2010 TOYOTA HIGHLANDER Complaints

My car all of a sudden went into limp mode while driving on the 91 freeway with my kids in the car on may 21 2026. It had master warning ?? light and check engine light and a circle warning light that is the braking system also it said on the screen check hybrid system stop the vehicle in a safe place immediately and contact a dealer. It smelled like smoke as I was trying to get out of traffic and drive it to the shoulder.I towed the car to the Toyota dealer in Orange and was told it's the inverter and its fried and needs to be replaced.

When applying the brake slowly all of a sudden the car went full acceleration and crashed 500ft away at high speed. The car is crashed but available for inspection for a short period of time until the insurance company takes full posession. There are not open recalls. The only lights on the dash were for TPMS sensor.

The contact owns a 2010 Toyota Highlander. The contact stated that the gear shifter had been stuck on several occasions. The vehicle was taken to the dealer, where the fuses were replaced on several occasions; however, the failure persisted. The vehicle was taken back to the dealer, where it was diagnosed and determined that the rearview mirror wiring had failed. The vehicle was repaired. The contact related the failure to an unknown recall. The manufacturer was not notified of the failure. The failure mileage was unknown.

Headlamps become cloudy and burn out new, expensive bulbs in months. Internet search says Toyota is aware of problem, but prior to my search my dealership wanted to charge me hundreds of dollars to 'evaluate electrical system'

We received this from Toyota. Customer Support Program Bulletin Date: Page: POL19-06 6/6/2019 1 of 3 REVISED 8/28/19 CUSTOMER SUPPORT PROGRAM BULLETIN (ZKC): REPAIR COVERAGE FOR BRAKE ACTUATOR ASSEMBLY AND BRAKE BOOSTER PUMP ASSEMBLY ON CERTAIN 2008-2010 MY HIGHLANDER HYBRID VEHICLE. 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.

The engine failed and locked up. Maintenance is completed every 3-4 months on schedule. There was no oil or water. Car was towed to a mechanic.

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.

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.
