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.

DISCOVERED COOLANT LEAK ON OIL PAN AND CONTACTED DEALERSHIP. THIS WAS DURING ROUTINE INSPECTION. DEALERSHIP INSPECTION REVEALED A FAILED WATER PUMP HOUSING. DEALERSHIP REPLACED HOUSING, THERMOSTAT AND THERMOSTAT GASKET UNDER WARRANTY.

TL* THE CONTACT OWNS A 2017 VOLKSWAGEN GTI. THE CONTACT STATED THAT THE VEHICLE WAS LEAKING FUEL AT A RATE OF ONE GALLON OF FUEL EVERY FIVE MINUTES. THE VEHICLE WAS TAKEN TO AN INDEPENDENT MECHANIC TO BE DIAGNOSED. THE CONTACT WAS INFORMED THAT THE CHARCOAL CANISTER AND SUCTION PUMP NEEDED TO BE REPLACED. CHAPMAN VOLKSWAGEN OF TUCSON (4500 E 22ND ST, TUCSON, AZ 85711) WAS CONTACTED AND INFORMED OF THE FAILURE. THE CONTACT WAS REFERRED TO THE MANUFACTURER FOR ASSISTANCE. THE MANUFACTURER WAS NOTIFIED OF THE FAILURE BUT PROVIDED NO ASSISTANCE. THE VEHICLE WAS NOT REPAIRED. THE FAILURE MILEAGE WAS 90,000.

THERMOSTAT HOUSING LEAK CAUSES COOLANT LEAK AND LOW COOLANT WARNINGS. WAS OPERATING THE VEHICLE UNDER NORMAL CONDITIONS WHEN LOW COOLANT WARNING ILLUMINATED.

CAR SUFFERED A FAILURE OF THE THERMOSTAT AT 26837 MILES CAUSING A LOSS OF COOLANT. COOLANT ODOR WAS APPARENT SINCE THE CAR WAS NEW. THIS APPEARS TO BE A WIDESPREAD PROBLEM WITH THIS MODEL AT LOW MILEAGE.

AFTER 55K MILES, MY CAR HAD A WATERPUMP LEAK THAT SEEMS COMMON IN THE FORUMS I ATTEND.

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...

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.

ENGINE IS LOSING COOLANT. STARTED AT ~50K MILES MARKED. COOLANT NEEDS TO BE TOPPED OFF. NOW THE CAR IS AT 71K MILES. LOW COOLANT TRIGGERED WARNING LIGHT AGAIN! COOLANT NEEDS TO BE TOPPED OFF. THERE APPEARS TO BE WHITE CRUSTY MARKED NEAR THE ENGINE OIL PAN AND SEEM TO BE COMING OFF FROM THE THERMOSTAT HOUSING.

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...

NOTICED BURNING COOLANT SMELL COMING FROM THE ENGINE COMPARTMENT AFTER THE VEHICLE REACHED OPERATING TEMPERATURE AND THE CAR WAS STOPPED. COULD HEAR A SIZZLING NOISE WITH THE ENGINE OFF AND THE HOOD OPEN. THE COOLANT LEVEL WAS AT THE MINIMUM LINE. THE DEALER DIAGNOSED A LEAKING THERMOSTAT HOUSING. DEALERSHIP REPLACED THE PART UNDER WARRANTY. THE REPAIR WAS PERFORMED AT 34,655 MILES.

THE "COMBI" VALVE ON MY GTI STAYS STUCK OPEN CAUSING MORE EXHAUST GASES TO FLOW THROUGH THE CATALYTIC CONVERTER. AS A RESULT NMY CATALYTIC CONVERTER HAD TO BE REPLACED. AFTER REPLACING TO COMBI VALVE. IT HAPPENED AGAIN
