The fuel filler neck and fuel tank junction in a small number of 2021-2023 Acura TLX vehicles may have an incomplete weld that could separate. An incomplete weld can cause separation, leading to a fuel leak while driving or parked. This defect poses a significant risk to vehicle occupants and bystanders, as fuel leaks can ignite and cause fires.
Background of the Issue
Honda first became aware of the issue in November 2023, when they received a warranty claim related to a fuel leak in an affected TLX vehicle. The company promptly launched an investigation, which revealed that a defect related to motor vehicle safety existed. As a result, Honda decided to conduct a safety recall to address the problem. To date, the company has received two warranty claims related to this issue, but fortunately, there have been no reports of injuries, fires, or deaths.
Cause of the Defect
The root cause of the defect lies in the production process of the fuel tank assembly. During manufacturing, the fuel filler neck was improperly loaded into the gripper fixture, resulting in a tilted position and uneven contact between the fuel tank and fuel filler neck during the weld procedure. Additionally, the fuel filler neck melt depth was incorrectly set for the weld equipment, leading to a shallow melt weld depth between the components. This combination of factors created an incomplete weld that can separate over time, allowing fuel to escape.
Symptoms of a Fuel Leak
If you own a 2021-2023 Acura TLX, it’s essential to be aware of the symptoms of a fuel leak. One of the most common signs is a strong gasoline odor wafting through the vehicle while driving. This can be caused by a variety of factors, including worn-out seals, cracked fuel lines, or faulty fuel system components. As cars age, the rubber components in their fuel systems can deteriorate, allowing gas to escape. Common culprits behind these leaks include the fuel pump, filter, and injectors, as well as parts of the emissions system.
Risks Associated with Fuel Leaks
A gasoline smell is not just a minor annoyance; it can also be a sign that your engine is burning more fuel than necessary, which can hit you in the pocketbook. More alarmingly, prolonged exposure to gas fumes can have serious health consequences, including respiratory damage. Given the potential risks to both your wallet and well-being, it’s crucial to address any issues causing a gasoline smell in your TLX promptly.
Recall Details
To rectify the issue, dealers will replace the fuel tank assembly. Owner notification letters are expected to be mailed on February 10, 2025. Acura’s number for this recall is JKX, and the NHTSA campaign number is 24V-950. If you receive a notice for this problem, it’s essential to schedule a service appointment as soon as possible to have the fuel tank assembly replaced.
