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 booster pump will burn out, possibly catch fire and/or blow the fuse and then the braking will loose power assist, and with unit in place....that makes braking almost impossible as it is NOT a typical brake system, all fluid goes through this failed module and without the electronic boost assist, one can not press the pedal hard enough to engage the brakes.
NHTSA complaint #11763765 — an unverified report by a vehicle owner.
Ongoing severe engine surge after coasting while braking lightly during moderate downhill drives on pavement. It happens consistently with different drivers at speeds between 25 to 45 mph. The surge can cause the vehicle to lurch forward enough to move the vehicle forward suddenly, and rapidly to other cars ahead. This is an unpredictable issue, but occurs multiple times daily. Very concerning for everyone at risk in the vehicle. This issue was presented to several Toyota dealers in the San Diego (Carlbad, CA) and Temecula, CA areas during routine servicing during new car regular servicing up to 36k mi. It was documented at those dealers 4 times. They could not reproduce it until the 4th service appt at Temecula, CA Toyota. Toyota has a remedy for previous years' models of Highlander Hybrid, which was a software upgrade to the hybrid braking/engine system. But not the 2023 year. Yet.

When I’m driving with the A/C on when I start to decelerate to a stop at a stop sign or light, my car lurches forward. It feels like I’m going to crash into the car in front of me, but I’m not sure how far it actually moves. It happens more in the summer months (more than once per week) when the A/C is on. In the winter it does happen less often. I purchased the car in 2021 and it has done this for at least the last 3 years if not longer.
NHTSA complaint #11763515 — an unverified report by a vehicle owner.
The contact owns a 2019 Toyota Highlander. The contact stated that while attempting to depress the brake pedal, the brakes failed to operate as intended. The contact stated that after taking the foot off the brake pedal, the brakes started working as intended. The vehicle was drivable. The vehicle was driven to the residence, and the contact researched and became aware that there were several owners who had the same failure. The failure mileage was 69,000.
NHTSA complaint #11762734 — an unverified report by a vehicle owner.
While driving and applying the brakes to come to a complete stop at low speed (approximately 5–15 mph), the vehicle intermittently loses brake responsiveness for a brief moment during the transition from regenerative braking to hydraulic (friction) braking. This causes the vehicle to lurch forward unexpectedly before the brakes fully re-engage. The issue is intermittent and unpredictable, occurring most often when coming to a stop at slow speed, which makes it difficult to anticipate and compensate for. This has happened more than a few times now, most latest, On XXX, this occurred while approaching a stop at traffic light and it felt that the vehicle nearly made contact with the vehicle ahead of me. I brought the vehicle to Elgin Toyota in [XXX] , in 2025 to report this issue. The service department test drove the vehicle but was unable to reproduce the symptom and did not perform any repair. I have since learned that Toyota issued Technical Service Bulletin T-SB-0059-23, "Hybrid Regenerative Brake Transition Feeling Improvement," dated XXX, which describes this exact symptom in 2020–2022 Toyota Highlander and Highlander Hybrid vehicles. I am filing this report because I believe this is a safety-related braking defect, particularly at low-speed stops, that creates a real risk of a rear-end collision.

NHTSA complaint #11761604 — an unverified report by a vehicle owner.
The cars brakes will release and car will lurch forward forcing you to hit the brakes again to avoid colliding with car in front of you. This is a KNOWN problem called "HYBRID REGENERATIVE BRAKE TRANSITION FEELING IMPROVEMENT" PER Toyota's TSB-0059-23. They know of the problem, but do not tell people about it upon bringing car in. My car is starting to do it more now, and they will not cover because it is "beyond 36,000 miles or 3 year manufacturer warranty" This is NOT a minor safety problem. I have had this happen being first car to stop at red light and brake will release and lurch forward almost causing me to go into cross traffic! It has happened multiple times almost making me hit the car in front of me (rear ending the car stopped in front of me). This is not a warranty issue like the weatherstriping on window is bad! THIS IS A SAFETY ISSUE INVOLVING 100,000 OF CARS. DO NOT WAIT for someone to get seriously injured by this or killed because of it (think kid in crosswalk walking and Suv stops, then lurch forward into them!) who is going to sue whom? Also, the injury or death could of been prevented. Now they charge over $350 to fix. This is with 2020-2022 Toyota Highlander Hybrids. Make Toyota know that this is unacceptable and a SAFETY hazard NOT a non injury causing type event. Thank you
NHTSA complaint #11761642 — an unverified report by a vehicle owner.
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.

Incident: [XXX] Conditions: Clear daylight, dry pavement, normal highway conditions Crash/Injuries: Allstate Claim #[XXX]; several people injured At approximately [XXX], I was driving my 2020 Toyota Highlander Hybrid at about 55 mph in the slow/right lane. The vehicle ahead suddenly made a hard stop. I immediately and forcefully applied the brakes for an emergency stop. My front-seat passenger, [XXX], also saw the danger and yelled for me to stop at the same time. Based on our recollection, approximately five seconds elapsed between his warning and the collision. Despite the rapidly closing distance, the Toyota Pre-Collision System (PCS) did not appear to activate. There was no audible warning/beeping, no flashing red warning, and no “BRAKE!” indicator on the dashboard. This was also observed by [XXX] and [XXX], who was seated in the second row and is particularly attentive to warning signals. The vehicle also did not appear to provide any automatic emergency braking or brake-assist intervention. Despite my immediate and forceful braking, the vehicle did not stop in time and collided with the vehicle ahead, causing significant damage and injuries. The forward-facing sensors and windshield were clean and unobstructed. There were no dashboard warning lights or known system malfunction indicators before the crash. I purchased the Toyota Plus service package after completing the required maintenance during the initial coverage period. All scheduled maintenance and inspections were performed on time by certified Toyota technicians. I was repeatedly assured that the vehicle, including the braking system, was operating normally. I request that NHTSA investigate the possible failure of the PCS, forward collision warning, automatic emergency braking/brake assist, and their integration with the braking system.

Coming to a stop or slowing down the vehicle has a spot where it feels like the brakes fail then come back on. Especially if going down a grade. This happens around 15 to 20 mph. Started off a slight moment when you are sure the brakes quit working for just a second. As the vehicle gets older it has brown to be more noticeable.

I was told by oxmoor dealership I had to talk to toyota corporate before I could get my car touched and that I did not need to talk to a lawyer. I called. Prior to the accident, the vehicle had been exhibiting multiple symptoms: an intermittent airbag warning light had illuminated briefly on the dashboard on a few occasions, and the vehicle had begun requiring noticeably longer physical distances to come to a complete stop at traffic signs and lights when not using cruise control. The vehicle was experiencing regular phantom seatbelt warnings—dinging as if a passenger was unbuckled when the seat was completely empty. The phantom seatbelt warnings i didnt think we're a big deal were occurring across multiple seating rows simultaneously in front and back. Directly preceding the crash, while making a turn, the vehicle swerved slightly. When I applied the physical brake pedal, the vehicle did not decelerate normally; instead, it experienced a sudden, abrupt forward acceleration surge into the building. I still haven't gotten my vehicle back or any information on what has been done or when I am getting my car back. I was also charged for an extra day for my rental when I was told to return it on the 16th. I haven't had a rental since then. I keep contacting oxmoor toyota and they said they were waiting on toyota corporate. I haven't had my car for a month. I tried to email. It was returned. My mailbox on my phone has been full of drs and other calls non stop. I texted online on the toyota page for the claim as well. Ive repeatedly asked the toyota dealership what is going on and I get we are waiting on corporate. I called toyota corporate again today and was told they would get back to me. I told the dealership. I am under medical care and in severe pain. Yes my safety was put at risk. Police and fire department were here the night it happened. They said they don't do a police report on private property. There is an insurance claim through state farm.
NHTSA complaint #11756049 — an unverified report by a vehicle owner.
I had the dealer perform the repair described in Toyota Technical Service Bulletin T-SB-0059-23 (Hybrid Regenerative Brake Transition Feeling Improvement), which reprograms the brake actuator control module. Following this repair, the vehicle continues to exhibit the same lurching behavior at the same frequency as before the update. The TSB did not resolve the underlying condition. This is a safety concern because the unpredictable brake transition affects the driver’s ability to judge stopping distance and vehicle behavior in real time, particularly in traffic or on downgrades. The vehicle now has over 36,000 miles, placing it outside Toyota’s Basic Warranty; however, this is a safety issue that should be addressed by a recall. I am aware of numerous other Highlander Hybrid and Sienna Hybrid owners reporting the same defect, including reports that the same TSB reflash failed to resolve the issue for them as well.

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
NHTSA complaint #11755074 — an unverified report by a vehicle owner.
2023 Toyota Highlander Hybrid Regenerative Brake Transition loss of brake pad pressure resulting in acceleration of the vehicle under downhill conditions. Have momentarily experienced the loss of braking frequently during braking when going downhill. This results in the vehicle gaining speed during this 1 or 2 second period before braking returns. In one case it allowed our car to get dangerously close to the vehicle ahead of us but fortunately I was able to push the brakes harder to prevent an accident but did require aggressive braking. Luckily no one was behind us which may have resulted in the person following us braking hard or possible hitting us. This was a known issue for previous year Toyota Highlander models and Toyota issued service bulletin T-SB-0059-23 which is stated to only be for model years 2020 - 2022. So, Toyota dealers say they do not have a fix that applies to the 2023 model. It has been indicated that the dealer is unaware if any action is being taken by Toyota to address this issue in the 2023 and later models. We have multiple people driving this vehicle and this sudden loss of braking power is very concerning. The loss of braking force occurs upon the transition from regenerative braking to standard hydraulic breaking. Below are words from the Toyota Technical Service notice concerning the problem. "Highlander Hybrid vehicles may be sensitive to the momentary transition from regenerative braking to hydraulic braking under certain driving conditions, such as while driving downhill, or turning with light brake pedal application. The brake actuator control module can be updated to improve brake feeling for this condition. Follow the Repair Procedure in this bulletin to address this condition."

I am submitting this complaint regarding a serious braking safety issue with my 2020 Toyota Highlander Hybrid Limited, which currently has approximately 70,000 miles. I brought my vehicle to Victory Toyota of Canton (46352 Michigan Ave, Canton, MI 48188) and reported to Service Manager John Maddison that, at low speeds, the vehicle briefly surges or feels as though it accelerates when I press the brake pedal before it actually begins to slow down. This behavior is alarming and creates the impression that the vehicle is moving forward when I am attempting to stop. This is a serious safety concern that could increase the risk of a crash, particularly in parking lots, stop-and-go traffic, or around pedestrians. The issue has become so concerning that my daughter refuses to drive the vehicle because she no longer feels confident that it will stop properly when she applies the brakes. A driver should never have to question whether a vehicle will respond correctly during normal braking. After researching the problem, I discovered that Toyota has already acknowledged this exact condition by issuing Technical Service Bulletin (TSB) TSB-0059-23. The symptoms described in the TSB closely match the behavior my vehicle is experiencing. I therefore requested that the dealership inspect the vehicle and perform the repair outlined in the bulletin. Instead of addressing what appears to be a known braking-related issue, the dealership informed me that I must first pay a $190 diagnostic fee before they would even determine whether the TSB applies. I believe it is unreasonable to require customers to pay to confirm a condition that Toyota has already documented, particularly when it involves the vehicle's braking system and potential safety risks. I am concerned that other owners experiencing the same braking behavior may delay seeking repairs because of the required diagnostic charge, leaving potentially unsafe vehicles on the road.I respectfully request that NHTSA review this issue.
NHTSA complaint #11752951 — an unverified report by a vehicle owner.
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 not made aware of the failure. The failure mileage was approximately 195,000.

When applying brake, in sporadic and unpredictable circumstances, the vehicle seems to switch from regenerative braking to brake pump braking. During this switch, braking power is lost completely. The vehicle was inspected by the Dealer, they stated no issues found / unable to reproduce. This issue, if unresolved, increases risk of vehicle collision. No warning lights, no messages, no other symptoms of the problem. This issue has been present for ~1.5 years.
