2011 Toyota 4Runner

From 2000 through 2017, Takata produced millions of air bag inflators using two types of phase-stabilized ammonium nitrate ("PSAN") propellant -- propellant 2004 and propellant 2004L. After prolonged exposure to high temperature cycles and humidity, inflators using propellant 2004 can degrade, causing the propellant to burn too quickly when ignited. The rapid burning can cause the inflator to rupture during deployment, potentially causing serious or even fatal injury to vehicle occupants. See 2016 Blomquist Report at www.nhtsa.gov/sites/nhtsa.gov/files/documents/expert_report-hrblomquist.pdf.Consequently, all frontal inflators using propellant 2004 that do not contain a "desiccant" (a substance that traps and holds moisture) in US vehicles are under recall. These "non-desiccated" inflators either have been or are required to be replaced.In some cases, the remedy part for these recalled inflators was, or will be, an inflator using either propellant 2004 or 2004L that does contain a desiccant. None of these "desiccated" remedy parts (which were installed in older model year vehicles) are currently under recall for a degradation concern. Certain subsets of desiccated PSAN inflators using propellant 2004 for use as original equipment, however, have been recalled for a degradation concern. All Takata inflators produced with propellant 2004L contain desiccant, and none of these desiccated inflators using propellant 2004L are under recall for a degradation concern. There have been no reported field ruptures in any non-recalled desiccated PSAN inflators.It is understood that desiccants fully saturate at some threshold, at which point any additional moisture will not be captured. This means the degradation process observed in non-desiccated inflators using propellant 2004 may also occur in non-recalled desiccated inflators using propellant 2004, assuming additional moisture enters the inflator and high temperature cycling occurs. Based on available information, desiccant saturation can occur within the first five years in the worst environments, and the time required for full saturation is affected by multiple factors. While no present safety risk has been identified, further work is needed to evaluate the future risk of non-recalled desiccated inflators using propellant 2004.Three entities -- Takata (now known as TK Global), the Independent Testing Coalition, and Exponent -- have been studying the long-term behavior of Takata desiccated PSAN inflators using propellant 2004L (as well as 2004) in the presence of moisture and temperature cycling. The research efforts, which include development of predictive modeling techniques and field sample analysis, are ongoing. To date, none of the researchers have identified field evidence showing that propellant 2004L is undergoing a degradation process that leads to aggressive deployment and potential rupture. However, the time in service of such inflators remains short compared to that of the inflators using propellant 2004. Further study is needed to assess the long-term safety of desiccated inflators using propellant 2004L.The Office of Defects Investigation is opening this investigation to examine whether a safety defect related to propellant degradation exists in non-recalled desiccated PSAN frontal inflators manufactured by Takata. This investigation will require extensive information on Takata production processes and surveys of inflators in the field. Lists of recall actions that may have used desiccated PSAN inflators as remedy parts, as well as the makes and models originally manufactured with them, is available with the downloadable version of this document (see nhtsa.gov/recalls?nhtsaId=EA21002 -- note this information is subject to change/revision as the investigation proceeds). This investigation does not supersede EA15-001, which remains open.

I am writing to report a serious safety hazard regarding the factory paint and primer on my 2011 Toyota 4Runner (Paint Code: [ 070 for Blizzard Pearl]). The vehicle is experiencing severe, widespread paint delamination where areas of factory paint are peeling cleanly away from the metal body panels while driving. This is a known manufacturing defect involving a chemical failure of the factory primer, which Toyota previously acknowledged under Customer Support Program ZKG. This manufacturing failure has created distinct, immediate safety hazards on public roadways. Blinding Glare / Driver Distraction: Because the paint has completely peeled away in sections on the hood, the bare, highly reflective eco-coat/metal underneath is completely exposed and getting worse day by day. During peak daylight hours, the sun reflects off these large exposed areas directly into my line of sight, causing sudden, blinding glare that severely impairs my vision while operating the vehicle. Toyota has refused to remedy this manufacturing defect case number : 260612000716, citing that the vehicle is outside of their arbitrary calendar-based extension program (ZKG), despite the fact that the underlying chemical failure and resulting safety hazards remain active and dangerous.

Received a letter about recall letter about peeling paint. Paint was ok at time of letter. A year later the paint is now peeling from every panel. Toyota says the campaign has ended and there is nothing they can do. But customer relations also said there are many people calling in after the fact with the same peeling problem. I would like Toyota to repaint the vehicle because they are aware that they have a problem. I will be trading my vehicle in for a new one in a year and my vehicle will not be worth anything in its current shape. Thank you

The paint on the outside of my 2011 Toyota 4Runner has recently been peeling significantly in various areas of the car, including the roof, the door below the window, and the front driver side panel. These areas are prone to rust, and many inhibit the safety of the car due to rust. Due to living near the ocean (within a mile), the salty air may increase the rust due to the paint peeling in various and significant areas of the car.

The Blizzard Pearl paint on my Toyota 4Runner is peeling in large patches, exposing the undercoat and compromising the vehicle’s integrity. Toyota issued a Customer Support Program (CSP) acknowledging this as a known defect affecting Blizzard Pearl paint, but I never received the notification. As a result, I missed the deadline to have the issue corrected, and Toyota has refused to assist. This widespread issue impacts resale value and could potentially lead to rust or corrosion. There should not be a time limit on addressing a manufacturing defect of this nature. Toyota should be held accountable for providing a lasting remedy, especially when customers like me were unaware of the CSP timeline.

Brakes ABS system failure affect the rear traction not feeding the brakes rear lines could be related to the proportioning sensing valve or other devices and the dealer says that the part it’s discontinued and service center says that the part cost around $2,000 plus labor. It’s very dangerous that someone have this issue on the road.

I was driving my truck and needed to use the horn to warn another driver of a potential collision. My horn did not work. I later noticed that the horn only stopped working when the steering wheel was in the forward position. I researched this online, and it was stated that this was a known issue with many Toyotas including the 4runner. It is the clock spring in the steering wheel which needs replacement. Another issue is the price Toyota is charging for the clock spring at $800 which may deter customers from fixing it. I am fixing mine and ask for nothing except consideration in forcing a recall. This is dangerous. I can send you the defective clock spring if you would like it. I bought the vehicle but live in Canada.

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.

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.

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.

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.

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.

Vehicles may occasionally be subjected to contamination by airborne iron particles shed from railroad tracks, train wheels, exposure to heavy machinery facilities, grinding, welding, etc. This type of contamination can be identified by the presence of small, red or brown particles on the paint surface. These particles are often difficult to see on dark color paints but can be easily felt when brushing a hand across horizontal body surfaces such as the hood, roof, or deck lid. Follow the Repair Procedure in this bulletin to clean vehicles that may have been subjected to contamination by airborne iron particles such as rail dust during rail transportation or extended storage near industrial areas.
