2020 Volkswagen Tiguan Problems

-After turning the car on and driving a short distance, the driver dashboard made a warning sound and flashed a warning about my 'ignition system' turning itself off. After that, the entire dash (the speedometer, gas gauge, the infotainment system, the internal climate controls, etc.) went blank. The warning told me to immediately pull the car over and turn it off. Because of this, the car's external brake lights and turn signal indicators also do not work. -Because this error is happening while the vehicle is moving and is on the roadway, I am driving blind in traffic without a way to signal lane changes or when I am coming to a stop. -The car has been worked on three separate times (the alternator was replaced twice and the battery once) for this issue, but the issue is still happening. It only happens when the weather gets to be above 80 degrees. -The vehicle was taken to AutoNation Volkswagen on July 6, 2026, and the service worker who I talked to said he's seen similar issues with Volkswagens in his two and a half years that he's worked in the service department (which lines up with the VW recall for other vehicles) after I described the issue to him. He confirmed those cases also happened when the outside temperatures were high. -No, no warning messages were displayed prior to the issue spontaneously happening back in May 2026. The first warning message I got was accompanied by the dashboard going completely black. -There is a VW Safety Recall (VW Campaign 28H7) and a NHTSA Recall (23V604) for the following VW models produced between 2019 - 2020: Golf, Golf AllTrack, Golf GTI, Golf Sportswagen, and the Jetta in the United States. -VW Customer care (called on July 6, 2026) declined to take down my complaint and said they could not enter my VIN to track the error for future recalls because I quote "didn't have a VW Customer Account." They provided me with a case number (#07599604) but I'm not sure anything was logged, and I didn't qualify for 'goodwill'.

Component(s) Affected: ELECTRICAL SYSTEM: IGNITION: SWITCH, EXTERIOR LIGHTING: BRAKE LIGHTS, ELECTRICAL SYSTEM: INSTRUMENT PANEL Summary: When the interior cabin or ambient temperature becomes hot, a critical ignition/electrical failure occurs. The dashboard displays error: "Ignition has switched, please safely stop the vehicle." Immediately following, a total electrical shutdown occurs: the instrument cluster goes black, and all external signaling—including the brake lights and turn signals—stops operating. While mechanical engine propulsion is maintained, the driver is left with zero visibility of vehicle metrics and zero exterior signaling to warn trailing traffic. When restarting, the vehicle fails to crank on the first attempt and displays: "Check the starter system." The vehicle functions normally once the cabin cools down or during cold weather. Safety Risk & Consequences: This defect poses an immediate and severe crash hazard. Operating a moving vehicle without functioning brake lights or turn signals deprives surrounding motorists of critical indicators, drastically increasing the risk of a rear-end collision. Additionally, a complete loss of the instrument cluster impairs the driver’s awareness of vehicle speed and critical safety alerts. Diagnostic & Context: An independent certified mechanic diagnosed the issue as a failure of the ignition switch electrical component (not the mechanical tumbler). Thermal expansion causes the electrical contacts to fail, triggering the systemic shutdown. The mechanic noted this part is on a severe nationwide backorder, indicating widespread failure. A known safety recall exists for the VW Jetta for an identical thermal ignition switch failure; however, the VW Tiguan—which utilizes the exact same turn-key ignition switch part—is not included. Multiple online automotive forums document identical hot-weather electrical failures among other Tiguan owners, proving this is a systemic hazard that warrants a safety recall.

The contact owns a 2022 Volkswagen Tiguan. The contact stated that while stopped at a traffic light on an extremely hot day, the message that the starter was hot was displayed and the vehicle shut off unexpectedly. On another occasion, while making a turn, the vehicle stalled and lost power. The contact was able to safely coast over to the emergency lane. After waiting for the engine to cool down, the vehicle was restarted. The local dealer was not contacted. The vehicle was not diagnosed or repaired. The manufacturer was not made aware of the failure. The failure mileage was approximately 67,000.

Car has been consuming excessive oil in a short amount of time, Volkswagen claims it’s in “normal” specs but car consumes all the oil after oil change within 1200 miles. Between 0-5,000 miles 2 extra quarts will be added to engine. First time I noticed it was a month after purchasing the car when my oil/engine light came on. Recently oil cap blew off

I was driving and a vehicle was making a left hand turn, in the middle lane and they were in their lane and I was in mine, but the vehicle decided to use the automatic breaking which then cause me to have whiplash and it took a few seconds for the car to move and I had other cars behind me. Also, because this happened so quickly with no warning I first had to think did I hit the car, because I would have had no knowledge because the automatic stoping made noise and jolted me. So this is dangerous is all sorts of levels. If the other vehicle didn’t move and appeared to be fine and I had no damage to my car I would have not known.

The contact owns a 2020 Volkswagen Tiguan. The contact stated that the engine warning light was illuminated due to an emissions issue. The message to check the oil level was displayed. The contact pulled over to check the oil and added a quart of oil. The vehicle was consuming an excessive amount of engine oil. The vehicle was taken to an independent mechanic who determined that there was smoke coming from the exhaust. The contact was informed that the cylinder head valve seals had failed and caused oil to seep through the exhaust ports and was burning oil on the second head emissions system and the port was clogged. Additionally, the back over prevention camera was inoperable. The contact determined that the top half of the engine needed to be replaced. The cylinder head was on backorder. The local dealer was not contacted, and the vehicle was not diagnosed or repaired. The vehicle was not under warranty. The manufacturer was not notified of the failure. The failure mileage was approximately 55,000.

While Driving Breaks got hard to push and car system made “beep” alert with words “Break booster fault” displayed on instrument panel. Pulled over and error went away. Checked brake booster and lines. Can not get it to duplicate. Read on Volkswagen forums online that this is happening to others. Car shops unable to duplicate as well but reports online state that is has happened again after being cleared by Auto Shop.

I am getting 2 warning messages- fault electronic parking brake and error driver door contact switch. The car seems to think my door is open and therefore turns on the emergency brake for safety. This has happened when I am parked and also when I am driving.

The contact owns a 2020 Volkswagen Tiguan. The contact stated that the interior overhead console had become detached from the interior roof of the vehicle. The contact used tape to temporarily secure the console. The cause of the failure was not determined. The local dealer was notified of the failure. The manufacturer was not yet contacted. The failure mileage was 40,000.

The overhead console hangs down with wires blocking my rearview mirror and creating a blind spot on the right mirror. Volkswagon in Colorado told me that the console replacement part is on a national back order with no ETA at the time. My safety and the safety of others are put at risk because the overhead console swings while I am driving, which is a major distraction. I have to use one hand to keep the overhead console where it's supposed to be so I'm driving with one hand. Additionally, it blocks my view to my right mirror, impeding me from doing lane changes. Yes, it's been confirmed in writing from my local dealer and they are well aware of this problem because it's occurring all over the US with 2020 VW Tiguan cars. Check out this website: [XXX] Yes, my Volkswagen dealer has inspected it, however, they did not repair it because they did not have the console part. No, there were no warnings--it happened suddenly and by itself. The overhead console is made of cheap plastic and likely started dangling due to the summer heat waves which weakened the console.

The overhead console by the rear view mirror suddenly detached - only hanging by cords. It will not go back on. Duct tape will not even hold it. It is a safety hazard to drive it, and it impairs visibility. The dealership I took it to says this is a problem with 2020 tiguans, but I will have to pay for the repair.

The windshield wipers have been acting up, turning on unexpectedly when I use the turn signals, with no input from me, or when I drive over bumps, which seriously blocks my view and creates a danger on the road, especially in bad weather or during turns. This problem started showing up in October 2023 when the car had about 16,000miles, still under the 4-year/50,000-mile warranty. I took it to a dealership that month, but they checked the turn signals, scanned for faults, and found nothing, yet the issue didn’t go away. I tried again in September 2024 with another appointment, but the dealership wanted $250 for a diagnostic and to keep the car overnight, so I couldn’t proceed. The car and wiper system can be inspected if needed. There were no warning lights or messages beforehand; the trouble began in October 2023. Only the first dealership looked at it, with no fix. I have several videos showing the problem.

While driving the car looses all dashboard lights, brake lights, blinkers. The motor stays running and it has a check starter system message. Has done it several times in the 2 weeks we have owned it. Seems to only occur when it is hot outside. It is very unsafe to loose break lights, blinkers, and all info on dash while driving with no warning. It gives a pull over immediately message right after it does it. Taking it to auto repair shop this week to see what they say, but not very optimistic since I have been reading it happens a lot with this vehicle and rarely they figure out the problem.

Aftermarket headlights were purchased online. Manufactured by AKD Aokeding in China. The headlights were installed by a ASE certified tech. The left low beam light went out within minutes while driving. Headlights were removed and internals inspected. The construction of these lights are very unsafe and would not meet any manufacturer specs. Not sure how these headlights would pass any safety compliance. The internal components were loose, unsecure and fragile. The wiring used was very thin approximately 28/30 gauge diameter. Right side headlight displayed excessive heat. These lights and company products need further review for further sales to the U.S. Other complains are online about this manufacturer.

The contact owns a 2020 Volkswagen Tiguan. The contact stated that while the vehicle was parked, upon entering the vehicle, the contact became aware that the dome light had detached and fallen. The contact stated that the electrical wiring was hanging down. The dealer was made aware of the failure. The contact was informed that the failure was a known failure with similar vehicles. The vehicle was not diagnosed or repaired by an independent mechanic or dealer. The manufacturer was made aware of the failure. The contact was informed that the mileage was 2,000 miles over the extended warranty limitation. The failure mileage was approximately 76,000.

The contact owns a 2020 Volkswagen Tiguan. The contact stated that while driving 70 MPH with two toddlers inside the vehicle, the ceiling of the vehicle detached and caused a bump on the head. A dealer was contacted, and the contact was informed that it was a known issue with similar vehicles. The vehicle was not taken to a dealer or independent mechanic to be diagnosed. The contact was informed that there was a recall associated with the failure but had expired. No assistance was provided. The vehicle was not repaired. The manufacturer was notified of the failure and informed the contact about an extended warranty. The approximate failure mileage was 110,738.

The car was jerking due to a faulty transmission sensor. VW instructed the dealership to clean and reinsert the old sensor, which they state is an appropriate first step. Several days later, the cleaned part failed and caused the car to jerk and stop responding while I was driving. This jerking caused the car behind me to come very close to rear-ending me. I am concerned that VW is putting old parts back in warrantied cars, which are already known to have jerking transmission problems, to run out of the warranty. With this policy, they are putting drivers, passengers, and other cars on the road in danger.

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.

It appears that my Volkswagen Tiguan is experiencing an issue where the fuel nozzle shuts off prematurely during refueling, requiring multiple attempts to fill the tank completely. There have been no recalls on my vehicle, but it is getting to the point where I can barely fill my tank up due to prematurely shutting off. This has been an ongoing issue

Car exhaust is under car and does not come outside of under the car. We were in an accident and were told that because there are now cracks and gaps under the car that the exhaust is leaking into the body of our car and could cause co2 poisoning. If the exhaust were not under the car there wouldn’t be a safety concern

DRIVER'S SIDE REAR SEAT BELT, BEING USED WITH HIGH-BACK CHILD BOOSTER CAR SEAT (GRACO),LOCKED UP WITH CHILD IN THE CAR SEAT. THE SEAT BELT WOULD NOT RELEASE AND GOT TIGHTER AS THE CHILD TRIED TO RELEASE IT. ADULTS COULD NOT RELEASE THE BELT OR REMOVE CHILD FROM THE CAR SEAT. THE SEATBELT HAD TO BE CUT TO REMOVE THE CHILD. THE CAR SEAT HAS BEEN IN USE IN VARIOUS OTHER VEHICLES (HONDA, FORD, SUBARU AND AUDI) WITHOUT INCIDENT.

This appears to be a design defect in the interaction between the lock-off bar and the seat belt during removal. Beyond the property damage, this creates a safety risk: a caregiver who cannot remove or reinstall the seat may drive with an improperly secured car seat, and a damaged or cut vehicle belt in that seating position is unusable until repaired. I reported this to Evenflo’s ParentLink support on 7/19/2026 (ref:!00Df402dTF0.!500Uy0uvwTd:ref). Evenflo responded that the tangling meant I “incorrectly followed” a step, without asking any diagnostic questions, and denied reimbursement. My requests for escalation on 7/21 and 7/23 have gone unanswered. Photos of the seat, the belt path, and the cut belt are available on request.

GOOD EVENING, I WOULD LIKE TO KNOW THE BEST PERSON TO COMMUNICATE WITH REGARDING THE DISCREPANCIES I HAVE RECENTLY FOUND ON MY TITLE, REGISTRATION, AND INSPECTION FORM. MY NAMES SEEM TO BE INCONSISTENT ON THE FORMS. THE INSPECTION FORM ALSO INDICATES THAT THE LEFT WHEEL AND RIGHT WHEEL HAVE BEEN REMOVED ACCORDING TO THE INSPECTION FORM. THERE IS ADDITIONAL INFORMATION THAT MAY HELP INVESTIGATE THIS MATTER. PLEASE FEEL FREE TO E-MAIL ME AT YOUR EARLIEST CONVENIENCE AT [XXX] THANK YOU AND I LOOK FORWARD TO SPEAKING WITH YOU.

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.

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.

On three separate occasions the power steering unit lost power, after restarting the car it would work again.

Hit head on by other vehicle and airbags did not deploy.
