2021 Volkswagen Tiguan

My Tiguan leaks and burns oil like crazy. Now it has 111k miles on it, but this has been an ongoing issue for the last five years since I've had it. I now have to put a quart of oil in every 100 miles. This is not the fault of me getting an oil change, this is a persistent problem caused by the manufacturing of the car. I have had the engine nearly seize up while driving on the freeway due to low oil from this issue. Please investigate and fix.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving downhill at an undisclosed speed, the vehicle lost automotive power. The vehicle was coasted into a driveway and restarted. Upon restarting the vehicle, the electronic power control (EPC) warning light and the yellow triangle for the central warning light illuminated. The vehicle was idling roughly and jerking while driving to the dealer. The vehicle was previously serviced at 50,500 miles due to an EPC fault, and dealer replaced an electronic actuator. Additionally, the battery was replaced at 50,500 miles, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 51,960.

The PCV valve does not last past 60k miles. Multiple forums and customers stating this. When the failure shows up as a check engine light symptom it has already caused a major oil leak in the crank shaft that leaks with the car off at about 500ml and is significantly worse while driving- Up to a quart of oil loss from driving 10miles. VW has had issues with the PCv valve design from 2012. I bought a 2012 Passat but it did not leak till well after 200k miles but the code would continuously go on and off.

approximately 1 year after purchase, we started having the oil light come on. Returned to dealer and they stated it was normal. This continued for approximately 4 or 5 more times. A "comprehensive" test/diagnostic was conducted and they said normal consumption but no issues. Moving now in 2026 with 40k and now out of warranty with age of vehicle, we brought it back to Scott Motors and NOW it's an issue with the head. The same common problem that they have known about with all their vehicles in this class with this motor since I believe 2018. They want to split the repair bill 50/50 and then 70/30. I stated I addressed and documented the issue years ago and now since we are out of warranty, now you find it. Please Help.

My 2021 Volkswagen Tiguan is experiencing excessive engine oil consumption. The oil level drops rapidly between oil changes, and I have had to add oil multiple times to prevent engine damage. The low oil warning light has appeared unexpectedly while driving, creating a safety hazard. I am concerned about potential engine failure, stalling, or loss of power at highway speeds. I have reviewed multiple NHTSA complaints from other 2021 Tiguan owners (IDs 11742786, 11741539, 11741067, 11739933) reporting the same oil consumption and low oil pressure issues. This indicates a pattern of defects involving the EA888 2.0 TSI engine. Volkswagen dealerships often claim this is ‘normal,’ but the frequency and severity of oil loss suggest a mechanical defect involving piston rings, PCV system, or internal engine components. This poses a serious safety risk, especially during long distance travel. I am requesting that NHTSA investigate this issue for the 2021 Tiguan model year.

The component that is failing is the Radio. The radio consistently turns off when using it and power cycles itself back on which creates a concern when I am using the phone or the Maps feature. I had the same issue with a 2019 Volkswagen Passat, that I previously owned and I now see that there are known issues with other Volkswagen vehicles for the same thing, but there is no recall on my vehicle. I have spoken to my dealership about it and they advised me that there is not a recall for the issue so I would have to pay for them to take a look at this. There are no warnings such as lamps or anything else prior to the failure happening besides if the radio has sound coming through it, you won’t hear the sound anymore and within 60 seconds it will power cycle down for about a minute and then come back on and have to completely reload. There has been no inspection by the police or manufacturer to my knowledge.

On 03/11/26 Volkswagen pushed an over the air update related for an infotainment System Software Update. Immediately upon completion of the updated the Central caution light (exclamation mark inside of a triangle) was illuminated along with the SOS warning light. This has caused by SOS safety system to not function properly. The dealer charged me $200 to diagnosis a problem VW created and stated the SOS Control Module needs to be replaced. They claim the part is on National back order for the past three months. I have been unsuccessful receiving information regarding the repair of my vehicle. I am concerned the SOS system will not function if it is needed.

Rear view mirror has come detached from the main roof and it's presented that the only option to repair this is a complete windshield replacement. If the mirror is adhered to the windshield, this presents a major design flaw and safety hazard. I should not have to replace an entire windshield to replace just a rearview mirror. Also, because this is requiring me to seek additional services outside of the VW dealership, I would have to drive without a safely secured rear view mirror, presenting a safety hazard.
