Toyota Tundra Fuel Leak: Safety Alert

Certain models of the 2022-2023 Toyota Tundra and Tundra Hybrid vehicles are facing a potential fuel leak issue involving the fuel line positioned over the fuel tank. This situation poses a risk of vehicle fires if a fuel leak combines with an ignition source.

Toyota detected this concern in November 2022 when a customer's vehicle was reported to be leaking fuel from the fuel tube located atop the fuel tank assembly. The investigation revealed that the fuel tube had been in contact with the frame rail, prompting further examination.

In collaboration with the fuel tube supplier, Toyota delved into the issue by assessing recovered fuel tubes and scrutinizing the fuel tube manufacturing process. An audit unveiled that both new and recovered fuel tubes did not meet specifications, with an irregular shape. A survey was conducted to identify vehicles in the field with a similar fuel tube-brake line contact issue. It was found that over half of the vehicles displayed this contact condition.

The affected vehicles feature a plastic fuel tube that deviates from specifications. This tube is positioned close to a metallic brake line on the upper part of the fuel tank, secured by a clamp. Under certain driving conditions, the clamp can lead to contact between the fuel tube and the nearby brake line. Over time, the friction from driving-induced vibrations may result in the fuel tube rubbing against the brake line, causing a potential fuel leak. Drivers might notice a fuel smell while driving or while the vehicle is parked, and a fuel leak could become visible around the right rear wheel area.

To address this issue, dealerships will temporarily install protective materials and a clamp on the fuel tube. Once the permanent solution is ready, dealers will replace the fuel tube. Toyota has assigned the recall the numbers 23TB09/23TA09, and the National Highway Traffic Safety Administration (NHTSA) campaign number is 23V-566. This measure aims to ensure the safety of Toyota Tundra owners and prevent any risks associated with fuel leaks and potential fires.
