2018 Volkswagen GTI Powertrain & Transmission Problems

AN ISSUE EXISTS WHERE THE START STOP SYSTEM (S/S) CAN CAUSE THE VEHICLE TO STALL AT A STOP LIGHT. AT ONE POINT, THE DRIVER WAS IN STOPPED IN TRAFFIC, WHICH CAUSED MY S/S TO ACTIVATE, TURNING OFF THE VEHICLE'S ENGINE. THE DRIVER UNBUCKLED HIS SEAT BELT SO HE COULD PUT SOMETHING INTO THE GLOVE BOX, THEN RE BUCKLED HIS SEAT BELT. TRAFFIC BEGAN MOVING AGAIN, SO THE DRIVER HIT THE ACCELERATOR. THE VEHICLE DID NOT ACCELERATE. THERE WAS A NOTIFICATION ON THE DASH STATING "PLEASE START ENGINE MANUALLY". THE DRIVER ATTEMPTED TO START THE ENGINE, BUT THE VEHICLE WAS STILL IN DRIVE, SO THE VEHICLE NOTIFIED HIM TO PUT THE TRANSMISSION INTO P OR N. THE DRIVER SHIFTED THE VEHICLE INTO N, RESTARTED THE ENGINE, SHIFTED BACK INTO DRIVE AND THEN RESUMED DRIVING. (AFTER CREATING A SMALL TRAFFIC JAM) LATER, THE DRIVER TOOK THE VEHICLE TO THE DEALERSHIP AND EXPLAINED THE ISSUE. THE SERVICE DEPARTMENT POLITELY EXPLAINED THAT THE S/S SYSTEM DOES THAT, AND THERE IS NOTHING THAT THEY CAN DO. THEY EXPLAINED THAT MULTIPLE FACTORS STIPULATE THE S/S SYSTEM'S DECISIONS, SUCH AS ENGINE TEMPERATURE, POWER CONSUMPTION (JUST TO NAME A FEW). THE DRIVER ALSO ASKED IF THE DEALERSHIP COULD JUST REMOVE S/S SYSTEM, THEY EXPLAINED THAT THEY WERE NOT ALLOWED TO DUE TO EPA REGULATIONS. ATTACHED IS A PNG FILE CONTAINING SCREENSHOTS OF A MP4 THAT THE DRIVER TOOK ON 03/01/20 WHILE ATTEMPTING TO RECREATE THE INCIDENT. IT SHOULD BE NOTED THAT THE DRIVER COULD NOT RECREATE THE INCIDENT PERFECTLY. THE DRIVER WAS ONLY ABLE TO MAKE IT SO THAT THE S/S MECHANISM WOULD RESTART THE ENGINE AFTER THE DRIVER RE BUCKLED HIS SEAT BELT AND SUBSEQUENTLY DEPRESSED THE ACCELERATOR MOST OF THE WAY DOWN (NOT REQUIRING THE DRIVER TO SHIFT THE VEHICLE INTO P OR N AND RESTARTING THE ENGINE).

TL* THE CONTACT OWNS A 2018 VOLKSWAGEN GTI. WHILE DRIVING, THE VEHICLE LOST POWER AND ACCELERATED SLOWER THAN NORMAL. IN ADDITION, THE CHECK ENGINE WARNING INDICATOR ILLUMINATED. WHEN THE VEHICLE WAS POWERED OFF AND RESTARTED, THE FAILURE REMAINED. THE CONTACT WAS A CERTIFIED MECHANIC AND STATED THAT HE USED VOLKSWAGEN FACTORY SOFTWARE TO DIAGNOSE THE VEHICLE. THE CONTACT FOUND FAILURE CODES PERTAINING TO THE LOSS OF CAMSHAFT SYNCHRONIZATION AND FAILURE OF CYLINDER TWO. THE VEHICLE WAS NOT TAKEN TO A DEALER AND WAS NOT REPAIRED. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE AND REFERRED THE CONTACT TO NHTSA. THE APPROXIMATE FAILURE MILEAGE WAS 10,000.

WHEN DOWN SHIFTING THE TRANSMISSION SHIFTS ROUGHLY. (ONLY IN TRAFFIC) WHEN DOWN SHIFTING FROM 3,2,1 THE BRAKE PEDAL FOR SOME REASON DECIDES TO BRAKE HARDER THAN SUPPOSED TO, MAKING THE CAR JERKY. ( REGULAR DRIVING AND COMING UP TO A STOP LIGHT. ) AUTOMATIC TRANSMISSION AND IT'S THE AUTOBAHN EDITION.. ALSO WHEN THE CAR IS IDLING (COLD START) THE ENGINE VIBRATES ALOT MORE THAN NORMAL
