NHTSA Opens Investigation on 2009 VW Jetta TDI Diesel Models

US government officials have launched an investigation into possible engine problems in the 2009 VW Jetta sedan and Sportwagen TDI diesel models. The National Highway Traffic Safety Administration (NHTSA) said Tuesday it had received seven complaints on the aforementioned models alleging that while driving and without any warning, the engine limped and then stalled almost immediately.

NHTSA said on its website that "a Preliminary Evaluation has been opened to assess the scope, frequency, and potential safety consequences associated with the alleged defect."

According to the safety agency, approximately 37,889 diesel-powered VW Jetta sedan and estate cars might be involved. We'll update this story as soon as new information is available.
