Toyota Highlander abs comes on

Subject: Sudden Unintended Braking and Loss of Vehicle Control – 2008 Toyota Highlander V6 AWD I am reporting a serious and potentially life-threatening incident involving my 2008 Toyota Highlander V6 AWD. Shortly before this incident, I had all four tires replaced at Les Schwab. While driving approximately at highway speeds, with my foot on the accelerator and absolutely no pressure on the brake pedal, I suddenly heard a knocking sound and felt the vehicle jerking violently. It felt similar to ABS activation, although I do not know what system was responsible. I stopped and inspected everything finding nothing wrong so proceeded to drive the car back home. The vehicle then suddenly and forcefully applied the brakes without any input from me. The rear wheels appeared to lock, causing the tires to skid. The back end of the vehicle fishtailed and began attempting to spin around. I struggled to maintain control. There were three children riding in the vehicle with me. All four occupants were placed in immediate danger. After stopping, I shifted into Park and then back into Drive. The brakes released, and the vehicle began moving normally again. However, I subsequently noticed a continuous metallic grinding noise. No ABS, traction control, or other warning lights illuminated. I am requesting an investigation into the cause of this sudden unintended braking, rear-wheel lockup, and loss of vehicle control. This incident could easily have resulted in a fatal collision. Three children were passengers in the vehicle when it unexpectedly applied its own brakes at approximately 45 mph.

Multiple warning lights appeared on the dash board including ABS, also check VSC system in the dialogue window. Code C1391 (Abnormal leak in accumulator) appeared in a diagnostic scan. After some internet research, it appears this a common problem with the 2006 Toyota Highlander and is a very costly repair $2000-$4000. The leaky accumulator creates an unsafe driving condition as the ABS and VSC system are disabled due to the leak. Due to the high number of failures for these vehicles, I feel that Toyota should take responsibility and warranty this part and repair. Thank you

The ABS/Brake Actuator is going out. There is a stuttering as I'm coming to a stop, but when I brake from normal speeds to slow down, there is no stutter/vibration. Only when I'm going very slow and about to stop the car is when I feel a vibration/stutter in the vehicle. When pressing the brakes all the way down, there is a weird chirping/clicking noise that comes from under the hood towards the passenger side of the car. I do not have and did not get any warning lights about this, even still I don't have any. I have taken it to 2 mechanic shops now and they both have diagnosed the brake/ABS actuator failing.

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 risk we could have crashed it if I wasn't an actual driver by trade I wouldn't have known how to react in other families could be harmed in this. It's worth looking into I did not need to make her police report because I veered off into a field that saved my family's life. As of now I'm hoping to open a recall campaign and just have that part replaced I could have a car that could drive another 100,000 miles and give and keepToyota good name

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.

Four days after I took delivery of this used vehicle (April 25, 2026), multiple warning lights appeared at once: BRAKE, ABS, PARK, Check Engine, Blind Spot Monitor Unavailable, and RCTA OFF. An independent Toyota dealership diagnosed the vehicle April 27-28, 2026 (approx. 109,000 miles) and found (1) water leaking into the rear hybrid battery area through a sunroof drain "installed incorrectly," causing a Brake System Control Module low-voltage code, starting issues, a headlight only partially functioning on one side, possible air in the brake system, and a musty HVAC odor; and (2) blind spot monitor fault code C1AC2 (Slave Module Horizontal Axis Misalignment) - the blind spot and rear cross-traffic monitoring systems do not function reliably. At a second visit on May 4, 2026, recalibration was unsuccessful; per Toyota procedure the only remaining option is replacing the right-rear blind spot sensor. The technician wrote the cause is a mystery, "whether it be body damage related or electrical short." Toyota service records show the same C1AC2 code was documented during the selling dealer's own pre-sale inspection, and that in December 2024 another Toyota dealership pulled the rear bumper and found the RR blind spot sensor bracket bent, causing incorrect readings - a recurring safety defect that prior calibrations and repairs have not resolved. Separately, federal safety recall 23V865 (occupant classification sensors; the passenger airbag may not deploy as designed) was open and incomplete when I purchased the vehicle and remains incomplete, and Toyota service campaign 25TD01 (rear traction motor cable corrosion) is also outstanding. The defect has been reproduced and confirmed by two Toyota dealerships, reported to the selling dealer in writing, and reported to Toyota's customer-care center. The vehicle is available for inspection upon request. No crash, fire, or injury.

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.

My 2006 Toyota Highlander Hybrid Limited has an ABS fault that has caused my vehicle to undergo several maintenance issues and poses a serious safety hazard. My vehicle has less than 150,000, and over the course of the last year, my ABS light, my emergency brake light, my TSC light, and my tire pressure sensor light have all come on and refuse to go away. Additionally, the maintenance light, along with a "CHECK VSC SYSTEM" message has been on my dash for months and will not reset. My ABS has been making an intermittent buzzing sound that cycles every ten seconds when my car is on. That has been going one since shortly before the lights. When the lights came on, I noticed a serious change in my braking. The pedal would become spongy one moment and rock solid the next, or my car would brake intensely with the lightest pressure or require my foot basically to the floor to stop it. This has caused a serious issue for the safety of myself and my family. After using and OBDII scanner with ABS capabilities, the codes I received point to the ABS assembly failing to retain pressure, hence the persistent cycling to compensate for it loosing pressure. This was confirmed after the battery voltage/connection, relays, fuses, and speed sensors had all been tested. After doing further research, several other owners of similar configurations to mine share the same issue. My dashboard even makes an incredibly distracting ringing noise that can only be stopped by removing all the fuses and relays to the ABS entirely. This has not been caused as a lack of proper maintenance as this vehicle has only been in my possession for the past 3 years, of which before it came from the Toyota dealership. The dealership wants over $3,000 to fix the issue, and the part alone is $1,850 since the part has been discontinued. This fix costs more than the car is worth given its age and mileage. During any inclement weather, or in traffic, the car is unpredictable in how hard it might brake.
