2020 VOLKSWAGEN TIGUAN Engine Problems

The contact owns a 2020 Volkswagen Tiguan. The contact stated that after adding a quart of oil, the contact became aware that almost every three weeks there was blue smoke coming from the exhaust pipes. The contact stated that the oil warning light was illuminated. The vehicle was taken to an independent mechanic to be diagnosed, and it was determined that the engine was consuming an excessive amount of engine oil. The vehicle was not repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 68,000.

I am reporting excessive engine oil consumption on my 2020 Volkswagen Tiguan. The vehicle consumes approximately one quart of oil per 1,000 miles. The vehicle has already undergone multiple diagnostic and repair attempts, including PCV-related repairs, all paid by the owner. Despite these repairs, the excessive oil consumption continues. Volkswagen and the dealership have stated that this level of oil consumption is “within range” and have required additional paid testing to further evaluate the issue, even though prior repairs failed to resolve it. I am concerned this reflects a broader engine design or component issue, as similar oil consumption problems have been widely reported by other Tiguan owners. I am submitting this complaint to document the issue and request further review. THE ISSUE OF OIL COSUMPTION WAS REPORTED AFTER THE THIRD OR FOURTH OIL CHANGE BEFORE THE 50,000 MILES WARANTY.

The crankcase breather valve (PCV system) on my 2020 Volkswagen Tiguan failed, which caused catastrophic engine damage. VW Southtown diagnosed the engine as condemned and stated that a full engine replacement is required. Prior to the engine being condemned, I have already spent $3,787.59 in repairs at VW Southtown addressing recurring oil-related issues caused by the PCV valve being stuck closed. This caused an excessive crankcase pressure buildup of over 0.5 psi, as documented on the VW service repair order. The failure occurred while my husband was driving our [XXX] son in the car, and the warning message immediately displayed on the dashboard was: “12V battery not charging. Stop engine.” This sudden loss of engine function and dashboard warning posed a serious safety risk, as it could have resulted in loss of power or control while driving. The problem has been confirmed and documented by an authorized VW service department, including detailed repair orders and technical diagnosis. Prior to failure, there were oil-related warning lights and symptoms of excessive oil pressure, which appeared intermittently and indicated the underlying PCV failure. Research indicates this is a known, widespread issue affecting 2020–2021 Tiguans, with multiple owners reporting breather valve/PCV failures leading to oil loss, excessive crankcase pressure, and engine damage.

Exceeding manufacturer recommended oil consumption. Car emits white smok out of the exhaust upon start up. The vehicle has been in the shop three times for this problem. The first time valve seals were replaced. The second time the oil pressure regulator was replaced the third time the recommended fix is to replace the engine head however they are nationally on backorder for months now so the fix has yet to be applied. Personal research has resulted in numerous Facebook groups and reddit post of customers with the exact same story.

The vehicle has had repeated failures of the oil filter adapter to block gasket. This gasket has been replaced three times in 41,000 miles. There appears to be a failure on the part of the gasket. The vehicle has been repaired for the third time, the gasket remains with the dealership where it was repaired. I do have photos of the gasket. A catastrophic failure would result in radiator fluid pouring out of the vehicle, causing the vehicle to come to a complete stop, regardless of location. This problem has occurred three times within 41,000 miles. The part has been inspected b the mechanic who replaced it. There is no warning other than to watch for leaks.

I have been experiencing a noticeable delay in throttle response when accelerating, particularly when attempting to slowly merge into traffic. For example, when I press the accelerator to make a left turn, my Tiguan hesitates for approximately 2-3 seconds before responding, creating a significant safety concern as I find myself stuck in oncoming traffic. I took the vehicle to the dealership for diagnostic testing, but no fault codes were detected, and no warning lights were illuminated. To demonstrate the issue, I had to conduct a test drive with the mechanic. Following this, the mechanic escalated the issue to the quality engineering team at Volkswagen. They acknowledged that they were aware of this problem but stated that there is no available fix. I was advised to use top-tier premium fuel and switch to manual mode to potentially mitigate the delay. When I escalated this issue to the VW Customer Care, they claim that it is operating as designed and no repairs would be made. I suspect that this issue stems from a defect in the vehicle's control software, which VW appears to be aware of but has not addressed with a permanent solution.

I currently reside in Texas where it get HOT during the summer months. I recently got this car back in May. Recently when it’s hot outside my car had cut off one day in traffic and said please check starter system. All electrical components of the car shut off completely. The engine will start run. But the AC, lights, back up camera, windows stop working. I have an appt to drop the car off at the dealership. I been seeing this is an ongoing problem for. VW vehicles I have seen multiple stories about this happening mainly in 2019-2020 jettas. This needs to be an investigation on VW and this problem.

The motor mounts failed and need to be replaced, the car has never been in an accident or even driven in harsh conditions. There is another part that failed in the engine which causes it to leak oil. The vehicle has a hard time accelerating intermittently.

While driving vehicle spontaneously shuts off with the following warnings "ignition system off. Pull over safely", "Check starter". This has occurred more than once when I was traveling over 50 mph and could have led to a severe crash if I were not fortunate enough to have minimal traffic in the area at the time. I have brought it into the dealer and they were unable to identify the cause. Instead, they replaced the battery and front right speed sensor. The problem of my vehicle spontaneously shutting off has only persisted on 4 more occasions after this visit to the dealer.

Since the day I bought this car from the dealer (who stated oil change should be every 10K miles), the car's engine oil light goes on every 5-6 months. This is a new car and never goes past 6-7K miles on the engine. I believe there is an engine oil consumption problem with these type of vehicles. This is a safety hazard. Additionally, it is unheard of to have to replace oil in a brand new car in the 21st century every 5-6 months. Please help me with this. I am still making car payments on a car that is flawed!

There is a major lag in acceleration. It happens randomly so taking to a dealership won’t help because they will only try one time then say they can’t reproduce the problem. From a stop or turning into a lane I can have the pedal to the floor and the car just stalls and doesn’t go. After a few seconds the car finally gets a boost then goes. Well personally those seconds could lead to a car hitting me. I have asked my local dealership many times about it and they don’t seem to care or want to look into a problem. The idea of a car is hit pedal and it goes but not the Tiguan. There is a known problem and this should be fixed. This has been going on since I purchased car. Just getting tired of this situation.

The auto break feature will illuminate on the dashboard and then send my car to a screeching halt. It takes me on average 5 seconds to regain control of my brakes. It has happened exiting businesses (small curbs) but also on the main streets with no one else around going upwards of 45 mph. The infotainment system that houses the parking and rear view safety features as well as navigation also does not work when the car is left outside in weather above 80 degrees. The AC is also unable to cool when the weather is above 80 degrees all of these ‘safety features’ make the car dangerous.

The vehicle burns oil. When the dealer was confronted they said it was “normal” for the car to burn half a quart of oil every 2000 miles. No oil stains on the ground. The engine is burning the oil.

ERC code popped up on Dashboard while driving in 2021 and the vehicle wouldn't go over 30 mph. Took it to the Volkswagen dealership in November 2021. Between November and February of 2022, I took the vehicle back, after having it for less than 2 hours, with the same ongoing issue. Started having the same issues after the final pick up. Fast forward to November of 2022, in addition to the ERC, my vehicle battery drained and I am unable to start the car unless I jump start it. Replaced the battery and still the same issue. The battery does not stay charged and it is a brand new battery.

This car burns oil. I am adding at 1-2 quarts of oil every 2-3 months and I only have 24k miles on this car. I've had an oil consumption test completed and they said that its falling just with in normal limits. It's unacceptable. Additionally, the emergency braking system is faulty, it will register shadows or on a slightly winding road will register on coming traffic and slam on brakes. I have had cars blowing their horns and swerving from behind me in order to avoid a collision. I had that check as well and their advise was to disable it. WHAT?!? So either I disable a safety system or I get rear-ended. This is a joke and completely unacceptable.

Low Engine Oil. Car is burning oil. Having to put engine oil every 3 months.

MY 2020 VOLKSWAGON TIGUAN STALLS WHILE IDLING IN TRAFFIC. THE ENGINE MAKES A GRINDING NOISE AND THERE IS NO POWER. I HAVE TO PUT IT IN PARK AND TURN IT OFF AND THEN BACK ON. IT HAPPENED SEVERAL TIMES IN 2021 AND THE DEALER REPLACED THE STARTER-THAT WORKED FOR A WHILE BUT IN THE PAST 7 DAYS (MAY 30, 2022 TO JUNE 6, 2022) IT HAS STALLED 5 TIMES WHILE IDLING IN TRAFFIC.

Complete engine stoppage approximately 18:00 21 July 2021. Headed east on Germany Road, a serpentine two lane road with no shoulder. Engine stopped and vehivle coasted to a stop. I turned on the emergency lights and put the vehicle in park. Fortunately, I was able to restart the car and proceed. It was pure luck that I wasn't rear-ended.

The contact's fiancé owned a 2020 Volkswagen Tiguan. The contact stated while his fiancé was driving 30 mph when the steering wheel and the entire vehicle began to shake. The contact stated the Electronic Throttle Control warning light was illuminated. The driver was distracted by the failure, which caused her to run a red light and crash into another vehicle. All front and side air bags deployed. The driver did not sustain any injuries or seek medical attention. The contact stated his mother was seated at the rear driver side and did sustain injuries on both of her knees and sought medical attention on the day of the accident and also the following day. The contact stated unknown person in the other vehicle sustain also injuries on their knee. A police report was filed. The insurance company deemed the vehicle totaled. The vehicle was towed to the insurance lot. The contact called the local dealer and was made aware of the failure. The manufacturer had not been informed of the failure. The failure mileage was approximately 7,139.

THE VEHICLE BEGAN TO FAIL WHILE PARKED, THE CHECK ENGINE AND EPC LIGHTS CAME ON. IT BEGAN TO FAIL AS IF IT HAD NO STRENGTH. ON DECEMBER 23, THE DEALER WAS TAKEN FOR THE THIRD TIME DUE TO THE SAME PROBLEM, THE FIRST TIME THEY TOLD US THAT IT WAS GASOLINE (PUMA) THAT THAT BRAND COULD NOT BE USED, THEY CHANGED THE BRAND TO SHELL AND CONTINUED WITH THE PROBLEM. BEFORE THIS HAPPENED, THE DELER MADE US A RECALL OF SOMETHING AND AFTER THIS IT WAS THAT THE FAILURES BEGAN. THE BUS ONLY HAS 3,500 MILES. THE LAST THING THEY TOLD US THAT WHAT IS DAMAGED IS THE EVAPORATOR TODAY IS DECEMBER 30 AND THEY HAVE NOT RETURNED THE VEHICLE TO ME. THE PASSENGER SIDE OF THE SUSPENSION SOUNDS WHEN YOU GET A BUMP OR A HOLE IN THE ROAD AND TELL US THAT IT IS NORMAL IN THE VEHICLE.

MY CHANGE OIL SERVICE LIGHT CAME ON AND KEPT REMINDING ME DAILY FOR 10 DAYS THAT I NEEDED AN OIL CHANGE. I TOOK IT TO THE LOCAL DEALERSHIP TODAY AND THEY SAID THEY WOULD ONLY CHANGE THE OIL AT 10,000 MILES. I ONLY HAD 5800 MILES BUT THE OIL WAS LOW SO THEY ADDED OIL. I HAVEN'T EVEN HAD THE CAR 6 MONTHS. WHAT IS WRONG WITH THE NEW ENGINES OR SHOULD THE OIL REALLY BE CHANGED AT 6000 MILES? I SHOULD NOT BE HAVING ISSUES WITH A BRAND NEW VEHICLE. SOMETHING NEEDS TO BE DONE BY VOLKSWAGEN TO CORRECT THIS ISSUE.

BOUGHT CAR ON 4/6/ 2020 BRAND NEW AT 2600 MILES OIL LITE CAME ON I CHECKED AND IT NEEDED 1 QUART.I WENT TO DEALER THEY CHECKED IT AND ADDED 1 QUART AND TOLD ME TO COME BACK WHEN IT HAPPENS AGAIN .
