I just bought this 2017 Tucson limited a little over a week ago, have not even put gas in it yet, and I just had a scary experience of no acceleration from stop(s). Much as others have described it, when traffic light turned green I hit the pedal... to the floor and almost nothing (2mph)... about 5 seconds later it slowly began to rev into slow acceleration and I limped to the next traffic light and process repeated. As sitting motionless in a busy intersection is nerve racking, I just hope nobody would plow into me. I too regret this may be a hidden Hyundai issue, and have scheduled an appointment with dealer to try and address this safety issue, assuming they will reset computer.

We just purchased a 2017 Hyundai Tucson sport. The car has a serious issue of no acceleration after a stop, merging, passing on the highway and turning at an intersection. The car hesitates when you hit the accelerator, sometimes leaving you nearly stopped in a an intersection waiting for a car to hit you. If you choose to change lanes on a highway the car will hesitate when you press the accelerator to make the lane change. My wife has stopped driving the car due to the seriousness of no acceleration and safety concerns. We have taken the car back to the dealership and they said the diagnostics show that the car is fine and it is how the Hyundai transmission works in these vehicles. I think the car could be a "lemon." Not sure what to do.

The contact owns a 2017 Hyundai Tucson. While driving approximately 40 mph, the vehicle failed to accelerate and jerked rapidly. There were no warning indicators illuminated. The failure recurred several times. The vehicle was taken to the dealer, but was not diagnosed or repaired. The manufacturer was made aware of the failure. The failure mileage and VIN were not available.

Transmission does not consistently shift through gears. Under acceleration, it will sometimes shift from 1-2- neutral instead of going into 3rd gear. If you deaccelrate and then try to acelerate as when coming to a turn, the car has extreme hesitation and sometime will just rev to 3,000rpm without any movement...again like it is in neutral. Dealership says this is all by design and I should adjust my driving habits to accommodate this dangerously designed vehicle.
