Last March I shared some preliminary car reliability stats for the FIAT 500 and new Volkswagen Passat. The 500 looked very good at the time. The Passat was at the other extreme. Another three months have passed, and TrueDelta’s car reliability stats have been updated to include owner experiences through the end of March 2012. In these updated stats, the FIAT remains excellent while the Passat has improved. But in J.D. Power’s annual Initial Quality Survey (IQS), released yesterday, they’re both awful. What gives?
