2011 VW Jetta

The National Highway Traffic Safety Administration is investigating 2011 Volkswagen Jetta TDI and Jetta SportWagen TDI diesel vehicles for a possible fuel line leak. NHTSA says its Office of Defects Investigation has received seven owner complaints of fuel leakage from the fuel line to one of the fuel injectors in these two models. Affected vehicles have a 2.0-liter TDI common rail diesel engine. NHTSA says the diesel engine’s “fuel system … operates at extremely high fuel injection pressure.”

The complaints report that the fuel leak happens between the 2,470 to 7,764 mile marks. Autoblog says about 40,000 VW Jetta TDI models are included in the investigation. NHTSA says it also received one complaint for fuel leakage in a Volkswagen Golf with the same 2.0-liter diesel engine, for which it has opened a preliminary evaluation.

It can take NHTSA up to a year to decide whether or not to issue a formal recall. If a recall is issued, Volkswagen will notify owners of affected vehicles. If you have questions, you can call NHTSA’s vehicle safety hotline at 1-888-327-4236 or visit http://www.safercar.gov .
