2020 Volkswagen Tiguan

Car has been consuming excessive oil in a short amount of time, Volkswagen claims it’s in “normal” specs but car consumes all the oil after oil change within 1200 miles. Between 0-5,000 miles 2 extra quarts will be added to engine. First time I noticed it was a month after purchasing the car when my oil/engine light came on. Recently oil cap blew off

The contact owns a 2020 Volkswagen Tiguan. The contact stated that the engine warning light was illuminated due to an emissions issue. The message to check the oil level was displayed. The contact pulled over to check the oil and added a quart of oil. The vehicle was consuming an excessive amount of engine oil. The vehicle was taken to an independent mechanic who determined that there was smoke coming from the exhaust. The contact was informed that the cylinder head valve seals had failed and caused oil to seep through the exhaust ports and was burning oil on the second head emissions system and the port was clogged. Additionally, the back over prevention camera was inoperable. The contact determined that the top half of the engine needed to be replaced. The cylinder head was on backorder. The local dealer was not contacted, and the vehicle was not diagnosed or repaired. The vehicle was not under warranty. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

The contact owns a 2020 Volkswagen Tiguan. The contact stated that after adding a quart of oil, the contact became aware that almost every three weeks there was blue smoke coming from the exhaust pipes. The contact stated that the oil warning light was illuminated. The vehicle was taken to an independent mechanic to be diagnosed, and it was determined that the engine was consuming an excessive amount of engine oil. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.

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.

I have been experiencing a noticeable delay in throttle response when accelerating, particularly when attempting to slowly merge into traffic. For example, when I press the accelerator to make a left turn, my Tiguan hesitates for approximately 2-3 seconds before responding, creating a significant safety concern as I find myself stuck in oncoming traffic. I took the vehicle to the dealership for diagnostic testing, but no fault codes were detected, and no warning lights were illuminated. To demonstrate the issue, I had to conduct a test drive with the mechanic. Following this, the mechanic escalated the issue to the quality engineering team at Volkswagen. They acknowledged that they were aware of this problem but stated that there is no available fix. I was advised to use top-tier premium fuel and switch to manual mode to potentially mitigate the delay. When I escalated this issue to the VW Customer Care, they claim that it is operating as designed and no repairs would be made. I suspect that this issue stems from a defect in the vehicle's control software, which VW appears to be aware of but has not addressed with a permanent solution.

I currently reside in Texas where it get HOT during the summer months. I recently got this car back in May. Recently when it’s hot outside my car had cut off one day in traffic and said please check starter system. All electrical components of the car shut off completely. The engine will start run. But the AC, lights, back up camera, windows stop working. I have an appt to drop the car off at the dealership. I been seeing this is an ongoing problem for. VW vehicles I have seen multiple stories about this happening mainly in 2019-2020 jettas. This needs to be an investigation on VW and this problem.
