The brake accumulator/actuator is a defective part and Toyota has refused to honor the repair. They manipulated owners by having a warrenty support program with end dates, instead of having a recall on it. Which is why when I researched before I bought, is not listed on car fax. The warranty support was before I purchased vehicle and previously it was either ignored or missed between owners. They have had many of these and get away with it. Right now there is a class action filed in Ohio over this same issue with other cars. It is a $3000 dollar part and not a knob on radio. It is a safety issue due to it being part of the braking system. I've seen where the support program said miles didn't matter but when talking to Toyota they say 114,000 miles. The car is a 2006, yeah that's reasonable, even for 2017/18 letter. While driving the vsc alarm system comes on and the braking becomes difficult. The pump has always made a sound but was told by dealer it was the security alarm system making the noise. It happened in 2019 also, the alarm, but repair shop said it was calipers, so paid $800 to have them replaced with pads. Its always made noise but the alarm system started back up again last month. Now with research on my own, I know exactly what it is but Toyota said they sent letter to previous owner and sorry about my luck! this has rendered this vehicle worth $5500, worthless. Cant trade in a vehicle like this and lost my income from delivery with it. I have checked off everything that would apply if it was a recall but since the support program has an end date to get out of Toyota ever being responsible for their defective part, they push it off on owners. I'm just lucky, I have a cdl and good driver and have not had an accident with it. I filed a complaint with Toyota and they just swiped me away as another poor sucker that didn't figure it out before I purchased.

The brake actuator assembly has gone out at 135000 miles. It interfers with braking. The brakes lock up frequently and car will almost hop to a halt. It is quite concerning and scary when it occurs.

Once after parking and then twice while driving on a highway, the check hybrid system light, the vsc light, the check engine light, and the caution light all illuminated and the vehicle lost all power including steering assistance. Each time requiring multiple key turns to restart the vehicle into limp home mode. This vehicle has been repaired once before for a similar issue which occurred while driving up a hill in moderate traffic. The tank is full of fuel, the tires are less than a year old, and the vehicle undergoes regular maintenance(which includes a new battery as the one bought from Toyota had a few dead cells after only a year or two). I've read multiple complaints about this online while searching for the underlying issue and there seems to be a related recall that doesn't include my VIN.

Ongoing issue with generation 1 Highlander hybrids and prius from same date ranges. A warranty adjustment has already been issued and ended. The ABS brake accumulator gets an internal leak code C1391. Reduced braking, ESC, brake and other lights come on. Many of those repaired under warranty are already failing a second time. Vehicle is dangerous to drive since it can be driving perfectly and fail while in motion causing dangerous braking conditions.

Driving vehicle when warning lights for ABS and skid control came on. Check vsc system in dash. When brake is applied right front tire locks and causes vehicle to spin. Slow speed is the only reason for no accident. Took vehicle to dealer and was told "brake accuator " electronics had failed and needed to be replaced for $3800. Research shows this is an issue on the Highlander, the Lexus and the Camry so why have the Highlanders not been included in the recall?

Complaint: 2006 base Highlander, fwd, 4 cylinders. Brake system (vsc, trac off, ABS & brake) and TPMS lights on, disabling safety features. 1)TPMS flashing light. Issue may have been in-process since day 1. it regularly came on, reset by dealers and eventually showed us how to reset ourselves. 2)brake system lights. All (4) came on, diagnosed as left rear wheel sensor. Dealer quoted cost: $1000. Replacement didn't work, wound up replacing wheel hub assembly pigtail. Lasted two (2) weeks, re-diagnosed as ABS pump/control module assembly. Dealer quoted cost: $2500. While this itself is ridiculous, the repair costs would exceed 1/8th (13%) the cost of the vehicle new! now, in 2014, it's approximately (50%) of the current vehicles value. This issue has recently resulted in screeching to a halt in dangerous traffic. It essentially negates the star safety system features, for various environmental and driving conditions. This issue cannot be ignored any longer, since it's the topic on numerous web site forums and inquiries and even salvaged used parts are being sold by many sites for this problem. Recompense: Remuneration of expenses to date and future repairs to correct this problem is requested. Review of tsb and/or investigation into recall campaign to fix all affected vehicles.
