VW CUSTOMER # 06426725. REAR HATCHBACK OPENED TWO (2) TIMES ALL BY ITSELF WHILE PARKED IN MY GARAGE OVERNIGHT. THE HATCH DOOR COULD NOT OPEN ALL THE WAY UP BECAUSE IT CAME IN CONTACT WITH MY GARAGE DOOR. SINCE I WAS NOT READILY ABLE TO SEE THE HATCH WAS OPEN, IT WAS OPEN ENOUGH TO COME IN CONTACT WITH MY GARAGE DOOR WHEN I OPENED THE GARAGE DOOR FROM THE GARAGE DOOR BUTTON AT THE FRONT OF THE TIGUAN. NOW MY GARAGE DOOR IS DAMAGED AND MY VW TIGUAN REAR HATCH DOOR IS BENT BUT STILL OPERATIONAL. VW CUSTOMER SERVICE REGION HAS OFFERED NO HELP OR ASSISTANCE TO ALLOW THE VW DEALER TO FURTHER INVESTIGATE THE PROBLEM. I AM APPALLED THE THE NATSHA HAS NOT INVESTIGATED THIS FURTHER AS I KNOW IT HAS BEEN HAPPENING WITH OTHER VW TIGUANS. IF CHILDREN SIT AT THE REAR HATCH WHILE DRIVING, THEN THE CHILD MAY FALL OUT OF THE VEHICLE AND END UP AS A FATALITY. IF A LARGE BAG OF DOG FOOD FALLS OUT THEN IT COULD CAUSE A FATALITY FOR THE VEHICLES BEHIND THE VW TIGUAN. THE FRONT WARNING/BRAKE ASSIST ENGAGES AT LOW SPEEDS WHEN GOING DOWN A SMALL CREST DOWNWARD TO EXIT A PLACE OF BUSINESS ONTO A STREET. AGAIN VW DEALER LOOKED BUT COULD NOT REPLICATE. THIS UNWANTED STOP CAN RESULT IN A FATALITY IF THE DRIVER IS REQUIRED TO MERGE QUICKLY ONTO A MAJOR ROAD.
