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.

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 vehicle is affected by a manufacturer safety recall # 25TB14 related to the engine. A loss of motive power while driving at higher speeds can increase the risk of a crash. Because of this I have stopped driving the vehicle. According to the recall, The manufacturer has stated that the fix will require replacement of the engine assembly, but the remedy is not yet available and no expected remedy or repair time is given. The vehicle has been inspected by a dealer, who confirmed that the recall applies but could not perform a repair, provide a timeline, or confirm that the vehicle is safe to drive while waiting for the remedy. The manufacturer acknowledged a manufacturing defect and the possibility that the issue could occur without warning. There is no clear safety guidance from the manufacturer, and no loaner vehicle provided. The concern also remains that the vehicle could unexpectedly lose power or stall, putting the driver and others at risk.

My Tundra has been having lagged throttle after takeoff for a few months now going into 2026. My truck is slightly over 50k Miles and did well for the first 40k Miles. Last week it went limp and gave a loss of Power Warning and Check engine light came on. Then the very next day a parking brake assist warning came on. I brought it to the dealer and after 4 days they couldn't replicate the warning light but seen that the Turbo had failure. They said they could not change the Turbo since theres an active Engine recall on my truck. My truck is sitting at the dealer with no committed date or fix for when my engine will be replaced. Not sure what to even do as im paying on a truck i cant even drive. Aside from this major issue ive had two window motors replaced and a non working hamstring leg rest motor. They instead offered to sell me a new 2026 which felt sleazy on their part. I will not be staying with my 2023 Tundra if and when i get it back knowing we only get a 1 year warranty and crate engines are already failing. Toyota is treating their faithful clients horribly on this issue they caused. Id go as far as saying this should be part of the Lemon Law act and more needs to be done.

This is an engine failure recall and after multiple conversations with my service advisor, I am being told that my "vehicle is not ready for the corrective action at this time". When I ask him what constitutes "being ready", he states that "the engine pretty must has to be dead". My reply, "In other words, I need to be stranded with an inoperable vehicle before Toyota is going to allow a claim submission?" His reply, "yep, that is pretty much it." So, I am driving a car over mountain passes every weekend, late at night, just waiting for it to die for a known recall, and Toyota is not taking any action. This car only has 37,700 miles on it and it not what I expected out of purchasing a new Toyota.

While operating my 2023 Toyota Tundra TRD Pro under normal conditions, I started the vehicle and activated standard factory equipment including the seat heaters and window/mirror defrosters. Shortly thereafter, I noticed a slight acrid odor inside the vehicle, which quickly became more pronounced. I drove approximately 200 feet, and immediately returned to my driveway. Upon shutting the vehicle down, I observed smoke coming from the engine compartment. I opened the hood and confirmed smoke and signs of an electrical fire originating in the engine bay. I used a fire extinguisher to extinguish the fire and then disconnected the vehicle’s battery. No injuries occurred. The vehicle was not restarted and was subsequently towed to an authorized Toyota dealership for inspection. Visible damage is present in the engine compartment, including the main fuse/relay box and associated electrical components. The incident occurred without collision and during normal vehicle operation.
