I've seen posts regarding temperature being colder, but I'm in South Florida, so doesn't apply. One thing both the shop foreman and I both noticed is that it happens more often with longer drives. short skips and hops don't usually generate it. it does seem though that many of have a very specific, and identical issue. we've all been to the shops, and they invariably would have tried different things, and have opened a PUMA case. At this point, doesn't look like they have a fix yet!
