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 the federal safety agency 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 the federal safety agency investigate this issue for the 2021 Tiguan model year.

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 the federal safety agency investigate these widespread PCV and oil consumption failures in 2021 Volkswagen Tiguan vehicles.

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.

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.

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.
