@ Nicksey:
My question was: "Our 2021 Jazz EX experienced none of these failures. I wonder how many forum members here can say the same."
There is a poll "Which Mk4 Jazz do you own?" and total 267members voted. This means that 267 forum members own a Mk4 Jazz. Some have been confronted with the failures mentioned. Among them Nicksey.
But what I asked about: how many of those 267 are not confronted with these failures...
