2013 Toyota Highlander

On November 16, 2018, the Office of Defects Investigation (ODI) opened an Engineering Analysis (EA18-006) as an upgrade to a Preliminary Evaluation (PE18-005).  The investigation focused on allegations of steering wheel separation from the lower steering column after using the tilt and/or telescoping mechanism. Given the separation occurring when operating the tilt and/or telescoping function and failure of both shear capsules to maintain the lower steering column mounting position, potential for shear capsule damage in the known failures due to collisions, the overall low rate of occurrence, and the updated manufacturer documentation, this investigation is closed.  The closing of this investigation does not constitute a finding by NHTSA that no safety-related defect exists.  The agency reserves right to take further action if warranted by the circumstances. A detailed summary of the investigation is attached to this closing resume. To review the ODI reports cited in the Closing Resume ODI Report Identification Number document, go to NHTSA.gov.

On May 4, 2018, the Office of Defects Investigation (ODI) opened Preliminary Evaluation PE18-005 to investigate three allegations of steering column separation for Model Year (MY) 2008 through 2013 Toyota Highlander vehicles. Two (2) of the 3 complaints were received by ODI in April 2018 and occurred while the vehicle was in motion. Since opening PE18-005, one (1) additional VOQ involving steering column separation has been received. This incident occurred while the vehicle was stationary.As part of PE18-005, ODI examined the field data, warranty data, and relevant technical information submitted by Toyota in response to the PE18-005 information request letter. Ten (10) additional incidents of steering column separation were identified. Four (4) of these instances occurred while driving. During PE18-005, ODI confirmed that the steering columns in the subject vehicles are equipped with breakaway capsules that are designed to collapse/shear during certain types of vehicle collisions. This design feature aims to reduce driver injury severity from impact with the steering wheel in frontal vehicle collisions. There is no direct method for detecting when the capsules in the subject vehicles have sheared. If the driver operates the tilt/telescoping feature after the breakaway capsules have separated, the steering column may drop out of position and could subsequently detach entirely from the rest of the steering assembly. Loss of steering while driving may cause a loss of vehicle control, which could lead to a vehicle crash.To date, ODI has identified 14 incidents involving complete steering column separation, 6 of which occurred while driving. One of these incidents involved a minor crash. Additionally, there have been 16 events where the steering column dropped from the dashboard mounting brackets, but column separation did not occur. Four of these incidents happened while driving. Of these 30 total separation/drop incidents, 5 of the vehicles have evidence of minor collision repairs months or years prior to the steering column failure.This investigation has been upgraded an to Engineering Analysis (EA18-006) in order to 1) conduct a more detailed analysis of the conditions that may cause the steering column breakaway capsules to separate and 2) assess factors that may contribute to the problem of failing to detect and repair breakaway capsules after they have separated. Toyota has recently revised their repair manual and issued a Collision Repair Information Bulletin to help address the second concern.The VOQs associated with this investigation can be viewed at www.NHTSA.gov under the following ODI complaint numbers: 11141761, 11083623, 11083280, 10888043.

This is related to the Faulty Spiral Cable Assembly (HORN) that on line evidence suggests should have been a Toyota Recall item for this year and model. In 2014, Toyota issued a recall for 97,000 Hylanders for this very thing however it only covered 2008-2010 at that time. In review of safety recalls for faulty Spiral Cables on other Toyota models, it's evident they have had issues. On December 10, 2025, I replaced the Spiral Cable with a certified Toyota Dealer and worked to get reimbursement through Toyota by sending a certified letter and the replaced Spiral Cable to them to prove the evidence of the permanent, pinched cable assembly. According to the Toyota Mechanic, there is evidence the horn assembly was permanently 'pinched' at installation resulting in ultimate failure with the steering column use. I've owned several Toyota Vehicles through 200,000+ miles, including my 2005 Toyota Sienna and never have I had a horn become inoperable during ownership. Toyota responded there was nothing they could do to reimburse any portion of this and no recall warranted. I'm registering this complaint in hopes that other folks that have opined on line will have also reported this to generate a recall for this year/model given ongoing challenges with this Spiral Cable Assembly. A horn is an obvious needed safety feature and I've had this car serviced at Toyota dealers since we purchased it as a Certified car from Toyota in 2016. The cost of replacement was $694.86 to insure our safety and use of an alarm/horn for distracted drivers. My hope is that the NTSB will register this as a formal complaint so Toyota steps up to do the honorable thing to protect families. Thank you for your consideration

After a hard braking session because of a car that pulled quickly in front of me the ABS light and check engine light came on with a code of C1391 - Abnormal leak in Accumulator. A warning message came on the info center saying I needed to take it to the dealer to have the brake system checked for a serious issue. Went to the dealership and they replaced the Brake Actuator and Brake Booster Pump and bled the system. This all happened in Febuary of 2025. This put everyone at risk because it could have resulted in a total brake system failure. There were no issues or lights before this incident.

2013 Toyota Highlander Limited sunroof drains continue to back up and dump water into the front and rear cabin, causing electrical issues and mold if not addressed immediately. Also the factory-installed roof rack mounting holes allow water to enter the cabin, causing damage to the headliner, which could fall down while driving. Water also collects in the floorboards in both the front and rear and the third row. This water damage causes rust of metal parts on the seats and inside the cabin, which impacts the seat belts and seat hinge points. Toyota refuses to recall models with this issue and lets owners pay out of pocket for repairs while the issue continues to affect the electrical, braking, mold, rust, unprotected metal seat components, and more. This vehicle has been in the shop 4 times for this same issue in 2025 alone.

A persistent smell of fuel occurred while in slow moving traffic and after vehicle was parked after use. Upon close inspection, the fuel injector fuel rail end cap exhibited a slow fuel leak. This component caused a recall for year model highlanders for 2014 production year describing the same type of component failure. The component has faulty end cap weldment that fails, causing the same failure mode being observed in my highlander. This is a fire hazard! Fuel rails should not be failing like this. A replacement fuel rail assembly has been order from Salinas Toyota. The original component can be made available for inspection/testing. I will also take a video of the leak and provide file upon request.

I own a Toyota and have always been a strong supporter of the brand — I truly believe Toyota’s reliability and build quality are unmatched. That’s why I was shocked and disappointed to discover that the paint on the roof of my car, especially near the sunroof, had started peeling. I left for a two-week trip, and when I returned in June 2025, I noticed that the paint had begun to flake and peel severely. The surface felt brittle and dry, and simply touching the area caused more paint to come off. It was clear that the damage had occurred during sun exposure while I was away. I later learned that Toyota had launched a Customer Support Program related to paint issues on white vehicles, but I was completely unaware that it existed or that it had ended in 2024. Had I known, I would have brought the vehicle in sooner. My car only started showing signs of this defect in mid-2025, well after the program had expired. I’m reporting this because I believe the issue is still ongoing and more widespread than Toyota may realize. As a loyal Toyota owner and enthusiast, this experience has been incredibly frustrating and disappointing.

Driver side airbags (curtain and left seat) spontaneously deployed while I was parking the car. I did not hit anything. I was not injured but my safety was put at risk because I likely would have crashed if it had happened while I was driving. I contacted Toyota and they sent an investigator to inspect the car. He found no issues in the data he collected and could not give a reason for the airbags deployment. I received a letter saying they were not going to help in any way. There were no warnings lights or indicators that could have warned me of the airbags deploying prior to the incident.

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.
