Laguna Hills, CA – December 27, 2018 – Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2018 Volkswagen Golf R vehicles due to a potential fuel leak. Recalled vehicles have been manufactured with fuel lines built in a specific time period with dimensional deviations that may affect the correct function of the guiding sleeve. The potential number of units affected is 516.
The Defect
According to the NHTSA Recall Safety Report, due to dimensional deviations at the fuel line, the guiding sleeve that is used in production to support the assembly of the quick connector may be distorted. If this happens, the connection may appear securely locked due to friction (caused by the distorted guiding sleeve) instead of being positively locked. Because of this defect, the underhood fuel supply hose quick connector may not be securely attached to the fuel supply line.
There is a risk that the fuel line may open at the quick connector, causing it to detach from the fuel supply line in the engine bay. This can result in a fuel leak which may cause fuel to enter into the engine compartment. A fuel leak in the engine compartment (and thus in the presence of an ignition source) can increase the risk of a fire. The customer may recognize a fuel odor in the vehicle if a leak occurs.
Timeline of Events
On June 23, 2018, the first loose connection was found in the field and analysis process started immediately with the first checks in factory conducted. On August 08, 2018, the first claimed field parts were received and deeper part analysis started. Between August 08, 2018 and November 05, 2018, there was intensive testing and analysis process carried out to identify the root cause of the issue.
