NHTSA crash tests

The agency crash-tested this model year itself. These are its own photographs and star ratings.

These stars come from the pre-2011 crash test programme. NHTSA rebuilt the programme for the 2011 model year and states that ratings either side of that change are not comparable — so do not read these against a 2011-or-newer car's stars.

NHTSA investigations into the 2010 Toyota Highlander

An investigation is the step before a recall: the agency has seen enough complaints to look into a pattern itself. An open one means it thinks something may be wrong and nothing has been fixed yet.

EA18006 Opened 16 Nov 2018 Closed 2 Apr 2024 STEERING:COLUMN

Steering Column Separation

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,...

Recalls on the 2010 Toyota Highlander

A complaint is one owner's allegation. A recall is the point at which the manufacturer or a regulator agreed the defect is real and dangerous enough to fix for free — however old the car is.

Canada — Transport Canada

Canada runs its own recall programme, and its campaigns do not always mirror the American ones.

Recall 2021723 55,683 units in Canada

Electrical

Issue: This recall is for certain block heater kits installed on certain vehicles or sold as accessories at Toyota or Lexus dealerships. On certain vehicles, the engine block heater cable may not have enough heat protection and could be damaged by high temperatures. If this happens, the cable could short circuit while plugged in, and cause the wiring to overheat or melt. Note: This recall only affects the following block heater/cord part numbers: C014003034 PK5A408J09 PU14000904 C014003151 PK5A408J13 PU14000905 C014000885 PK5A489J11 PU14000907 C014000888 PK5A489J22 PU14000909 C014000907 PK5A410H00 PU14000911 C014100904 PU14000900 PU14000913 C014100907 PU14000901 PU14003571 C014100911 PU14000902 PK5A489J14 PK5A408J05 PU14000903 Safety Risk: Engine block heater wiring that overheats or melts could create the risk of a fire. Corrective Actions: Toyota recommends that you should stop using the engine block heater immediately. Toyota will notify owners by mail and instruct you to take your vehicle to a dealer to disable the engine block heater. For some vehicles, the corrective actions for this recall are under development. For others, a new engine block heater cannot be installed, and the owner will receive a refund of the purchase price of the engine block heater.

Recall 2015493 315,091 units in Canada

Electrical

On certain vehicles, inconsistent application of grease during the manufacturing process could cause the driver's side power window master switch to stick or become inoperative due to electrical contact point wear. This could cause debris to accumulate between the contact points, potentially resulting in an electrical short circuit. If a short circuit occurs, the switch assembly may overheat, produce smoke, melt and/or potentially lead to a fire causing injury and/or property damage. Correction: Dealers will inspect the driver's power window master switch and apply a specialized grease that inhibits heat build-up, or replace the power window master switch circuit board, as necessary. Note: This is an expansion of recall 2012-338.

Recall 2014124 344,870 units in Canada

Airbag

On certain vehicles, electrical circuitry in the steering wheel assembly may become damaged. As a result, the driver's airbag may not function as intended, causing the instrument panel airbag warning lamp to illuminate. Failure of the driver's airbag to deploy during a crash (where deployment is warranted) could increase the risk of injury to the seat occupant. Correction: Dealers will replace the spiral cable assembly.

Recall 2010124 46,923 units in Canada

Accessories

On certain vehicles, if the Toyota optional accessory "tray-type" floor mat is not secured by the retaining hooks, or if it is placed on top of an existing floor mat, the "tray-type" floor mat could move forward and interfere with the accelerator pedal. This could result in a crash causing property damage, personal injury or death. Correction: The manufacturer will notify owners to remove the "tray-type" floor mat and provide instructions on how to obtain a reimbursement.

Recall 2010012 273,050 units in Canada

Other

On certain vehicles, accelerator pedal movement may become rough, slow to return, or the pedal may stick in a depressed position. This could result in a loss of throttle control and a vehicle crash, causing property damage, personal injury or death. Correction: Dealers will install a steel reinforcement bar to the accelerator pedal assembly. With this reinforcement in place, the excess friction that can cause the pedal to stick is eliminated.

Recall 2009290 437,445 units in Canada

Other

On certain vehicles, the accelerator pedal may become stuck in the wide open position due to an unsecured or incompatible driver's floor mat. A stuck open accelerator pedal may result in very high vehicle speeds and make it difficult to stop the vehicle, which could cause a crash, serious injury or death. Correction: Dealers will reconfigure the shape of the accelerator pedal. Certain models will also have the shape of the floor underneath the accelerator pedal modified and/or a brake override system installed.

St. Louis, MO Crash

SERVICE BRAKES

When traveling a slow speeds (less than 15 mph) and needing to stop, the brakes are pressed but do not respond. This has happened on several occasions and has caused two separate accidents where the Highlander has failed to stop and it runs into the car in front. After the first accident, we looked for recalls (2015) and there were none for any model Toyota for brakes or brake systems. We brought the car in to the mechanic and had all the brakes and pads replaced, although they said nothing was wrong with the shoes nor pads. Now, years later, another accident in the exact same way. Luckily, due to the slow speed, no one was hurt but this is definitely a problem with the car. There have never been any warning lights, or sounds that would indicate an issue.

When we received this bulletin, we asked our Toyota Dealer Service Department (Stevenson Toyota East, Denver, CO) to address this issue multiple times when bringing in our vehicle for service in 2019 and 2020 and were told repeatedly they would not fix this issue since the ABS light was not on. Now that this bulletin is expired the ABS light is on. We took our Highlander to the Toyota Dealership in Melbourne, Florida and were told that this repair will now cost us $2473.89. Our 2010 Highlander is barely worth that, and now we have to repair this on our own even though Toyota knew the brake actuator assembly and brake booster pump would eventually fail at some point in time. Despite this, Toyota refused to resolve this issue when we asked (more than once) right after receiving the service bulletin in 2019 and as a result is causing a safety issue for our college aged son who drives this car, and all other drivers on the road should the ABS system fail. The attached estimate states the ABS service light has not come back on but this is not true and my son is having issues with the brakes.

Affected by the faulty Brake Actuator & Accumulator on 2010 Toyota Highlander Hybrid. Brake malfunction and ABS disabled lights popped up on my Multi-Information Display. This issue disables ABS & VSC systems, which therefore makes this a safety hazard. Upon doing research, I have concluded that many complaints about this specific "Brake actuator & accumulator" have been issued. In the past, Toyota has provided a "Customer Support Program" which expired in 2020, but this does not help current owners like myself, who are stuck with this problem.

On approx. October 19, 2023 my vehicle started showing 4 error messages on the display: Brake Malfunction, Check ABS, Check VSC System, and Check Brake System. At the same time, these 5 warning lamps became illuminated: Brake System Warning Light and Warning Buzzer (Red), Brake System Warning Light (Yellow), Master Warning Light (Yellow), ABS Warning Light (Yellow), and SLIP Indicator (Yellow). A car repair technician obtained the following error codes from the vehicle in a diagnosis: C1391 (Abnormal Leak in Accumulator). I was informed that the VSC (vehicle stability control) safety feature of the vehicle is disabled while the error codes and messages are present. Toyota previously issued a customer support bulletin (No. POL19-06) on June 6, 2019, titled "Customer Support Program ZKC: Certain 2008-2010 Model Year Highlander Hybrid Vehicles Coverage for Brake Actuator Assembly and Brake Booster Pump Assembly". In the bulletin, Toyota acknowledged that its 2008-2010 Highlander Hybrid models had "certain internal malfunctions of the Brake Actuator Assembly". Affected error codes include C1391 and C1253, among others. Affected warning lamps consists of all 5 of the warning lamps that were illuminated in my vehicle. Affected parts include 04008-26448 (Actuator Assy, Brake w/ Fluid) and 04008-51148 (Pump Kit, Brake Booster w/ Accumulator). Instead of issuing a recall for this hazardous defect, Toyota opted to offer "Customer Support Program ZKC". The malfunction that manifested my vehicle is not eligible for this program. Toyota should issue a proper recall to address this safety hazard.

SERVICE BRAKES

The brake actuator (4405048320) and brake booster pump (4707048020) malfunctioned. The ABS warning came on the display, as well as a warning saying “Brake Malfunction: pull over car immediately.” The traction control light, ABS light, warning light, and parking brake light also came on. The computer code was C1391. This controls the brakes and anti-lock brake system. This is a serious and known safety issue. It is well-documented online, and in 2019 Toyota acknowledged this widespread issue with a Customer Support Program ZKC. However, this program only applied for a limited time, and since then more vehicles have had this same issue with faulty parts. Even vehicles under 150,000 miles no longer qualify for free replacement despite this being a known and widespread issue.

My issue is not that I got a brake warning light (see attached image). My issue is that Toyota knows that this is an issue and will only fix it if you experience the issue before 12/30/2020 or at less than 150,000 miles. It is irresponsible of Toyota to know this is an issue, especially regarding the vehicle brakes (see screenshots of the letter from Toyota).

EXTERIOR LIGHTING:HEADLIGHTS:BULBS

I purchase The H4 LED’s from headlightexperts.com February 2022. There is a design flaw with their H4.bulb. The low beam have LED’s on both sides of the light bulb, however the halogen bulb has a shield so that light will only come out of one side of the bulb. The result of leds on both sides of the low beam is light hits the high beam reflector from the back side of the low beam led bulb, and blinds oncoming vehicles. When I contacted customer service via email, they kept saying I have the bulb at the wrong angle, and sent me links to 2videos for proper installation. I keep adjusting the bulb, at first with 45degree turns but then even less- still the light from the back side of the low beam bleeds onto the high beam reflector and blinds oncoming vehicles due to this design flaw. When I called the companies Phone number [XXX] it links to their sales department only. I attempted to explain the issue to their salesman who salesman who proceeded to dismiss the concern as my fault for not installing it correctly. There is no way to install this product correctly due to the fact it has low beam leds hitting a high beam reflector. When I pointed out the safety issue this product creates, I was told to look elsewhere for “some unicorn bulb that doesn’t exist.” He was rude, Hostile and argumentative.. When I attempted to explain the design flaw issue again, he selected would talk over me saying “bla bla bla bla bla” when ever I spoke like a 4yr old. In short there was ZERO concern for public safe their product puts at risk. I have included photos of both sides of their product showing high and low beam leds on both side of the bulb, as well as photos of a standard halogen bulb with the metal shield to prevent any spillage of low beam light onto a high beam reflector- INFORMATION Redacted PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6).
