2020 Volkswagen Tiguan Engine

I am reporting excessive engine oil consumption on my 2020 Volkswagen Tiguan. The vehicle consumes approximately one quart of oil per 1,000 miles. The vehicle has already undergone multiple diagnostic and repair attempts, including PCV-related repairs, all paid by the owner. Despite these repairs, the excessive oil consumption continues. Volkswagen and the dealership have stated that this level of oil consumption is “within range” and have required additional paid testing to further evaluate the issue, even though prior repairs failed to resolve it. I am concerned this reflects a broader engine design or component issue, as similar oil consumption problems have been widely reported by other Tiguan owners. I am submitting this complaint to document the issue and request further review. THE ISSUE OF OIL COSUMPTION WAS REPORTED AFTER THE THIRD OR FOURTH OIL CHANGE BEFORE THE 50,000 MILES WARANTY.

The crankcase breather valve (PCV system) on my 2020 Volkswagen Tiguan failed, which caused catastrophic engine damage. VW Southtown diagnosed the engine as condemned and stated that a full engine replacement is required. Prior to the engine being condemned, I have already spent $3,787.59 in repairs at VW Southtown addressing recurring oil-related issues caused by the PCV valve being stuck closed. This caused an excessive crankcase pressure buildup of over 0.5 psi, as documented on the VW service repair order. The failure occurred while my husband was driving our [XXX] son in the car, and the warning message immediately displayed on the dashboard was: “12V battery not charging. Stop engine.” This sudden loss of engine function and dashboard warning posed a serious safety risk, as it could have resulted in loss of power or control while driving. The problem has been confirmed and documented by an authorized VW service department, including detailed repair orders and technical diagnosis. Prior to failure, there were oil-related warning lights and symptoms of excessive oil pressure, which appeared intermittently and indicated the underlying PCV failure. Research indicates this is a known, widespread issue affecting 2020–2021 Tiguans, with multiple owners reporting breather valve/PCV failures leading to oil loss, excessive crankcase pressure, and engine damage.

Exceeding manufacturer recommended oil consumption. Car emits white smok out of the exhaust upon start up. The vehicle has been in the shop three times for this problem. The first time valve seals were replaced. The second time the oil pressure regulator was replaced the third time the recommended fix is to replace the engine head however they are nationally on backorder for months now so the fix has yet to be applied. Personal research has resulted in numerous Facebook groups and reddit post of customers with the exact same story.

The vehicle has had repeated failures of the oil filter adapter to block gasket. This gasket has been replaced three times in 41,000 miles. There appears to be a failure on the part of the gasket. The vehicle has been repaired for the third time, the gasket remains with the dealership where it was repaired. I do have photos of the gasket. A catastrophic failure would result in radiator fluid pouring out of the vehicle, causing the vehicle to come to a complete stop, regardless of location. This problem has occurred three times within 41,000 miles. The part has been inspected b the mechanic who replaced it. There is no warning other than to watch for leaks.

The vehicle burns oil. When the dealer was confronted they said it was “normal” for the car to burn half a quart of oil every 2000 miles. No oil stains on the ground. The engine is burning the oil.

Low Engine Oil. Car is burning oil. Having to put engine oil every 3 months.

MY 2020 VOLKSWAGON TIGUAN STALLS WHILE IDLING IN TRAFFIC. THE ENGINE MAKES A GRINDING NOISE AND THERE IS NO POWER. I HAVE TO PUT IT IN PARK AND TURN IT OFF AND THEN BACK ON. IT HAPPENED SEVERAL TIMES IN 2021 AND THE DEALER REPLACED THE STARTER-THAT WORKED FOR A WHILE BUT IN THE PAST 7 DAYS (MAY 30, 2022 TO JUNE 6, 2022) IT HAS STALLED 5 TIMES WHILE IDLING IN TRAFFIC.

Complete engine stoppage approximately 18:00 21 July 2021. Headed east on Germany Road, a serpentine two lane road with no shoulder. Engine stopped and vehivle coasted to a stop. I turned on the emergency lights and put the vehicle in park. Fortunately, I was able to restart the car and proceed. It was pure luck that I wasn't rear-ended.

THIS HIGH CONSUMPTION IS TO MUCH.THE LIGHT HAS NOT COME ON YET BUT I DONT LIKE RUNNING IT DOWN TO THE BOTTOM OF THE STICK. I HAD A 2019 TIGUAN AND IT NEVER NEEDED OIL AND HAD OVER 8000 MILES ON IT.I BELIEVE THEY MADE CHANGES TO THE ENGINE AND IM NOT HAPPY WITH IT .THEY NEED TO DO SOMETHIG ABOUT IT SOON. I ALSO HAD A 2014 PASSAT THAT NEVER USED OIL. NO HELP FROM DEALER EXCEPT TO PUT A QUART IN.QUIRK VW QUINCY MA

MY CHANGE OIL SERVICE LIGHT CAME ON AND KEPT REMINDING ME DAILY FOR 10 DAYS THAT I NEEDED AN OIL CHANGE. I TOOK IT TO THE LOCAL DEALERSHIP TODAY AND THEY SAID THEY WOULD ONLY CHANGE THE OIL AT 10,000 MILES. I ONLY HAD 5800 MILES BUT THE OIL WAS LOW SO THEY ADDED OIL. I HAVEN'T EVEN HAD THE CAR 6 MONTHS. WHAT IS WRONG WITH THE NEW ENGINES OR SHOULD THE OIL REALLY BE CHANGED AT 6000 MILES? I SHOULD NOT BE HAVING ISSUES WITH A BRAND NEW VEHICLE. SOMETHING NEEDS TO BE DONE BY VOLKSWAGEN TO CORRECT THIS ISSUE.
