2023 Volkswagen Tiguan Engine Problems

The contact owns a 2023 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the low oil warning light unexpectedly illuminated. The failure persisted even after the vehicle had received several oil changes. The vehicle was taken to the dealer, but was not diagnosed or repaired. The contact was informed that an oil change was completed; however, the failure persisted. The vehicle was taken back to the dealer where it was diagnosed that the valve stem seal had failed and needed to be replaced. The vehicle was not repaired. The manufacturer was made aware of the failure. The approximate failure mileage was 72,061.

Oil light continues to come on after about 1,000-1,500 miles after an oil change. This has happen several times now and I have to put oil in it to keep it from ruining the engine. I see hat there have been complaints about this already with these models with excessive oil consumption and even engine failure. This needs to be fixed.

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.

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.

Currently in the 22-23 Tiguans they are experiencing an oil consumption issue. Where the engine is consuming oil at a fast rate. I am having to add oil to the car every 800-1000 miles. There’s several class action lawsuits against VW for this exact issue yet they refuse to fix the issue in our car even though it is still under warranty. In writing they told me it’s not consuming ENOUGH oil for VW to approve the repair and that it has to get worse before they will fix it. This problem CAN cause catastrophic failure to the engine. It can also cause the car to stall while driving putting myself and my family at risk. The service advisor admitted that the Tiguans are known oil burners, so much so that they now put in their manuals that burning 1qt of oil per 1000-1200 miles is within spec. It should not be burning oil at all! When I took it to VW bc the check engine light and low oil light was on they said they needed to perform an oil consumption test to see how much it was burning. Yet when I went to pick it up they said that I had to bring it back in exactly 630 miles to do the test. They wouldn’t say why they didn’t get it done that day which I thought was strange. I was unable to get back there at exactly 630 miles bc I work and they are in a different state. So I called to say hey I’m a little Over is that ok. They said no sorry ,we will have to do it at my next oil change. Which per VW is 10,000 miles or 1 year! They want me to wait up until one yr to test this? This is not acceptable! It is costing me money in extra oil every month , putting my family at risk, and putting the car at risk for catastrophic failure . Again, I have the proof in writing where they stated what I said above. As well as receipts and proof that I have taken it to VW for this issue yet they refuse to fix it.

The contact owns a 2023 Volkswagen Tiguan. The contact stated that while driving 35-40 MPH, the engine warning light illuminated. The vehicle was leaking oil. The vehicle was taken to the local dealer, where it was diagnosed that the oil separator, PCV Positive Crankcase Ventilation valve, and gasket needed to be replaced. The vehicle was not repaired. The manufacturer was contacted. who confirmed there was no recall coverage. The approximate failure mileage was 56,000.

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.

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.

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.

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.

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.
