2019 Volkswagen Tiguan

Car turns off while driving and says to check starter system when sitting in the sun, mechanics can not find anything wrong. Has happened twice in a two week period

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.

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.

Well driving on highway, front portion of sunroof shattered. Very loud, exploding sound.

Parking brake would not disengage and the shop told me it was because water was in the floor pan behind the passenger seat and it’s causing shorts In the electrical system. The cause of the water was diagnosed as a leaking sunroof. This has caused me loss of vehicle, time and too much money!

My 2019 Volkswagen Tiguan suddenly shut off on the highway with my children in the car. The vehicle lost all power, including steering, air conditioning, radio, navigation, and windows. I was barely able to coast to safety. The dealership diagnosed the issue as the ignition switch, part number 5Q1 905 865. This is the exact same part number included in Volkswagen’s current recall of nearly 50,000 Jettas for ignition switch failure. Despite this, VW has not expanded the recall to cover Tiguans. I paid over $700 for the repair, even though the part itself costs around $50. Worse, the dealership reinstalled the same recalled part number into my Tiguan, meaning the defect has not been corrected and could occur again at any time. This is a serious safety hazard. A sudden engine shutdown at highway speeds could easily result in injury or death. Volkswagen is fully aware of this defect but is refusing to extend the recall to affected Tiguan vehicles. I am requesting that NHTSA investigate this issue immediately and require Volkswagen to expand the ignition switch recall to include Tiguans equipped with part number 5Q1 905 865.

The contact owns a 2019 Volkswagen Tiguan. The contact stated that while driving approximately 68 MPH, there was a booming sound coming from the vehicle. The contact stopped to inspect the vehicle and discovered that the rear glass sunroof panel had shattered from the inside and shards of glass were ejected from the sunroof panel. The contact wrapped the roof with plastic to secure the damaged sections of the sunroof, to ensure no other glass shards fell from the vehicle while driving. The cause of the failure was not yet determined. The manufacturer and local dealer were notified of the failure, but no assistance was offered. The failure mileage was 44,000.

I am writing to bring to your attention a pressing safety concern regarding my 2019 Volkswagen Tiguan, with VIN [XXX] . Despite reaching out to Volkswagen of America on August 18th, 2025, and visiting my local dealership multiple times, the issue remains unresolved. The problem is with the gas pedal, which fails to accelerate properly when starting from a standstill, such as when reversing or driving from a traffic light or stop sign. This issue also occurs when attempting to merge onto a highway or freeway. The dealership has been unable to identify the cause, and the problem is becoming more frequent. I am extremely concerned for the safety of my family and other road users. I have attached a video recording of the issue, taken by my daughter on [XXX]. I urge Volkswagen to take immediate responsibility for providing a safe and reliable vehicle. I request that they provide a loaner car while my vehicle is under inspection. However, when I requested a loaner car from the dealership, they informed me that none were available and suggested that I rent a car instead. Unfortunately, I am unable to afford the cost of renting a car, especially for an indefinite period. I would appreciate your assistance in resolving this matter. Please find below the details of my previous correspondence with Volkswagen: - Initial complaint to Volkswagen of America: August 18th, 2025 - Visit to local dealership: August 14th, 2025 - Scheduled appointment: August 29th, 2025 Thank you for your attention to this matter. I look forward to a prompt response. Sincerely, [XXX] INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)

When it’s hot outside I get a warning about the starting system then all the electronics shut off including all dash, radio, and exterior lights

When trying to accelerate from a full stop the car is not accelerating when pressing the gas pedal. It happened at a stop light, I pressed the gas, the car went nowhere, pressed the gas harder until gas pedal was floored and then the car accelerates forward very quickly. Also happened when i was making a left turn crossing 2 lanes of traffic. Stepped off the gas to make a left turn, car begins to roll forward but when i press the gas nothing happens, I am now in both lanes of traffic flooring my gas pedal, nothing happens for about 5 seconds and the car lurches forward quickly. There are no lights illuminated on the dashboard. Brought car to VW delearship, they say they went over the entire car and found nothing wrong. When investigating online it seems others are also having the same issue and getting the same response from VW.

Experienced water leaks due to improperly routed sun roof drains. Experienced air bag electrical malfunctions, locking doors and unlocking doors, and air bag sensor/wiring harness inside passenger door.

My car has delayed acceleration issues of between 3 - 6 seconds. The last one that was 6 seconds ore more was on June 29. In addition it's happened several times. I took the vehicle in for its last service and was told the issue was my battery. Battery was replaced and issue not resolved. The service before that I was told it was a carbon build up. Continues to happen sporadically.

When the car is at a complete stop such as at a light or pulling onto a street, when you press the gas there will be a delay before it lurches forward. This becomes a very real safety risk trying to pull onto busy roads or even at lights. This car has been taken into multiple shops without it being fixed, the last one kept saying they had no idea why since there are no warning lights. They said they contacted VW who is saying a 5 second delay is within what they consider normal. It's not normal and is a very real risk and has almost caused us to get into numerous accidents.

Water pump leak/failure

High oil consumption

On three (3) separate occasions, my 2019 VW Tiguan has produced an error stating "Check Starter System" on the console and shut down electrical systems such as instrument panel, brake lights, headlights, taillights, back up camera, and other electrical systems while driving. All three (3) situations followed the same series of events whereas the car was out in the sunlight on warmer days (70+ degrees) and occurred within 5 or so minutes of starting. After shutting the vehicle off and attempting to restart, the ignition will not always work and the car will not turn over. When it does, the key will need to be turned farther than a normal ignition start and most likely produce an immediate error and electrical system shut down. In the most recent occurrence, I found a parking garage and left the car for around an hour and did not experience the issue for the rest of the trip. It appears that there was a recall for a similar issues with the Jetta models made in the same year (2019). Volkswagen Recall: 28H7-Ignition Switch / NHTSA campaign number: 23V604

My vehicle will have a slow start when I start the car and also a delay when it is at a stoplight. I took it in for service twice and they told me it was because I had an after market battery. However - yesterday my car completely went dead at a stop light and I had to turn the engine off and in. It often lags or stops at a light. According to Reddit it seems it’s a crank start issue.

Was driving on the freeway in my 2019 VW Tiguan when I experienced a sudden unexpected loss of power. Warning lights came on and the car went into a "limp mode" not allowing the engine to rev past a certain RPM. I took the car to be serviced at a local dealership where it was determined that the Fuel Injector Harness was faulty and needed to be replaced. When I informed the dealer that there was an extended warranty on the harness (2018-2019 model years within 10 years/120 miles) and the part should be covered, the dealer and later VW of America said that my vehicle was not part of the warranty. VW of America could not explain to my as why my car was not part of this warranty, but it is obviously a known problem on their end and they should honor what they advertised with their warranty extension with the NHTSA. [XXX] I find VW of America's response to this problem completely unacceptable and quite dangerous. Their unwillingness to take care of this critical component with a known failure rate unnecessarily costs consumers for repairs that VW should be honoring according to their own posted Warranty Extensions and could potentially cost bodily damage and lives.
