2006 Toyota Sequoia

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.

IN A LETTER DATED JANUARY 18, 2007, TOYOTA NOTIFIED NHTSA OF A SAFETY DEFECT IN MODEL YEAR (MY) 2004 THROUGH 2006 TOYOTA TUNDRA AND MY 2004 THROUGH 2007 TOYOTA SEQUOIA VEHICLES PRODUCED BETWEEN SEPTEMBER 15, 2003 AND NOVEMBER 17, 2006 (NHTSA RECALL NO. 07V-013). ACCORDING TO TOYOTA, ?IN THE FRONT SUSPENSION LOWER BALL JOINT ON THE SUBJECT VEHICLES, DUE TO POSSIBLE IMPROPER FINISHING OF THE BALL JOINT, SUCH AS THE ASPECT OF THE BALL STUD SURFACE, SOME BALL JOINTS MAY EXPERIENCE AN INCIDENTAL DETERIORATION OF THE INTERNAL LUBRICATION. THIS MAY CAUSE THE BALL JOINT TO WEAR AND LOOSEN PREMATURELY, WHICH COULD RESULT IN INCREASED STEERING EFFORT, REDUCED VEHICLE SELF-CENTERING, AND NOISE IN THE FRONT SUSPENSION. IN EXTREME CASES, IF THE VEHICLE IS CONTINUOUSLY OPERATED IN THIS CONDITION, THE LOWER BALL JOINT MAY SEPARATE FROM THE KNUCKLE AND COULD CAUSE LOSS OF VEHICLE CONTROL.?TOYOTA WILL INSTRUCT OWNERS TO RETURN THEIR VEHICLES TO ANY TOYOTA DEALER FOR REPLACEMENT OF THE FRONT SUSPENSION LOWER BALL JOINTS. THIS ENGINEERING ANALYSIS HAS BEEN CLOSED, AS TOYOTA IS RECALLING THE AFFECTED VEHICLES.ODI WILL MONITOR THE EFFECTIVENESS OF THE REMEDY AND TAKE FURTHER ACTION IF WARRANTED.

This Toyota has several large rust holes directly on the frame. i hit a pot hole and more structure damage was revealed on the frame from rust. The truck drives rough now. The vehicle only has 150,000 miles. The rust holes are so severe that they're directly under my suspension. I feel very unsafe driving this vehicle. Their was once a recall for the frame. It doesn't seem that it was satisfied. I'm very worried about this issue. Toyota should have to replace frame or make it safe to drive.

My vehicle was in dealer shop for various maintenance 3 times (Nov 202 - May 2021 - Jan 2022). Frame rear passenger side rusting to the point I was told not to drive my vehicle on bad roads. Toyota dealer said to replace the frame thru them would cost me $14,000. I cried all the way home because I take exceptional care since I purchased her 2006 new. She is a Cream Puff. This should have been identified sooner. I have not driven her since Jan 3, 2022 because not only me+ (husband & dogs), but also my fellow motorists are at risk. Both my husband & an employee of the dealer shop asked Toyota directly in attempt to get them to replace frame at their expense. Toyota said No.

The driver side, rear, trailing arm broke away from the vehicles frame due to “frame rot” while driving. The vehicle became extremely dangerous to drive. Toyota has since declined to help. They said they notified us via mail of a customer service campaign addressing the premature rust issue, but we never learned of the program and lawsuit until after the frame broke and I almost crashed. Later I saw the broken arm/frame under the vehicle. This frame failure can potentially be a catastrophic and deadly event. I opened an insurance claim and it was denied and I was referred back to Toyota. Our vehicle has been factory maintained it’s entire life. No service advisors ever mentioned a possible problem to my family and I. I recently spoke to the Toyota service manager at Parker Toyota in Couer d Alene Idaho and his master technicians have seen the same failure that occurred on our vehicle. This is extremely dangerous.

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.
