.
Rear frame is rusted badly where the rear suspension connects.
