Major recurring service problems with nothing from VW other than a big fat bill each time. For instance, our 1996 VW Passat has been having problems with the Knock Sensor from day 1. The car has been diagnosed and "fixed" for this 4 times under warranty, plus 3 additional times at our expense for the exact same problem, for a total of 7 occurances on a part that several VW personnel and an indep. VW mechanic have told us is VERY UNLIKELY to happen at all, let alone 7 times! VW will do nothing as they claim it is out of warranty. The problem has never been fixed to begin with from when it happened in warranty, as evidenced by VW's own service records.
