2021 Volkswagen Tiguan Engine Problems

Your 2021 Tiguan is consuming and leaking oil at a dangerous rate — the low oil warning light comes on weekly, and you've had to add oil frequently to prevent engine damage. You've noticed oil pooling underneath the vehicle, and the problem appears to be caused by a failed PCV (positive crankshaft ventilation) system that has ruptured multiple oil seals. If the engine loses oil pressure while driving, it could suddenly lose power and control, creating a serious safety risk. The fix will likely involve replacing the PCV system, oil seals, and possibly the oil pan and crankshaft seal.

Your 2021 Tiguan's engine has suffered internal damage from metal objects that got into the engine, requiring a complete engine replacement at around 70,000 miles. The dealership found impact damage to the engine's rotating assembly consistent with foreign object intrusion. This repair will involve removing and replacing the entire engine, which is a major undertaking.

Your 2021 Tiguan experienced a complete engine failure at 40,000 miles after multiple warranty visits for engine problems that the dealership said were normal, including excessive oil consumption, coolant warnings, and power loss. The engine failed suddenly while driving, making the vehicle inoperable and creating a safety risk since power loss while driving could cause a crash. Volkswagen is now denying warranty coverage even though these same issues were documented during the warranty period. Resolving this will likely require Volkswagen to investigate the engine failure, review service records, and potentially replace or rebuild the engine under warranty coverage despite the mileage.

Your 2021 Volkswagen Tiguan's engine failed completely at only 46,000 miles, even though the vehicle was properly maintained and well under typical mileage limits. Volkswagen denied warranty coverage because the vehicle is just past its 4-year warranty period, leaving you responsible for a costly engine replacement. The repair will likely involve a complete engine replacement or rebuild.

Your engine is losing oil quickly — needing a quart every 2 days after dealership oil changes — and occasionally blows smoke from the rear while showing sluggish performance. The dealership confirmed a faulty PCV valve is causing excessive pressure buildup in your engine, which damaged the oil pan gasket and is leaking oil underneath your vehicle. This repair typically costs $1,000–$8,000+ and may require extensive engine work to fully assess the damage.

Your check engine light came on, and a VW dealer diagnosed that your car needs a new cylinder head. However, the dealer didn't tell you that this part is on nationwide backorder with no estimated arrival date, leaving your car unable to be repaired. You're concerned that Volkswagen hasn't provided a timeline for fixing these cars, and you believe this delay may qualify your vehicle under lemon law protections.

Your oil pan cracked and leaked oil onto the road, causing your check engine and PCV warning lights to come on. After the first repair, the same problem happened again—the mechanic discovered the real issue was a failed or clogged PCV valve, which is a known problem in your model at around 93,000 miles. The dealer warned that this failure might happen again even after repair, and there's currently no recall for it.

Your check engine light came on and you noticed excessive oil leaking from the engine. The dealer found that your PCV/oil separator failed, multiple valve stem seals failed, and valve stem guides are worn out, causing too much pressure to build up in the crankcase. Your car needs a cylinder head replacement, but the dealer has had it for a month waiting for the part to arrive with no clear timeline for when it will be ready.

Your check engine light came on while driving at 55 MPH, and you later noticed oil pooling under your parked vehicle on multiple occasions. A dealer diagnosed a breather system failure that allowed pressure to build up in the engine, damaging the upper timing gasket and seal and causing an oil leak. The repair involved replacing the oil separator timing cover, CAM magnets, and oil pan.

Your 2021 Tiguan experienced a failed PCV valve that caused excessive pressure in the engine, cracking the plastic oil pan and timing cover. This led to a significant oil leak, and while driving on the highway, your engine warning light came on with a message limiting engine speed to 3,000 RPM, causing the vehicle to become sluggish and difficult to keep up with traffic. The dealer confirmed the cracked oil pan and timing cover leak through visual inspection and error codes. Fixing this issue will require replacing the PCV valve, the cracked oil pan, and resealing the timing cover.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving at an undisclosed speed, the contact noticed blue smoke coming out of the exhaust pipe. There was no warning light illuminated. Additionally, the contact stated that the vehicle was experiencing excessive oil consumption. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was not made aware of the failure. The failure mileage was approximately 46,000.

At only 38,200 miles the dealership found shards of metal in my engine. The only solution is to replace the entire engine and my car just passed its warranty 5 months ago. I have kept up to date with services and driven the car responsibly. There is also another 2021 VW Tiguan owner in my town and her car did the same thing at only 29,000 miles! She was still under warranty so the engine was replaced but she now states that it burns through oil at a concerning rate. One day the engine like just turned on, then the car goes into a “limp” mode and doesn’t exceed 3000RPM.

At about 60,000 miles a VW dealer told me it was normal for VWs to use oil. Now at 80,000 I have a $2,000+ bill b/c the PCV is faulty and the timing cover has failed. I did NOT get a low dngine oil warning, but mechanic says panic wait it was low ( oil change 4,000 miles ago). This could have led to a seized engine on the interstate. I am upset to learn this is a common problem with this vehicle. It is an expensive repair. From other posters I fear this is not the end of the problem. VW should recall this part .

The lower oil pan cracked due to excess pressure in the engine from a broken oil air vent. This is a very common issue in VW tiquans, that VW knows about but doesn't recall. The faulty air oil vent leads to cracked lower oil pans and oil dumps that can damgae the engine and creates dangerous driving situations.

volkswagen vehicles have a real serious problem that can cause your car fails in the middle of the road, and it is the oil separator. A failing oil separator can lead to poor engine performance and potential damage. It will cause a massive oil leak that will damage others' engine components, and the car can stop working at any moment, and it can be a dangerous situation. The most affected vehicles are Volkswagen tiguan. Please investigate this problem because a lot of people are dealing with this dangerous situation.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving 65 MPH, the accelerator pedal was depressed, and the vehicle failed to respond. The contact stated that the vehicle was losing power and was unable to drive uphill. The contact also stated the engine was consuming an excessive amount of oil; however, the dealer had informed her that the oil consumption was normal. The check engine and electronic power control (EPC) warning lights were illuminated. The vehicle was taken to a dealer where it was diagnosed and determined that the turbo cylinder and timing chain needed to be replaced. The local dealer was contacted; however, the vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 200,000.

My 2021 Tiguan suddenly lost power causing my wife and daughter to be stranded. Car was not drivable and lost both oil and power. Towed to VW dealer and was diagnosed with a faulty pcv/oil separator causing excessive crankcase pressure. This party failed once car warranty was over costing almost $2000. Prior to the car stranding them they had to drive at less than 25 MPH on the Long Island expressway. oil was leaking from the upper timing cover seals. VW Dealer removed and replaced oil pan with gasket, pov and upper timing cover seals. filled o i l to correct level,road tested vehicle and rechecked and no leaks at this time. All this damage occurred by no fault of our own. I have learned thru my research that this is a common problem on the VW Tiguans. All has been repaired and replaced as you can see from the receipt attached. Prior to the party failing multiple lights lit up on the dashboard forcing my wife to pull over and get out of. harms way until someone could come and get her.

There was an issue with excessive oil consumption. In as little time as I have owned this vehicle I have had to top my oil off between oil changes because my low oil light had came on. I then, over the winter got a check engine light, it threw code P24D6 which pertained to the oil leak and/or seperating. I then noticed that on my driveway, I have some oil from my car. I paid a mechanic $200 to fix this plastic drain that according to the mechanic doesnt reseal.

Pcv valve on my car went and caused seals to leak in my engine. This has caused oil to leak onto my exhaust system which poses a fire hazard according to the dealership. Car should not be driven. Many many complaints about this issue of the PCV valve failing have been discovered online. Worried about my car catching fire if I drive it

The contact owns a 2021 Volkswagen Tiguan. The contact stated that the vehicle was leaking oil. There were no warning lights illuminated. The vehicle was taken to the local dealer, where it was diagnosed and determined that the valve cover needed to be replaced. The vehicle was repaired, but the failure recurred. There was gray smoke coming from the vehicle. The vehicle was taken back to the local dealer, where it was diagnosed that the valve stem seals needed to be replaced. The vehicle was not repaired. The manufacturer was contacted, but no additional assistance was provided. The failure mileage was approximately 53,000. The VIN was not available.

We were driving to Mci airport. We felt car jerk. Was able to continue driving. Got off at exit. Pulled over looked under hood, didn’t see anything. Pulled away felt it pulling back. Was able to make it home at just 60 miles an hour. The care would hesitate and jerk if going up slight hill or accelerating. Took to shop. They said it was pvc valve. Which caused crack in oil pan as well as timing chain cover. It also coated under car in oil. I did some research and this seems to be a fairly common issue. Same issue and results. Some of them had less miles than mine but most were around the range. I think if you investigated these engines no matter what vehicle Vw put them in you will find a common thread. I would appreciate your research and feedback in this matter. Thank you

The vehicle was towed to an independent mechanic, who observed a crack in the oil pan. The vehicle was repaired, but the failure reoccurred. The vehicle was towed back to the independent mechanic, who then diagnosed a failure with the engine. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was 50,000. The VIN was not available.

My car is a 2021 Tiguan. Car is burning oil and should not be.

The vehicle continually reports low oil pressure every 5,000 miles and checking the oil confirms that the engine has burned through 4 quarts of oil. The vehicle has been inspected by the dealership from which it was purchased, and they report that the oil burn is within normal limits as defined by Volkswagen and that they cannot produce a result that would be consistent with the level of oil during I experience during a day-to-day commute. This problem has been ongoing for over 1 year

I have to put oil into the engine every 2000 miles. The dealership has run 2 separate oil consumption tests and they claim they are unable to find anything wrong.
