- low miles and still under all manufacturer's warranties. - engine will idle rough, vibrating the whole car while stationary. Dealer could not replicate. - engine acceleration is poor from standing, dangerous in city traffic. Dealer could not replicate. - engine will shut off while turning left in los angeles city traffic, car is completely without power. This is very dangerous in city traffic. Dealer could not replicate problem. Instead, dealership told me that engine is leaking oil. Bs. there are no oil drips in my parking space. Another mechanic told me that my car is not leaking oil. Dealership told me that they 'will work with me'. meaning they will let me pay for each visit but they will not honor their drivetrain warranty. Engine burns oil. Engine burns oil. A new car should not burn oil. - engine will sound like a sewing machine when driving from standing and turning the wheel. Dealer could not replicate problem. (this was likely due to engine burning oil, oil low; after refilling oil, engine will not make this sound.) - I now must check my oil level at all times before driving and refill oil to full mark on oil dip stick. Hate Kia. - car cabin is too hot to drive in. Metal ECU at bottom of steering column inside cabin is 180 degrees Fahrenheit. Dealer could not replicate the problem. Hate Kia.

While sitting idle for over 45 minutes the car started to vibrate. When I began to drive it shook and did not pick up as it should when driving. When stopped at a traffic light it vibrates worse. I called the dealership to schefule an appointment for January 4,2019 but received a call today (December 31, 3018)to reschedule for January 18,2019. I've researched the internet and found that there are others having the same problem. I am a little leery in driving the car since the dealership doesn't have loaners and I must continue with my day to day living. I am not driving on the interstate with this problem. Stated earlier

My car begins randomly shaking. I have had all maintenance done at the Kia dealership as per my warranty specifies. The last 4 weeks, my car will randomly shake violently while idle, attempting to accelerate in the different drive modes. Yesterday, June 21st, 2018, my car started shaking violently as I was parked at the food city in chattanooga on ooltewah ringgold road.I was on facebook video messenger with my friend eating a mcchicken. I dropped my sandwich and immediately popped the hood. Upon opening, I see the engine shaking violently as before. My friend witnessed it as well. I immediately called Kia motors customer service. They called roadside service to tow the car back to the dealership in cleveland, tn. Today, 6/22/2018, Kia claimed they were unable to duplicate the issue and blamed bad gas. Even though the shaking happened upon returning home. My car has continually done this even with me using shell, bp, or 100%gasoline. Kia refuses to give me a fair price for trading to another car. The engine also ticks. I asked about this at the time of purchase on Jan 13th, 2017 by the sales associate matt hake and was told it was normal, even though the ticking as intensified.

The vehicle is the S model, new for 2017, I have driven the car approximately 2,000 miles since leasing it in September 2016. The car has poor acceleration, especially going up hills and merging into traffic (moving, city). It hesitates at traffic signals (from a dead stop). The vehicle tends to sway side to side from time to time (moving, city), the vehicle is under warranty and has been looked at by two different Kia dealers. A technician has rode along with me; felt my concerns, but cannot duplicate it. I was told in March 2017 that the computer had been "tweaked", but no further information.
