The contact owns a 2021 Volkswagen Tiguan. The contact stated that while driving downhill at an undisclosed speed, the vehicle lost automotive power. The vehicle was coasted into a driveway and restarted. Upon restarting the vehicle, the electronic power control (EPC) warning light and the yellow triangle for the central warning light illuminated. The vehicle was idling roughly and jerking while driving to the dealer. The vehicle was previously serviced at 50,500 miles due to an EPC fault, and dealer replaced an electronic actuator. Additionally, the battery was replaced at 50,500 miles, and the vehicle was repaired. The manufacturer was notified of the failure. The failure mileage was 51,960.

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

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.

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.

The check oil light indicated that the oil level had become too low. The Volswagen dealership service technician identiifed the cause to be from the exhaust valve seals wearing out. The cylinder head needs to be replaced per their recommendation. No warning apart from the low oil indicator.

2021 Volkswagen Tijuan has an oil leak caused by a defective Timing Cover Gasket, and or PCV component(s). If you do a simple Google search, there are thousands of these vehicles experiencing the exact same issue, and numerous individuals are not happy. The warranty is 4 years or 50k miles, this problem occurred at 53K, very convenient for the dealers repairing these vehicles. This is absolutely a design flaw and should qualify for a recall. Please investigate and I am sure you will agree, thank you so much.

PCV Failure causing the timing cover to leak oil and causing the oil pan to crack. This is a known issue with VW TSI engines. This PCV is a major issue not only causing the damage above but others are having to replace the rear main seal and crank case because of this. It's now in the shop for the next week and I'm out of a vehicle for the next week. This is not the only problem I've had with this vehicle. The last problem I had was the housing unit of the overhead lights, sunroof controls and sos when hanging down and broke out of nowhere. The plastic melted and cracked. It was replaced but was not put back together properly. There are now gaps where it should be tightly sealed. The glove comparent arm is broken. There are wheel bearings issues too we are trying to pin point the issue. The hits keep coming and the car is just a money pit.

My Tiguan was towed on [XXX] to Beyer Volkswagen [4017 Valley Pike, Winchester, VA 22602] for service to repair a sudden and unexpected vehicle failure.  On [XXX], I started the Tiguan and noticed a hard start. I drove the vehicle about 4 miles down the road and noticed a smell of gasoline when I stopped and opened the door. I immediately drove the car home at which point I noticed gasoline on the road and driveway, as well as a heavy persistent smell of gas. I moved the vehicle to the road and had it towed [$95 at my expense] to Beyer VW for service. This failure rendered the vehicle undrivable and luckily was able to get it towed before it became engulfed in flames. [XXX], after getting the vehicle back for 1 week (dealership claiming repair fixed) the problem was not fixed and in fact gas spewed from the engine at a higher rate. Pictures attach showing about of gas which instantly dispelled at start and move from driveway to road. This is a critical vw problem that will result in fire.

So this is not related to a specific incident, more long term. The throttle response in this vehicle is downright dangerous. MAny of times I feel like I am going to cause an accident. The throttle response is so laggy and jerky that off the line it seems to hesitate for almost 2 seconds. Light turns yellow? Good luck, it will barely downshift and get moving before it turns red. Sometimes the response is good, sometimes it terrible. No predictability. Have to turn it to sport mode when I have to make a left turn into traffic just to get a jump start. There are numerous forums that have talked about the issue. I have even brought it up to the dealership with no fix recommended. I have driven so many cars in my day, not one like this. Thinking about selling the car back just to get something safer unless they come out with a fix for it.

The contact owns a 2021 Volkswagen Tiguan. The contact stated while driving out of the driveway at approximately 5 MPH, the parking brakes engaged independently. An alert stating that the vehicle is in motion was heard. The contact turned off and restarted the vehicle, and was able to continue to drive; however, the failure reoccurred while driving on the highway. The vehicle was towed to the local dealer. The dealer informed the contact that they were unable to diagnose the failure. The manufacturer was notified of the failure but provide no assistance. The approximate failure mileage was 7,000.

Higher-selling and older vehicles accumulate more reports. Counts are not failure rates and are not directly comparable between vehicles that sold in very different numbers.
