Twenty 2022 Tundra owners report persistent brake system failures spanning eight distinct problems. Squeaking or squealing noise is the most widespread complaint, present from new through early ownership; dealers acknowledge it's a known material issue under investigation, but parts have been backordered for six months or more.
Brake shuddering and vibration occur when braking, especially downhill or at highway speeds, with rotors warping as early as 30,000 miles—owners note this is abnormal for Tundras. The automatic emergency braking system activates without cause multiple times per vehicle, often at low speeds or from a stop with no obstacle ahead; the system cannot be disabled in some cases. Brake pedal unresponsiveness at highway speeds and malfunction lights during passing maneuvers have been reported, with one owner waiting three years for parts. Electronic parking brake failure and abnormal sounds during reverse also appear.
One owner reports brakes perceived as slow to respond, with an accident occurring on the new owner shortly after trade-in. Owners describe sudden violent stops from the emergency system as terrifying and a serious safety hazard to following traffic. Toyota has issued multiple recalls (22V661000 for hydraulic brakes, 25V657000 for back-over prevention), but parts remain unavailable, leaving owners stranded with known defects despite warranty coverage.
Failure modes owners describe
Squeaking/squealing brakes
Brakes emit squeaking or squealing noise from new or early in ownership. Owners report this is acknowledged by Toyota as a known material issue under investigation, but no parts or remedy available yet despite multi-year waits.
When: From new through early ownership; reported at 4,500 miles, 21,000 miles, and ongoing over 2+ years
Symptoms owners cite: Audible squeaking or squealing from brake system; Persistent noise despite dealership service attempts; No brake performance degradation noted by owners
Repairs/costs cited: Dealership advised as known issue with parts on backorder for 6+ months. One TSB released but parts unavailable after 2-month wait. No permanent fix offered.
Recalls/TSBs owners mention: Toyota acknowledges material issue under investigation; NHTSA Campaign 22V661000 (SERVICE BRAKES, HYDRAULIC) issued
Brake shuddering and vibration during braking
Vehicles shudder, shake, or vibrate noticeably when brakes are applied, especially on downhill grades or at moderate highway speeds. Owners report early rotor warping or degradation.
When: Reported at 21,000–30,000 miles; ongoing at 50–60 mph
Symptoms owners cite: Vehicle shudders or vibrates when brakes applied; Severe vibration especially on downhill grades; Shaking intense enough to affect vehicle control and traffic safety; Rotor warping at 30,000 miles
Repairs/costs cited: Brake pads and rotors replaced at 22,000 miles, out of pocket. Rotors replaced again, still vibrating. Owner notes this is abnormal compared to prior Tundra with 230,000 miles on original rotors.
Recalls/TSBs owners mention: Toyota admits brake parts were faulty and has new part numbers available, but parts remain on backorder indefinitely
Automatic emergency braking system engaging unintentionally
Safety system activates without cause—no vehicle or obstruction in front of truck, often while accelerating from a stop or moving at low speed in traffic. System either cannot be disabled or requires hard pedal pressure to deactivate.
When: At 8,500 miles and repeatedly thereafter; incidents on 6/13/2023 and ongoing
Symptoms owners cite: Emergency brakes engage with no obstacle ahead; Sudden, violent stopping sensation (owner described as 'severe jolt' or 'like being rear-ended'); Occurs when accelerating from stop or moving in traffic; Occurs multiple times across different driving scenarios; System cannot be turned off or disabled by driver per one complaint; Requires hard pedal depression to deactivate per another
Repairs/costs cited: Dealership reset computer on first occurrence, advised problem would not recur—but it did, multiple times. No permanent repair offered.
Brake pedal unresponsiveness or malfunction at highway speed
Brake pedal fails to respond as expected or produces warning signs (squeaking sound, brake malfunction light) when pedal is depressed during passing or acceleration. In one case, brake malfunction light and rear wheel lock reported during passing maneuvers.
When: At approximately 100 miles; incident at 60 mph; incidents during highway passing
Symptoms owners cite: Brake pedal does not respond as needed when depressed at highway speed; Squeaking sound from brakes during malfunction; Brake malfunction light illuminates during passing; Rear wheels lock during passing maneuver; No warning lights in other incident, but squeaking heard
Repairs/costs cited: Dealership ordered brake parts; owner has waited 3 years without repair completion. Diagnosis performed ($189 charged) with no findings. Another dealer charged $600+ for spark plug replacement instead of brake diagnosis.
Recalls/TSBs owners mention: No effective manufacturer response reported; parts remain unavailable
Electronic parking brake malfunction
Parking brake fails to function as intended. Owner received recall notification (Campaign 25V657000) but unable to access service due to remote location.
When: At approximately 60,000 miles
Symptoms owners cite: Electronic parking brake does not function as intended
Repairs/costs cited: No repair completed. Owner located 750 miles from nearest dealer.
Recalls/TSBs owners mention: NHTSA Campaigns 22V501000, 22V661000, 23V142000, 23V566000, 24V125000, 24V381000, 25V657000, 25V322000 issued; manufacturer refused to cover transport costs for repair
Brake responsiveness concerns—possible design flaw
Brake system does not respond quickly enough or brakes perceived as oversized and sluggish. Owner noticed this during rental trial before purchase, raised concern with dealer, and subsequently experienced at least one accident (detected by Toyota system on new owner).
When: Evident during pre-purchase rental and confirmed in owned vehicle
Symptoms owners cite: Brakes do not respond quickly; Brakes perceived as too large; Couple of incidents prior to trade-in; New owner involved in accident shortly after trade-in
Repairs/costs cited: Owner traded vehicle after incidents, losing significant value. No repair attempted.
Abnormal brake noise on reverse
Abnormal sound from brakes when reversing vehicle. Dealership reported brakes operating as designed, no repair performed.
When: Unknown mileage
Symptoms owners cite: Abnormal sound from brakes while reversing
Repairs/costs cited: No repair performed; dealership stated brakes operating as designed.
Recalls/TSBs owners mention: Manufacturer contacted and case filed; no resolution reported
Brake system slamming or impact sensation when stopped
Owners report a slamming motion felt through the truck when stopped at traffic lights or when transitioning gears. Feels like being rear-ended. Unclear if related to automatic emergency brake engagement or separate mechanical issue.
When: At stop light and while shifting from reverse to drive
Symptoms owners cite: Slamming or impact sensation when truck is stopped; Feels like vehicle is being rear-ended; Occurs at red light and during gear shifts
Repairs/costs cited: No repair information provided.
