The complaint is in regards the acceleration from either a rolling slow or from a stop to merge into traffic or open lane next to you on the freeway. when you need accelerate i'm getting a severe lag or noresponse from the accelerator. in the last two weeks i've had two occasions where i needed some quick acceleration in order to avoid a bad situation and the car just basically didn't accelerate causing the other drivers to have to brake in order to avoid a near collision. i've been complaining about this issue with this car now since i purchased it. took the car to the dealership and had one of the service techs drive with me said well it was in the eco-mode so you can expect that but i'm here to tell you that it is unacceptable that when you push on accelerator the car dangerously hesitates and is going to get somebody badly injured. so today it happened to me again on northbound i-5 in tacoma, wa, i was trying to get into another lane in stop and go traffic i had accelerate quickly the car just severely hesitated for 1-2 seconds and did nothing??. after this incident i drove the car directly to the hyundai dealership in renton washington and told them that i would not drive the car anymore until somebody looked at it that there was a severe safety issue and that somebody was going to get hurt badly. it appears that many people are having the same issue.. i have a 2018 hyundai santa fe ultimate 2.0 all wheel drive. i tried testing it in sport mode to see if the performance would be a little bit better and it did also hesitate in the sport mode as well. when you punch the accelerator from a creeping speed or a rolling in slow traffic and wanting to accelerate to a different lane or coming out of a parking lot onto oncoming traffic is really when you notice issue. this is a safety concern, please advise. thank you.
I was slowly crossing three traffic lanes and turning left. no one was coming from the right, so i applied the throttle in the inside lane and nothing happened. the car stalled without warning. it left me in the road and i was t-boned in the driver's door. the other driver was injured, and i have had neck issues. we could have both been killed. the car had stalled once before. i had the car two months with 2,400 miles and now it was declared totaled. i requested the black box to be removed and reviewed. it showed the speed and timing made sense, but why did the car not take off? i got the ticket - "failure to yield from a private drive". very, very frightening. i did not call the hyundai dealer to tell him about the crash until i had bought a new car of another brand. no more hyundai ever. the biomechanical engineer who read the black box requested i contact you after i fully explained the situation. if you need pdf files, i will have to figure out how to send them.
New car with less than 400 miles. i have experienced 7 episodes during the month of january, where the car fails to accelerate when turning onto a city street. this has happened with both right or left turns to enter traffic from a stop sign. it is just unresponsive for 1-2 seconds then engages with a bit of a jerk. very frightening! i've had a feeling of panic not knowing if the car will move forward as traffic is approaching. took to dealership where they checked for dtcs and computer updates. since the problem is unpredictably intermittent, the road test did not replicate the problem, and they returned the car saying it "drives as designed". there is definitely a safety issue that should be resolved before releasing the car. i have lost confidence in the car i had hoped would be safe and problem free.
