2019 Volkswagen Tiguan

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.

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 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.

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.

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

The contact owns a 2019 Volkswagen Tiguan. The contact stated that while his daughter was driving in extremely hot weather, the fault code message stating that the ignition was switched off, check the starter system, and to please pull over to the side of the road was displayed, while emitting a beeping sound to alarm the driver. The electrical systems, excluding the engine, became disabled. The contact stated that the headlights, taillights, instrument panel, and several other electrical functions were inoperable. The driver coasted to the side of the road and waited until the engine had cooled off before continuing to drive. The failure occurred consistently, in approximately 2 to 3 minutes, causing the driver to repeat the actions for the vehicle to operate as needed. The vehicle was taken to the dealer who was unable to determine the cause of the failure. The code starter fault error message was displayed; however, the dealer did not believe the failure was related to NHTSA Campaign Number: 23V60400 (Electrical System); however, the VIN was not included in the recall. The contact stated that the Part Number: 521905865; for the ignition switch, was the same and believed that the failure was related to the recall. The dealer was unable to duplicate the failure because the temperature was not 90 degrees or higher. The vehicle was not repaired. The manufacturer was informed of the failure. The failure mileage was 74,103.
