Whether you drive a Tundra or are considering one, understanding this recall is vital for your safety, peace of mind, and long‑term vehicle value.
A. Recall Background and Timeline
A clear chronology helps owners grasp why and when Toyota initiated this safety action:
A. Early Complaints (Late 2024): Several Tundra owners reported a hard brake pedal and reduced braking performance under light vacuum conditions.
B. Manufacturer Investigation (Q1 2025): Toyota’s engineering teams traced the issue to aging vacuum pump gears that wear prematurely.
C. Regulatory Review (March 2025): The National Highway Traffic Safety Administration (NHTSA) opened a probe under Recall ID 25V‑TNDRA to assess field reports.
D. Official Recall Announcement (May 1, 2025): Toyota publicly announced the recall, notifying affected owners via mail and online VIN lookup notices.
E. Repair Campaign Launch (May 15, 2025): Toyota authorized dealers to begin inspecting and replacing vacuum pumps at no cost to owners.
B. Affected Models and VIN Ranges
Not every Tundra is impacted. Identifying eligible vehicles ensures timely remedy:
A. Model Years: 2019, 2020, 2021, and 2022 Toyota Tundra with 3.5L twin‑turbo V6 engines.
B. Drivetrain: Both 4×2 and 4×4 configurations fitted with integrated brake booster pumps.
C. VIN Ranges: Specific 17‑character VIN prefixes starting with “5TF” and “3TFA” through “5TFB,” detailed in Toyota’s bulletin.

E. Geographic Scope: Vehicles sold or registered in the United States, Canada, and Puerto Rico.
C. Technical Cause of Pump Failure
Understanding the mechanical failure offers transparency and context for repairs:
A. Gear Wear: The vacuum pump contains plastic‑reinforced nylon gears; prolonged high‑load operation can abrade gear teeth.
B. Insufficient Lubrication: Factory grease specifications may degrade under extreme heat, reducing gear lifespan.
C. Air Ingress: Microscopic gaps between the housing and gears allow air leaks, lowering vacuum pressure.
D. Brake Booster Impact: Reduced vacuum impairs the brake booster’s ability to amplify pedal force.
E. Delayed Warning: The onboard diagnostic system does not monitor pump health directly, so no warning light appears until brake feel changes noticeably.
D. Symptoms and Early Detection
Owners should watch for these warning signs to prevent dangerous scenarios:
A. Hard Brake Pedal: Increased pedal resistance, requiring more force to achieve normal deceleration.
B. Longer Stopping Distance: Noticeable delay or reduced braking power from standard speeds.
C. Engine Noise: Unusual whirring or grinding sounds from the pump area during engine idle.
D. Hissing Air Noise: Audible air leaks near the brake booster when pressing the brake pedal.
E. ABS Activation: Unexpected ABS cycling at low speeds due to insufficient hydraulic pressure.
F. Brake Warning Light (Rare): In some cases, the master warning lamp may illuminate after severe vacuum loss.
E. Safety Risks and Incident Reports
Brake assist failures can have serious consequences; real‑world events highlight the gravity:
A. Collision Reports: NHTSA notes at least ten incidents where Tundras experienced degraded braking before minor collisions.
B. Near‑Miss Events: Drivers reported narrowly avoiding obstacles when the brake pedal stiffened unexpectedly.
C. Injury Cases: Two occupants sustained minor injuries from abrupt emergency stops following pump failure.
D. Property Damage: Rear‑end fender benders and parking lot mishaps rose among affected VINs.
E. Consumer Alerts: Enthusiast forums buzzed with owner testimonials urging Toyota to expedite repairs.
F. Toyota’s Repair Procedure
Toyota dealers will execute a standardized remedy at no charge to owners:
A. Vacuum Pump Inspection: Technicians verify gear integrity, lubrication condition, and vacuum pressure levels.
B. Pump Replacement: Defective vacuum pump assemblies are swapped for updated units with reinforced gear materials.
C. Brake System Bleed: A complete brake fluid flush ensures removal of air pockets introduced during pump removal.
D. Software Update: ECU brake‑control software is flashed to refine pump failure detection thresholds.
E. Quality Verification: Post‑repair road tests confirm restored pedal travel and vacuum levels meet factory specifications.
G. Owner Action Plan
Taking prompt action maximizes safety and preserves vehicle value:
A. Verify VIN Status: Use Toyota’s online recall lookup tool or NHTSA’s portal to confirm eligibility.
B. Schedule Service: Contact your local Toyota dealer, reference Recall 25V‑TNDRA, and set up an appointment.
C. Transportation Options: Inquire about courtesy loaner vehicles or shuttle services if repairs extend beyond half a day.
D. Document Repairs: Keep all service receipts and recall completion certificates for resale transparency.
E. Monitor Post‑Repair Performance: Report any residual brake feel issues to Toyota Customer Experience for follow‑up.
H. Legal Rights and Warranty Extensions
Owners should understand statutory protections and additional coverage offered by Toyota:
A. Federal Recall Law: Under the Motor Vehicle Safety Act, manufacturers must remedy safety defects at no cost.

C. Warranty Extension: Toyota extends the powertrain warranty by two years/24,000 miles for brake pump assemblies.
D. Reimbursement Claims: Owners who paid for independent repairs before the recall may seek reimbursement with valid invoices.
E. Class Action Potential: Groups of owners may pursue legal action if Toyota’s remedy proves inadequate.
I. Preventive Maintenance Tips
Beyond the recall, proactive care helps maintain optimal brake performance:
A. Regular Fluid Changes: Replace brake fluid every 30,000 miles or two years to prevent moisture build‑up.
B. Visual Inspections: Check vacuum pump hoses and connectors for cracks, kinks, or deterioration.
C. Lubrication Checks: Ensure factory‑specified grease remains present around gear housings.
D. Climate Considerations: Park indoors when possible to minimize heat‑related lubricant breakdown.
E. Test Brakes Safely: Periodically perform gentle brake tests in empty lots after highway driving to feel for stiffness.
