What stands out
Owners have filed 65 brakes complaints with NHTSA against this vehicle, but no formal recall covers the issue — the federal record reflects what manufacturers have admitted, not everything owners are reporting.
Among the 20 model years of Toyota Highlander in our records for brakes problems, this one ranks #2 by owner-complaint volume.
Is there a fix? Manufacturer service bulletins
The manufacturer has issued service bulletins covering brakes on this vehicle — documented repair instructions, service campaigns, or warranty extensions sent to dealers. A TSB isn't a recall (it's not a free safety remedy), but it's the manufacturer acknowledging the issue and how to fix it.

The failure pattern owners describe
The 2008 Highlander brake system shows a pattern of actuator and booster pump failure tied to internal leaks and seal degradation. Owners describe the problem onset with grinding sounds, soft pedals requiring excessive travel before engagement, and dashboard warnings: "Brake Malfunction," "Check ABS," "Check VSC System." Diagnostic code C1391 (accumulator pressure leak) is the smoking gun. One owner had the code appear first in 2020, got dismissed as a battery issue, and the same code returned a year later.
Toyota issued Customer Support Program Bulletin POL19-06 in June 2019, acknowledging internal malfunctions in the brake actuator assembly on 2008–2010 Hybrid models. It covered repairs free through December 31, 2020, then secondary coverage to 10 years or 150,000 miles. The catch: most 2008 owners are now beyond both windows. Repair costs hover around $3,000–$4,200 for the actuator and booster replacement.
The real sting is that earlier models (2006–2007) got a full recall for the identical defect, but Toyota stopped short of recalling 2008s. One owner had new "improved" parts installed in 2022 under the program, only to see the same C1391 failure in October 2024 at 20,000 miles. Toyota could not explain why the replacement failed so quickly.
Owners also report isolated brake booster bursts, master cylinder seal leaks, and intermittent ABS/VSC glitches that reduce stopping power during emergency stops. One driver nearly hit another vehicle when brakes faded; another had the brake booster burst and accelerate instead of brake at 53,000 miles.

Failure modes owners describe
Brake actuator assembly failure with internal fluid leak
The brake actuator assembly develops internal leaks in the accumulator chamber, causing loss of brake pressure and system malfunction. This is the primary failure mode affecting 2008-2010 Highlander Hybrids, documented in Toyota's own Customer Support Program bulletin POL19-06.
When: Varies from 53,000 to 184,000+ miles; most failures reported after 5-12 years of ownership
Symptoms owners cite: Brake Malfunction warning message with instruction to stop immediately; Check ABS, Check VSC System, Check Brake System warning messages; Multiple warning lights: brake system light (red), ABS light, VSC light, SLIP indicator, master warning light; Soft or spongy brake pedal with excessive travel before engagement; Grinding or squeaking noise when braking; Intermittent loss of brake pressure requiring harder pedal pressure
Codes mentioned: C1391 (Abnormal Leak in Accumulator Pressure), C1252 (Pump Motor Relay), C1253 (Pump Motor Relay malfunction), C1256
Repairs/costs cited: Replacement of brake actuator assembly (part 04008-26448) and brake booster pump assembly (part 04008-51148). Owners report repair costs of $2,700–$4,200, typically requiring Toyota dealership service due to proprietary software and calibration requirements.
Recalls/TSBs owners mention: Toyota Customer Support Program Bulletin POL19-06 (issued June 6, 2019, revised August 28, 2019) offered repair coverage until December 31, 2020 (primary) and 10 years/150,000 miles from first use (secondary). Coverage has expired for most 2008 model owners. Toyota declined to issue a full recall, instead limiting coverage by expiration date and mileage thresholds. Earlier model years (2006–2007) received recalls for the same defect.
Master cylinder and brake booster seal failure
Brake fluid leaks occur between the master cylinder and brake booster due to failed seals, causing brake fluid to migrate into the booster chamber and rendering the braking system non-functional.
When: As early as 5 years and 78,420 miles; typically within first decade of ownership
Symptoms owners cite: Brake pedal goes to floor with no resistance; Brake fluid leak visible in brake booster; Brake warning light illuminated; Complete loss of brake pressure; emergency brake required to stop vehicle; Vehicle will not shift out of Park without brake pressure
Repairs/costs cited: Replacement of both master cylinder and brake booster. One documented case cost involved labor and parts replacement after fluid was found entirely in the brake booster.
ABS/VSC system intermittent malfunction and brake fade
The ABS and vehicle stability control systems activate prematurely or malfunction, reducing available braking power at critical moments. Brake pedal response is delayed or inconsistent, requiring extra pressure to engage brakes.
When: Early ownership through higher mileage; some owners report from first weeks of ownership
Symptoms owners cite: Soft or spongy brake pedal with excessive dead travel (approximately 1 inch) before brakes engage; Premature ABS activation during normal braking; Brake fade and reduced stopping power; Vehicle does not stop smoothly; requires full-body pressure on pedal; Brake surging forward when pedal released
Codes mentioned: C1391
Repairs/costs cited: Root cause often traced to brake actuator or accumulator failure. Some owners report that routinely pressing the brake pedal until the VSC light comes on temporarily reduces pedal travel, suggesting system pressure regulation issue.
Recalls/TSBs owners mention: Dealers have dismissed complaints as normal operation and within specification, even when multiple owner reports describe dangerous braking conditions. Toyota dealerships state that excessive pedal travel and VSC engagement are design characteristics.
Brake booster pump assembly failure
The brake booster pump assembly (accumulator and motor) fails, resulting in loss of brake assist and pressure. This failure often occurs without warning.
When: Various mileages; one documented case at 53,000 miles
Symptoms owners cite: Brake booster burst or failed pump motor; Loss of brake assist; Vehicle accelerates instead of slowing when brakes applied; Brake warning lights and messages display
Repairs/costs cited: Replacement of brake booster pump assembly. One case documented partial coverage (50%) from manufacturer after failed booster at 53,000 miles.
Recalls/TSBs owners mention: One owner reported manufacturer paid 50% of repair costs; however, most recent cases show no coverage due to program expiration.
Brake system pressure loss and recurrent actuator failures
Even after replacement of the brake actuator assembly with newer parts (as covered under the 2019 recall/program), the same failure mode recurs within a short time, suggesting either a systemic design flaw or inadequate replacement parts.
When: Recurrence documented within 20,000 miles of replacement; one case showed second failure within 20 months
Symptoms owners cite: Same C1391 code and warning messages recurring shortly after repair; Brake system pressure loss reappears; Warning lights return despite recent replacement
Codes mentioned: C1391
Repairs/costs cited: One owner had new 'improved' parts installed in March 2022 (per the recall program) but experienced identical failure by October 2024 (approximately 20,000 miles later). Toyota acknowledged use of new parts but could not explain premature failure.
Recalls/TSBs owners mention: Toyota confirmed use of new parts from the recall program but declined further explanation or coverage for repeated failure.
Brake pedal sticking and stuck-in-Park condition
Brake pedal becomes stuck or difficult to release during braking, and vehicle transmission will not shift out of Park without brake pressure.
When: Documented at 130,000 miles
Symptoms owners cite: Brake pedal sticks and requires multiple depressions to release; Check Engine and Brake warning lights illuminate; Shifter locked in Park position
Repairs/costs cited: Brake booster replacement required in documented case.
Right front brake popping and locking
The right front brake makes a loud popping sound when backing up or braking, consistent with caliper or brake assembly shift or locking. Issue present from new vehicle delivery and worsens over time.
When: From delivery in December 2008; progressive worsening over ownership
Symptoms owners cite: Loud popping noise from right front brake, especially during backing up; Sensation of brake locking up; Noise only from right front brake, not other wheels; Issue not present on left side or other brakes
Repairs/costs cited: Not repaired in documented complaint. Toyota dealership dismissed as normal 'brake shifting' and declined further service.
Recalls/TSBs owners mention: Dealership denied any defect, stating the noise is normal and that the brake is merely 'shifting.' When vehicle went out of warranty, dealership demanded diagnostic fee ($45) to re-evaluate.

While driving at 35 miles per hour, the brake light on the dashboard came on, brake pedal began going all the way down while braking, and the brake pedal began making noise. I stopped the car, open the hood and found that all my brake fluid was gone. The Toyota dealership was nearby I drove the car slowly to the dealership. They checked the brake system only to find out that all the brake fluid…
After researching online, I have noticed this is a very common issue and Toyota issued recalls out for 2006 & 2007 but has not acknowledged 2008 as having the same issue. I was almost in an accident and noticed there are others out there that have been in accidents. Why is it that nothing has been done to correct this? First, I heard an airy sound when braking then a soft brake pedal before…
