The National Highway Traffic Safety Administration has opened an investigation into Volkswagen Passat sedans and wagons built between 2001 and 2007. According to NHTSA, a total of 35 complaints have been filed regarding ignition coils that have malfunctioned, 14 of which resulted in an underhood fire.
If this sounds familiar, that's because this is the second such investigation opened by NHTSA. The first centered around models built only in 2002 and 2003; this second investigation has been opened and expanded to include all model-year 2001-2007 Passats due to additional customer complaints.
Details on the investigation from NHTSA can be found in the report after the break.
