Owner Complaints (6)
Purchased car about 4 months ago, before warranty ran out, the shop looked at it told me it was fine, it wouldn't accelerate. Few weeks later same issue but all my oil was gone, they found 11 things wrong with the vehicle, told me warranty wouldn't take care of it unless the engine blow up. The salesman Scottie Mitchell told me check Kia for recalls, called Kia 3 recalls, they were trying to finance another car higher, back wanted to know why the dealership didn't know about recalls, Kia place did call a Robert. One of the owners did know about recalls, why dealership didn't pass them on. They trying to sell me a higher vehicle to keep cover the cost of the one I got 1st
What component or system failed or malfunctioned, and is it available for inspection upon request? ******Speed Control- Vehicle will stall while on road/ highway causing rear vehicles to brake. How was your safety or the safety of others put at risk? *****Several times I was forced to pull over to side lanes to avoid being rear ended. *****Has the problem been reproduced or confirmed by a dealer or independent service center? I have called dealership several times in regards to this issue, all I was told was to do not use A/C or heater as that will make the vehicle lose power. Refused to conduct was full inspection of vehicle. Has the vehicle or component been inspected by the manufacturer, police, insurance representatives or others? *****No, no it has not been inspected Were there any warning lamps, messages or other symptoms of the problem prior to the failure, and when did they first appear? *****No warning lamps not symptoms of the problem prior to the failure.
Knock sensor detection system. Driving and all the sudden felt like it hard down shifted… car behind me almost hit me. Engine light started flashing so I pulled into autozone and plugged it in and got the knock sensor code. It’s had oil consumptions issues for a while. It’s so dangerous to drive with limited power and speed
-Knock Sensor Detection System - ECU Logic Improvement - I Was driving with my infant son in the backseat. I was going 70 mph when my car started rapidly losing speed. This happened again with just myself after receiving the car from mechanic. There was heavy traffic and I had to swerve to avoid being hit by an 18-wheeler. - I can see on the website where I received the car from, there is a recall for my exact make and model with the same code but they say there is no recall for my specific car. - The check engine light started flashing and Kia Systems starts talking.
Car smoking white , and driving slow after I hit a pothole when it was raining hard.
WHEN I GOT IN MY CAR THE CHECK ENGINE CAN ON. I STARTED DRIVING MY CAR TO WORK, BECAUSE I WAS NOT SURE WHY THIS LIGHT CAME ON BECAUSE THIS WAS/IS A NEW CAR. I HAVE LESS THAN 19K MILES ON MY CAR. AS I ATTEMPTED TO GET ON THE HIGHWAY THE CAR REFUSED TO SPEED UP. THE MAX THAT I COULD DRIVE WAS 60 MPH. I HAD TO PULL OVER TO THE SIDE OF THE ROAD BECAUSE MY CAR WOULD NOT PICK UP SPEED. SO I CALLED THE SERVICE DEPARTMENT, WHO INFORMED ME THAT WHEN I BROUGHT MY CAR IN FOR AN OIL CHANGE IN JANUARY THAT THEY HAS PLACE A SAFTEY FEATURE ON MY CAR TO KEEP THE ENGINE FROM BLOWING UP. ACCORDING TO THE DEALERSHIP, THERE IS POSSIBLY SOMETHING WRONG WITH THE ENGINE, HOWEVER, THEY ARE STARTING OUT BY CHANGING THE WIRING FIRST. I CAN NOT EXPLAIN HOW DIFFERENT THIS DRIVES SINCE THE WIRES HAVE BEEN CHANGED. IT IS THE WORST DRIVE. THE CAR IS VERY LOUD IT DOES NOT PICK UP SPEED WHEN IT SHOULD AND IT DOES NOT SLOW DOWN AS FAST AS IT USE TO. NEEDLESS TO SAY, I AM HAVING ISSUES WITH THIS CAR AND SEEMINGLY EVERY TIME I TAKE IT IN FOR REPAIRS, THE CAR GETS WORST. I WILL NEVER EVER BUY A NEW/USED KIA AGAIN.
