CarComplaints.com Notes: Although it has a stellar record in terms of vehicle problems, initially the 4th generation (2003 - 2009) 4Runner didn't earn our top "Seal of Awesome" rating because it received poor crash test ratings for rear impacts. However it's proven to have one of the lowest driver death rates out of all vehicles (not just SUVs), so we've bumped it back up to our top award.

Entire frame of the vehicle is rotten with rust and holes. This vehicle has been inspected by McDaniel Toyota, Marion, OH 43302 and the damage was confirmed. I have been and must continue to drive this vehicle even though the dealership did not recommend it. No evidence of the extent of the rust and damage was not noticed until October 2023 when a strap on the gas tank came loose. Upon further inspection, he noticed the holes and rust all over the frame. Reported to Toyota because other 2004 Models were recalled for this issue. They were of no assistance.

Frame of this vehicle completely rusted through. Holes on passenger side right where the front door ends. Hole is approx 12" long. Frame also has a hole in the left front core support. Advised that the vehicle is no longer safe to drive by my Toyota Dealer and personal mechanic.. There were no indications of this until a few weeks ago when the gas tank strap had come off and the gas tank was leaning. When inspected, it was found the frame was in disrepair.

Purchased 4 runner from a Toyota dealer in 2018 with 130k miles. During routine maintenance in 2021 with 160k. The frame was found to have several holes and wide spread corrosion. It is absurd that Toyotas was let off the hook for frame replacements. I bought this truck from the dealer and it had structural frame issues that were not disclosed at the time of sale. Frames don-??t just fall apart apart in 4 years from normal driving. Clearly Toyota is ignoring the manufacturing deficits in there frames and still re-selling these as road worthy cars. It-??s absurd that Toyota was not required to replace these and not recall has been issued. People should not be able to buy/sell one off these vehicles they are not safe due to the frames rusting from the inside-out. They need to be recalled and removed from service.

The frame is damaged from excessive corrosion. The rear cross member that supports the trailer hitch and rear bumper is almost non-existent, which could result in the loss of the trailer being towed, and it will reduce the truck's rear impact resistance. The front right lower control arm has a 2'" x 3/8" lateral hole from corrosion, which could result in a catastrophic failure of the right front suspension system. The longitudinal frame members are compromised by corrosion which has penetrated through the steel in various locations. The front cross-frame member that supports the radiator is severely corroded. The frame to body mounts are showing signs of excessive corrosion which could result in the separation of the the body from the frame in an accident.

The contact owns a 2004 Toyota 4Runner. The contact stated that he noticed that the tow hitch had separated from the frame and was laying on the ground. The contact stated upon inspecting the subframe of the vehicle, he noticed that the subframe to which the radiator mount was attached was severely corroded. The contact stated that upon changing the oil in the vehicle he noticed that the front passenger-€™s side subframe had a significant size hole. The dealer was not notified of the failure. The vehicle was not diagnosed or repaired. The manufacturer was notified of the failure and provided case numbers to the contact. The failure mileage was approximately 224,000. The contact stated that their vehicle is not a part of the recall that affects other Toyota models although other 4Runners have experienced similar issues. It was recommended to the contact to sell or trade-in their vehicle. No repairs were made.

We took our 2004 4Runner for annual vehicle inspection and the service provider told us the vehicle would not pass safety inspection due to the excessive rusting on the steel frame and the suspension of the vehicle. Welding and patchwork will not fix this issue. My husband depends on this vehicle to work. The attached pictures give a small window into the extent of the damage. There is no current recall for this vehicle and year, but similar Toyota trucks from the same time frame have been recalled for the same exact issue. The entire frame needs to be replaced or worst case scenario, the vehicle is no longer usable. Toyota needs to remedy this issue for their loyal customers immediately.

Complete frame rust-out. Suspension at rear axle disintegrated. Vehicle undriveable. My son had just taken the vehicle (moving his belongings) from Minnesota to the East Coast and back. No problems or issues. After returning, while driving the vehicle I had a hard braking event which is when I noticed something was drastically wrong. This frame failure really snuck up on us. We were lucky, no accident or incidents occurred.

I bought my 2004 Toyota 4runner Sport edition as a new car, and have been the sole owner of the vehicle. I have taken good care of it the entire time. Regular car washes, service maintenance and necessary repairs over time. I recently had my 4runner in for repairs and spent a considerable amount of money, over $6,000 in anticipation of driving it for many more years. Following the repairs I was told by the mechanic that the frame was EXTREMELY rusted and that the entire frame would need to be replaced. There are large holes rusted through in many areas of the frame and a tremendous amount of rust over the entire frame. Rusted Pieces of the frame have fallen off. I fear for the safety of my family and me if I were to drive the vehicle at all. I have barely driven it since learning of the dangerous condition of the frame. I've limited any driving at all to my immediate area, and have driven very carefully and slowly, as I am extremely concerned that there might be a catastrophic failure of the frame while driving and I may be injured or killed, or worse....the vehicle might cause harm or death to another person. I am now basically without a vehicle and have been forced to rely on my daughter's car, leaving the family with only one vehicle. This is a major failure of the vehicle. I can provide photos and video at your request. Toyota must be held accountable for the failure of this frame. The vehicle is now useless. I expect Toyota to rectify this situation immediately. Please contact me as soon as possible. Thank you. [XXX] INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).

My Car was inspected by a Virginia Inspection Station and was cited for significant rust holes in the frame which have to be repaired. The frame should not have such significant rust that it needs to be fixed or it will be a hazard on the road. Based on other litigation around Toyota fames from this period of time is seems that this is a systemic issue and should be made to provide a recall based on the safety risk that is present with a frame failure as noted in previous class-action lawsuits. The Brian Warner et al. v. Toyota Motor Sales, U.S.A., Inc., Class Action Settlement (UNITED STATES DISTRICT COURT FOR THE CENTRAL DISTRICT OF CALIFORNIA Case No. 2:15-cv-02171-FMO-FFM) is a perfect example of the risk to the public if this is not corrected.

The entire frame is rusted. It's been welded back together on 2 different occasions. The last time it happened I was pulling out of driveway and the vehicle cannot be steered at all. I live in east TN and should not have a rusted frame. This is not an isolated problem. This is a problem with the 4runners and should be recalled. There are literally 1,000's of 4runners with Rusty frames. I don't understand why this isn't being recalled. You can reach me at [XXX] or [XXX].

My 4 runner only has 147,000 miles and is a great running vehicle but my frame is rotted badly. I have large holes throughout, the front crossmember under radiator with tow hooks has completely rusted off, and now I found where my rear lower drag link bolts to frame is about to come off. I have had to repair rusty brake lines multiple times. My rear axle carrier just sheds large flakes of rust. I love this truck but now it is almost too dangerous to drive and with all the inflation lately I cannot afford another vehicle.

2004 Toyota 4Runner, original owner with roughly 210K miles. We took the vehicle to the mechanic concerning a sway bar issue. He informed us that the frame of the vehicle was nearly rusted into and that it's serious safety issue to continue to drive it. It is my understanding the Toyota recalled several other models with this same issue but did not include the 4Runner in this recall.

My steering became very loose with a lot of movement in the steering wheel. The universal joint in the steering column shaft was bad. Upon further investigation, both lower control arms on the front wheels were rusted through, (from the inside out), with one of them bent because of the lack of metal support that rusted away, which caused my wheels to be misaligned and hard to control. Upon additional inspection, the frame has rusted out in multiple places which could allow it to break in half. (pictures of one portion of the frame are attached.) I have had the steering column and lower control arms replaced but multiple body and frame shops state the frame is rusted too much to repair. I know Toyota recalled several models for frame rust issues but have not included the 4Runner, which I cannot understand. This rust has been noticed for several years on my vehicle with attempts to keep it clean and rust free. However, the rusting process is occurring from the inside of the frame toward the outside, so you can't tell how bad it really is until you see the holes protruding through the frame. This model should be included in a class action suit requiring Toyota to compensate the owners for this defect and removing these models from service to avoid potential accidents and casualties caused by inferior iron products that were used in their manufacture.
