2021 Volkswagen Tiguan Engine Problems

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.

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 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.

Tiguans have been reporting excessive burning oil consumption- reported this to the dealership and consider this "normal" but how is going through several oil containers to make sure there's enough oil in the car "normal"??? I've never had this issue with any other car- other Tiguan owners have reported this issue and it's over a 6k repair.

Here is a quick description of the issue from our Volkswagon of Huntington service report. We have had this ongoing issue for a few months now. the check engine light will come on. We get it checked, we replace a sensor, and all is good for a day or week. Then we do it again, replacing a different sensor. Now the dealer is saying the oil separator is leaking and requires repairs starting at $8,400 and going up from there as they uncover more. We have always maintained the car properly. From research this appears to be a very known issue with this model car and should be reported and covered by VW. SCANNED VEHICLE AND FOUND FAULTS PRESENT FOR SECONDARY AIR. OBSERVED OIL SEPARATOR LEAKING CUASING UPPER TIMING COVER GASKETS TO BLOW OUT ALLOWING OIL TO ESCAPE. FOUND SECONDARY AIR PORTS IN CYLINDER HEAD CLOGGED TRIGGERING CHECK ENGINE LIGHT. ADVISED TO REPLACE OIL SEPARATOR,CAM SHAFT MAGNETS AND CYLINDER HEAD TO START. APPROX $ 8480.00 PLUS TAX

After oil changes (always maintained at dealerships) it would require a quart of oil with in 2 days. Random starts will blow smoke out the rear. random sluggish behavior. Dealership confirmed PCV valve is causing a buildup in engine pressure which caused a premature oil pan gasket leak. Without full teardown cannot know full extent of damages caused. (which spills out of the bottom and towards tires.....) dealership and fellow Tiguan owners have all reported the same issue! with a repair cost of $1,000-8,000+. same with alot of other years as well.. The date below that i will list is for when the problem was fully confirmed (89k miles) but has always been an issue told its fine ... really noticed it after (68k miles) when i purchased the vehicle. With how many people are dealing with this it is hard to understand how we dont see an open recall for them..... also dealer said pvc valves are on back order and have been. why should one replace with oem if they won't acknowledge its a faulty part?

Check Engine Light came on and got estimate from Pete Moore VW Dealer in Pensacola, Florida and was told the car needed extensive engine repair which included a new cylinder head part. So we waited to come get the car repaired on 3/5/2026 once we had saved up the money for it. We found out the cylinder head is on a Nationwide back order with NO estimated time to get it fixed properly. The technician who gave us the estimate back in September 2025 failed to mention that the cylinder head has been on a Nationwide back order during that time. I am not the only person dealing with this issue in the USA but feel VW has not provided a fix or estimate time to repair these cars properly causing a safety hazard. This time to wait for a part is unacceptable and feel our cars fall under the Lemon Law.

I am experiencing severe oil consumption and leakage with my 2021 Volkswagen Tiguan. The low oil level light began coming on weekly, and I have had to add oil nearly every week to keep the engine from running dry. Recently, I noticed oil leaking underneath the vehicle and immediately parked it. After parking, the vehicle began leaking oil excessively. The problem appears related to PCV system failure, which has caused multiple oil seals to rupture. After researching online, I found many other Tiguan owners reporting the same issues — including PCV valve failure, cracked oil pans, damaged valve seals, and crankshaft seal failures. My vehicle is no longer under the manufacturer’s warranty, and the dealership has not provided a fix. This defect presents a major safety concern because the engine can suddenly lose oil pressure or seize while driving, leading to sudden loss of power or control, which could cause an accident and potential injury. It appears Volkswagen has been aware of similar issues in other model years, but has not issued a recall or permanent repair for this problem. There is currently a class action lawsuit for the exact same issue for 2022 - 2023 Volkswagen Tiguan but doesn't currently include the 2021 Tiguan that I have. I am requesting that NHTSA investigate these widespread PCV and oil consumption failures in 2021 Volkswagen Tiguan vehicles.

The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving at an undisclosed speed, the contact's dad who was following behind the vehicle noticed oil splashing onto the front windshield of his vehicle. The contact's dad then noticed while the contact was driving uphill, oil was splashing out of the oil pan. In addition, the contact's dad noticed smoke coming out of the exhaust. The check engine and PCV warning lights were illuminated. The vehicle was driven to the shoulder of the road. The vehicle was inspected, and the contact's dad noticed that the oil pan was completely empty. The vehicle was towed to an independent mechanic, where it was diagnosed with a cracked oil pan. The contact was informed that the oil pan, gasket, and filter needed to be replaced. The vehicle was repaired; however, the failure reoccurred. The contact stated that while driving at an undisclosed speed, the contact's dad noticed the oil splashing underneath the vehicle again. The vehicle was driven to the shoulder of the road. The vehicle was inspected, and the contact noticed that oil was spilling out onto the road. The oil pan was empty. The vehicle was towed back to the independent mechanic. The independent mechanic contacted the dealer. The independent mechanic was informed that this was a known failure with the vehicle. The independent mechanic was informed that the failure was that the PCV valve had either failed or was clogged. The independent mechanic was informed that the failure normally occurred between 60,000-100,000 miles. The contact was informed that the failure might recur after the repair, however there was no recall for the failure. The vehicle was being repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 93,000.

The 2021 Tiguan, R-Line that I own now requires a new engine after roughly 70,000. The engine is no longer under warranty, According to the VW Dealership, this is what is wrong with the engine - Based on our observations and diagnostic review, we have determined that damage to the rotating assembly was caused by the presence of one or more metal objects entering the engine. This type of foreign-object intrusion can lead to significant internal impact, which is consistent with the damage we found during our assessment. Also, if you do a search on Reddit and other public forums, there are a lot of 2021 VW Tiguan's with similar issues.

I’ve had my Volkswagen Tiguen since 2021 fresh off the lot. I have been the only owner of the car at about 30,000 miles my head gasket blew, causing the engine to go into default after weeks in the dealer. They replaced the head gasket and stitched it up, the head gasket blew again at this point I was still under warranty so they agreed to replace the engine. It drove fine after the engine was replaced this year 2025. I started to have a whole host of problems. It began to jerk and hesitate at acceleration. My engine light came on with continuous jerking upon acceleration for weeks until I started to lose power in my engine. I couldn’t go over 50 60 mph. I would always pull the car over power it off and power it back on just to see if it would change and it didn’t do much I had a local mechanic add oil to each tire also drain the engine, which had shards of metal in it. And basically stitch the car back together until we can figure out the bigger issues. It’s only been a day since the oil was added to each tire. I had a very violent jerk of the engine, which made it feel and sound like I blew a tire I got out to look at the tire and it was just fine. It was the backfire of the engine going into the exhaust that caused such the violent jerk. Happy that no one was on the road. If somebody was behind me it would’ve easily been an accident. Most of these dealerships know exactly what’s going on and have been avoiding the big conversation of what to do next they rather just replace and Band-Aid these things into the consumer just gives up. I have two small children and this is the only means of transportation. I’m fearful that I’ll be stuck with a car note for a car. I can’t drive.

Check engine light came on with excessive oil leaking from engine. Dealer inspected and diagnosed the PCV/Oil separator had failed, multiple valve stem seals had failed, and valve stem guides were worn causing excessive crankcase pressure. Dealer recommended cylinder head replacement. Vehicle has been at the dealer a month with the cylinder head on backorder and no timeline for resolution. Dealer indicated thousands of cylinder heads in the queue, with tens of units being distributed per month.

2021 Volkswagen Tiguan, Approximately 40,000 miles
Date of failure: Oct 12th, 2025
Component(s): Engine, Powertrain, Vehicle Speed Control, Throttle body Description of the problem:
My 2021 Volkswagen Tiguan experienced a complete engine failure despite having multiple prior service visits for engine-related issues while it was still under warranty. During the warranty period, I brought the vehicle to Grand Junction Volkswagen (Grand Junction, CO) several times for problems including: * Excessive oil consumption * “Check coolant” warning light turning on * EPC (Engine Power Control) mode activating and loss of power The dealership performed an oil consumption test and told me the results were “normal,” but they did not address the coolant light or EPC issues, stating these conditions were within normal limits. The same problems continued after each visit. At approximately 40,000 miles, the engine failed completely while driving, leaving the vehicle inoperable and creating a significant safety risk. The vehicle had to be towed. Volkswagen is now denying liability, claiming the vehicle is out of warranty, even though the same engine problems were documented repeatedly while it was still under warranty. I have opened a case with Volkswagen of America Customer Care (Case #07085098), but there has been no resolution so far. Safety concern:
This issue poses a serious safety hazard. The vehicle can lose power suddenly and stall while in motion, which could lead to a crash or leave occupants stranded in unsafe conditions.

Subject: Complaint Regarding 2021 Volkswagen Tiguan – Premature Engine Failure at 46,000 Miles To Whom It May Concern, I am filing a complaint regarding my 2021 Volkswagen Tiguan (VIN: [XXX] ) which suffered a catastrophic engine failure at only 46,000 miles. •I purchased the vehicle used in August 2023 through CarMax Auto Finance. •At the time of failure, the car had fewer than 50,000 miles and had been properly maintained. •Despite the extremely low mileage, Volkswagen has refused to cover the repair under warranty because the vehicle is slightly past the 4-year time limit. I believe this is unfair and unreasonable. A major component such as the engine should not fail this early, and a vehicle sold under these conditions is not fit for its ordinary purpose. Because of this premature failure, I was left with no functional car but still obligated to pay the outstanding loan balance. This has caused severe financial hardship and forced me to dispose of the vehicle below value. Requested Action: 1.That Volkswagen cover or reimburse the cost of the engine replacement, OR 2.Provide financial relief toward the remaining auto loan balance.

I purchased about 4 months ago with about 139,000 miles on it. The vehicle now has 142,000 miles and is experiencing excessive oil consumption—approximately 0.9 quarts per 600 miles. VW seems to be pushing this off and as I try to use my extended warranty I purchased when I got the car, AUL has asked for an engine tear down. VW knows about this issue, as it is internally a known issue for this model, yet they are unwilling to help. At time of purchase, this issue was not disclosed to me, as such had it been, I would not have chosen this car.
