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.

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.

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!

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.

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?

  • 105,000 miles
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).

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.

problem #2

  • 45,000 miles
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.

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.
