2006 Toyota Highlander Brakes Problems

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.

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

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.

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!

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 ?

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.

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.

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

The contact owns a 2006 Toyota Highlander. The contact stated while driving at various speeds, the brake pedal had to be pumped several times to stop the vehicle. The contact stated that the ABS warning light and several other unknown warning lights were illuminated. The vehicle was not diagnosed nor repaired. The manufacturer was informed of the failure but offered no assistance. The failure mileage was approximately 175,000.

3 accidents all rear end due to brakes ( brake pump/brake actuator failure) not safe.

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!

MY ABS, VSC, (I), AND EMERGENCY BRAKE DASH LIGHTS ARE ON CONTINUOUSLY. IT IS VERY HARD TO STOP THE CAR AS IT FEELS LIKE THE BRAKE ISN'T ENGAGING. WHEN IT DOES ENGAGE YOU ARE JERKED FORWARD.

THE VSC LIGHT, ABS LIGHT AND NOW THE CHECK ENGINE LIGHT IS ON. THE CODE COMES BACK TO C1391 WHICH IS THE BRAKE ACTUATOR. IT IS A KNOWN PROBLEM WITH TOYOTA THAT OCCURS @118,000 MILES. I WAS TOLD IT WAS GOING TO COST $4,000, BUT THEY FINALLY ONLY MADE ME PAY FOR THE LABOR AND TAX. HOWEVER, IT HAS NOW BEEN 30,000 MILES LATER AND THAT PART HAS FAILED AGAIN. I CAN'T AFFORD $2500-$4000 TO FIX A PART THAT ONLY LASTS 30,000 MILES. I HAVE SEEN THIS COMPLAINT OVER AND OVER. CAN WE GET SOME HELP??

TL* THE CONTACT OWNS A 2006 TOYOTA HIGHLANDER. THE CONTACT STATED WHILE DRIVING 25 MPH DOWN A HILL, WHILE DEPRESSING THE BRAKE PEDAL, THE BRAKE PEDAL WENT TO THE FLOOR AND THE VEHICLE HESITATED AND STARTED MAKING AN ABNORMAL SOUND. THE CONTACT STATED THAT THERE WAS NO WARNING LIGHT ILLUMINATED. THE CONTACT REGAINED CONTROL AND STOPPED THE VEHICLE. THE VEHICLE WAS TAKEN TO DCH WAPPINGERS FALLS TOYOTA (1349 U.S. 9, WAPPINGERS FALLS, NY 12590, (845) 288-0892) WHERE IT WAS DIAGNOSED WITH NEEDING THE BRAKE ACTUATOR TO BE REPLACED. THE VEHICLE WAS NOT REPAIRED. THE MANUFACTURER WAS INFORMED OF THE FAILURE. THE FAILURE MILEAGE WAS APPROXIMATELY 191,000.

LOUD CONTINUOUS BEEP BEGAN IN CAR WITH NO INDICATION AS TO WHAT IT WAS. WAS DRIVING AT 40 MPH, LET OFF GAS TO GET READY FOR TURN, HIT BRAKES AND THERE WEREN'T ANY. WAS ABLE TO SAFELY MERGE BACK INTO TRAFFIC AND DECELERATE ENOUGH TO TURN ONTO THE NEXT STREET. DIAGNOSED AS FAILED BRAKE ACTUATOR ASSEMBLY.
