The failure pattern owners describe
The 2005 Sienna has a significant brake defect pattern described across 42 complaints. Owners report premature wear requiring pad and rotor replacement every 10,000–20,000 miles—far shorter than normal. Multiple owners were told by Toyota dealers at initial service (7,500 to 16,000 miles) that brakes already needed replacement. One Toyota service rep acknowledged the van is too heavy for its small braking system.
Complete brake failure is the most serious complaint. Owners describe the pedal sinking to the floor with zero stopping power at highway speeds, in parking lots, and at intersections. Some failures occurred within days or weeks of dealer brake service. Cold-weather brake failure is chronic: first few morning applications fail to engage, clearing only after the engine warms.
The VSC/ABS system engages without cause, automatically applying brakes during normal driving on dry roads and in gentle curves, causing fishtails and loss of control. The parking brake frequently fails to engage despite repeated attempts.
Dealers consistently cannot replicate failures in diagnostics, often blaming the driver or dismissing complaints as normal wear. Some master cylinders were found bypassing or leaking; air was found in brake lines after service. One ABS pump failure cost $1,900 to replace. Owners express grave safety concerns given the frequency of incidents involving children and multiple collision scenarios.

Failure modes owners describe
Premature pad and rotor wear
Brake pads and rotors wear out far faster than normal, requiring replacement every 10,000–20,000 miles or even sooner. Multiple owners report metal-to-metal grinding, scoring of rotors, and complete pad failure at unusually low mileage.
When: 10,000–20,000 mile intervals; as early as 7,500 miles or 15,000–16,000 miles on new vehicles
Symptoms owners cite: metal-to-metal grinding noise; rotors messed up/scored; grinding sound when braking on rough surfaces; pads completely worn or separated from backing plate at low mileage; bad smell from brakes
Repairs/costs cited: Multiple rotor and pad replacements; stuck calipers noted at 16,000 miles; dealers typically charge for these as wear items rather than warranty repairs
Recalls/TSBs owners mention: Toyota told owners this is 'normal wear and tear' despite occurring at 10,000–20,000 mile intervals; one Toyota service rep told an owner the van is too heavy for the small braking system
Complete brake failure under normal driving
Brake pedal becomes unresponsive or goes to the floor without stopping the vehicle. Owners report total loss of braking despite applying hard pressure. Incidents range from slow-speed parking situations to highway speeds.
When: Various mileages; occurs both intermittently and suddenly; often when cold
Symptoms owners cite: brake pedal goes to floor without stopping vehicle; no braking response despite hard pedal pressure; unable to slow or stop in normal distance; no wheel lockup or skid marks evident; loss of all braking control
Repairs/costs cited: Master cylinder replaced in some cases; brake lines bled and air found in all but right rear line in one case; dealers often cannot replicate the issue
Recalls/TSBs owners mention: Dealers cannot duplicate many failures; one owner reported a Toyota service rep attributed the problem to insufficient vacuum until engine warms, recommending 5-minute idle before driving
Intermittent brake failure when cold or after sitting
Brakes fail to respond properly when the engine is cold or the vehicle has been parked. First few brake applications when cold are weak or fail to stop the vehicle; problem clears after driving and warming up.
When: Cold mornings; after vehicle sits for an hour or overnight; first 3–4 brake applications after startup
Symptoms owners cite: non-responsive brakes on first few applications when cold; hard brake pedal with little or no vacuum assist feel; brakes fail to engage when needed to stop at intersections; problem resolves after driving 20–30 miles or once engine warms; brakes function normally on warm restarts
Repairs/costs cited: Master cylinder replaced in at least one case; dealers run diagnostics multiple times without finding fault; one dealership attributed it to new valve timing and recommended idling 5 minutes before driving
Recalls/TSBs owners mention: Dealership diagnostics found no defect in multiple cases; one owner told Toyota they could not duplicate the problem despite leaving vehicle overnight twice
Hard brake pedal with loss of vacuum assist
Brake pedal becomes stiff and difficult to depress, with little or no vacuum-assist sensation. Requires excessive force to slow or stop the vehicle. Occurs intermittently and often after new brake booster installation.
When: Intermittent; occurs after brake booster replacement; affects single wheel (front right noted in one case)
Symptoms owners cite: brake pedal is hard and difficult to depress; little or no vacuum assist; requires excessive pedal pressure to affect braking; front right wheel vibration and wobble noted; bad smell from brakes; vehicle won't roll back in reverse after pedal release
Repairs/costs cited: New brake booster installed; new caliper on right side; front brake lines replaced; brake pads still had material remaining; mechanic unable to identify root cause
VSC/ABS false activation and automatic braking
Vehicle Stability Control (VSC) and anti-lock brake (ABS) systems engage without driver input or legitimate traction loss, applying brakes automatically and causing loss of control or sudden deceleration.
When: On highway curves at 55 mph; on freeway in rain; on various road conditions with or without wet pavement; intermittent occurrences multiple times per driving event
Symptoms owners cite: ABS warning light illuminates; automatic braking without pedal input; vehicle fishtails or veers off roadway; sudden deceleration from highway speed to 35 mph; loss of vehicle control; anti-skid light comes on during normal turning without brakes applied; system activates on gentle curves on dry pavement
Codes mentioned: ABS warning light (stored or intermittent)
Repairs/costs cited: Code readers showed no stored codes in at least one case; brake actuator failure noted in another; ABS pump failure noted in two cases with repair costs around $1,900–$2,000
Brake pedal sinks to floor; master cylinder failure
Brake pedal loses resistance and sinks fully to the floor, often accompanied by total loss of stopping power. Master cylinder bypass or seal failure suspected in multiple cases.
When: At various mileages; can occur suddenly
Symptoms owners cite: brake pedal sinks to floor; no resistance in pedal; no braking effect despite full pedal depression; loss of stopping ability when braking hard
Repairs/costs cited: Master cylinder replaced in multiple cases; one owner's cylinder was found to be 'bypassing'; air in brake lines found in one incident (all lines except right rear)
Brake failure after recent service
Brake failure or malfunction occurs shortly after dealer brake service, rear brake replacement, or other brake-related maintenance, suggesting faulty work or incomplete bleeding.
When: 10 days after rear brake replacement; after oil change service at 1,355 miles; after various brake services
Symptoms owners cite: complete loss of brakes after service; brake failure within days of dealer work; air in brake lines after service
Repairs/costs cited: Air in brake lines found after one incident; dealer bled brakes but could not explain how air entered lines; one failure occurred 10 days after rear brake replacement by Toyota dealer
Brake failure triggered by rough road or bumps
Brakes fail to engage properly when driving over rough surfaces, potholes, or bumpy roads, even at normal speeds. Grinding sound and delayed engagement reported.
When: When driving over bumps, potholes, or rough pavement
Symptoms owners cite: grinding sound when trying to brake on bumpy roads; brake fails to engage immediately on rough surfaces; loss of braking on extremely bumpy roads
Repairs/costs cited: Brake pads replaced and rotors resurfaced multiple times (3–4 dealer visits); issue persisted after repairs despite 76,500 miles and initial failure at 43,000 miles
Parking brake failure to engage
Parking brake does not engage reliably and requires multiple attempts. Often fails to set regardless of vehicle grade or repeated engagement attempts.
When: Intermittent; persistent across different conditions and grades
Symptoms owners cite: parking brake requires multiple attempts to engage; parking brake does not engage at all on many attempts; problem occurs on level and sloped surfaces; issue not related to vehicle grade
