2008 VOLKSWAGEN RABBIT Structurebody Problems

IN MOTION: THE TRANSMISSION IS NOT PROPERLY SHIFTING UP. THERE IS DELAY, THEREFORE THE CAR IS 'JUMPING' BEFORE THE HIGHER LEVEL OF GEAR AUTOMATICALLY SHIFT. THIS PROBLEM LAST FOR ABOUT 4 MONTHS IN MOTION: THE USE OF FUEL IS MUCH HIGHER THAN USED TO BE, EVEN ALL INJECTORS ARE PROPERLY WORKING. THIS PROBLEM IS NOW ABOUT 5 MONTHS OLD. THE REAR DOOR - ITS LATCH BROKE IN NOVEMBER 2014. THE DOOR FELT ON MY HEAD. CONTACTING VW USA - I WAS TOLD THAT THE REPAIR HAS TO BE DONE BY VW DEALER.. VW DEALER MADE ME A QUOTE OF $ 3.5 K WHICH I REJECTED. SINCE THAT TIME I AM CARRYING IN CAR BOARD OF WOOD AND USING IT FOR SUPPORT OF OPEN DOOR.

WAS IN A TIGHT SPOT AT A PARKING LOT, WHEN I WAS BACKING UP I HIT A BARRIER BEHIND ME, AFTER STOPPING AND SHIFTING TO GO FORWARD, THE CAR SPED UP UNCONTROLLABLY UNTIL IT CRASHED INTO A WALL IN FRONT. THE SPACE AND TIME WAS VERY SMALL/SHORT, BUT THE FORCE WAS SO RAPID THAT THE AIRBAGS WERE DEPLOYED.
