NHTSA said that its Office of Defects Investigation (ODI) has received seven complaints from those with 2009 Jetta TDI models, claiming that the engine hesitated and then stalled almost immediately, without warning. Potentially, a preliminary investigation could lead to a recall.
Altogether, it could affect up to 27,889 vehicles, according to the Detroit News.
The investigation covers both Jetta TDI and Jetta SportWagon TDI models, which share nearly all the same mechanical components, and the agency is considering it to be a potential fuel-system issue. A description of the issue details, "Engine stalls due to fuel system contamination," and the Detroit News, citing www.tdiclub.com, reports an issue with metal-flake contamination.
