I am filing a safety complaint regarding my 2023 Volkswagen Tiguan SE R-Line with approximately 54,000 miles. The vehicle experienced a significant engine-related failure involving the oil separator/PCV system. Volkswagen diagnosed a failed oil separator/breather that caused excessive crankcase pressure, resulting in substantial oil expulsion and damage/leaks involving the plastic/composite oil pan and timing-chain cover. Volkswagen also identified oil contamination around engine sensors and a P0341 camshaft-position fault. The vehicle has previously experienced EPC/check-engine warnings and entered limp mode, creating concern about potential loss of power while driving. The dealer’s repair required replacement of the oil separator/PCV system, oil pan, timing-chain cover and associated gaskets, along with cleaning oil from the engine compartment and sensors. The repair estimate was approximately $2,490, later reduced to approximately $2,300. Volkswagen declined my request for goodwill assistance. I am concerned that a failure of the oil separator/PCV system can create excessive crankcase pressure and cause oil to be expelled from the engine, damage other engine components, contaminate sensors, trigger fault codes, and potentially result in reduced engine power or limp mode. Sudden oil loss or loss of engine power can create a serious safety hazard, particularly at highway speeds or in traffic. This vehicle has also experienced recurring alignment problems, requiring three alignments in approximately six months, raising additional concerns about the vehicle’s overall reliability and safety. I request that NHTSA investigate whether oil-separator/PCV failures and their resulting oil loss, component damage, sensor faults, and potential loss of power represent a broader safety defect in 2023 Volkswagen Tiguan vehicles.

The car went into limp mode on an Interstate Highway. It was taken to a VW dealer in Mooresville, NC after two other private garages could not diagnose the problem. Their is a current Factory Warranty Extension for 2017, 2018, 2019 VW Tiguan's. The dealer in Mooresville kept the car for two weeks. Drove it for over 100 miles. They claim They can see the code in the computer but it is not active so VW will not pay for the known problem. I feel this is a safety issue as the car will not only possibly go into limp mode at any time but when stepping on the accelerator when not in limp mode the exhibits another known fault. The engine initially sputters as if it is going to stall then accelerates very quickly.

A/C has been a consistent issue since I purchased this from Columbia SC- CarMax's dealership in 2022. I've replaced the compressor and valves, and no resolve. The car sucks up oil and the electrical system is wacky!

I got this car in 2024 and it burns through oil. I am constantly replacing the oil and have had to have the seals replaced a couple of times. Every 200 to 300 miles I have to put oil in it. It’s too new of a car for that. I know a lot of other owners have had issues.
NHTSA complaint #11760563 — an unverified report by a vehicle owner.
I began intermittently noticing a gasoline/fuel odor shortly after taking possession of the vehicle in June 2026. The odor became significantly worse, and I formally reported it to the selling dealership on July 9, 2026. The vehicle was subsequently taken to an authorized Volkswagen dealership for evaluation. A repair order dated July 23, 2026 documents: “Customer states that the vehicle smells of fuel. Could not duplicate customer concern.” Before the evaluation, I explained that the odor becomes most noticeable after the vehicle has been driven for an extended period, particularly in extreme Arizona heat. My normal commute is approximately one hour each way and 60 miles per day. I do not know how far or under what conditions the vehicle was road-tested during the evaluation. The vehicle remained with the dealership during the repair process and was returned to me on August 13, 2026. The condition has continued and has become substantially worse. After extended driving in extreme heat, the gasoline odor can become unbearable and is now noticeable inside the passenger compartment while I am driving. When parked in my home garage, the gasoline odor becomes strong enough to enter the house, and neighbors have also noticed it. The odor has also resulted in complaints from others in the parking garage at my workplace. I’m currently using approximately one tank of gasoline every two and a half days. I do not know whether the fuel consumption and gasoline odor are related. The specific failed component is UNKNOWN. The vehicle remains available for inspection. The concern has previously been presented to both the selling dealership and an authorized Volkswagen dealership, but the cause has not been identified and the condition continues.

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???
NHTSA complaint #11759910 — an unverified report by a vehicle owner.
My 2022 Volkswagen Tiguan has an ongoing excessive oil consumption problem that began in April 2025 when the low oil warning illuminated. I added approximately one quart of oil and contacted the Volkswagen dealership. The dealership instructed me not to add oil myself if the warning returned and to bring the vehicle in for evaluation. On May 12, 2025, I brought the vehicle to the Volkswagen dealership and an oil consumption test was performed. The problem continued. I returned the vehicle on July 25, 2025, and a second oil consumption test was performed. The dealership subsequently replaced the PCV valve in the engine in an attempt to correct the oil consumption problem. On August 25, 2026, the check oil warning illuminated again, indicating that the problem has continued despite two oil consumption tests and replacement of the PCV valve. The dealership is now requesting that I bring the vehicle back for a third oil consumption test. The vehicle has repeatedly been made available to the Volkswagen dealership for inspection and repair. Each time it is taken in for this problem, the dealership keeps the vehicle for approximately one week, and there has been little communication regarding the status of the vehicle unless I contact the dealership myself. I am concerned that the underlying cause of the excessive oil consumption remains unresolved despite repeated testing and an attempted repair. I am concerned about continued oil loss, potential engine damage or engine failure, and the safety of operating the vehicle while the cause of the oil consumption remains unresolved. The vehicle is available for further inspection.

What component or system failed or malfunctioned, and is it available for inspection upon request? During a multipoint inspection that was earlier than advised due to multiple dashboard lights engaging, we were told that our car has an oil leak due from the timing covers and lower pan seal. They removed the oil separator and found value stem seals to be out towards the exhaust side creating an oil leak that stemmed from blown timing covers and the lower oil pan seal being the cause of the leak. The oil separator was noted as failed. This car has been brought in for every inspection and continued to have lights on post inspection that we were told regularly that they forgot just to turn off the lights but that the oil had been changed. In fact, our next oil change wasn't due until February 2027. How was your safety or the safety of others put at risk? Our safety has been put at risk driving a car with a substantial oil leak and faulty components that only seem found after we are 8,000 over the warranty. In searching the internet, this oil valve and leak situation is common in 2022 Tiguans enough so that there are multiple threads and articles about it. Has the problem been reproduced or confirmed by a dealer or independent service center? The dealer confirmed that this is an ongoing issue with these cars and that Volkwagen may be looking into doing a rebate for repairs. That doesn't fix the issue with the safety of the vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? We will be checking in with our insurance provider as well as an independent service center after dealing with Heritage Volkswagen Group due to our warranty. That warranty obviously provided us nothing for its cost or coverage. The lights were present and always brought in to be checked at the dealer we bought the car from. Again, we were always told that the lights didn't mean anything and they were left on after service accidentally
NHTSA complaint #11756299 — an unverified report by a vehicle owner.
My 2014 Tiguan, VIN [XXX], has been serviced at an authorized VW dealer since I purchased it. From 2014 to December 2025, the vehicle was serviced at a VW dealer and March 2026 to present at a service facility that only works on VWs and is owned and operated by a prior VW certified technician who only works on VWs. My vehicle has been serviced at all the VW recommended maintenance mileage. Looking back at the maintenance records, I can see that in March and August 2025, my vehicle experienced a check engine light issue that resulted in EVAP system small leak fault and vibration at start up caused by misfire cylinder. In April 2026, June 2026 and July 2026, I had to take my Tiguan in because I felt the engine shake, check engine light came on and power decrease. The VW technican replaced some components related to the turbocharger system in April and the check engine light turned off. The check engine light turned back on in June in June and July 2026. The technician stated the issue was likely a airflow flap within the turbocharger causing the issue and the entire turbocharger would have to be replaced to remedy the issue. I discovered the recent class action settlement on this same issue and shared it with my mechanic. His professional opinion was that the issues I was having were exactly what was covered in the settlement covering my vehicle but i had 94k miles and had to have less than 85k miles. So, I was not covered because of the mileage. But I believe the issues the vehicle had going back to March 2025, were all turbocharger issues. In any case, my mechanic reached out to VW to get assistance because of the mounting repair costs for me and for all of his other VW owners experiencing turbocharger defects. It is my hope that others have shared similar complaints in search of relief from NHTSA investigating the defective VW turbocharges. VW has a negative track record on it's turbochargers.

I'm filing an urgent safety complaint regarding a series of severe defects in my 2026 Volkswagen Tiguan (VIN: [XXX]) that pose immediate, life-threatening hazards. On XXX, I took delivery of the vehicle, which was refueled by the dealership. By XXX, with temperatures soaring to 104°F, I encountered three critical issues: 1. **Engine Stall During Low-Speed Turn**: While turning at 2 MPH, the engine shut off without warning, losing power steering and brakes, and displaying a message to "manually restart the engine." 2. **Engine Stall While Reversing**: The engine stalled again while reversing into a parking spot, triggering the same emergency warning. 3. **Structural Window Seal Failure**: At 55 MPH, the driver-side window seal tore away, becoming a projectile that struck the passenger-side window, creating a severe distraction and road hazard. Despite reporting the engine stalling issues to the dealership, the service manager didn’t open a formal Repair Order, citing the stalling as "intermittent." On July 5, while attempting to refuel with half a tank, gasoline violently sprayed from the rear undercarriage, indicating a catastrophic failure of the fuel tank venting system. These incidents within 72 hours of delivery highlight systemic manufacturing and quality control failures. I have had the car towed back to the dealership via flatbed tow and the Volkswagen roadside assistance representative assisted with this transaction. I urge the NHTSA to investigate the fuel tank venting mechanisms, engine management software, and exterior seals of the 2026 Volkswagen Tiguan. Immediate action is necessary to quarantine this VIN ([XXX]) and assess potential safety recalls or stop-sales.

I was driving in 4 lane town traffic going under 10 MPH and the hazard lights came on by themselves, and the car died. Propulsion stopped. Fortunately I was able to pull onto a striped median, and once I was over shock, 3-5 ish minutes, I started the car and drove to the dealership. I don’t remember any warning message, and it seems like the steering and brakes were hard once it was dieing, but I was so shocked it’s hard to remember exactly. This happened in rainy weather, about 65 degrees around [XXX] on [XXX], in Bentonville, AR. INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

Our vehicle does not respond to the throttle pedal being depressed when the AC has been turned on at full and the car has been in direct sunlight for a period of time. We reside in Florida so it is common to enter the vehicle during the summer months and the cabin temperatue is in excess of 200 degrees which requires putting the AC system on MAX. This problem occurs periodically and was address in the summer of 2025 at the VW dealership locally

First purchased this car from a dealership in 2023, used at128,051 miles. Did not have any problems with it in the first year I would say. Then suddenly while driving down the road the epc light would come on limiting my speed to 4,000 rpm. It would come on and off also causing my check engine light to come on and off. It has now become more frequent, the epc and check engine lights will come on and off creating a major hazard while driving. Got it scanned while the check engine light was on and it ran a code for a cylinder 4 engine misfire from my fuel injector wiring rail harness. It looks to be a common problem with this model but it’s showing my vin is not attached to a recall.
NHTSA complaint #11733032 — an unverified report by a vehicle owner.
2018 VW Tiguan. The fuel injector harness failed. There is a NHTSA letter stating 2018-2019 Tiguans had this issue and there’s an extended warranty up to 120,000 miles. My Tiguan is at 91,000 miles, but VW is saying the warranty isn’t assigned to my VIN. So there’s a warranty for this exact issue and year, but my vehicle isn’t covered. This warranty obviously needs to be extended by build date as it’s a pretty costly repair.

I am filing this complaint to seek a full buyback and debt cancellation for a 2017 VW Tiguan (VIN: [XXX] ) sold to me by Carvana for $40,000. Summary of Deception: Carvana sold this vehicle as "Certified" with a "150-Point Inspection" guarantee. This was a fraudulent misrepresentation. Within six months, the vehicle required 45+ mechanical services, including a full internal teardown that revealed catastrophic wiring corrosion caused by a long-term sunroof leak. These were latent defects present at the time of sale. The vehicle has has 2 Turbos: one recalled (now currently being recalled again) and one replaced 3 months into ownership. The vehicle slowed down on [XXX] traffic and I had to make an emergency exit and take to the dealership. This make and model were completely overhauled engine and externally after my model 2017. 45 mechanical services in 12 months justifies a recall and an exchange, Safety & Financial Hardship: As a high-level executive commuting from [XXX] to [XXX] , I required a reliable vehicle. Instead, this car decelerated dangerously on [XXX] , nearly causing a collision. Despite active steering and turbo recalls, Volkswagen mechanics have deemed the car "unsafe for road use" since January 2025. I am warned that any further driving will void my warranties due to engine damage risk. Bad Faith Negotiations: I have attempted to resolve this with Carvana and Volkswagen Executive Care. Carvana offered a mocking $500 gesture for a $40k total loss, while their supervisors were condescending and dismissive. They have refused to provide the original inspection report. Impact: I have lost tens of thousands in wages, rental costs, and storage fees while my credit and mental health suffer under $19,000 of debt for a "shell. " I am seeking an immediate buyback at their expense to resolve this matter and restore my ability to work safely.

NHTSA complaint #11729125 — an unverified report by a vehicle owner.
I am filing this complaint because my Volkswagen Tiguan has a serious and ongoing engine issue involving excessive oil consumption and a faulty cylinder head. The vehicle burns through an abnormal amount of oil between changes, requiring constant top‑offs, sometimes as frequently as every few hundred miles. Despite regularly adding oil and following all manufacturer‑recommended maintenance, the issue continues to worsen. The dealership has confirmed that the cylinder head is defective, which is causing the engine to consume oil at an extremely accelerated rate. However, I have been told the replacement cylinder head is on national backorder, and there is currently no estimated timeframe for when the part will be available. This means I am forced to continue driving a vehicle with a known, documented engine defect that can: Lead to engine stalling Create loss of power while driving Increase the risk of engine seizure Potentially cause a safety hazard on the road Additionally, being required to constantly add oil just to keep the vehicle operable is not only unsafe but financially unreasonable. The problem remains unresolved despite multiple service visits, documentation, and repeated oil consumption tests. This is a safety issue, not just a maintenance concern, because the engine can fail unexpectedly if the oil drops too quickly. I believe this is a significant defect affecting multiple Volkswagen vehicles and should be investigated by NHTSA. I request that NHTSA open a formal investigation into the excessive oil consumption and cylinder head defects on Volkswagen Tiguans, as owners should not be left with unsafe vehicles due to known manufacturing issues and unavailable critical engine components.
