Extreme Rusting on the frame undercarriage of the vehicle. Our mechanic found it today - said it must have been rusting for years & that this is a common problem with 03 - 05 Toyota 4Runners.

Unaware of frame rusting issues to vehicle.. Observed rust through carpet on driver side. Upon research safety is a concern. Due to high volume of this type of issuing occurring a safety recall should be issued. It was not verbalized at time of purchase the make and model of vehicle have these type of issues. Especially, when this issues had been occurring prior to purchase of this vehicle.

The frame is rusted through on this 4Runner. Same frame as the tacomas that were recalled and I-??m wondering why Toyota wouldn-??t recall THE SAME EXACT FRAME WITH MAJOR RUST ISSUES on a different platform. This truck is not abused so it-??s very frustrating to see it falling apart at the frame when everything else is intact and solid. The rot on this frame is inevitable. I-??m going to be very upset if I have to pay out of my own pocket for something that should be 100% covered under recall. This is a huge safety hazard and could lead to serious injury or death.

Took vehicle for service a couple of days ago. Mechanic would not work on the vehicle due to extensive frame rust and corrosion. Mechanic said he could push his finger through some of the rusted frame members. Extensive frame rust/corrosion on at least 3 sides of the vehicle and sagging frame in the front per mechanic.

Original owner of 2004 Toyota 4Runner SR5 (purchased February 23, 2004). Garage kept and approximately 125,000 miles. Vehicle was taken to mechanic for exhaust issues and reported the flange had rusted and disintegrated providing $2300 quote to repair. Taken to a second shop that indicated rust on frame and sub-frame was significant and would not accommodate an exhaust repair. Also stated that bolts and supports for radiator and gas tank were severely rusted. Estimates the car to be road worthy for an additional 3-6 months.

My Frame is a rusted mess. The entire frame is experiencing rust issues. My rear sway bar rusted off and broke into pieces (1/15/21). Now my exhaust pipe has fell off the muffler due to rust (7/21/21). My brake calipers have been very badly rusted as well as the pieces that hold my shocks and suspension in place. It has been progressively getting worse over the past 3-4 years. I feel like this has now become a safety issue and I'm not sure if it's safe to drive. It may be a risk to myself and other drivers on the road. My mechanic has told me that it will not improve and he thinks that the frame and other parts should be recalled. I have plenty of photos if needed. Please help me before something goes wrong.

My 2004 Toyota 4Runner has holes multiple inches in diameter rusted completely through the frame in multiple locations including where frame rails meet and are welded. This 4Runner is very clean and well kept in a climate controlled garage. The 4Runner was somehow not captured in the class-action law suit against Toyota that included the Tacoma, Tundra and Sequoia. Toyota has long known the frames are prone to excessive, premature rust corrosion because the frames were not properly prepared and treated against rust corrosion when they were manufactured and yet it has failed to offer significant help to owners. The excessive rust damage on my Toyota 4Runner compromises the vehicles safety, stability and crash worthiness because important suspension components, engine mounts, transmission mounts and body mounts anchor to the vehicles frames. I have spoke with a local Toyota dealer who stated they would inspect the vehicle with a diagnostic fee of $139 but that Toyota would not help with repair or replacement of the frame. There is no need to inspect the vehicle as I have multiple pictures illustrating the magnitude of the rust damage to the frame including several holes multiple inches in diameter in critical locations of the frame. I have attached several photos of the rust damage as well as photos of the body for reference to how well kept the vehicle is.

Last year the frame showed rust and holes and was rejected by the inspector. We were able to get the worst hole patched and it passed inspection. I am afraid the car might be unsafe.

On April 14, 2019, I was informed by an auto repair shop that my 2004 Toyota 4Runner showed signs of excessive rusting on the front end of the frame at the bumper and radiator support. The repair shop owner/mechanic indicated the bumper may eventually fall off. At the time, the odometer reading was only 117,834 miles. On June 22, 2021, I took the truck in to the Toyota dealer where I purchased it to have the regular oil change done and requested that they inspect the frame during the routine "Multi-Point Inspection." On this visit to the Toyota dealer, the truck's odometer reading was 141,595. The mechanic pointed out the more severe areas of rusting, which included the "Front right bumper support crumple zone area, also right side top under pass front seat area very thin." He indicated that the left side of the frame, although not as advanced as the right side, was also rusting, because water from wet roadways accumulates within the frame and does not drain. I was not able to take photos of the top under pass due to lack of access. However, the mechanic had me run my fingers along the top of the frame. The frame was so corroded that it was crumbling, and my fingers went right through the frame. Some areas already had holes from the corrosion. I have included both the repair shop and Toyota dealer's observation reports as well as the photos of the front end of the frame and the right side under pass. It was not possible to take photos of the top of the right side under pass, which the mechanic pointed out was the most affected. The vehicle is available for inspection if necessary.

On April 17, 2019, I was informed by P.R. Auto Repair that my 2004 Toyota 4Runner showed signs of excessive rusting on the front end of the frame at the bumper support and radiator support. This observation was noted by the auto repair shop's owner. It is important to point out that my truck had only 117,834 miles on its odometer and should not already have had such a serious rusting problem. My truck was in for replacement of rear pads and rotors and was on a lift when the problem was noted. At the time the problem was being pointed out to me, a portion of the rusted metal in that area came right off. I was told that eventually the bumper could fall off and potentially lead to increased more dangerous problems. I have taken my 4Runner to A-1 Toyota where I purchased the vehicle for the regularly scheduled oil changes. "A-1 Toyota Quality Vehicle Inspections" were conducted each time with issues that required further attention noted in the report, but the rusting problem has never been included in the reports or pointed out to me. The truck now has just over 141,240 miles on its odometer and the corrosion problem has become significantly worse and my safety and the safety of others has become a growing concern to me. I have included a scanned copy of the April 19, 2019 invoice/receipt from the P.R. Auto Repair shop. The observation of the problem is noted under the Instructions section. I have also included two photos (one of the left side view and one of the right side view). The vehicle is available for inspection upon request. I understand that there is currently an ongoing investigation related to excessive rusting on Toyota 4Runners' frames. It is my hope that my 2004 Toyota 4Runner can be recalled for this problem as were other makes of Toyota vehicles that suffered the same problem before mishaps or tragedies occur as a result.

Severe rusting of body frame

- Chanhassen, MN, USA

The frame is rusted very badly and may need to be salvaged. Many of the other Toyota vehicles in this same year which have the same frame have already been recalled. Why not the 4runners? I've owned many other early 2000's vehicles and none have had this bad of rust. Simple not acceptable and not safe!

Our 2004 Toyota forerunner with V6 engine was purchased as a used vehicle in 2019 with 106,000 miles on it. Since then, it has developed more and more areas of rust on the frame despite our efforts to mitigate this issue. We have had to repair the frame, suspension, brakes, and wheel bearings. We continuously inspect the undercarriage and continue to discover more and more areas of significant rust/deterioration despite efforts to clean, treat (with paint, rust inhibitors, welding repairs). We are concerned that this deterioration will soon result in a catastrophic failure and possible accident resulting in property damage, injury, or death.

The original frame on our car is almost completely rusted. There are holes in the frame and complete corrosion along the side beams. This is a huge safety hazard while driving. There is so much rust on the underbody. All parts are completely stock and original. This should not be a process we have to pay for as it is a major safety concern that Toyota is completely overlooking. The holes in the frame are about a baseball size whole. I have taken it to over three mechanics and a body shop recommended from Toyota and each of them said the frame is almost entirely unsafe.
