2019 VOLKSWAGEN TIGUAN Complaints

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

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.

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

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.

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!

The contact owns a 2019 Volkswagen Tiguan. The contact stated that after a heavy rainstorm, approximately 4-inches of water was discovered in the rear driver’s side floor and on the rear driver’s side seat. Upon inspection, the contact discovered mold inside the vehicle due to the rainwater entering the vehicle. The contact stated that the failure was due to a faulty drainage from the sunroof. The cause of the failure was not determined. The manufacturer was not notified of the failure. The failure mileage was 69,000.

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.

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

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.
