I have taken my car in to the Hyundai dealer three times for service to and they have been unable to recreate the problem or diagnose the problem via a code. I had the transmission fluid replaced thinking that might originally be the problem. The car hesitates in lower gears when it is in ev mode and will rev at higher RPM before slamming into gear when it goes into gas engine mode. When coming off the highway and decelerating it will slam hard into gear as the car brakes and goes into ev mode. It is not consistent and every time the car is brought into the dealer they claim there is nothing worn with the car and they cannot duplicate the issue. When pulling out from a stop sign in ev mode there is absolutely no power some times and all of sudden the gas engine will kick in and accelerate. I have had other issues with the hybrid battery just shutting down on the highway so it concerns me that there is more of an issue that needs to be addressed.

While pulling into a busy intersection my car decided to dive out. The warning sign 'hybrid system warning /pull over safely and stop driving' 'check power charging' came on and my car came to a halt. I was pressing the gas but couldn't accelerate only cruise over to a parking lot. That is extremely dangerous had I been on the interstate and could have caused a terrible accident for a car to all of a sudden slow down and stop. All fluids are full and we can't deternine the source of this

The brake pedal and accelerator pedal are so close together as to interfere with each other. Specifically, as one comes to a stop, the brake pedal is so close to the accelerator both laterally and vertically, that the operators foot may hit both pedals at the same time just before coming to a stop, causing an unintended sudden acceleration. This is a significant safety issue for the driver, occupants, pedestrians and other vehicles or items in the path of the car. I have has 4 such incidents, one involving a rear end bump. The Hyundai dealer inspected the car for sudden acceleration and found nothing and dismissed the concern. Hyundai customer care representative erin thompson stated " I did not design the car, it operates as designed and there is nothing I can do for you". further, she stated "I will not say it again" when I tried to offer clarification of the issue. I believe this problem is a fundamental design defect in the car and violates the implied warranty of freedom of design and manufacturing defects and fitness of purpose. It may also not meet federal specifications for ergonomic considerations. Can you help? thank you the consumer requested a copy of the examiner's report.

The cruise control malfunctions, when you press the steering wheel controls it may stay on even though you hit cancel. If you hit the reduce speed button, it may cancel cruise control, speed it up, or reduce speed. Also, the airbag deployed notification randomly turns on. It appears that some wiring running on the top middle of the steering wheel, directly under the airbag, is crowded or just malfunctioning. This happens when the vehicle is in motion while attempting to set or engage the cruise control.

Car loses power when going into a turn and when driving long distance on open high way, sometimes it's like the car is applying breaks by it self, then just takes off like you have your foot full force on the gas puddle. Break lights and head lights go out every two months.

I was driving home from work on the highway, and approximately 40 minutes into the ride the car struggled to accelerate while I was driving on the highway at about 65-70mph without a warning light or any type of warning display on the dashboard. The car hesitated when I put my foot on the gas to pass another car, or if I slowed down in traffic, it struggled to accelerate above 20 - 40mph. When I reached my exit, and came to a stop light, the gas pedal was all the way to the floor just so I could get up enough speed to go across the light, as well as accelerate so the car in back on me could go as well. The engine would hesitate, and when it did finally reach the right speed it was still not a smooth ride. When I reached my destination, I turned the car off, and turned it back on about 2 hrs later. The car started (with a little hesitation in the engine), although it still struggled to accelerate past 20mph. It was also hesitating, and felt as though it would stall. I drove the car to my mechanic, about a 15 minute trip on local roads. There were a couple of uphill battles, where I could barely get the car up the hill. My mechanic checked to see if there were any codes from the computer, and the code came back as 'turbo under-boost'. the turbo charge is dead. I have a turbo charged engine. Therefore, since the turbo booster is dead, it basically leaves the engine without little power!

On April 18, 2016, while pulling into a handicapped parking spot, I was almost parked when the engine started roaring like it was revved up. My car went over the parking barrier and up the handicapped pole and over on hood of the car in front of me. I have been with my insurance company 39 years and I have never had an accident. I am a very safe driver. I am a truthful and responsible person.
