2006 Toyota Highlander

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 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.

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. 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.

Toyota’s part number 44050-48190 brake actuator assembly failed, as it has in other models and is very commonly doing in the Highlander model. It is triggering other warning lights issues in the vehicle. Vehicle safety is at risk. Many others have reported the same issue.

I was on the interstate driving about 72 mph when the car just shut off all the dash lights came on and the dash it said check hybrid system I had no brakes or steering I got it off the road turned it off and back on again it started up and I drove it home but the dash still displayed check hybrid system , a week later I get in it to go to work and there’s an alarm that won’t cut off and the abs , traction control and brake light and warning light and tire pressure light are all on and the brakes are hard and there’s a weird noise coming from somewhere when u push on the brake and it says check VSC system on the dash now

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!

The driver's side sun visor does not stay up against the roof of the car and falls down obstructing the driver's view. It will not stay up and falls down immediately when pushed up against the roof. We have resorted to tying the visor up but then are unable to use the sun visor while driving.

Car is lunging forward while braking.I just had to put a new abs module and pump on the vehicle which was very expensive.Since I know there was a recall but I was not notified.Is there a way to get toyota to pay for the new pump and module ?

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 past couple months the Brakes have been acting up. Changed brakes and rotors to only find out that my brake pump or actuator are faulty and a known issue for highlanders yet my vehicle had no recalls

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.

Power brakes stopped working while driving due to bad brake actuator. Vehicle shut down while driving due to power train system.

I can see many complaints similar to mine on line since the car was built in 2006. Driving on a 7hr trip when engine light came on and car overheated. We had to pull over on a busy highway and wait for car to cool down and light to go off. It was scary since I had my child in the car and traffic was moving at 60 mph. The next day I had the Toyota dealer charge me $160.00 to tell me coolant and oil were leaking from the head gasket and the bolt corroded and listed out causing a sealing issue. We just had the car in their shop doing thousands of dollars of maintenance and had a full inspection done in preparation for this trip. We also had fluid leaks from the engine twice before at 65819 miles and again at 84458 miles. No mention of this issue was ever brought up by dealer. I have full records and always did maint as suggested. so now the dealer says it will need a used engine at a cost of $9,000+. I am now without a car. This car should have been recalled and repaired, now it is totaled it. Thank goodness we were not injured or hit by another car on the interstate. sorry unable to send a copy of repair estimate done at Daytona Toyota 386-255-7475
