2023 VOLKSWAGEN TIGUAN Engine Problems

I am submitting this report to express serious concerns regarding my 2023 Volkswagen Tiguan, currently under a lease agreement and serviced exclusively at South Motors Volkswagen in Miami, Florida. The vehicle was originally delivered as a loaner with approximately 1,000 miles and now has 24,000 miles. Since early in the lease, the car has repeatedly displayed low oil warnings, despite being serviced multiple times under 10,000 miles. During my most recent service visit in June 2025, I was charged $9.48 for a minor oil top-off. When I contacted the service advisor afterward, I was advised to purchase 1-OW20 oil myself and manually add it whenever the warning appears, until the next 10,000-mile service interval. Following that advice, I have now purchased two bottles of oil out of pocket—the first cost $12, and the second $42—just to keep the vehicle running between service visits. This additional expense reinforces my concern about excessive oil consumption in a relatively new vehicle and may indicate a mechanical defect. Additionally, the brakes emit a persistent squealing noise, even though the dealership claims the brake pads are at 50% life. The noise affects driving confidence and may signal premature wear or improper installation. Despite these ongoing issues, no repairs have ever been performed under warranty. Each time I’ve taken the vehicle to Volkswagen service, I’ve been told that everything is functioning perfectly and that there is no problem to address. This repeated dismissal of the symptoms is concerning and leaves me without a clear resolution. My lease is scheduled to end in September 2026, but due to the unresolved mechanical concerns and the lack of meaningful support from the dealership, I would like Volkswagen to consider terminating the lease early. This would allow me to obtain a vehicle that does not present these recurring issues and restore my confidence in the brand’s commitment to safety and reliability.

I own a 2023 Volkswagen Tiguan (EA888 2.0L). The Check Engine Light has repeatedly illuminated, and multiple scans show recurring EVAP/emissions and network communication faults: P04F0 (EVAP purge line A performance) and P0451 (fuel tank pressure sensor range/performance), along with U1111 00 (“function limitation due to missing message”) and U1123 00 (“databus error value received”). While drivability may seem normal at times, these faults persist and clear/recur, raising concerns about fuel-vapor containment/emissions compliance and potential intermittent loss or limitation of vehicle electronic systems/driver-assistance functions due to CAN-bus communication errors. I’m reporting this because the condition is ongoing, produces a continual CEL, and may present safety and reliability risks if not addressed by the manufacturer.

The contact's granddaughter owns a 2023 Volkswagen Tiguan. The contact stated that while her granddaughter was driving at an undisclosed speed, the low oil pressure warning light illuminated. The vehicle was driven to the residence, where oil was added to the vehicle. The vehicle was then taken to the dealer, where an oil change was performed. Additionally, the dealer replaced the oil separator and gasket. The vehicle was repaired. The manufacturer was notified of the failure and informed the contact that the repair could not be covered because the vehicle was out of warranty and the previous oil changes were not performed by the dealer. The failure mileage was approximately 66,000.

Mileage: 66,000

I am experiencing a high oil consumption rate on my 2023 VW Tiguan. VW claims that the rate of consumption is within the 1 Quart every 1200 miles limit, but 3500 miles after an oil change, the check engine oil light came on and I had to add oil. 2000 miles later, it came on again and I had to add oil again. In a 10,000 mile oil change rated car, this would equate to adding 8-9 quarts of oil between changes. This is not normal oil consumption. The effects of increased emissions and premature fouling of the catalytic converter system alone is cause for concern, or the possible loss of engine power on the highway due to failure from lubrication loss, resulting in an accident. The car will emit blue/white smoke from tailpipe and rough idle randomly when the cylinders are overloaded with oil.

Extreme oil consumption would cause a catastrophic engine failure. Low oil warning light going off (3 times within 3000 miles) requiring the need to add oil. Oil on dipstick is down to the bottom. Had local Big O check it out - oil had been lost. Currently doing a 1000 mile oil consumption test through dealer. Started at around 48,000 miles. Currently have 52,000.

The vehicle experiences intermittent (but daily) accelerator lag or failure to respond when the gas pedal is pressed from a stop. There is a significant delay—sometimes several seconds—before the car begins to move, even when the accelerator is fully depressed. This appears to be related to the power train and/or engine system. The hesitation in acceleration has created multiple unsafe situations, including near-miss accidents while turning left across traffic or entering intersections, when the car failed to respond as expected. This hesitation could easily result in a collision, particularly in high-traffic areas. The issue has been reported to the dealership on multiple occasions and while they have been able to reproduce the problem, it isn't every time and they turn the vehicle back over to us unresolved. Video documentation of the malfunction has been submitted to the service department, and they have acknowledged the issue is being reviewed by VW engineers. The vehicle has been inspected multiple times by the authorized Volkswagen dealership service department. Engineers from the manufacturer have reportedly been involved in the review, though we have not yet received a confirmed diagnosis. There are no warning lamps, dashboard messages, or error indicators associated with the accelerator issue. The first noticeable delay in acceleration from a stop occurred at least 6 months ago and has continued intermittently since.

The oil level light has come on 4 times. The car has under 20,000 miles on it. This puts my safety and others' safety at risk as low oil can cause the engine to stop working rendering the car dangerous if the oil becomes too low while driving. This is a known problem with VW Tiguan's and there is a current lawsuit regarding their oil consumption. The dealer has topped off the oil when needed. The oil light comes on and is typically a quart or more low when checked.

Vw tiguan 2023 consume a lot of engine oil every 2000 and 3000 mile the oil engine light turn on and it shows that oil level is low and that 2nd time happens since I bought the car in 01/2023 the service manager in vw las vegas sahara told me that normal every 3000 mile you have to add oil I told him that new car not 20 years old car so he told me that how it is can you please investigate the issue now I scare to drive far and there is a lot complain online about the issue thank you

VW Dealership in West Lebanon NH is acknowledging that there is an issue with VW Tiguan engines burning oil at a higher rate than the standard. The fuel low indicator keeps coming on. They advise me to add oil which is coming out of my pocket vs theirs under warranty. I've had two appointments. They are now doing a fuel consumption test and I have to return for a 3rd appointment. They stated they are seeing a lot more folks like myself coming in with lower mile Tiguan with this issue. Normally they are seeing many with 50K + miles. While I was there another customer overheard the service adviser talking to me and he said he has the same issue. Blue puffs of smoke coming out of the back too when we start car. Seems like this is a huge issue that is now coming to light. Dealership told me i'm at a stage 2 with VW and next steps is taking engine apart and warning VW of issue.

From a cold start, the vehicle seems to have an issue with fuel/acceleration. When pressing the gas through an intersection, the vehicle seems starved for gas and does not accelerate and almost stalls. This is very dangerous in a city environment, as the gaps between cars is sometimes small. There are no warning signs, just reports from several of my drivers experiencing the same issue with the same vehicle. We just purchased 13 of the same vehicle.

The vehical when engine is cold. Has delays and lags. I didn't think much of it when I first bought it, I assumed the computer was trying to learn. Well car has 12000 miles on it and still does it I've been to the dealer several times. They have told me this is normal?. Until I went to a different dealer. Service Manger states the vehical has a software problem and none repairable at the time ( I have paperwork to prove it) I tried to lemon the car out after that. Vw state because the info wasn't written by a service tec, they won't lemon the car out? I fear my wife getting t boned.

When I click the button to start the car and then quickly reverse, the system locks up. It's a safety hazard. It's happened to me 4 times. Twice on 7-14-23 and another two times within the last 3 weeks.
