When the brake pedal is pressed on the brakes will grab. It snatches the car kinda hard. Also when you give the car gas it will hesitate and will not accelerate. Another with the gas is that you can be driving at a higher speed such as 45 to 55 or so and you press down the gas pedal like your going into passing gear and it will not accelerate it’s like it’s trying to stop. Feels like the car is gonna fall on down onto itself and it loses power.

•I’m not sure what failed, the car was parked. And yes it’s available for inspection. •I had just parked the car coming from work and at the time. If I was in the car any longer than 5 more minutes it possibly could’ve been catastrophic. • All I know as of right now is that 5 days ago, it was escalated and I received a case number and a case manager 3 days ago. •The car has not been inspected •not that I’ve noticed, the engine light was on a week before the accident occurred, after getting off of work and the car system said to check my breaks. I had someone take me home since my car was undrivable. And the next morning I was going to have it towed but everything was working properly. The engine light was gone.

While in park and driving the instrument panel will show, "Check Brake" and "Hybrid System Warning! Safely Stop and Do not Drive". This is accompanied by the engine not responding to the gas pedal. The brake pedal will also loose pressure and once pushed the brakes will lock up making a grinding noise. The problem has not been able to be duplicated by the dealer. However there are multiple forms and online communities dedicated to try to resolve this issue since it's so prevalent. This issue causes a major saftey hazard as the car comes to a grinding halt and does not respond to the driver. From online sources it seems the problem is prevalent across years and models and only tied to hybrid vehicles.

Car simply started for me after work this past Thursday @4 pm I dove down the street and for about 5 mins and had to turn around due to me leaving something at work. When I arrived back at work I parked and cut my car off as I normally do and when I returned to start it back up it never did. I have previously been having to add 5 quarts of oil frequently at least once or twice a month for the past 7 months since last year. Was told my car had an oil consumption problem by a previous mechanical shop last year. Noticed that these cars have recalls on them and that my car and year do fit the requirements. I do owned my car with the Title in hand. It’s NOT a salvaged title. I have a service appointment on the 24th of June next Tuesday at Kia of Gastonia located in Gastonia, NC. I have to get my car towed to this establishment on Monday or the morning of my appointment. I’m asking that this situation can be properly investigated and properly and honestly handled under KIA policy. My name is [XXX] my # is [XXX] thanks INFORMATION REDACTED PURSUANT TO THE FREEDOM OF INFORMATION ACT (FOIA), 5 U.S.C. 552(B)(6)
