After receiving seven complaints, the National Highway Traffic Safety Administration (NHTSA) has decided to open an investigation into fuel line leaks in some 2011 Volkswagen Jetta and 2011 Volkswagen Jetta Sportswagen vehicles. Drivers complained about leaks at the fuel line to the number two fuel injector on Jetta vehicles equipped with 2.0L TDI common rail diesel engines. Because these engines operate at extremely high fuel injection pressures, the NHTSA’s wants to do a preliminary evaluation to assess the frequency and potential safety consequences of the defect.
