2006 Toyota Highlander Brakes Problems

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. The manufacturer was not made aware of the failure. The failure mileage was approximately 195,000.

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.

The vehicle suffers from an ABS module failure. I've been researching that this is common problem with the Toyota Highlander Hybrid and presents a danger of failing brakes while driving. My brakes partially failed with my [XXX] son in the car. When attempting to stop, I had no hydraulic pressure and luckily was able to get the vehicle stopped after the car had regained some pressure. The vehicle had been running for several minutes, so it wasn't related to a fresh start and the system not having time to pressurize, if that's a thing.

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!

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). Problem 2: When starting the car, the brakes are applied first, and then the car is placed in gear. The car involuntarily and immediately jumps forward or backward and continues to move, even though the brakes are being applied. Having the foot on the brakes has NO EFFECT on the car moving! The car should not move at all when the brakes are being applied. To stop the movement, I must quickly pump the brakes repeatedly. This occurs every time the car is placed into gear after starting the engine, causing it to jump forward or backward and continue moving despite brake application. Both problems are severe safety issues, and could result in injury, death, or property damage.

The ABS Module on the vehicle continually go bad. A newly never used one was purchased 2yrs 4 months ago. A genuine Toyota part ($1300) and it has already gone bad. This is causing safety issues as the brakes make a loud thumping sound when pressed. The car also starts rolling in reverse when turned on if the engine hasn’t started as yet.

Over 2 year ago our 2006 Highlander Hybrid began making a series of noises when depressing the brake pedal when in park and in motion. Dashboard screen are showing Check ABS, Check VSC System, Check Brake System and Brake Malfunction, and Errors. The noise would get louder and last longer and took longer distance to slow or stop. The shop asked for over $3000 that I don't have to fix so I drive it less and less. Please help if possible.

The Brake Actuator on many Toyota Hybdrid and Lexus Hybrid models fails prematurely leading to a unsafe situation with virtually no braking. Toyota extedend the warranty on the item however there are many cars which didn't qualify for the repalcement and are still failing. This should have been a recall rather a warranty extension. This Brake Actuator fails because of a design flaw, it has been since redesigned. The part istself is priced by Toyota at about $2000 in addition to installation labor that can run in thouands depending on the Toyota model.

When braking, apparently when the vehicle transitions from regenerative braking to hydraulic braking, there is a brief total loss of braking force and a noticeable sense of acceleration before the hydraulic brakes begin to grab and slow the vehicle resulting in an unanticipated increase in stopping distance and causing a near collision as my vehicle went several feet past the stop line into an active intersection due to this defect.

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.

Brake Actuator Assembly is a known issue with several Toyota models including my Hylander Hybrid. Toyota tried to address these actuator issues by extending the warranty coverage for the Brake Actuator Assembly on a limited basis, however; there is not an actual recall for this when there obviously should be. Thousands of customers are left with unknowingly driving vehicles that are not safe and for those that have had their brakes fail (and survive) are left with $3,000-$4,500 in repair bills to resolve these issues. In April 2021, I noticed odd purging-like sounds while stopped at stop signs or red lights when the brakes were engaged. This concerned me so, I had our local Toyota dealership check out our highlander but they said there was nothing wrong with the vehicle and we assumed they knew what they were talking about so we went about our business. Unfortunately, some months later while driving hundreds of miles from our home, the Check VSC light, ABS, Brake, and one other dash warning lights came on and the purging sound became much louder. Lucky for us, the brakes still worked enough to stop the vehicle. An official recall would have facilitated our local Toyota Dealer Service Dept in alerting us about these issues before we were put in a dangerous situation. Our Hylander is currently being worked on at our local Toyota Dealership. A guy in the service department is how we found out about the Toyota Customer Support Program that outlines the brake actuator shortcomings/failures. The service dept. manager's exact words were "it's like a recall but it's not an official recall". Here is a video I found on the Toyota Nation website where this gentleman's wife had her brakes fail and hit a car in a parking lot. Thank god she was not injured! https://youtu.be/mn_xs6k8_H4 Ultimately, all Toyota models with these faulty brake components should be recalled!!

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

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. I have researched to find many other people experiencing this same issue with this part going bad AND continuing to quickly go bad even after replacing, and I have been advised the danger of this, for if it goes out while driving, you cannot brake like normal and cause an accident. If a brand new part was making the same buzzing noise when the previous part did not used to make that noise, then something seems very wrong! And this is very much a safety issue if your brakes suddenly stop working like they are supposed to! Please help! I appreciate your time. Thank you!

In the last 4 weeks my 06 Highlander Hybrid has had malfunctions in the brakes and in the power steering. Both issues rendering the car inoperable. The first issue that was to arise was the brake actuator pump. I noticed it was failing when i got in the vehicle to move it out of the driveway and noticed after i put the car in gear that their was no power brake assist. When the car was shifted into drive the car began rolling even while i was pushing hard on the brakes. Luckily the brake assist resumed and i did not run into anything but the car unintentionally moved about 5 feet. I mentioned this to my wife, and she said while driving home one day the car made a high pitched buzz. She was close to home, so she made it home and parked the car and forgot about the noise. After the car was turned back on again no noise was made and no CEL or warnings were displayed. The actuator was replaced, and the car operated fine for about one week and probably 40 miles of driving. I want to mention I had noted a odd feeling in the brakes for years leading up the the failure. The brake pedal would continue to the floor while trying to maintain constant pressure on the brakes. I believe this is due to the actuator losing pressure, but it would cause an uneasy sensation of failing brakes, but no CEL's were ever triggered. The new actuator fixed this. After fixing the car we drove it on a few trips. Yesterday 8/24/21 my wife went to drive the car, and it wouldn't start. She tried about 10 times and it wouldn't turn on. I put a battery charger on the car and the battery looked okay. I tried to start it a few time probably 5 and finally got the READY light, so the car was ready to go, but all of a sudden the car would shut off and the READY light would go out and the P/S light would come on. This light is triggered when something is wrong with the power steering system, and the computer will disable the vehicle. The car immobile now. These are worth recalling.

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. The same service center has checked and diagnosed this car multiple times - so I am surprised that they did not find the ABS actuator noise a problem on earlier occasions. I have been reading about this on this forum and Toyotanation and this seems to be a consistent issue with the older Toyota hybrid highlanders and other hybrids as well - with the same diagnosis and approximately the same price quoted by the service centers. I have not currently fixed this issue since I cannot afford this price. It also seems that I will be paying for manufacturer's or service center's negligence since this actuator seemed to be faulty all along and I was not warned about this.

THE BRAKE ACTUATOR IS FAILING AND IS MAKING LOUD NOISES. THE CAR DOES NOT BRAKE NORMALLY. I HAVE REPORTED BRAKING PROBLEMS SINCE I BOUGHT THE VEHICLE IN 2007. WHEN IT HITS A BUMP IT ACCELERATES AND I MUST STAND ON THE BRAKES SO I DO NOT HIT SOMEONE. IT LURCHES FORWARD WHEN IT HITS A POTHOLE OR SOME KIND OF OBSTRUCTION IN THE ROAD. WHEN I WORKED DOWN NEAR THE BUS STATION I WOULD HIT THE AREAS IN THE ROAD WHERE THE BUSES CREATED BUMPS IN THE ROADWAY AND IT WOULD LURCH FORWARD. I REPORTED THIS NUMEROUS TIMES AT NORTH BAKERSFIELD TOYOTA. I RECENTLY WENT IN TO REPORT THE NOISE I WAS HEARING AND THEY FINALLY FIGURED OUT THAT THE BRAKE ACTUATOR IS FAILING. I WAS TOLD THAT IT WAS NOT A HAZARD BUT THEY COULD NOT TELL ME WHEN IT WILL TOTALLY FAIL. I BELIEVE IT IS A SAFETY HAZARD AND THERE HAS BEEN A PROBLEM FROM DAY ONE
