2017 VOLKSWAGEN GTI Engine Problems

THERE IS A CONSTANT COOLANT LEAK COMING FROM THE THERMOSTAT HOUSING AND WATER PUMP AREA. IT STARTED AS A SLOW LEAK, EVERY 10,000 MILES OR SO I WOULD HAVE TO TOP IT OFF AND NOW IT HAS GOTTEN TO THE POINT WHERE I HAVE TO FILL IT BACK UP EVERY DAY. LOOKED INTO IT ONLINE AND IT SEEMS THAT NEARLY EVERYONE THAT OWNS THIS CAR HAS THE SAME ISSUE AND EVERYONE'S LEAK COMES FROM THIS AREA.THE LEAK HAPPENS AT ALL TIMES BUT IS GREATLY ACCELERATED WHEN DRIVING AND THE COOLANT SYSTEM IS RUNNING.

2017 VW GTI 4 DOOR. SE TRIM. A COUPLE WEEKS AFTER REACHING 40K MILES, AFTER DRIVING SEVERAL BLOCKS AND MAKING IT ONTO A MAIN ROAD, THE VEHICLE STALLED OUT AND DIED WHILE IN MOTION AT ABOUT 20-25MPH. THIS WAS AFTER WHAT SEEMED LIKE A VERY CLUNKY FEELING SHIFTING TRANSMISSION FOR A FEW DAYS LEADING UP TO THE CAR BREAKING DOWN. CAR SMELLED LIKE FUEL IN THE CABIN. CAR NEEDED TO BE TOWED TO VEWDEALERSHIP IN LATE HOURS OF THE EVENING. DEALERSHIP CALLED THE NEXT DAY TO SAY THEY WERE ABLE TO TURN THE CAR ON AND DRIVE IT. NO OBVIOUS ERROR CODES ON VEHICLE AND THEY WOULD DO SOME DEEPER DIVING INTO WHAT CAN BE WRONG. THEY HELD ONTO THE CAR FOR 4 DAYS AND WERE NOT ABLE TO "DUPLICATE THE ISSUE" SO THEY RETURNED THE CAR BACK TO ME. THEY THOUGHT "MAYBE A PIECE OF DIRT GOT INTO A FUEL INJECTOR BUT WORKED IT'S WAY OUT" AFTER NOT EVEN A WEEK, THE CAR STALLED OUT AND DIED IN THE MIDDLE OF A MAIN ROAD AGAIN WHILE MOVING ABOUT 20MPH. THIS TIME AFTER ABOUT 10 MINUTES I WAS ABLE TO GET IT TO TURN ON AND DROVE DIRECTLY BACK TO THE SAME DEALERSHIP WITH BO ERROR FAULT CODES APPEARING ON THE DASH ONCE AGAIN. NO CABIN FUEL SMELL THIS TIME BUT STALLED OUT EXACTLY THE SAME. THEY HAVE BEEN HOLDING ONTO MY VEHICLE AGAIN WITH NO APPARENT IDEAS HOW TO REPAIR IT. THEY ARE GOING TO OPEN A CLAIM WITH VW. THIS WAS A DANGEROUS SITUATION STALLING BOTH TIMES ON MAIN ROADS WHERE I COULD HAVE BEEN REAR ENDED. CHILDREN ARE DRIVEN AROUND IN MY VEHICLE WHICH CAN RESULT IN SERIOUS INJURY.

THE THERMOSTAT HOUSING ON THE ENGINE DEVELOPED A SIGNIFICANT LEAK, ALLOWING COOLANT TO DRIP ON THE ROADWAY AND ALSO ENDANGERING THE CAR'S ENGINE FROM OVERHEATING AND POSSIBLE POWER LOSS. THIS COULD OF COURSE CAUSE A SLIPPERY ROAD SURFACE AND COULD ALSO RESULT IN THE CAR LOSING POWER ON THE STREET CREATING A HAZARD.

THERMOSTAT HOUSING & ASSOCIATED SEALS ON THE CURRENT 1.8L AND 2.0L VOLKSWAGEN/AUDI EA888 GEN 3 ENGINE ARE PRONE TO FAILURE, CAUSING LOSS OF ENGINE COOLANT. THIS COULD AFFECT ANY VW/AUDI VEHICLE USING THE 1.8 OR 2.0L EA888 GEN 3 ENGINE. VW HAS A LONG HISTORY OF WATER PUMP/THERMOSTAT HOUSING ISSUES AND THE CURRENT GENERATION OF VEHICLES IS NO EXCEPTION. MANY OTHER REPORTS CAN BE FOUND ON VARIOUS ONLINE FORUMS SUCH AS REDDIT.COM, GOLFMK7.COM AND VWVORTEX.COM, ETC. THIS IS A COSTLY OUT OF WARRANTY REPAIR REQUIRING REMOVAL OF THE INTAKE MANIFOLD AND HAS BEEN REPORTED ONLINE BY OWNERS OF 2015 '2019 US MY VEHICLES. SOME VEHICLES, SUCH AS OURS, EXPERIENCED A REPEAT FAILURE. THERE ARE THREE FAILURE MODES THAT I AM AWARE OF AS REPORTED ON THE SITES MENTIONED ABOVE. MY WIFE AND I HAVE EXPERIENCED FAILURE MODES 1 AND 2. WHEN THIS ISSUE IS OCCURRING OWNERS OFTEN REPORT THE SMELL OF COOLANT OUTSIDE THE VEHICLE 1. HOUSING HEATING/COOLING CAUSES EXPANSION/CONTRACTION AND WARPING RESULTING IN A SLOW WEEP OR LEAK FROM THERMOSTAT HOUSING ASSEMBLY & ASSOCIATED SEAL, MOST OF THE TIME NOT DETECTABLE AT THE HOUSING ASSEMBLY/SEAL WITHOUT PRESSURE TEST. OFTEN, VW SERVICE CENTERS ARE UNABLE TO VERIFY THERE IS A LEAK, EVEN AFTER PRESSURE TEST, OWNERS ARE SENT ON THEIR WAY, AND YET COOLANT STILL DISAPPEARS FROM THE TANK. MY WIFE'S CAR WENT IN FOR TESTING MULTIPLE TIMES BEFORE ISSUE WAS FOUND. 2. HOUSING HEATING/COOLING CAUSES EXPANSION/CONTRACTION AND WARPING RESULTING IN A SMALL BUT CONSTANT LEAK LARGE ENOUGH TO CREATE A SMALL PUDDLE OR STREAM UNDER THE CAR. A LOW COOLANT ALERT MAY/MAY NOT APPEAR DEPENDING ON SPEED OF THE LEAK. 3. HOUSING HEATING/COOLING CAUSES EXPANSION/CONTRACTION AND WARPING RESULTING IN A SUDDEN CATASTROPHIC FAILURE RESULTING IN RAPID LOSS OF COOLANT AND CAUSING A VISIBLE LARGE PUDDLE UNDER THE CAR AND A WARNING ALERT TO APPEAR ON THE DASHBOARD.
