2021 Volkswagen Tiguan Complaints

ENGINE,FUEL/PROPULSION SYSTEM — Filed 10/19/2023

The high pressure fuel pump has failed within 40,000 miles and now again at 110,000 miles. It causes the vehicle to randomly turn in drive and while idle. It has had oil consumption issues and oil leak issues that constantly occur. The dealer has replaced the high pressure fuel pump under warranty 40,000 miles and has now detected it needs to be replaced again at 110,000 miles. I paid for oil leak repair which was over 5,000 dollars and now I have another oil leak issues with the oil separator.

At 58,218 miles, the engine on this 2021 Volkswagen Tiguan failed after excessive oil consumption progressed to engine knocking. The vehicle was brought to Volkswagen of Orange Park on July 24, 2025, for excessive oil consumption. The dealer performed a second oil-consumption test. During the test, the engine was heard knocking. The dealer removed the oil pan and found excessive metal. Volkswagen replaced the engine under warranty. The repair invoice was dated August 31, 2025. This created a safety concern because an engine failure can cause loss of propulsion or stalling while driving. The dealer confirmed and repaired the condition.

At approximately 53,876 miles, my 2021 Volkswagen Tiguan experienced a severe, premature failure of the Positive Crankcase Ventilation (PCV) valve / oil separator assembly. The failure of this component caused an immediate, dangerous buildup of internal crankcase over-pressurization. Because the excess pressure could not vent safely, it caused a catastrophic domino effect through the engine block, structurally blowing out multiple critical engine gaskets and rubber oil seals. Furthermore, the extreme downward pressure physically cracked the factory-installed composite plastic oil pan, leading to an immediate and rapid engine oil leak. A sudden and rapid loss of engine oil and internal oil pressure while operating a vehicle at highway speeds poses an extreme safety hazard. Had the oil pressure dropped completely while driving with my children in the vehicle, it could have resulted in a sudden engine seizure, sudden loss of motive power, or complete engine failure on a live highway, placing my family and surrounding drivers in imminent danger of a high-speed collision. Volkswagen is aware of this engine design defect, as evidenced by active internal Technical Service Bulletins (TSBs) and a pending federal class-action lawsuit (Reece v. Volkswagen Group of America, Inc.) detailing identical PCV-induced seal and plastic oil pan failures in the exact same model year. Volkswagen's failure to issue a safety recall for this unlisted "lifetime" part forces families to drive under the threat of sudden component blowout and subsequent engine failure. A mandatory safety investigation and recall are required to address this systemic powertrain defect.

2021 Tiguan parking brake comes on without being commanded. There is a fault with the drivers door. I believe the the driver door module or corresponding wiring. The front drivers window toggle switch does not work the toggles switches for the rest of the window work only if the is not an error displayed on the dash. The lock button does not work on the drivers door at all and only works on the rest of the door when an error message is not displayed on the dash. The dash displays the following errors: 1. Driver Door Contact Switch. 2. Start/Stop. 3. Electronic Parking Brake. It also displays Attention: Engine is running. So far the parking brake only comes on(un commanded) when the vehicle is stopped.

Like many others, at 55k miles, our oil separator malfunctioned causing our oil pan to crack and dump every drop of oil. We had to replace the oil pan and fortunately our mechanic friend figured out it was the new pcv valve malfunction causing too much pressure in the engine. My wife was luckily pulling onto our property when the car essentially shut itself off. When searching for the valve I needed, talking to multiple parts dealers and then a vw tech, none of them are sure why there’s no recall. It happens between 50-60k to THOUSANDS of people now. Then I watched videos on the issue and the mechanics online are all saying the same thing- this should’ve been a recall 2 years ago and are all asking the same question. It’s time VW does what’s right. It’s awfully coincidental that they installed plastic oil pans that would crack and leak under instead pressure, rather than a blowout seals because of the valve failure.

Taking left turns is dangerous. My turn very slowly and Hard press on pedal to turn. Oil consumption is insane. Started at 38k miles, manufacture warranty ended after 4 years. I’m under 52k miles now and have to fill oil about every 1k miles. I’ve had 4 oil changes this year alone. I’m regular about Maintenence. Last oil change was 08/03/26 check oil light came on 8/15 had to add 3.5 quarts 8/26/26 Will keep track of each time I need to add oil and update here. This has been an issue for many Tiguan owners where is the recall???

Noticed the check engine oil light started coming on periodically between oil changes 3-4 years ago, but no external or noticeable oil leaks. Was told by VW multiple times it’s standard for VWs to burn oil. I started having to top off oil much more frequently over the last year, 1 quart per 1000 miles. The check engine oil light would turn on every month at random times while driving. Took my car to a shop; they removed 02 Sensor 1 and borescoped the exhaust system. Found oil leaks from valve seals, leaking into the exhaust manifold. A few weeks later, the check engine light came on for the first time (codes: P24D6 and U3501). Brought car to another shop; they scanned the car and the following codes were found: U350100 (Passive/Sporadic) - Control Module Input Power "A" Circuit Low U041600 (Passive/Sporatic) - Invalid data received from vehicle dynamics control module) P003000 (Passive/Sporatic) - O2 Sensor Heater Control Circuit Bank 1 Sensor 1 U105400 (Passive/Sporadic) - Information electronics 1 control unit No communication P24D600 (Passive/Sporadic) - Evaporative Emission (EVAP) system pressure sensor/switch B circuit range performance. The second shop also stated the valve stem seals needed to be replaced in addition to the Upstream Oxygen sensor and PCV valve. The car was brought to Volkswagen for repair under the extended warranty. Volkswagen confirmed the PCV valve and valve stem seals were bad and needed to be replaced. VW also noted smoke coming from the exhaust. The vehicle has 53k miles on it.

PCV value/oil leak is a known issue with this specific model of car. The repair I was quited was over $2700 when the car is just out of warranty. There was no oil light indication showing that the oil was low! I only checked everything out because I saw oil in the drive way. The car read zero oil on the dip stick. I added 4 quarts and finallt started to get into operating range. My wife drives this car and could have been in a major accident if it hadn't been noticed.

ELECTRICAL SYSTEM,ENGINE,FORWARD COLLISION AVOIDANCE — Filed 07/29/2026

My name is [XXX], and I am writing today to express my complete frustration mentally and financially with a CPO 2021 Volkswagen Tiguan (VIN [XXX]) I purchased XXX. To date my vehicle has been in for service multiple times – countless times for an issue with the infotainment system and driver warning indicators that is still unresolved and again for months waiting on a new engine due to an oil consumption issue that was finally resolved November of 2025 (Case XXX). My recent service visit on XXX was due to a “12 v battery not charging” error message. The vehicle was immediately taken to VW of [XXX] where we were advised it would be 3 weeks before my vehicle would even be looked at (which is atrocious) and not to drive it because further damage would be caused with no alternative solution offered for transportation. I then had the vehicle towed to a repair shop where I was advised the alternator “fried a 400-amp fuse and killed the battery, which should not happen, especially on a vehicle that has less than 50,000 miles on the odometer.” I paid $1,605.37 for a new alternator, 400-amp fuse and battery. Completely appalling and disappointing considering I take excellent care of my vehicle and it is supposedly an inspected, certified pre-owned vehicle – that’s a lemon in my opinion! I am seeking reimbursement for this huge expense for a vehicle that should not have these issues! I look forward to a resolve to this urgent complaint.

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.

On ~August 1, 2022, the "overheard console" (containing lights, BT microphone, and sunglass compartment) unexpectedly "dropped" out of the vehicle's ceiling. The plastic and adhesive keeping this part in place appeared to have cracked into pieces, and the weight of the part caused it to fall. I was driving during this incident and it startled me into nearly having an accident. When I called the dealership I purchased this brand new car from less than two years ago, (Hewlett Volkswagen of Georgetown, Texas) they informed me that I was one of MANY customers experiencing the same issue on Tiguans manufactured in the last 2 years. In fact, when I described what happened, the service advisor guessed my make/model before I provided further detail. The dealership refused to accommodate my safety (let along the inconvenience) by offering a tow/loaner vehicle, so I had to drive over 25 miles (~40 minutes) to bring the car in to get the broken console removed. In that trip, I almost got into another accident because the part dangling from my ceiling was obstructing my view while driving. I have been waiting 6 weeks to get this part replaced, which the dealership confirmed was back order issues because they've had so many instances with other VW Tiguans this summer. I have contacted VW Customer Service hotline AND the dealership about a recall on this, but both validated that they've never filed anything despite being fully aware that "dropping overhead consoles" have been a RECURRING safety risk for cars with my make/model/year for months. While I've waited for VW to take responsibility, I've injured myself getting into my vehicle at night because I have no lights inside the car, let alone at extreme risk for assault. And because I cannot use the BT microphone, a feature which encouraged me to buy this car brand new, I have had to make sacrifices in my career. My life and the lives of others have been put at risk because VW has refused to consider this a safety recall.
