Selected complaints filed with NHTSA by 2006 Toyota Highlander owners, lightly cleaned up (personal details are redacted by NHTSA).
The contact owns a 2006 Toyota Highlander. The contact stated that while driving approximately 60 MPH, the vehicle failed to decelerate while the brake pedal was depressed. The contact stated that excessive pressure was needed on the brake pedal to stop the vehicle. The ABS and ESC warning lights were illuminated. In addition, there was an abnormal sound coming from underneath the vehicle. The vehicle was towed to a local independent mechanic, where it was diagnosed and determined that the ABS unit needed to be replaced. The vehicle was towed to another independent mechanic for a second opinion, and it was confirmed that the ABS unit needed to be replaced. The vehicle was taken to a local dealer, where it was diagnosed and determined that the brake actuator needed to be upgraded. The vehicle was diagnosed, and parts were ordered for the repair. …

The manufacturer was informed of the failure but offered no assistance. The failure mileage was approximately 175,000.
I was driving the car then as I hit the brakes it felt like they were not engaging until I applied more pressure. Then as I was almost home the abs and traction control lights came on. Took it to a specialist and they said that the abs module would have to be replaced. There are tons of people apparently with my same year and model with the same concern
The dashboard on my Highlander Hybrid 2006 (AWD) had all its check lights on suddenly. I was not driving then. The car was in my parking lot for a few hours before which it had no signs on. The warning message said: Vehicle Stability Control (VSC). I took it to my nearest Toyota service center for diagnosing the issue. They reported that the ABS systems have started to fail. Specifically, the ABS actuator is losing pressure and should be replaced. They quoted a price of $2700 approx. which includes about $2000 for parts. Turns out that this same part had been replaced in 2016 during a recall - but they cannot attend to this again without charging the customer. What I was never told about was that a whirring sound - which has always been an issue with this car - was always from the ABS actuator. …
ABS Control Module. Yes could be made available for review. A few years ago, a diagnostic showed the ABS Control Module as bad (it started buzzing is what made us get it checked). Toyota replaced it, but there was still buzzing after the service, from a NEW part!? I strongly expressed this to Toyota since it still seemed like an issue to me, but they told me nothing could be done unless the computer said it was bad or if there was a recall. The buzzing continued to get worse and does it almost all the time now, and finally the ABS light came on, sometimes it will make an alert noise, and the vehicle will not brake properly (with the brake pedal feeling very firm), so apparently now that the ABS light is on, a diagnostic showed it bad again. …
Two problems being reported are severe safety issues, and could result in injury, death, and/or property damage. Problem 1: While driving, the brake pedal suddenly went all the way to the floor, and the car would not stop. To avoid hitting the car in front at a stop sign, I had to turn the wheel, resulting in running through the stop sign and onto the grass and shoulder before the car finally stopped. Multiple dashboard warning lights appeared. After stopping, the brakes momentarily returned but failed again within 2-3 minutes. A loud, high-pitched, piercing whistle sound began, indicating a complete loss of brakes. The car had to be towed 200 miles back home. It is not safe to drive the car without functioning brakes. The OBD scan codes are: C1256 (accumulator low pressure), C1391 (abnormal leak of accumulator pressure), and C1256 (accumulator low pressure). …
ABS actuator/accumulator issue on 2006 Toyota Highlander hybrid limited. Internal component failure there are recalls on others but not this particular year. Was driving along hit the brakes and got hard pedal. Yes there were other indicator lights on including the VSC system and traction control I came to an intersection and I couldn't stop I couldn't even kind of stop it was all hard pedal were before it was normal as if there wasn't an issue. I've done a lot of research and I've seen a lot of forums and people are complaining that Toyota isn't backing this problem my 2006 Toyota is in perfect condition not a single problem except for this break issue and if you take it to Toyota the park cost $2,200 in about roughly over $5,000 to fix it well who wants to put that kind of money into a car of that year the problem is it's just a shame and a safety deal that it put my family's life at …
The Antilock Braking Actuator has failed. This seems to be a known issue and was already recalled on the Toyota Camry. Toyota sells the part for $1500 locally and labor will be added to that as well - which will put the cost of replacing this critical part almost above the current value of the vehicle. This is a safety issue if I lose braking capability. It has not yet catastrophically failed, but is making a buzzing sound which is the indication of this unit losing brake fluid pressure and trying to keep the brake booster pump running to restore the pressure. …
The brakes on my 06 Highlander hybrid AWD have been finicky at best since I've owned the vehicle. The car lunges forward when braking, all the way until a complete stop. While driving at around 55 MPH a medium sized dog ran out into the road. I braked hard but the brakes just lunging and trying to stop. At one point feels like it's not braking anymore and just hope to veer out of the way. This can be fatal not only to the driver but to others driving as well. The fact that people are still having this issue, and Toyota hasn't come up with a proper long term solution speaks to how much Toyota cares about its customer bases' safety. It is honestly disgusting that people have had accidents and may have fatal and Toyota continues to not care. Please urge Toyota to look into this further and attempt to fix this permanently!
My electric brake computer thu a code C1256 & C1391, ABS Brake Actuator Failure. Not regular maintenance item. No code ever thrown til this time. Major people killer when it fails. My experience was during a rain storm, lost all brakes for maybe 1-2 seconds. Felt like you were on ice. No control, No ABS. Then code and lights on dash lit up. I limped home worried I had no brakes or some brakes. Scared me and my family completely. Now car sits in driveway afraid to drive. I went to dealer, they read the codes and found 2 codes present. C1256 and C1391, ABS Brake Actuator FAILURE, needs to be replaced for SAFE Operation of car. Why isn't this Brake Actuator under warranty? Excessive mileage? How would you know it was bad if you NEVER got the "CODE" as per Toyota Corporation.
