2006 Toyota Highlander — Known Issues & Recalls

Your ABS system is failing to maintain brake pressure, causing your brake pedal to feel unpredictable—sometimes spongy, sometimes too firm, and sometimes causing sudden hard braking with light pressure. You're also experiencing warning lights (ABS, emergency brake, TSC, tire pressure), a "CHECK VSC SYSTEM" message, and an intermittent buzzing sound from the ABS unit that cycles every ten seconds. This unpredictable braking behavior creates a serious safety hazard, especially in wet weather or heavy traffic. The repair will likely require replacing the ABS assembly, which is an expensive component that may no longer be in production for your model year.

Your brake actuator assembly has failed, which is a known issue affecting many Highlanders. This failure is triggering warning lights on your dashboard and creating a safety risk. The brake actuator assembly will need to be replaced to restore proper brake function and clear the warning lights.

Your car's anti-lock braking system (ABS) module failed, causing a partial loss of braking power while driving. When you tried to stop, you had no hydraulic pressure in the brakes, though the system eventually regained pressure and allowed you to stop safely. This loss of braking capability poses a serious safety risk. Fixing this will likely require diagnosing and replacing the ABS module or related hydraulic brake system components.

Your Highlander's brakes lunge forward instead of stopping smoothly, making the car difficult to control during braking. During a hard braking situation at highway speed, the brakes felt unreliable and unpredictable, creating a serious safety risk. The repair will likely require a brake system inspection and possible replacement of brake components like pads, rotors, or hydraulic system parts.

Your hybrid Highlander's brake actuator may fail prematurely, causing a loss of braking power and creating an unsafe driving situation. Toyota extended the warranty on this part, but many vehicles don't qualify and are still experiencing failures. The part costs around $2,000 plus labor to replace, which can add several hundred dollars more depending on your specific model. Fixing this issue requires replacing the brake actuator with the redesigned version.

When you brake, your vehicle experiences a brief moment where braking force completely disappears as the system switches from regenerative to hydraulic braking. This causes a noticeable surge of acceleration before the hydraulic brakes engage, resulting in longer stopping distances and a near-miss collision when your vehicle continued several feet past a stop line into an intersection. The brake system may need inspection or calibration to ensure smooth transitions between braking modes.

Your ABS brake system threw two fault codes (C1256 and C1391) indicating the ABS brake actuator has failed. During a rainstorm, you temporarily lost all braking power for 1-2 seconds before the system recovered and warning lights appeared on the dashboard. The dealer confirmed the actuator needs to be replaced for safe operation. Fixing this will require replacing the ABS brake actuator unit.

Your Highlander's brake actuator assembly may fail, starting with odd purging sounds when braking at stops. Warning lights for VSC, ABS, and brakes may illuminate, and in severe cases, brakes can fail entirely, creating a serious safety hazard. Toyota has extended warranty coverage on a limited basis rather than issuing a full recall, leaving owners responsible for repair costs of $3,000–$4,500. The fix involves replacing the brake actuator assembly at a Toyota dealership.

Your car is lunging forward when you apply the brakes instead of stopping smoothly. You recently had to replace the ABS module and pump at significant cost, and you believe there was a recall you weren't notified about. The fix will likely involve diagnosing the brake system to identify why the ABS components failed and may require additional brake system repairs or adjustments.

Your ABS module has failed again, even though you replaced it with a genuine Toyota part just over 2 years ago. When you press the brakes, you hear a loud thumping sound, and your car rolls backward when you turn it on before the engine starts—both safety concerns. The ABS module will need to be replaced again, and a mechanic should diagnose why it's failing prematurely.

Your Highlander Hybrid has been making noises when you press the brake pedal for over 2 years, and multiple warning lights have appeared on your dashboard: Check ABS, Check VSC System, Check Brake System, and Brake Malfunction. You've noticed the noise getting louder and lasting longer, and it's taking longer distances to slow down or stop. Fixing this issue will likely require diagnostic testing and may involve replacing brake components, the ABS system, or related sensors.

Your brake system has been malfunctioning over the past couple months. You've already replaced the brake pads and rotors, but the problem persists—likely caused by a faulty brake pump or actuator, which is a known issue in Highlanders like yours. Even though this is a documented problem, your vehicle wasn't included in any recall. Fixing this will require replacing the brake pump or brake actuator assembly.

Your brakes felt unresponsive at first and required extra pressure to engage. Shortly after, your ABS and traction control warning lights came on. A specialist determined your ABS module needs to be replaced. This issue has been reported by other owners with the same year and model vehicle.

Your car shut off completely while driving at highway speed, causing loss of brakes and steering, though it restarted after turning it off and back on. A week later, multiple warning lights appeared (ABS, traction control, brake warning, tire pressure), the brakes became hard to press, and you heard an unusual noise when braking. The dashboard showed "check hybrid system" and "check VSC system" messages. The issue likely involves the hybrid power system and brake control electronics that may need diagnostic scanning and potentially brake system component replacement.

Your car has experienced two critical brake failures. First, while driving, your brake pedal suddenly sank to the floor and your brakes completely failed, forcing you to swerve to avoid a collision and requiring the car to be towed. The brakes briefly returned but failed again within minutes with a loud whistling sound. Second, when you shift into gear after starting the engine, your car involuntarily lurches forward or backward and continues moving even when you're pressing the brake pedal—you have to pump the brakes repeatedly to stop it. Both issues indicate a serious problem with your brake system's hydraulic pressure and control. A mechanic will need to diagnose and repair or replace your brake accumulator, brake master cylinder, and possibly the electronic brake control system.

Your power brakes stopped working while you were driving because the brake actuator failed. Additionally, your vehicle's engine shut down unexpectedly while driving due to a power train system problem. The fix will likely involve replacing the brake actuator and diagnosing the cause of the engine shutdown.

While driving on the highway, your power steering suddenly stops working and the engine shuts off without warning. Your dashboard lights flash and a "Check Hybrid System" warning appears. A mechanic found this may be caused by a faulty electrical connection (solder joint) in the inverter control unit. Disconnecting and reconnecting the battery ground cable temporarily fixes the problem, but it has happened multiple times, creating a serious safety risk if it occurs in traffic.

Your 2006 Highlander was involved in a crash after a front tire blowout. The driver-side airbag deployed, but the front passenger-side airbag failed to deploy, resulting in serious injuries to the passenger including a fractured collarbone, spine damage, and internal injuries requiring multiple surgeries. The driver suffered six fractured ribs. The vehicle was totaled and towed away. This failure occurred at approximately 120,000 miles.

Your engine overheated on the highway and your check engine light came on, forcing you to pull over in heavy traffic. The dealer diagnosed a leaking head gasket with corroded bolts causing coolant and oil to escape, and now recommends replacing the engine at a cost of over $9,000. The fix would involve replacing the engine or at minimum repairing/replacing the head gasket and corroded bolts.

Your driver's side sun visor won't stay up against the roof and keeps falling down, blocking your view of the road. When you push it up, it immediately falls back down. This forces you to either tie it up (which prevents you from using it normally) or deal with the obstruction while driving.
