The frame and structure have rusted from the inside out to an alarming degree. Specifically at the frame weld points in midsection and the rear attachments to axle. It is a safety hazard and it has rusted far more quickly and dramatically than any of the other components. None of my other vehicles have deteriorated in this way.

I've had this 2004 Toyota 4runner since 2004 I bought it new and have taken good care of it. The body still looks great, no rust on body just has 94000 miles on it. But the under side is awful the frame has holes rusted through at high pressure points like suspension points, cross members for transmission and engine rusted through, its to point that its dangerous to drive. I was told by Toyota service rep that the frame has a fifteen year warranty on them but together are saying they can't fix or place it and it looks like I'm not alone on this issue. Toyota should step up and back their product especially in safety issues. They were forced to replace frames on the Tacoma's. what's funny I've been told by Toyota reps also that the 4runner has the very same frame as the Tacoma's. so if that's so why can't they replace these also? I think this is really bad, you pay a lot for a vehicle and it still looks like new but have to consider parking it because you fear for your families lives. It's getting to point you can't trust it on the road. I think Toyota should be held accountable.

Frame is rusting out creating a driving hazard which could result in injury to driver and or passengers

My 2004 Toyota 4runner frame/chasis is rusted throughout. Everything that is not plastic or rubber on the chasis is rusted out. The skid plate is rusted through in several places and needs to be removed or replaced before it falls off. Toyota has recalled vehicles in the past as well as replaced chasis on all but the 2004. Toyota needs to take responsibility and recall the 2004's. the body is in good shape with no rust.

My 2004 Toyota 4runner has extreme amounts of rust on the frame to the point where there are actual holes forming. This is a major structural issue for the vehicle and incredibly unsafe. I worry that this may cause an accident or render my vehicle inoperable in the future.

Extreme frame rust on my 2004 Toyota 4runner. Has only 82,000 miles and well maintained. Body in good condition, no rust at all. Has a lot of rust in the engine compartment also, tabs, lines etc. I know there was a recall on the Tacoma for frame rust and I am aware that this vehicle is on a Tacoma frame. It is becoming unsafe to drive. I bought this vehicle new because I though the Toyota brand was a well built vehicle, but all this rust makes me think different. I have a 1999 Ford Taurus with well over 100,000 miles on it and has no where near the rust that this Toyota has, as a matter of fact there is no rust on the Ford frame. I am hoping that I can get some help from Toyota in correcting this problem with the frame on my vehicle. When I mentioned it to a Toyota service mgr. When it had much less miles on it his response was "well the vehicle is 7 years old, what do you expect" and would do nothing.

Severe chassis rust, possibly affecting vehicle and personal safety

- Elgin, IL, USA

Frame and rear axle housing rust - caused the upper control arms, which prevent rotation of the rear axel, to disconnect from the housing/frame. Also, steering has become stiff and bumpy as you turn the wheel. This may be due to front crossmember rust or rust on the steering universal joint. I live on long island and have the car bottom washed whenever it has been exposed to snow melting salts/compounds. My mechanic says the car is not safe to drive.

My 2004 4runner, with less than 80,000 miles, has significant and overwhelming under carriage rust. There is a frame rot hole. One of the trailing arm brackets on the axle has rusted to the point where the trailing arm was no longer connected. This is one of the points where the axel is connected to the vehicle and keeps the axel from rotating. There are front suspension parts completely rusted to the point my vehicle can no longer receive a successful front end alignment. These are the biggest problems, there are several other issues due to unbelievable rust.

There is lot of rust on frame, under carriage and its also in the suspension. Its also causing fluids to leak and I had to replace the muffler assembly due to rust. I purchased this car as certified used from prestige Toyota of NJ with only 5000 miles in August of 2005, I purchased this Toyota because of their stellar reputation in the auto industry but I am extremely disappointed with this car. I have less than 109,000 miles and at the way this rust is progressing, I will have to junk the car very soon. I cant risk being on the road with my family and have this rust bucket fall apart on the middle of the road. I have been waiting to see if there is a recall but haven't seen anything come through yet. Please include my car in any vehicle safety recalls, or class action suits against Toyota. Thank you

Well maintained vehicle failed nh state safety inspection based on significant frame rust. Rust points around radiator support mounts, and passenger side rail, near muffler mount, and rear suspension mount point. With damage, car is unsafe to drive. Toyota states no resolution option exists. Similar year Tacoma frames are being replaced with identical damage.

There is excessive rust/corrosion on the frame of the truck. The skid plates completely rusted off the truck in 2010. The transmission lines have corroded to the point they have to be replaced. The engine oil cooler and radiator supports have rusted through. The exhaust rusted off the truck in 2010 as well. Currently there is extensive corrosion on the frame of the truck and the suspension components. These issues appeared in 2010 and I have been fighting them ever since. Mechanically the truck runs great, never a problem, however the vehicle's frame is disintegrating due to corrosion.

- Stafford, VA, USA

Vehicle has 129,881 miles. Severe rust through of frame underside. Had plated & welded. New rust through holes appeared within 6 months of previous weld on same frame structure but in different locations posing imminent rust through failure in center of vehicle. Cannot pass safety inspection.

- Queensbury, NY, USA

Excessive rust and corrosion to the point where my skid plate came off and transmission fluid lines broke apart, leading to major leak and fix - luckily it came off in driveway and not on highway where someone could have been significantly injured. Shocks have holes in them from rust and corrosion, as do support bars and frame. Can break off pieces of the frame in my hand without effort. Concerned that frame could crack, support components could fail while driving because of corrosion. Other Toyota models have been recalled for rust, using the same components but assembled in different factories than the 4runner and land cruiser models, to my understanding. This is a safety issue that Toyota must address before anyone is seriously injured.

2004 Toyota 4runner limited, has excessive chassis rust and rotted out at some point on the sub frame, contacted the dealer and there is no recall available also called Toyota and recall is not available.I am afraid that the chassis will break and cause an accident.

- Bayonne , NJ, USA

Frame has started rusting near welds and holes. Very poor prevention of rust by Toyota. Skid plates totally rusted out and fuzed bolts. Rear diff housing is also rusty. Car will probably fall apart in a year or two.

I was going 5 mph and hit my brakes. The control arm was ripped from the frame due to rot/rust. Toyota is aware of this problem for 4runners, but has only offered assistance on the Tacoma and Tundra. The body of my vehicle has no rust anywhere, and the mileage is extremely low. I cannot even find a mechanic to fix it, because the frame is so bad. I was told, if it gets fixed, another part of the frame may fail when I'm cruising on the highway and people could get hurt or killed. No mechanic wants this liability in doing a repair.

Went in for a oil change and was offered a 28 point inspection. At dealership, ira Toyota, milford, MA 28 point inspection tells us there is holes and rust in the frame and the vehicle would not pass inspection. This 4runner has been kept in mint condition with receipts to prove. Did some research on line to learn many 4runners and Tundra's have been recalled for just this reason.
