Volkswagen says that it will recall more than 168,000 VW and Audi models with diesel engines.
There is a defect in the fuel injection system that could cause fuel leaks, possibly creating fire hazards, the company said.
The recall affects certain 2009-12 Jetta mid-sized sedans and wagons, and some 2010-12 Golf compacts, according to the National Highway Traffic Safety Administration (NHTSA).
Some 2010-12 Audi A3 models also are affected, NHTSA said on its Web site.
Models subject to the recall have 2.0-liter diesel engines, NHTSA said.
VW, in documents filed with U.S. regulators, said cracks can develop in the fuel injection system and cause fuel to leak, possibly causing fires.
VW said it is unaware of any fires, accidents or injuries caused by the problem.
On certain VW diesel engines, a vibration caused by the fuel injectors can generate stress that eventually can lead to cracks in the injector fuel lines, VW said in documents filed with NHTSA.
VW will replace a fuel injector line in some models and install dampers to reduce vibration in all affected vehicles, NHTSA said. Both services will be provided free, VW said.
