2015 KIA OPTIMA Complaints

At or around 66k miles my vehicle stalled then shut off in traffic. No warning or signals. My vehicle went into limp mode. KSDS Knock sensor campaign installed prior. Oil had been consuming at a abnormal rate causing me to do oil changes more frequently and in between changes adding oil. Towed it to dealership because I was told as long as I had the KSDS update and maintenance records of which I did myself because it became expensive and records show on Carfax. After dealer mechanic looked at vehicle said I needed a new engine and Kia Corporate denied my claim claiming it was neglect which is absolutely untrue! They didn't even accept my records although on Carfax. With only 66k miles and being denied my vehicle sits worthless because Kia won't honor its warranty or recall. I even purchased gap insurance originally totally lost of money. I'm afraid my vehicle will catch on fire as it's been sitting for several months in my driveway.

after completing a routine oil change earlier in the day, the engine seized and the car had to be towed. When contacting Kia I was told their was a recall and if the knock sensor wasn't installed we are responsible. I communicated that we were unaware of a recall and were never notified of one as we are the 2nd owners of the vehicle. I later received in the mail a re-issue of what they claim to have sent out originally and was instructed to take the car to the nearest Kia dealer where they have since denied the repairs.

On December 14 2022 I had my oil changed at a service center. On December 14 2022 later in the day after the oil change service had been completed my vehicle vehicle began to sputter then stalled while driving down the road almost creating an accident. There were no warning lamps messages or other symptoms prior to stalling on the road. As the vehicle began sputtering and stalling the warning lamps then became illuminated. I coasted my vehicle to safety and parked it. I scheduled the first available appointment with a Kia dealership and had it towed in. They did an inspection completed a recall and said I needed a whole new engine and only the short block was covered. I have service records for regular maintenance. I have contact the dealership and manufacturer with a response that the engine replacement is not currently covered at this time. I believe that if the vehicle was at a higher speed or more traffic was present that the engine failure could have caused serious injury or fatalities. My vehicle is available for inspection if requested. My vehicle is still located at the Kia dealership. I currently do not have an invoice or paper receipt from them. I do have an email from the dealership stating a new engine cost before taxes. I am unable to upload the file on this page for some reason. I can make it available if needed.
