This is a huge problem with most 2012 Beetle. VW has been working on a fix but 8 months after launch, nothing has worked. My car has been in the shop 2 out of the first 8 months and this is one of the issues they have not been able to fix. To date VW has replaced the motors 2 times along with gears and other items they did not detail. This is what still happens after all the repairs. This is also one of 3 beetles I used with the same issue.
