2013 Toyota Fj Cruiser

Please consider opening or expanding an investigation into frame, underbody, brake-line, and suspension-mount corrosion affecting Toyota FJ Cruisers. I own a 2013 Toyota FJ Cruiser 4WD. A professional inspection found multiple fluid leaks, heavy rust, rusted exhaust, leaking rear shocks, and brake line/hose concerns. After reviewing the condition, the mechanic essentially declined to repair it and recommended scrapping the vehicle. The attached photos show conditions that appear safety-relevant: rust perforation through underbody structural metal near a bracket/crossmember area; severe corrosion around brake lines and fittings; widespread scaling near suspension and frame components; a leaking rear shock; and badly deteriorated exhaust connections. This is not just appearance rust. Also note the contrast between the observable condition of the vehicle versus the problems hidden beneath. This rust is clearly outpacing normal wear and tear. The safety risk is straightforward. At interstate speeds, a corroded brake line could fail during emergency braking. A weakened shock mount, suspension bracket, or crossmember could fail when the vehicle hits a pothole, uneven bridge plate, or highway debris. In dense, aggressive traffic, especially where vehicles travel 70+ mph, any sudden loss of braking, stability, or rear-end structural integrity could cause a spinout, rollover, or multi-vehicle crash. I understand Toyota has previously addressed severe corrosion on other truck platforms. I urge NHTSA to review whether the FJ Cruiser has a similar pattern of premature or excessive structural corrosion. Owners may not know the vehicle is unsafe until a mechanic refuses repair or a component fails. Please review consumer complaints, inspection photos, and corrosion-related failures before this becomes a fatal incident.

I purchased my beloved 2013 FJ Cruiser from Wellesley Toyota 6.5 years ago and have really enjoyed it. I have had it serviced religiously at McGee Toyota of Hanover since my purchase and expected to continue to enjoy it for many years to come and was just informed by McGee Toyota that the frame is severly rusted out throughout. My truck only has 158K miles on it and I expected this to last at least twice as long. This appears to be the same issue Toyota experienced with the Tundra and Tacoma with premature rusting on their vehicles due to a manufacturing issue. There are numerous complaints online about this issue and even a current class action lawsuit. I have alerted Toyota Corporate of this and they are not standing behind their product.

The contact owns a 2013 Toyota FJ Cruiser. Upon having the vehicle inspected by a State Inspector, the contact was informed that there was significant corrosion on the undercarriage of the vehicle. The contact took the vehicle to a dealer and was informed that the corrosion failure was a result of normal wear and tear. The contact was referred to an independent mechanic who specialized in vehicle undercoating to prevent further corrosion damage to the vehicle. Despite the vehicle being treated for the corrosion damage, the contact was recently informed that the corrosion damage had worsened, and that the vehicle was unsafe to drive. The manufacturer was notified of the failure; the contact was referred to the NHTSA Hotline to report the failure. The vehicle was not repaired. The failure mileage was approximately 80,000.

I went down the road & hit a bump my car rocked a little so I stopped to check the lug nuts & see if anything was wrong. I did not see anything. So, I continued to go pick my friend up as I was driving down the freeway anytime I hit a bump the car rocked more the faster I went. So I slowed down & watched traffic around me. Picked my friend up, went on the ramp and hit another bump and bam, my vehicle went so high up in the air my friend thought we were going to roll over. I immediately got off the freeway & there was a dealership right there. I asked if they could look at it & they wouldn't, they were too busy. I managed to baby it all the way back to my dealership. They said the control bar came away from the frame that was rotted. I called my insurance co. they said nothing they could do because of wear & tear. They did not view anything but pictures. I called claims & they said my VIN has no recalls that they won't do anything. They did not look at anything. I asked that they call my dealership to have them tell them how serious this could have been. They said my warranty was up in July of 2021. I had no letters to tell me this. I have only had it serviced at the dealership when it was due for service, nowhere else. I found out claims previously have been paid through a lawsuit on frames. Frames should last longer than this even in inclement weather. I also had it fluid filmed. Nobody will do anything & it's scary. Sad they want an accident before they look at things. I hope you can address this some way. Thank You.

Some 2005 – 2026 Toyota vehicles that have undergone water intrusion may exhibit a condition in which a musty odor is present. Follow the procedures in this bulletin to remediate the odor and address this condition. The purpose of this Service Bulletin is to provide general guidelines and procedures for odor remediation. This Service Bulletin provides a guide on how to prepare and treat the interior of the vehicle for odor remediation. Refer to the applicable model and model year Repair Manual and the EPA (Environmental Protection Agency) website for the most up-to-date safety and precautionary guidelines.

The air conditioning dye injection tool kit has been developed to aid in identifying the location of air conditioning refrigerant leaks. The procedures outlined in this Service Bulletin aid in locating, inspecting, and repairing refrigerant leaks.

Acid rain results from rainwater or other airborne moisture that become acidic due to industrial chemical impurities in the atmosphere. If these acidic compounds settle on an exposed vehicle, especially the horizontal areas such as the hood, roof, and decklid, significant damage to the painted surfaces can occur. Acid rain damage can typically be identified on vehicles by the presence of stains on the paint surface that resemble hard water spots. Unlike water spots however, acid rain damage cannot be removed by regular washing procedures. Also, because acid rain can etch and soften the paint, normal buffing or polishing repair procedures should not be attempted. This can cause further damage and result in visible depressions in the paint surface. The following are the three major categories of acid rain damage: •Minor damage: requires only buffing to repair. •Moderate damage: usually requires neutralizing, color sanding, and buffing. •Severe damage: extending beyond 1/2 mil of clearcoat on a pearl, metallic, or solid color, requires neutralization, sanding, and repainting. In cases where acid rain damage is minor, neutralization and buffing with a liquid-type paint finessing product may provide an adequate repair. Only specially formulated products outlined in this bulletin should be used for that purpose. Unfortunately, other than minor damage, there is no simple method of determining the actual extent (depth) of acid penetration other than color sanding a representative affected area until there is no visible etching or depressions, followed by measuring the amount of paint removed with either a magnetic or digital-type film thickness gauge. The procedures in this bulletin are intended for use by qualified body/paint technicians and should not be attempted by inexperienced personnel. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. Perform frequent vehicle washing, as often as daily, during high heat and humidity periods to minimize the potential for paint damage due to acid rain exposure. This is especially important in geographical areas known for high frequency and concentration of acid rain and industrial fallout.

To prevent brake rotor rust from forming during transportation and storage, wheel film will be used instead of a cardboard type of anti-rust cover. The purpose of the wheel film is to shield the disc brake rotor from weather elements and initial rust before the vehicle is delivered to the customer. Consequently, the film should remain on the wheel for as long as possible.

The condition known as acid rain is caused by airborne chemicals or particles in the atmosphere, which mix with rainwater, nighttime dew, or high humidity to form acidic compounds. If these contaminants settle and remain on a painted vehicle surface, especially the horizonal areas of the hood, roof, and decklid, significant damage can occur. This damage is the result of actual etching of the paint and appears as pitting or water spots. As acid rain droplets on the vehicle surface evaporate, the concentration strength of the acid increases, causing deeper and more rapid damage. This evaporation and corrosive action also occur more rapidly on dark colored cars as direct sun heat increases. It is the dealer’s responsibility to protect and maintain the quality of the vehicle’s paint finish after receipt at the dealership prior to the first sale. In areas known for high frequency and/or concentration of acid rain, frequent vehicle washing during high heat or humidity periods will minimize the potential for paint damage caused by acid rain. It is further recommended that either reverse osmosis or deionized water be used to prevent water spotting.

Toyota vehicles are currently protected with RapgardTM protective film designed to protect the horizontal painted surfaces. This material protects from acid rain, environmental fallout, and rail contamination. Follow the Removal Procedure in this bulletin to remove the RapgardTM protective film within 90 days from initial application.
