Problems with 2006 Toyota 4Runner STRUCTURE

After only a couple of years started rusting pretty badly on frame, crossmembers and front and rear differentials. also stabilizers skid plates and basically anything under the truck. thought it was only surface rust until parts were cracking and stabilizers fell off truck. rear end was ready to drop off truck! truck only has 81,000 miles and looks brand new. wanted to keep another 10 years! my wife and kid used this and could have crashed them both! frame rusted from inside out and dealer deemed undriveable this week! truck valued at $13-15,000! dealer wont warranty and not under tacoma and sequoia recalls! same frame issues toyota! recall the 4 runner toyota! major danger of frame looking ok from outside but crumbling and falling apart while driving. have been a mechanic and body person all my life and never seen rusting and crumbling of a frame in chunks falling off! wake up toyota, recall the 4runner or fix my frame! cannot drive truck!

Tl* the contact owns a 2006 toyota 4runner. while driving 30 mph, the brakes failed to operate properly. the vehicle was towed to ira toyota of tewksbury (468 main st, tewksbury, ma 01876, (978) 863-9009), but was not diagnosed or repaired. the contact also noticed rust on the frame. the dealer informed the contact to call the manufacturer. the manufacturer was made aware of the failures. the vin was not available. the failure mileage was 100,000.

I own a 200y toyota 4runner, 4x4 4.0 v6 truck, and during the spring time i began to notice copious amounts of rust scale falling from my truck over night. i just thought this was surface rust/paint falling off, continued to drive for a week and began to hear creaking noises coming from the rear of the vehicle. i too a look underneath and saw that the right rear lower control arm mount is almost rusted through and the frame on the passenger side from the lower control arm mount back to behind the center of the axle is rusted through completely. i checked for recalls and found none for my model but did for similar year tundra, sequoia, and the tacoma which is a shared design with my 4runner. my truck has been waiting for a frame repair at a aftermarket body shop for over 4 months. i have contacted toyota customer care and received no help. i recently searched hoping to find new information and found that the nhtsa has opened an investigation on the frame rust issue. i am writing this to let you know this is a real issue and needs a frame replacement recall. a 2006 model year truck should not need a frame repair from rust after 12 years of existence and i believe toyota is negligent in recalling all other truck based vehicles for frame rust while trying to cheap out and exclude the 4runner. due to vehicle being in shop i do not have pictures, but i can get them if needed and also toyota customer care should have the record of me contacting them and sending in pictures earlier this year. thank you! 1804271716 is the toyota care case number.

Frame rusted and gone. terminal. cause us to run off the road. in motion on highway.

The frame of my 2006 4runner has excessive corrosion and rust. there are areas where the metal has become very thin, and more and more metal keeps flaking off all the time. i have already noticed a couple of holes through the frame rails. i'm especially worried about the areas where suspension components bolt up to the frame, those areas show severe rust and corrosion.

During recent maintenance of my 2006 toyota 4runner with 115k miles, a mechanic notified me that the frame crossmember in front which attaches to the control arms was completely rusted through and was a significant safety concern. the vehicle was brought to the toyota dealer to assess condition of the frame. the dealer stated the frame was irreparable and was not covered by a recent toyota frame recall for tacomas, tundras, and sequoias. the premature corrosion of the frame poses significant danger to drivers and could result in dangerous failures.

I bought my vehicle used with 86,000 miles on it. not even a year later my power steering return line rusted through and would not hold any power steering fluid at all. i replaced the power steering return lines with after market rubber line. i figured this out while i was driving and my power steering gave out. luckily it happened in a situation where it wasn't an immediate danger. next on the list was the muffler from the catalytic converter back. i noticed that it was excessively loud while driving . i went under the vehicle only to realize the the part of the muffler that connects to the catalytic converter was completely rusted through just hanging there! i just brought my vehicle in to get the underside completely coated with fluid film and my mechanic kept making reference to the 'rusty toyota 4runner ', didn't give me a warm feeling about the rest of the lifespan of the frame. it has 100,000 or so miles on it and i'd lime to have it for many more!

Tl* the contact owns a 2006 toyota 4runner. the contact was notified by a mechanic that the vehicle was severely rusted. the dealer and manufacturer were not contacted. the vehicle was not diagnosed or repaired. the failure mileage was approximately 111,000. *tt consumer stated transmission line failure. updated 11/26/18*jb

Took the vehicle into the toyota dealership, they said the frame was rusting heavily in one spot only, in front of the rear trailing arm mount on the left side. the trailing arm mount is ready to break off from the frame.. the vehicle has been cleaned weekly it's entire life, and is stored in a garage every night. the frame on this truck is almost exactly the same as the frame on the toyota tacoma which was recalled for this exact same problem.

Tl* the contact owns a 2006 toyota 4runner. while driving 35 mph over a bump in the road, the steering failed and turned in the opposite direction without warning. the vehicle was towed to the dealer (classic toyota located at 8510 tyler blvd mentor, oh, 44060) where it was diagnosed that the frame failed due to corrosion and needed to be repaired. the vehicle was not repaired. the manufacturer was made aware of the failure and suggested that the frame be repaired. case number: 1706140790 was provided. the failure mileage was approximately 140,000.

Serious frame rusting and/or rot noted on my 2006 4runner sport edition. in my opinion this is very unsafe as frame can become unstable while driving and cause an accident.

I,along with 48 other people, have posted to this forum that the frame on their 4runner had rusted and/or cracked. add mine to the list. my mechanic used the word "terminal" in response to the condition of my frame. it's not fully on its death bed, but it likely won't be driveable after 6 months.

The frame, heat shields, skid plate and rear axel are severely rusted. we've owned the vehicle since 2008 and it has been garaged and kept clean. the rust is reaching a point where we're concerned about the safety of the vehicle. we've noticed it coming on for about a year - now it's growing exponentially. apparently the toyota tacomas have been recalled, but not the 4runners. why!?

We have just been informed that the frame of our 2006 toyota 4runner is completely rusted out. this happened while i was driving down the road. this caused the control joint to come loose, and giving me very little control over the vehicle. the rust is an issues...and a huge safety hazard. i was able to get the car to the side of the road, and call a tow truck, but had this happened driving down the express way i cannot imagine the end result. toyota is aware of the rust issues. they have great vehicles that will run forever if you take care of them, but this issue is not a care issue - is a manufacture issue.

?purchased car in boulder 3/22/2017 ?2006 toyota 4 runner vin # [xxx] ?rust damage / dealer stated rust was because car was from ny, but would not get worse and was just superficial rust. ?purchased car and set an appt. with pueblo toyota 3/24/2017 to mount spare tire and do an inspection ?toyota could not mount spare tire and stated vehicle was in good condition except for severe rust damage, could not install spare tire, and informed me that it may cost double to do repairs in the future because of rust damage. ?took car to pro-masters auto body shop on 3/24/2017 and they informed my son that the rust was severe and they would not attempt to repair, but estimated costs to repair the rear end to be $6,000 to $7,000 ?reviewed on internet and there were several complaints about rust damage on 2006 toyota 4-runners, tundra?s, and tacoma?s from n.e. states. comments were also made that the vehicle with severe rust damage could be unsafe to drive. ?took car to individual who restores cars and he said the rust was so severe and car was not worth repairing and unsafe and he would not let his wife or family drive it. ?took car to custom care repair shop to review rust and install spare tire and they concurred that the rust was severe and unsafe and could not install spare tire. ?i called pro-masters auto body shop to confirm what they had inspected and if i could give his name and phone number if asked. ohe informed me that rust was so severe that if he attempted to secure spare tire, that the frame holding it was so thin he could not guarantee it would not fall off. ohe also informed me that as the vehicle gets wet the frame becomes weaker and could start to crumble. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

I recently purchased my dream car a 2006 toyota 4 runner. i purchased the vehicle in colorado but it was originally from new york. the vehicle has very low miles and rust damage, but the dealership at no surprise was not looking out for my best interest and did not inform me how bad the rust damage is and it may cost more than i can afford to fix it at all. currently i am not able to attach the spare tire because of the rust. i don't know how severe the rust damage is. pueblo colorado repair shops are not experts in this area because they do not see this type of damage very often.,i don't know if you help people that have the same problems that i do but if you can help in any way since you are also passionate about your dream cars i thought it would not hurt to ask if you can help in any way to fix or advise me on what i should do. a response either way would be appreciated

Tl* the contact owns a 2006 toyota 4runner. the contact stated that the frame of the vehicle was rusted and corroded. the vehicle was taken to the dealer where it was diagnosed that the frame needed to be replaced and the vehicle was unsafe to be driven. the vehicle was not repaired. the manufacturer was notified of the failure. the failure mileage was 62,584.

4runner has been garage kept, and the exterior looks perfect, lost all brake fluid, mechanic put on lift and found left rear brake line rusted through and then pointed out that the frame is severly rusted and would not pass inspection. trailer hitch, will fall off if i try and use it. box frame is rusted out on the bottom from front of vehicle to the very back. my wifes 2000 lexus suv has no rust on frame and drives the same commute each day as me.

Abnormal rusting of the frame and undercarriage.

On my 2006 4runner, i have been noticing an excessive amount of rust build-up on the frame and many of the undercarriage parts. this 4runner has spent it's whole life in colorado, we don't see rust problems here. i have never seen a vehicle have this kind of rust. i'm very concerned about the safety and integrity of it!

I currently own a 2006 toyota four runner that is not currently involved in a toyota recall for excessive rust. my vehicle is at a toyota dealer, a claim with toyota has been filed, and pictures of damage are being taken per my claim. i just received a call from toyota corporate claims department telling me that my toyota is not under recall even though i have excessive rot (not rust) that has eaten through my vehicles rear crossmember. currently my vehicle is un drivable due to this issue, my rear axle is only held onto the vehicle by two out of the four anchor points this posing a huge safety concern if the rear axle becomes separated from the rest of the frame. the front two mounts (that are welded to the rear crossmember) are torn completely from the rear crossmember, toyota says the body of the truck will need to be removed from the chassis in order to slide the new crossmember in but they refuse to cover this repair. as i'm sure you're aware but the 2004-2010 toyota tacoma are currently under recalls for this type of issue and the four runner shares this type of frame, and many other parts because it is assembled on a tacoma frame, but built in japan not in the us. toyota says that the recall only covers us made vehicles and japanese built units like the four runner, are not covered. please advise as i currently own a very expensive lawn ornament at this time and would like to see these units integrated into the tacoma recall process. thanks for your help.

Went to the toyota shop after getting a new transmission was replaced, they noted "cust not front frame core support is rusted off found a hole in the left frame rail". they also had to use new bolts for transmission due to corrosion on undercarriage. would not pass inspection until fixed. the frame is washed off continuously after being exposed to salt in winters.

Tl* the contact owns a 2006 toyota 4runner. the contact noticed excessive rust on the frame of the vehicle. the manufacturer was made aware of the issue. the vehicle was not repaired. the approximate failure mileage was 100,762.

Excessive rust on the frame and underbody components of my vehicle. my fear is that this rust will eventually lead to failure of key frame structural components.

The entire underbody of my 4runner has a severe amount of rust and corrosion. i have attempted treating the rust with rust converter and wire brushing to no avail. i am concerned about the rusted out components and the effect it will have on the vehicle.

Rear axle detached from vehicle due to severe rust. severe frame rust - dealer deemed unsafe to drive.

Noticed rust on garage floor,had dealer inspect the frame was told that , only found surface rust no holes. at what point does this turn into a safety problem, my husband and i are very concerned ! the vehicle was purchased new and was always parked in a insulated attached garage. this vehicle has only 45,000 miles, the body is in good shape.toyota had previous frame rust issues,we would hope toyota would replace the frame or buy this vehicle from us ,if we traded it in who would want to buy it with this rusty frame and ,what would we get for it?

The frame broke on my 4 runner when i was backing up and front tire fell inward. the truck had just under 100,000 miles. i spent approximately $7,000 for a body shop to replace the broken frame with a used frame. toyota must not have used a suffiently hard enough metal or did not treat the metal with the proper finish for frame to break at such an early mileage. i have the receipt and detail for the work done by the body shop.

The front drivers side of the main frame under the vehicle broke due to excessive rust on the frame. as far as i know toyota has a large recall now on rav 4s and lexus vehicles due to excessive frame rust but there is no current recall on 4 runners. i would like to add my concern in hopes of leading to a recall on 4 runners built during similar time period. according to toyota they say this is an ongoing problem they are trying to address. but they have failed to recall the products that are dangerous. when the frame breaks, this is a deadly situation while driving. toyota offered me no form of reimbursement when i reported the problem to their corporate office(toyota case #[xxx]) filed with toyota over phone on 9-25-14. information redacted pursuant to the freedom of information act (foia), 5 u.s.c. 552(b)(6). *tr

Severe frame rust. this issue has now a safety related issue. toyota has a recall on other models same year. but yet nothing on the 4 runner. because it is a safety issue and toyota is ignoring it. this time for a class action suit..

Have a 2006 toyota with 94000 miles on it. took it in for a recent recall and told the entire frame is rusted and back of vehicle could just fall apart while driving. my research indicates that toyota has several issues with frames rusting although they have only recalled a few of their models. i have always taken my vehicle to the toyota dealership where i bought it for service and no one has ever mentioned any rust problem until now when it is apparently to late and the vehicle is no longer safe or drivable. i am extremely upset that my children could have been in this vehicle when the frame gave out. toyota really needs to do something before someone gets hurt. i am told there is no recall or warranty to assist us. *tr

In 2011, i noticed my 2006 4runner was rusting so i took it to the dealer who looked at in and said normal wear. now in 2014, parts of my 4runner are falling off, one heat shield fell off and the other one is rattling like crazy, the screws have rusted through. there is severe rusting, the entire under carriage, the latch to close the rear door, the brakes,the gas tank, the body has brown spots, the tire rims, the only parts not rusted are the plastic parts. i am afraid to drive my 4runner. i have had to spend thousands of dollars on repairs so far on a vehicle bought brand new. *tr

The frame of this 4runner is rusted due to weather condition of salt and snow up north. this should be a recall for these 4runners

We had the 4 runner service for oil change and inspection when they found the frame completely rusted through and none repairable we still have to make payments. *tr

Frame rust

In september 2012 i noticed paint blistering on the tailgate of my 4runner. i now (8/13) have rust through originating from the inside middle of the tail gate. i took the truck to my local body shop and was told that this was a common problem with the 06 4runner. it was caused by a sound deafening material on the inside of the gate. "the material gets wet and holds the moisture causing body rot". this shop has repaired other 4runners with this problem. i also own a 1994 isuzu trooper with no body rust that sits next to it in my driveway. i was told by the toyota rep (oakdale toyota in ny) that it was out of warranty and they could not help me. i also have extensive rust on the undercarriage. the truck has never been off road before. *tr

Tl* the contact owns a 2006 toyota 4runner. the contact stated that vehicle was taken for inspection where the mechanic informed the contact that there was a significant amount of corrosion and rust on the majority of the frame. there were also two areas where the frame had been previously welded and exhibited holes. the mechanic advised the contact that the defect was as significant safety concern. the manufacturer was not notified of the issue. the current and failure mileage was 58,000.

Rarely driven, about 65,000 miles and the frame is rusting out. it started early.

This is a safety issue that seems to be on toyota models. the front and passenger doors will open if attempted to open during car operation even if the doors are locked. *tr

Tl*the contact owns a 2006 toyota 4runner. while driving at an unknown speed, the brakes failed. the vehicle was repaired by a mechanic. when the vehicle was retrieved, the contact noticed that the frame was rusting and deteriorated enough to cause a crack in the brake line. the current and failure mileages were 120,000.

Frame rust- structural issue
