Having owned 2 and 6 wagon loaners over the past year.....There are many causes of the pano leaks: weld defect, spider traps getting clogged, pinched rear tubes, rail attachment not fully sealed, antenna seal and rear hatch drain tube issue. As you can see our
Alltrack has many QC and poor build quality issues. The main issue for the 2017 and early 2018s was the weld defect as noted in the VW pano leak TSB, but the latter problems still exist in the latter model years. On the later 2018 and 2019 If you take out the spider traps and make sure the rear drain tubes are routed properly you probably have a better than 50/50 chance it won’t leak. My 2019 is 7 months old now and no leaks.......so far.
