2019 KIA OPTIMA Vehicle Speed Control Problems

The contact owns a 2019 Kia Optima. The contact stated while driving at various speeds, the vehicle failed to immediately accelerate while depressing the accelerator pedal. There was no warning light illuminated. The vehicle was taken to the local dealer who was unable to duplicate the failure to determine the cause of the failure. The manufacturer was notified of the failure, but no assistance was provided. The failure mileage was 15,000.

This vehicle is a lemon. It is a 2019 with 81,000 miles. How in the world does the engine start knocking when i have consistently, kept up with the maintenance on this vehicle. If i do not hear something soon im weakening legal action. Since May 18TH i have been without a car.i am a single mom and this is so difficult. Mind you it was towed July 5th from where it broke down on me.

System failed to pick up speed.

Since I have had the vehicle I have had to have multiple Spark Plugs and Engine Coils replaced, literally every 4-6 months. One diagnosis said there was a problem with the motor, when I told Kia, they did not come back with the same diagnosis, well they sort of did, but did not noter it as an issue. Also, my car burns oil way too fast. I'm having to put in 2-23 quarts every 2-3 weeks. I have been told that the GDI motors are the culprit for this. Have even heard Hyundai had a enough complaints and has recalled the motor, but Kia did not, so we are still running around here paying excessive amounts on oil and repairs.

Breaks locked or failed and was forced off road into a ditch, car totalled

I WAS DRIVING UP A HILL AND AS I REACHED THE TOP OF THE INCLINE, MY CAR STOPPED ACCELERATING. I THEN ATTEMPTED TO USE MY BRAKES AND I BARELY TAPPED THEM, BUT THEY REACTED AS IF I SLAMMED ON MY BREAKS. I TOOK MY FOOT OFF OF THE BRAKES AND I BEGAN ROLLING BACKWARDS EVEN THOUGH MY CAR WAS STILL IN DRIVE. MY BRAKES WERE THEN LOCKED, I PUT MY CAR IN PARK AND THEN TURNED OFF & THEN BACK ON MY CAR WITHOUT REMOVING THE KEY. I THEN PUT MY CAR BACK INTO DRIVE, HOWEVER, MY GAS PEDAL WAS STILL NOT WORKING. I THEN TURNED MY CAR OFF AGAIN, REMOVED THE KEY, PUT THE KEY BACK, THEN RESTARTED AND WENT BACK INTO DRIVE AND IT BEGAN TO WORK AGAIN. THERE WAS NOT AN ISSUE AFTER THAT.

TL* THE CONTACT OWNS A 2019 KIA OPTIMA. THE CONTACT STATED THAT WHILE DRIVING AT 45 MPH AND MERGING ONTO THE HIGHWAY, THE VEHICLE STALLED WITHOUT WARNING. THE CONTACT PUMPED THE ACCELERATOR PEDAL SEVERAL TIMES AND THE VEHICLE RESPONDED. THE VEHICLE WAS NOT TAKEN TO BE DIAGNOSED NOR REPAIRED. NEITHER THE DEALER NOR THE MANUFACTURER WAS NOTIFIED OF THE FAILURE. THE APPROXIMATE FAILURE MILEAGE WAS 74,800.

IF I SLOW DOWN THEN SPEED UP IT TAKES OFF SLOW. IF I GO UP A HILL IT PUTTS AND WHEN I DRIVE IT JUST FEELS LIKE ITS PUTTERING THE WHOLE TIME. TOOK IT TO DEALERSHIP OF COURSE THEY DIDN'T FIND ANYTHING BUT THIS IS A NEW CAR I KNOW SOMETHING IS WRONG. I JUST GOT THE CAR IN MARCH DROVE FINE NO ACCIDENTS OR ANYTHING AND IT'S KIND OF DISAPPOINTING THAT MY CAR IS LIKE THIS BUT KNOW ONE KNOWS WHAT'S WRONG.
