Odometer Fraud. The contact investigated a 2003 Toyota 4 Runner. The contact stated that during the investigation, he discovered a fraudulent scheme of approximately 15 vehicles with odometer fraud. The contact stated that the suspects targeted Facebook Marketplace victims by spraying oil on the engine prior to test-driving the vehicle, and when the vehicle began smoking, the suspects would ask for a discount for the vehicle. The contact added that after the vehicle was purchased, the odometer was rolled back and the vehicle was resold. The vehicle was a private sale. At the time of purchase, the vehicle mileage was 150,000, and at the time of the vehicle being sold, it was discovered that the mileage was 306,000.

While my mechanic was servicing a small exhaust leak on my vehicle he noticed that the chassis/frame of the vehicle was heavily corroded. He told me that he believe it was no longer safe to drive and that I contact Toyota. I had a local Toyota service center also look at it and they confirmed that the chassis/frame was heavily corroded and unsafe to drive.
My vehicle: 2003 4Runner SR5 2WD VIN: [XXX] Issue: Front driver's side door will not open. Electronic locks are operating, but the door release is not functioning. Safety Concern: What if I was in a situation where I did need to get out of the vehicle immediately? Such as a high-water incident, fire, etc. Especially for a person [XXX], as myself, this would be a big issue. When attempting to exit the car after pulling into the driveway, I could not open the driver's door. The locks would release, but the door latch would not. I had to crawl over the console to get out through the passenger side. This was not easy as I had back fusion surgery and 8 disc replaced, fused. I had to open the sunroof to help with get over and out. After I did get out, I tried the key in the driver's door, it would actuate the door locks on all doors, but the driver's side door latch would still not release. I even disconnected the battery and reconnected. No help. And after knowing more, it was not an electrical issue, but mechanical failure. I now have it at the repair shop after talking with Toyota Service manage who admitted it was a poor design as the repair for this is to destroy the door panel to get to the actuator to attempt to release the door latch. The estimate for this work is 1,150.00. I am beyond frustration, and especially when I see there is no recall for this issue. There are penty of conversations on this same issue on 4Runner forums as well as all over YouTube. Thank you for look

The VSC system in the vehicle becomes disabled due to a firmware 'glitch' identified by Toyota when an emission system issue is detected by the onboard diagnostic system.

I purchased this 2003 Toyota 4Runner in 2018 under what I assumed was prime condition, for a vehicle that spent the majority of its life in Nebraska/Kansas before I moved to Texas in 2021. At 87,400 miles at the time of purchase, the vehicle had no visible damage to the exterior besides a few paint chips, some minor hail damage and scratches, and some easily fixed surface rust in the paint on the tailgate. The previous owner had driven it leisurely and had kept the miles low after 15 years. The car has had some mechanical issues, but nothing out of the ordinary outside of some regular maintenance over the first few years. Being close to 100,000 miles, the timing belt and pump was replaced around 98,000 miles. Other issues have been fixed periodically, please reference the attached files. After joining a Toyota 4Runner 4th Generation Facebook group and seeing a post about another's issues with rust damage in October 2020, I decided to take a look at my own frame. I then inspected my own vehicle, and found significant frame rot damage. It is extensive, with significant rust to the frame, with large holes and soft patches that question the integrity of the frame and the safety of the vehicle on the road. Every time I hit a small bump or pothole, I fear the frame will crack and I will lose control as others have. I have not sought out professional repairs due to the extensive cost, and am awaiting the outcome of a current class action lawsuit by the Bell Legal Group. The 4th Gene

I am unable to steer the truck due to the intermediate steering column rust. The Tacoma was recalled for the same reason, I am assuming the 4runner has not been recalled because it was manufactured in greater numbers, and therefore more costly to repair, the danger of the severe rust is the same in both vehicles.

Excessive frame rust causing difficulty to keep vehicle on the road. No warning lamps, I noticed the rust starting years ago, now the rust is so bad that the frame is rusted through causing difficulty steering and loud crunch noises. I contacted Toyota Consumer Affairs explaining the rust concern and asked if I needed to take the vehicle to a dealership for inspection, they said it wasn’t necessary (sounds like they don’t want to admit the existence of a possible manufacturing defect). The vehicle is available for inspection. I feel like I would be doing a disservice to society if I continue to drive this vehicle on public roads due to the danger of injuring a pedestrian or another motorist.

The rust and corrosion underneath the vehicle continually gets worse year after year. The main components of vehicle relating to the engine, powertrain and suspension underneath vehicle are corroded; holes exist in the frame of the truck through out. The frame of truck is rotted due to not being sealed properly during the manufacturing process. Due to the rust and corrosion on the frame of truck, it is impossible to get work done on exhaust and muffler areas. I will send pictures for your reference. This makes driving a safety concern for myself and my son. At this time, I am unable to purchase a new car and do not have money to replace/fix the frame of truck. Inevitably, this problem will get worse and may cause a safety concern for myself and others on the road. I called Toyota on 4/12/22 and was told that there is not a recall for this issue and that any repairs would have to be paid by me. I then proceeded to call the number given to me by the representative to call 800-331-4331 for the Toyota Corporate office. I spoke to Blake who gave me the same answer, there was not a recall on this vehicle for rust/corrosion on the frame of vehicle. At this time, Toyota charges $150 just to check car and unfortunately, I don't have those funds to pay such a fee. I asked Blake if there was a way, Toyota can check without charging a fee and his answer was no.

Frame has major rust holes towards the front inside next to the catalytic converters. Hoping to get them repaired before frame failure. The frame design is similar to the 2005 to 2015 Tacomas, which experienced similar issues with rust damage causing frame integrity issues. Toyota had a program to replaced those frames, but not for the 4Runners. The issue seems to be caused by certain factory openings in the frame that allow road salt to enter into the frame cavity, and cause the inside to rust. Being next to the catalytic converter, the heat accelerates the rust. On my 4Runner, the issue has gotten worse in the last 2 years. I cannot understand why Toyota covered all other trucks/suvs that use this similar frame but ignored the 4Runner.

I thought I should take it to the closest Toyota dealership in Troy, Michigan for advice and they responded that the vehicle was beyond repair and that a new frame would cost around $20,000. I could not leave my car there, and risked driving it home, where it has been parked ever since.

The frame of my 4runner is so so rusted that my mechanic put his finger through a piece of the frame it is so unsafe for Mr and my grand children and EVERYONE ELSE on the road that it literally makes me sick. It'd the only vehicle I have so I have NO CHOICE but to drive it. It terrifying. It is available to inspect at anytime. I just bought this vehicle less than a year ago from a dealership and it so sad that they wld sell it to anyone knowing the frame was rusted its criminal in my opinion. It Is for sure a safety hazard to everyone. I hope that this investigation proves to help get all of these 4runners OFF THE ROAD. So that a preventable tragedy doesn't happen.

Really bad frame rust, holes in frame, engine mounts.... Cracked dash board. All problems shared by many 2003 4runner owners too. I'll take more photos.. Thanks for your attention.

Due to severe rust underneath the vehicle, there have been a few issues that have made the vehicle very unsafe to drive. Last week, both of my rear brake lines were completely done and leaking brake fluid leaving me with no brakes. This was due to rust and corrosion that had eaten the metal lines away. The radiator mounts are corroding, as well as the skid plate for my fuel tank and a few spots on my frame near the rear. I was not aware of the rust as I just got the vehicle a few weeks ago. I was driving in traffic when my brake light came on and I noticed my brakes didn't seem to be very effective and they eventually got the point where they were not working or slowing the vehicle at all. Once I took it to the shop and they put it on the lift, the mechanics pointed out just how bad the rust was.

No Accident - Items need to be investigated for Safety Defects on Toyota's. 1> Front Brake Calipers (constant freezing of the front brake calipers). 2> Dash Cover (excessive cracking on the dash covers especially areas that contain airbags). 3> Fuel Pump Connection (on top of fuel tank, connection to fuel pump appears to create a short, which in turn causes vehicle to stall also could cause a fire). 4> Excessive Frame Rust (frame has excessive rust outside and inside which is causing frame to fail. this is a manufacturing issue). These are ongoing issues with Toyota that have been reported and nothing is being done about it. Multiple 4runners are having big time Excessive Frame Rust, which are causing the frame coming apart during highway driving. These photo's show the rust on the outside and inside, all metal is having rust issues. Paint has been applied to cover said rust but it still reappears with-in a few months. Best way to contact me is via e-mail.

Car inspection at a service center revealed advanced rusting of the frame. I was told this could be dangerous.

The frame is completely rusted through and soon will be unable to support the steering, engine or drive train. The problem was confirmed to me by an independent service center that I have used for 10 years and I trust.

The frame has rusted almost completely through near the front upper and lower control arms near the cross member there. The passenger side is so bad the welder I took it too sad he couldn’t repair it without doing the crossmember section and all. The driver side is not at bad but doesn’t look to hot. The crossmember where the radiator sits is also starting to completely rot away

I heard a loud noise (scraping-dragging) from the bottom of the engine area while driving on the highway This was a very dangerous and scary incident Pulled over and My fiancé checked under the engine A very large metal piece was dragging the road I did not hit a bump or anything. A body shop mechanic informed me that the chasis of the 4 runner was in extremely bad condition The 4Runner will not pass inspection because of this condition I respectfully request help in this matter

Frame is rotted out and brake lines attached to the frame as well as every suspension component. Car failed inspection deemed unsafe to drive. This problem has been addressed for Tacoma, tundra and sequoia but not 4runner. These frames have the same issue as those and needs to be repaired by Toyota due to lack of rust and corrosion protection. There’s no reason 4runner should be overlooked for the same issue as the other full frame trucks.

Reading this record
Complaint volume is well above typical for a single model year.
Complaint counts track how many cars were sold and how long they have been on the road as much as they track quality. A common model from 2013 has had a decade to accumulate reports; a rare one from last year has not. The signal worth weighing is in the severity columns, in whether the same component keeps appearing, and in whether the manufacturer eventually opened a recall for it.
Recall repairs are free for as long as the recall stands. Check whether a specific car still has open work at NHTSA's VIN lookup.
Most recent recall on file: Feb 24, 2011. Source: NHTSA Office of Defects Investigation.
