Electrical System Problems of Volkswagen Tiguan - part 1

When driving, the vehicle self shifted into neutral and was unresponsive. All of the dash warning lights came on and I was not able to apply throttle or shift the car into drive. I had to coast in neutral to the side of the road. This is a safety issue and there was a high possibly of crashing if it wasn’t on a rural road. This is the second time this has happened. The first time vw service said nothing had occurred and gave me my vehicle back.

The contact owns a 2025 Volkswagen Tiguan. The contact stated that while driving approximately 55-60 mph, the vehicle suddenly became inoperable; the power steering became inoperable, and the brake pedal became difficult to depress. The message "no key fob detected" illuminated. The vehicle was taken to the dealer, but the failure could not be duplicated. No repairs were performed. The manufacturer was notified of the failure. The failure mileage was unavailable. The VIN was unavailable.

I was driving in 4 lane town traffic going under 10 mph and the hazard lights came on by themselves, and the car died. Propulsion stopped. Fortunately I was able to pull onto a striped median, and once I was over shock, 3-5 ish minutes, I started the car and drove to the dealership. I don’t remember any warning message, and it seems like the steering and brakes were hard once it was dieing, but I was so shocked it’s hard to remember exactly. This happened in rainy weather, about 65 degrees around [xxx] on [xxx], in bentonville, ar. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

Tha back up camera system is glitching out. We reset the system but is keeps freezing/blacking out after about 30 seconds. This is known issue with this model of Volkswagen.

Out 2026 Tiguan se line the first day when we drove the veh home it had a bad vibration and brake problems hvac system locking up unable to control the fan speed was raining out and the fan speed was inoperative had to pull over due to fogged up windows . The brake system when stopped at a light in traffic it will not hold the veh moves forward while the brake pedal is depressed firmly and in stop and go traffic the brake pedal gets hard . When backing up the the brakes violently apply scares you . The veh had only 384 miles on it the first time in the said they fixed now several weeks later it is back for the same problem . They said they do not know how to fix it .

The car stopped at a light on a busy street in [xxx] (in the middle lane), then the engine stopped, and my wife could not restart it. I went as fast as possible and met her. I was eventually able to get it started. This is the third time we have had problems like this. I did the same thing for me and another time for my wife. I believe it is the stop-start capability, but I can't say for sure. We have also had bad engine oil burning problems and electrical problems. All of these (I now know, but did not before) are recurring problems for 2019 Tiguans. The cylinder head was rebuilt last year, associated with a similar instance. I am now fully aware that the 2019 Tiguans are known to experience all of these problems, but when I brought my car in on previous occasions, that never got mentioned. I am told xyz is an issue, then billed for repairs. The car was originally leased, and when I purchased it at the end of the lease, I also purchased a full premium warranty. When the issue happened in may of 2025, the policy eventually covered this, but it took over a month of justifications and records before the third-party insurance company agreed to cover the repairs. All of this said, I am no longer comfortable that this car is safe for my wife to drive, as the issues that are repeating are known issues, and yet Volkswagen seems to sweep these under the rug from both a manufacturer and dealership perspective.

While driving on the highway in my 2023 Volkswagen Tiguan (approximately 70,068 miles), the epc warning light and oil warning light illuminated and the vehicle began to stall/lose power. I exited the highway immediately and shut the vehicle down safely. A substantial amount of engine oil leaked from underneath the vehicle after stopping. The vehicle was towed to a Volkswagen dealership. Dealer diagnosis included: * cracked oil pan, * oil separator failure, * and timing chain cover leak. The dealership advised there was no metal contamination found in the oil or filter and no confirmed catastrophic internal engine failure at this time, though the long-term condition of the engine cannot be guaranteed after the oil-loss event. I am submitting this report because the sudden oil-loss event and stalling condition occurred while driving on the highway and created a potential safety hazard.

Vehicle was just turned on and put into reverse. Dash and infotainment center lights flashed and shut off. Vehicle rolled backwards uncontrollably down a sloped driveway. Steering and brakes were not properly functioning. Vehicle came to a stop when it struck a parked vehicle in its path.

The problem occurred immediately after picking my car up from a valet on 5/17/2026 around 9:00pm. The valet had pulled my car up to the front of the seattle park ‘n fly valet by sea-tac airport. I pulled out onto International blvd, and within a few seconds, the accelerator pedal became completely unresponsive. I was able to coast the car into the denny’s parking lot just north of the valet lot (about 0. 2 mi north of the valet). Everything else seemed to work just fine, except for the accelerator pedal (brakes worked just fine). I turned off the engine, and when I tried to restart the car, it was turning over but wouldn’t start. I called out someone to jump the battery, but the battery was fine. We then disconnected and reconnected the battery, and this resolved the issue and I was able to restart the car and drive away. It was dangerous that I was able to pull out onto a road, just to immediately lose any ability to accelerate. I’m lucky there was a nearby parking lot and I didn’t pull into busy traffic. Something seems to have happened at the valet, that was then triggered as soon as I pulled out onto the road. My guess is they tried to start the car and use the twist shifter in some combination that caused a fault that only triggered once I started to get up to speed. It’s strange because they were able to pull my car up to the front of the lot just fine, and I was able to pull out onto the roadway just fine, but the loss of acceleration only happened once I tried to get it up to speed.

Center roof console fell out while driving vw states it out of extended warranty charging $200 for repair I find this very dangerous.

When it is really hot outside 90 and above my car does messes up. As I'm driving my car will throw the code pull over and check starter system. Everything turns off, and then it takes minutes from my car to restart. It has happened multiple times when I'm in traffic at a stop light or driving and it throws the code as my car is moving. I have taken it to shops and still no auto shop can figure out the fix. Happened for the first time a year ago, and now its happening constantly.

The vehicle experiences sudden loss of motive power during acceleration. Between 30–60 mph, the transmission fails to upshift correctly, causing the engine rpms to spike to 5000 while the vehicle fails to gain speed. This creates a severe safety hazard when merging into high-speed traffic. Additionally, the infotainment system frequently blackouts and reboots while driving, and there are intermittent malfunctions with the power windows and door locks. Authorized dealerships have been unable to resolve these persistent safety defects after multiple repair attempts.

While driving my car, I get a loud beep and all of a sudden it says system switch failure pull over safely. It seems to do this on hot days. We thought it was maybe the battery and replaced that at $280. It was fine for about a week and then started doing it again. Everything on my dashboard goes completely blank my ac stops working I cannot see my gauges. Nothing works. It’s very scary especially when you’re driving. You can’t see your speed. Even the manual speed goes out my gas meter doesn’t work. None of the meters work. I just bought this car six months ago. This is absolutely insane and after looking up what is going on with my car this seems to be a very common occurrence which would make me wonder if the ignition switches need to be replaced or the 645 relay is faulty, but it’s not adding up something absolutely needs to be done. It’s an unsafe occurrence that could potentially kill someone while they’re driving.

The vehicle will randomly shut off while driving. A message will appear stating "check the starting system" attempts to restart the engine are unsuccessful. The engine will start, stall after about 2 seconds and the message "check starting system" will display. The first time it happened, I was turning a corner at a rather dangerous intersection and the vehicle stalled. It took about three attempts before the engine would remain running. When the engine would stall the dash would go dark and the engine would not remain running this happened about a month ago in hot weather. It occurred again on April 25th, 2026 way worse this time. The temperature in the area reached 91 degrees fahrenheit. My vehicle was sitting outside in the heat for at least 5 hours, same issue, the vehicle would then proceed to stall in the middle of the freeway, I was able to coast to the breakdown lane where the vehicle would remain unable to start and the message "check starter system" would display. Looking on NHTSA webpage before filing a complaint, it seems that this is a rather common issue. Vw had a recall for other models (campaign 28h7) for models such as the jetta, golf and other like models. This is a really dangerous issue and could end up getting someone seriously injured or worse killed in a collision if my vehicle stalls like this. The vehicle is scheduled for a service appointment in the near future (local vw dealer is at least 2 weeks out before they can even look at my vehicle) after viewing this information, I can't help but believe it is possible the 28h7 recall is affecting more models than anticipated.

The travel assist warning displays frequently depending on where hands are positioned on steering wheel. Sound is a distraction while driving and hand placement can to unsafe to avoid the warning being triggered. I have had the steering wheel replaced due to the issue but now with the new steering wheel the problem is back.

2018 vw Tiguan. The fuel injector harness failed. There is a NHTSA letter stating 2018-2019 Tiguans had this issue and there’s an extended warranty up to 120,000 miles. My Tiguan is at 91,000 miles, but vw is saying the warranty isn’t assigned to my VIN. So there’s a warranty for this exact issue and year, but my vehicle isn’t covered. This warranty obviously needs to be extended by build date as it’s a pretty costly repair.

When I’m stopped, the car sometimes shuts off. The horn works intermittently. When I start the car, it feels like it’s going to stall. At times, all of the dashboard warning lights come on. Also, when I’m backing out of my driveway with nothing behind me, the car will sometimes automatically brake hard.

When I am driving my vehicle, I get an alert that the "ignition switched off, please safely stop the video". All electrical power to the vehicle subsequently drops off. This is the same issue that the 2018-2019 vw jetta's were recalled for in 2023.

So we took it into Volkswagen in texarkana texas. They had the car for an entire week. They said they updated something. The first day we got it back. My daughter drove it and the lane assist turned off. The dealership told us it’s a known issue and then it happens when it’s in the sun well, this was at night at eight something p. M. I’m attaching a photo. If this is a known issue because we called another dealership in another town there might need to be a recall, issued or figure out what the problem is or maybe this is just a lemon, but I want to keep documenting it because I keep taking it in and it’s not being fixed. What would you suggest we do next?.

Parking brake violently engaging with every stop.

When driving car will read error code that states there is problem with the starter and shuts off all electric components while engine is still running. Has happened multiple times since initial incident.

When the weather is warm or hot the car will drive less than a mile then cuts off but still drives. No air conditioning no radio or camera works how car shuts off but can still drive.

Travel assist not available notification pops up on the dashboard and makes a loud distracting ding noise randomly and repeatedly. Volkswagen has no fix for it except “replace the steering wheel” which I’ve done twice. They need to push a software update so I can silence this thing.

Vehicle purchase on 3/18/2026 with 17 miles. At 30 miles the sos button started flashing red, then green, then red then no light at all. I called dealership and was made to think it was no big deal and that a dealership has to reset. I also let them know my info center was freezing. Took car back to dealership 6 hours away - they had car for 5 days and when I got in the same issue of the info screen freezing was present. Sos button was fixed. I also gave them a list of many issues that needed to be looked at that I felt were not addressed or resolved. Dealership told me that all Tiguans are having a issue with the sos and the info center freezing. They showed me it was in the system, but no fix. So I was sold a car they knew had issues that could not be resolved right now. As a consumer I should have been told the issues so I could make a decision to buy or not. I called vw from the dealership 4/24 and was told I would get a call back. I have called and called trying to call the case manager with no avail. I have been told by vw only the case manager. Plug for phone charger almost fried my phone. Was so hot my phone turned off, turning off my navigation. So my phone was off, navigation off and sos button not working. I was on the road in the middle of nowhere going back to the dealership 6 hours away.

My 2018 Volkswagen Tiguan experienced a failure of the airbag control module caused by water intrusion through the hvac access area and failed seam seal tape at the cowl support. The dealership confirmed that water leaked through a factory seam, accumulated at the airbag module, and caused the module to fail. The airbag warning light is illuminated, and the system is inoperable. This failure matches the same defect pattern covered under Volkswagen’s recall campaigns for the atlas and atlas cross sport (water intrusion leading to airbag control module failure), but my VIN is not included. The root cause and safety implications are identical: water entering through a body seam/hvac area and compromising the airbag system. This is a safety?critical issue that disables the airbags and creates a risk of injury in a crash. I am requesting NHTSA review this defect for potential recall expansion. Dealership findings: • water present at airbag control module • water leaking through hvac access hole • failed seam seal tape at cowl support • water accumulation damaging the airbag module • cowl trim cracked and repaired • recommended replacement of airbag control module and seam sealing tape • estimated repair cost: $1,377 + tax safety concern: airbag system is disabled due to water intrusion from a factory seam. This creates a risk of injury or death in the event of a collision.

Travel assist option is controlled by a sensor in the steering wheel. There is no way to disable it. When the sensor malfunctions, it plays an extremely loud and repetitive beep that cannot be disabled. It’s extremely distracting while I drive and happens every 30-45 seconds.

The starter system failed & yes it is available for inspection. Others & my safety was put at risk, as the car shut off while I was driving. The gauges turned off, I could not see how fast I was going and the turning and brake lights did not work either, the radio & a/c all turned off. The problem has been reproduced while the vehicle is parked on hot days and in the winter when the the heater is on for a period of time. There are online forums of other Volkswagen owners having the same issue. Volkswagen owners have had the ignition switch replaced and the issue has not happened to them again. There were not any warnings or messages prior to the failure. The message that appears says, "please check the starter system. When the vehicle is parked in the shade it turns on fine. I have an appointment scheduled at my local Volkswagen service department to have the ignition switch replaced on my 2019 Volkswagen Tiguan. Please contact me ASAP, this should be a recall and any costs associated with it should be covered by Volkswagen as this is a common safety issue.

My 2026 Volkswagen Tiguan has repeatedly experienced a complete loss of motive power while driving in active traffic. The engine stalls without warning, forcing me to perform a manual reset in the middle of the road. The vehicle also has a severe defect where it independently engages the electronic parking brake or shifts itself into park during low-speed or turning maneuvers. This happens without any driver input and results in the car "slamming" to a violent stop. My safety and my baby’s safety are put at risk every time I start this car. The engine has stalled multiple times while I was in the middle of busy traffic, leaving us a "sitting duck" for a rear-end collision. There is no warning; the power just cuts out, and I’m left stranded trying to restart the car while other drivers swerve around us. When the car slams on the brakes or shifts itself into park while I’m moving, it feels like the car is fighting me for control. I can’t trust the vehicle to stay moving when it’s supposed to or stay in gear when I’m merging. It is a life-threatening defect that makes the car completely undrivable. Yes, the vehicle has been inspected twice by the authorized manufacturer dealership, pacific Volkswagen. They have documented the safety issues on repair orders #[xxx] and #[xxx]. During these inspections, the service department confirmed that the vehicle is unsafe to drive, yet they stated they could not find a diagnostic "code" to provide a permanent fix. No warning lamps or error messages appeared prior to the engine stalling in traffic. The loss of power is sudden and total. The only symptom that appeared was during parking maneuvers, where the dashboard would occasionally display "sensor restricted" followed by the car independently shifting into park or slamming on the brakes. These symptoms first appeared in March 2026, within the first 970 miles of operation. Information redacted pursuant to the freedom of information act (foia), 5 u. S. C. 552(b)(6).

The contact owns a 2025 Volkswagen Tiguan. The contact stated that twice while driving 50 mph, an unknown message was displayed, indicating that the vehicle was not detecting a passenger. The horn inadvertently beeped three times, and the vehicle stalled and lost steering and braking functionality. The vehicle was restarted each time. On the second occasion, the vehicle was taken to an independent mechanic; however, the failure could not be duplicated. The vehicle was then towed to be diagnosed by the dealer, and the contact was informed that her hands might have been off the steering wheel, causing the vehicle to turn off. The vehicle was taken to another independent mechanic where it was determined that the steering wheel assembly needed to be replaced due to an electrical charge from skin to confirm that both hands were on the steering wheel. However, in the event that both hands were not on the steering wheel, the system would activate a fault code, and the vehicle might stall. The vehicle was not repaired. The manufacturer was notified of the failure. The failure mileage was approximately 6,000.

When it is hot out, while I am driving the car will say "pull over, shutting down" and then it says "please check the starter system. " the car will just shut off this was soo dangerous. This happened on the highway, with my two kids in the car and nothing worked. Everything black and my blinkers and lights werent working and just stopped in the middle of the street and wouldn't turn on. Very unsafe I am bringing it in to the dealership but they do not think it is that. It quickly flashed and then just shut off this has happened numerous amount of time-- only when its hot out. The first occurrence was last summer but now that its hot out again, happened today 3/9/26 I see that there was a recall for this of my car and my year but nothing on my VIN.

In warm weather, the car will start but immediately shut off with warning check starter system. All electrical will go off including brake lights, signal, a/c.

Relates to the Volkswagen recall: 28h7-ignition switch that for some reason is only applied to jetta's but needs to be expanded to include 2019 Tiguans . In vehicles equipped with a conventional ignition switch, the polyfuse can fail, particularly when the vehicle is operated in high temperature environments. If the polyfuse fails, it can result in the engine stalling while driving and failure of the vehicle's electrical system, increasing the risk of a crash. I have had this issue happen over 5 times since the initial incident last week. Now anything above 70 degrees fahrenheit causes the interior to "lose power" but the engine will continue to run. The a/c, infotainment system, all the adas, instrument cluster, headlights, and turn signals shuts off completely. No brake lights, no blinkers, no odometer reading, nothing. I can still drive (accelerate & brake) when this is happening but without all of those systems working I cannot safely operate this vehicle.

The instrument cluster became blank suddenly and no longer displays any speed, mileage, temperature or any essential information. It is currently available for inspection. This is a safety issue as I don’t have any speedometer reading or any important vehicle information. This issue occurred without warning.

I had a warning light for lane assist not working that would ding constantly. Dealer said known issue. Replaced steering wheel. Now I’m out of warranty at 59000 miles and it needs another steering wheel. They did not fix the issue. It is part of the airbag system and I’m worried about the lane assist which I can’t turn off might go haywire and make vehicle swerve itself into other cars.

While driving at road speed, the vehicle unexpectedly shifted itself into neutral (n) without driver input. The engine continued running, but the vehicle lost drive power. Simultaneously, the dashboard displayed multiple warning indicators including: “exhaust system malfunction” warning semi-automated driving assistance warning sos / emergency system warning the driver safely pulled to the roadside and turned the vehicle off. Upon first restart, the vehicle would not shift into drive. After turning the vehicle off again and waiting approximately 30 seconds, it restarted and allowed drive engagement. The “exhaust system malfunction” warning remained illuminated for the remainder of the trip. The vehicle was taken to a Volkswagen dealer. The dealer was unable to duplicate the condition after a 50-mile drive. Dealer reported only a rear radar fault code and stated no other diagnostic trouble codes were stored. Warning lights had cleared by the time of inspection. This was an unintended transmission disengagement event while in motion. The loss of drive power at speed presents a safety hazard. The vehicle is a 2025 Volkswagen Tiguan built mid-2025 and currently has approximately 1000 miles.
