The plastic button for the hand brake/ parking brake pops out of the handle which then causes the brake to release. VW has replaced the part under warranty 2 times since I purchased the vehicle. In my case the second time it happened the car popped out of gear and struck 2 cars across the street from my driveway. Dealer states its a common issue. But Volkswagen has done nothing to correct the issue other than replacing the hand brake repeatedly on the cars. It's a major safety issue in my opinion. And I feel they need to come up with a permanent solution rather than replacing with a new faulty part. I have since sold the car back to the dealer as I don't trust that the hand brake on the car won't fail again.
