When accelerating from a stopped position, the car will sometimes not move forward or will sometimes surge forward at high speed or will at other times move forward but will do so in a jerky uncontrolled manner. Been trying to get the dealer to fix this but I'm told this condition is normal. There's no way this is normal! When pulling onto a busy highway I never know if the car will respond to acceleration of not move for several seconds. This car is dangerous and I feel that it's only a matter of time that I will be in an accident because of this condition.

The vehicle would start to move and then frequently stall (abruptly lose power) when accelerating to go from a stop. It was especially dangerous when making a left turn, as it would stall in the path of oncoming vehicles. It was also a serious safety problem when the car behind mine would accelerate to go, after it appeared I was moving, and would then need to take evasive action to not rear-end my car as it stalled momentarily. After stalling, the vehicle would either lunge forward suddenly, or I would have to release and quickly reapply the accelerator. I also experienced three occasions when the car would move forward while it was in reverse gear. Both of those issues also created some very scary close calls.

Transmission stutters and bucks on initial acceleration from a standing position with high variable revolutions and latent unintended acceleration resulting. Occasions of erratic forward motion occur at any speed when pedal is pressed but not always at same location of pedal stroke. A recent occurrence of loss of acceleration while turning left and merging into traffic lanes left the vehicle and occupant stationary and vulnerable for several seconds. There appears a progression of increasing frequency and severity to these events that I have reported to the dealership on several occasions, the latest being on 10/8/18. They stated they had been receiving or hearing of similar issues.

I am experiencing a problem with the vehicle's acceleration from a stop which is worsening over time. I bought the vehicle new in september 2017. I routinely experience a severe lag in acceleration from a stop, causing jerky movements and sometimes unintended acceleration. I do not feel as if the vehicle is safe to drive on a daily basis. I have had the car looked at by hyundai technicians in my local dealership's service department. They have reported that there are no issues they can identify and the car is operating as it was built to. I have expressed my concerns about the vehicle's safety and they have told me to contact hyundai's consumer affairs department. I have initiated a ticket with consumer affairs.

The 2017 tucson sport has the 1.6 turbo with the dual clutch transmission. When pulling out into traffic, one never knows if the car will respond to the gas pedal and accelerate or just stumble along. This is a known problem, and there is a recall or similar for the 2016 with the federal safety agency. The dealership (kearny mesa hyundai, san diego) tells us that "they all do that" when we took it in for safety concerns and repair. Any subsequent requests for repair were met with "it will cost you 150 dollars to check it out if it's the same situation as before with no solution". This car is a danger to us and others on the road. It also tends to go into some sort of leaf blower mode sometimes when you hit the brakes, where the revs soar but it doesn't act like it downshifted. This is not a mixup in brake/gas pedal usage, like the unintended acceleration problems weve all read about with other brands. The dct has a mind of it's own and is a hazard on the road. The problems are when the vehicle is in motion, and it can happen anywhere, at random, highway, freeway, pulling out of a driveway... Anywhere. Please help get these dangerous cars off the road. Not sure what documentation you want, but the car is under warranty, and was bought in aug 2017. Cars with this engine/trans are still for sale in the showrooms nationwide, a known danger to all concerned. The dealership service mgr has told us how there are a lot of unhappy customers out there with 1.6 turbo/dct drivetrains, and yet they are selling more by the day. Yet there is no support other than the one time attempt and "they all do that". Help.
