I have a 2005 Toyota 4runner with frame rust that has caused everything under my 4runner to rust. Toyota knows these frames have problems with rust and corrosion and have done nothing, I am far from being the only one with this complaint or problem. It is up for inspection anytime. I have taken it to get work done at shops and been turned away because of the amount of rust on all bolts, lines, all metal under truck causing it to be a liability. I cant even get my skid plates off to fully address the issue. The metal is starting to split on the main frame by the tire, it is rotting from inside. Rust has always been there but last couple years has gotten really bad. So much rust my gas tank strap has broken but so much rust I cant get the skid plate off to fix it.

Frame corrosion
On August 7, 2018, the Office of Defects Investigation (ODI) received a defect petition from Mr. Gary Weinreich alleging premature frame corrosion failure in model year (MY) 2002 - 2006 Toyota 4Runner vehicles. The petitioner based his request upon a corrosion-related front suspension failure he experienced in his MY 2005 Toyota 4Runner, a class action lawsuit settlement involving other Toyota products, and other complaints of underbody corrosion in Toyota 4Runner vehicles that he found in the federal safety agency?s online complaint database. The petitioner submitted a complaint to the federal safety agency documenting his experience (the federal safety agency ID 11098055). On August 17, 2018, ODI opened DP18-002 to evaluate the petitioner?s request. ODI?s evaluation included information provided by the petitioner regarding his vehicle, facts related to the class action lawsuit cited by the petitioner, and consumer complaint data received by the federal safety agency regarding underbody corrosion in third and fourth-generation Toyota 4Runner vehicles.The undercarriage of the petitioner?s vehicle exhibited severe corrosion damage indicative of seawater immersion. The vehicle?s service history shows that concerns with underbody corrosion were first noted by a Toyota dealer in a multi-point vehicle inspection performed on April 28, 2011. The invoice for that inspection noted ?severe and excessive amount of rust on the undercarriage and on the drive shaft transmission.? Two years later, on October 21, 2013, another multi-point inspection by a Toyota dealer observed further progression of underbody corrosion damage, noting: ?rust on shocks/struts and other components,? ?rust on exhaust system,? ?both splash shields severely rusted,? and ?undercarriage very rusty.? On July 17, 2017, approximately 10 months prior to experiencing the suspension failure incident, an independent repair facility performing routine oil change and brake maintenance informed the Petitioner of a concern with ?excessive frame corrosion? on his vehicle. The service history, severe general corrosion damage, failure age, and environment do not support the petitioner?s allegation of premature corrosion failure.ODI?s analysis of the federal safety agency complaint data identified fifteen incidents of front lower control arm failure in fourth-generation Toyota 4Runner sport utility vehicles. Two of the failures, including the petitioner?s vehicle, involve vehicles operated in ocean front communities with continuous exposure to aerosolized marine salts and potential exposure to seawater immersion. The remaining thirteen failures all involved vehicles owned or previously registered in states with the greatest use of deicing salts to treat road surfaces in winter months (?Salt states?). On average, the front lower control arm failures occurred after 13.1 years in service in highly corrosive environments. The failure ages and environments do not support the petitioner?s allegation of premature corrosion failure. the federal safety agency is authorized to issue an order requiring notification and remedy of a defect if the Agency?s investigation shows a defect in design, construction, or performance of a motor vehicle that presents an unreasonable risk to safety. 49 U.S.C. ?? 30102(a)(9), 30118. Since the information before the Agency is not indicative of a vehicle-based defect, it is unlikely that any investigation opened because of granting this petition would result in an order concerning the notification and remedy of a safety-related defect. Therefore, upon full consideration of the information presented in the petition and the potential risks to safety, the petition is denied. The denial of this petition does not foreclose the Agency from taking further action if warranted or the p

What 2005 Toyota 4RUNNER owners say
Most recent owner complaints, unedited.
The contact owns a 2005 Toyota 4Runner. The contact stated that while driving at an undisclosed speed, the vehicle briefly hesitated and was unable to accelerate, prompting the contact to discontinue driving the vehicle. The check engine warning light was illuminated. The vehicle was taken to an independent mechanic, who diagnosed a failure with the catalytic converter. The contact was also made aware that the mechanic discovered excessive corrosion covering the entire subframe of the vehicle. The contact was advised not to drive the vehicle. The vehicle was not repaired. The manufacturer was notified of the failure but provided no assistance. The failure mileage was 205,000.
- The undercarriage and frame have had premature rusting for years. The car is otherwise in excellent condition due to my care of it over the last 20 years. 5 years ago, a service person at my local Toyota dealership said, "I'm really disappointed in Toyota, I've never seen rust like this." I have now recently been told by a local service shop that it's time to get a new car. The lines are all corroded for the power steering, etc, and he was unable to even "touch them," and said that the rust issue is no longer safe, and we shouldn't drive far from home. - We are now unable to drive the car much, as we live in the country and have far communities. With a [XXX] , we are unwilling to drive the car over 45 mph, or more than 10 miles for fear of an accident after reading about the manufacturing defect in this model of the 4-Runner. - It has not been inspected by the above stated people. - no warnings, I would not have know the vehicle had such severe premature rusting issues if it weren't for a service person telling me such. -My vehicle has under 140k miles on it, and I've taken exceptional care of it over the past 20 years. I could have sold it for 10k given its condition, and low mileage, but it is now likely worth nothing given the manufacturing defect which caused premature rusting.

When I first saw the pictures on the internet, I noticed that the front underside appeared to have rust issues. (Frontal shot) I contacted that sales person and he blew me off when I requested photos of the underbody. After several attempts, he finally sent a couple of pictures. The pictures obviously did not show the major rust issues as I have provided. The pictures were carefully fabricated not to show the major rust issues. It was apparent that the vehicle was taken off the internet while they hid the rusty underbody by applying some coating. A short time later, the dealership reposted the vehicle on their website. The vehicle was not properly advertised as having this major rust issue. I asked the salesman if his family was driving the vehicle, would he feel safe. He replied, "Absolutely". With this said, I decided to purchase the vehicle. Also, my signature is not on the "We owe". Also, the vehicle has an exhaust leak from the manifold area. It makes a loud ticking noise. This is going to cost approximately $1,500 to fix. The air conditioner is not blowing cold and either has a leak or in need of freon. This is another repair out of my pocket. This is what kind of pre-owned vehicle they sold me. This vehicle should have never been listed for sale.
Frame rot. The frame on the 4Runner is a known problem for excessive rot. My frame is shot. There is no reason a frame on a 2005 should be rotted. I was advised by my mechanic that my frame is dangerously close to snapping in half. This needs fixed by Toyota!
Under frame is rusted. The area between the doors in the passenger side is gone. only the top face of the member is present.
Frame has very severe rust and has started to come part in places. Soon vehicle will no longer be road worthy.
The contact owns a 2005 Toyota 4Runner. The contact stated that the subframe was rusted. The TPMS warning light was illuminated. The vehicle was taken to an independent mechanic, who repaired the TPMS, but the failure persisted. The vehicle was taken to the local dealer, where it was diagnosed that the frame was rusted and recommended that the vehicle no longer be driven. The mechanic referred the contact to the manufacturer. The vehicle was not repaired. The manufacturer was contacted and referred the contact to the federal safety agency Hotline. The failure mileage was approximately 200,948.
Frame of the vehicle is showing rust corrosion. The frame are the same as the tacomas that were released the same year. The tacomas were granted frame replacement by Toyota but 4Runners weren’t. Noticed a lot of other 4th generation 4Runners are having the same issues.
The contact owns a 2005 Toyota 4Runner. The contact stated while the vehicle was at the independent mechanic for servicing, and he was informed that the sub frame was severely corroded. The dealer was notified of the failure and referred the contact to the manufacturer. The manufacturer was notified of the failure and referred the contact to the federal safety agency Hotline for assistance. The vehicle was not repaired. The failure mileage was approximately 166,000.
