Each bar shows the share of total complaints filed at that mileage range. Peak failure window highlighted. Some owners report problems earlier; some make it well past 150,000 miles symptom-free. Maintenance habits and driving conditions shift the curve as much as mileage alone.
What stands out
No new NHTSA brakes complaint has been filed on this vehicle in over 3 years — the issue may be aging out of the active population.
The failure pattern owners describe
Buyer takeaway: Multiple 2021 RAV4 owners report loss of brake pressure, unsafe emergency braking activation, and reduced stopping ability—some incidents resulted in collisions with other vehicles or property. Have any used example inspected by a Toyota dealer for brake system function and ABS/safety system diagnostics before purchase.
Twelve owners describe serious brake issues across 2021 RAV4s, starting as early as 15,900 miles. The most critical complaints involve complete loss of brake pressure—pedal presses to the floor with little or no stopping power. Two owners had accidents: one rolled into a car at a green light and another hit a storefront. In both cases, dealers later confirmed brakes worked, suggesting intermittent faults. Additional reports include sudden emergency braking activation by the pre-collision system without cause, even while reversing from a gas station, causing electrical shutdown and immobility. One owner found braking force drops mid-deceleration on bumpy roads while pedal pressure stays constant. Another reports adaptive cruise control applies excessive braking when the lead vehicle exits the highway, creating rear-end collision risk. A fourth owner describes a seal-barking or farting noise from behind the firewall during braking that worsens from 28,000 to 75,000 miles; the dealer couldn't diagnose it. Other concerns include grinding noise paired with brake warning lights, a parking brake malfunction warning at 4,000 miles, and one instance where the brake pedal felt like the accelerator during snow driving. No factory recalls or technical service bulletins are mentioned in any complaint.

Failure modes owners describe
Loss of brake pressure / brake failure
Brake pedal becomes unresponsive, travels to floor without slowing vehicle. Multiple owners report complete loss of braking ability during normal driving, resulting in collisions.
When: 15,900 to 75,000 miles; occurs without warning during routine driving or emergency stops
Symptoms owners cite: Brake pedal depressed with no deceleration or minimal response; Pedal travels to floor; No warning lights illuminated prior to failure; Forward collision warning and automatic emergency braking also disabled in at least one incident; Parking brake required to stop vehicle in some cases
Repairs/costs cited: Dealers inspected brakes and reported them working normally post-incident in some cases; no diagnosis or repair performed on vehicle in most complaints
Seal noise during braking (master cylinder or booster)
Intermittent barking or farting noise from brake components behind firewall when pedal is pressed or released, particularly during emergency braking. Noise worsens with mileage.
When: Began around 28,000 miles and increased in frequency and volume to 75,000 miles
Symptoms owners cite: Loud seal-barking or farting sound when brake pedal pressed quickly; Sound occurs when brake pedal released; Noise louder and more frequent during hard/emergency braking; Sound occurs randomly but most common during emergency stops
Repairs/costs cited: Dealer unable to help; owner suspects master cylinder, brake actuator pump, or ABS brake pump booster
Unexpected emergency braking activation
Pre-collision system activates emergency braking without apparent cause, including while reversing or on highways with no imminent collision.
When: Occurs during normal driving and reversing; at least one incident reported within 10 minutes of reversing from gas station
Symptoms owners cite: Pre-collision system engages brakes suddenly without driver input; Abrupt braking with noise while vehicle is stationary or reversing; Vehicle becomes stuck/unresponsive for several minutes after event; Electrical system flashes and shuts off during braking event
Repairs/costs cited: No repairs mentioned; owner speculates pre-collision sensor malfunction
Reduced braking force during deceleration on bumpy roads
Braking effectiveness decreases unexpectedly mid-deceleration without change in pedal pressure, particularly when vehicle passes over road bumps.
When: Reproducible on bumpy road surfaces during moderate speed deceleration
Symptoms owners cite: Deceleration rate decreases suddenly without driver releasing brake; Brake pedal depression remains constant but car slows less; Issue occurs specifically when traveling over road bumps during deceleration; Occurs around 10-20 mph while initially braking from 35 mph
Recalls/TSBs owners mention: Similar behavior reported on Toyota Highlander Hybrid forums
Excessive braking from adaptive cruise control
Adaptive cruise control applies excessive braking force when lead vehicle exits highway, forcing following vehicles to brake abruptly and creating rear-end collision risk.
When: Occurs during highway driving with adaptive cruise control engaged at maximum following distance
Symptoms owners cite: Excessive braking force applied when vehicle ahead exits highway; Following vehicles must brake abruptly to avoid collision; Feature creates safety hazard despite otherwise functioning properly
Recalls/TSBs owners mention: Owner reports numerous similar complaints found via internet search
Grinding noise with brake warning light
Brake warning light illuminates while grinding noise heard from front wheel area during driving. Dealer reportedly identified as secondary brake system issue.
When: Occurs during normal highway driving
Symptoms owners cite: Brake warning light illuminated while driving; Grinding sound from front wheels; LTA display warning visible on dashboard
Repairs/costs cited: Dealer identified secondary brake system issue after multiple service visits
Parking brake malfunction warning
Parking brake malfunction warning light displayed on dashboard shortly after purchase with very low mileage.
When: At 4,000 miles
Symptoms owners cite: Parking brake malfunction warning displayed; Warning persists after vehicle power cycle
Brake pedal feels like accelerator (snowy conditions)
During inclement weather, brake pedal depression causes vehicle to accelerate rather than decelerate, reversing during repeated attempts.
When: Occurs during snow driving conditions
Symptoms owners cite: Pressing brake pedal causes vehicle to speed up instead of slow down; Effect repeats on subsequent brake pedal applications
