2023 Toyota Tundra

Component/System Failure: The failure involves the engine cooling system, specifically the radiator, fan shroud, and oil cooling lines. The oil cooling lines are improperly routed or positioned, causing them to press against the plastic fan shroud. Over time, this pressure deforms the shroud inward, leading it to rub against the aluminum radiator and create pinhole leaks. The damaged components are available for inspection upon request. Safety Risk: This defect poses a serious safety risk due to sudden coolant loss and potential engine overheating. This can result in loss of power, engine failure, and unexpected breakdowns in traffic, increasing the risk of accidents, especially at highway speeds. Reproduction/Confirmation: This issue has been widely reported among 2023 Toyota Tundra owners and confirmed through visual inspection by owners and independent mechanics. The consistent nature of the failure indicates a design defect rather than isolated incidents. Inspection History: The vehicle has been inspected, and deformation of the fan shroud along with visible contact and wear on the radiator confirms the issue. Dealerships have acknowledged the condition but refused warranty repairs. Toyota has not issued a Technical Service Bulletin (TSB). Warning Signs/Symptoms: There are typically no warning lights or messages prior to failure. In some cases, coolant loss or overheating occurs only after radiator damage has already developed. Additional Statement: This is a widespread defect caused by improper routing or clearance of oil cooling lines. Despite numerous similar reports, Toyota has not issued a TSB or recall and has denied warranty coverage, leaving owners responsible for repairs related to an apparent design flaw.

Throttle response is unpredictable. From a stop sign, acceleration is difficult to predict. Sometimes a one second delay occures before acceleration power is effected. With the time delay the throttle has been pressed further than normal. In heavy traffic, a collision could be possible. The problem got worse after a firmware update, during a safety recall to replace rearview touch screen. Pedal Lag problem is noted on Toyota Tundra forum.

Manufacturer Recall Number25TB06 NHTSA Recall Number25V322 Date of recall May 15,2025 It has been almost one year since this safety recall and there is still no fix. The manufacturer has failed or is unable to remedy this safety recall for the vehicle in a timely manner. The driver’s view to the rear can be limited when backing during low ambient light conditions, and there may be no indication to others that the vehicle is operating in reverse. This can increase the risk of a crash.

There are 2 recalls on my 2023 Toyota Tunda, one was filed on 5/25/25 (approaching a year ago) and the other was filed on 11/6/25 and there is no remedy yet on either one of these issues. The 11/6/25 recall, on my notice they stated the remedy would be ready at the end of January or early February and there is no remedy yet. The other one from May is approaching a year from the notice. I am concerned that if these both warranted a safety recall, that with so much time passing, it continues to put me and my family's safety on hold while I feel Toyota is dragging their feet and not being held accountable for following through with these known recall issues.

Vehicle is subject to two active safety recalls, both listed as “remedy not available.” One recall involves a potential engine defect related to manufacturing debris, which may result in engine damage and sudden loss of motive power. Manufacturer recall documentation indicates this condition may increase the risk of a stall, particularly under sustained load such as towing or highway operation. A second recall involves reverse lamp failure, which reduces rear visibility and may increase the risk of a crash when backing. No failure event has occurred. However, both safety defects remain unresolved, and no repair or timeline for remedy has been provided. The vehicle is used for towing and hauling, which requires sustained engine load. Due to the risk of engine stall under load and the absence of manufacturer guidance regarding safe operation, use of the vehicle for towing and long-distance travel has been limited. These conditions have been confirmed through manufacturer recall notices. The vehicle has not been repaired because a remedy is not yet available. No warning lights or symptoms have been observed. The concern is based on the nature of the defects described in the recall and the lack of available repair or operational guidance.

The contact owns a 2023 Toyota Tundra. The contact received notification of NHTSA Campaign Number: 25V767000 (Engine and Engine Cooling); however, the part to do the recall repair was not yet available. The local dealer was contacted, but the vehicle was not repaired. The contact stated that the manufacturer had exceeded a reasonable amount of time for the recall repair. The manufacturer was not made aware of the issue. The contact stated that while driving and accelerating, the vehicle briefly lost power. The failure mileage was unavailable.

The vehicle experiences hesitation when starting to move from a stop. So if i come to a stop and pull out into traffic it sometimes hesitates before applying the throttle that has been input via the pedal. This could cause serious injury because its almost impossible to determine when its safe to pull out into traffic because you do not know how long it will take for throttle to kick in.

I am reporting a recurring safety issue with the power windows on my 2023 Toyota Tundra. Specifically: 1.The driver-side window and front passenger-side window have stopped moving partway during operation. The window halts halfway, the window becomes stuck and cannot be closed even when attempting to push the window up manually with my hands. 2.The problem has occurred with two separate windows on the same truck. 3.This behavior has occurred under normal operating conditions and appears similar to reports from other 2023 Tundra owners, suggesting a possible design or manufacturing defect. 4.The issue could pose a safety risk, as the window may trap fingers, limbs, or objects unexpectedly, or fail to close during adverse weather or security situations. Actions Taken: •I have taken the vehicle to a Toyota dealer for inspection and attempted repairs. •The dealer has documented the issue in service records, but the problem has occurred in a different window. Additional Notes: •I am aware of multiple owners experiencing the same issue with 2023 Tundras. •I am submitting this complaint to request that NHTSA investigate the potential defect and assess whether a formal recall or safety advisory is warranted.
