We purchased our 2018 Tiguan in January of this year from momentum Volkswagen of clear lake. Our car has been in 3 times for service and each time (at 5k, 10k, and 15 miles), I have explained to the service writers that my car has a lag, a stop in the throttle and turbo, where it fails to accelerate immediately upon pushing the gas pedal. This delay / hesitation / and all out stalling is placing me in very dangerous situations while driving. Twice in the last week, it has completely stalled (engine does not shut off but car will not go) where I was almost rear-ended on the freeway in one occasion and almost t-boned in an intersection in the other. The folks at the dealership explained this is a �known characteristic of this vehicle�. Not one time, when I was purchasing this vehicle was it explained to me that the Tiguan would fail to accelerate and put me in such a dangerous position. I have reported this to vw and my local news media. I find it absurd that this is a known characteristic of the vehicle and not once was this mentioned as the reason until my third visit at 15,000 miles where the depreciation of my vehicle makes it a total loss for me to try to even get a safer vehicle. Why in world, has this known failure of acceleration not been repaired in anyway?.
