2006 Toyota Highlander: ABS light or ABS activating

Filed Oct 7, 2026 · Brakes · CA

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

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 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.

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!!
