I took it to Kearny mesa kia and they told me it was the Knock sensor code P1326 I have looked and seen that there are plenty of recalls pertaining to this specific issue. Why are they telling me I have to pay for this when it is clearly something that is wrong with this on many vehicles across the board? I need my car fixed and back. Please help me.

I noticed my oil was not staying in the engine. Oil has been changed but seems not to retain. The car stalled out on February 2nd and would not restart. I believe it is seized. Noticed a very new and recent shake during braking days before it stalled. The fuel seems to show like 42 miles to go until empty but run out , i guess fuel pump or fuel float. Also a fuel smell. Also the digital service option does not work never a check engine light or anything .I've read many things by others who own same vehicle and had same issues. I purchased this car in August/September. I feel the dealer may have known of these issues and still sold the car.Please help me figure out how to address these issues to get it fixed.

Upon an engine light appearing I immediately turned the car around, and parked it at my fiancé's house. I had called kia and it was a little bit until I could take my car In. I had driven it over there which did ride a little rough. Informing kia of my issue they inspected it. I was told the second cylinder had melted which was caused by a spark plug. I do not understand how this happened, Kia said I am responsible for this and that they will not cover any repairs. As a result my car is junk and I am now left without a vehicle. I believed that it was caused due to the Theta II Class Action law suit as the only possibility for this happening is due to the fact that the car consumes large amounts of oil and constantly needs replenished. Which I believe is a direct cause, and high oil consumption is apart of the defect within the "Theta II Class Action." However they denied my claim.

Complaint Summary: I am the current owner of a 2014 Kia Optima, which is affected by recall 23V652 related to the Hydraulic Electronic Control Unit (HECU). The vehicle was imported to the UAE, and the recall was not addressed by the previous owner. As a result, I am now facing significant safety issues. Since taking ownership, I have encountered multiple engine problems, including sudden power loss, severe vibrations, and abnormal behavior from the throttle. These symptoms align with the issues outlined in the recall notice, indicating that the vehicle may pose a safety risk to me and other road users. Despite my efforts to diagnose the problems, I have already incurred costs exceeding 13 AED on various repairs and diagnostic services, all while being unaware of the existing recall. It was only recently that I discovered the recall information online, which has heightened my concern regarding the safety of my vehicle and the potential for further complications. Given these circumstances, I am requesting assistance from the NHTSA in resolving this recall issue and guidance on how to proceed with the necessary repairs while the vehicle is registered under my name in the UAE. It is crucial for me to ensure the safety of my vehicle for my own protection and for the safety of others on the road. I appreciate your attention to this urgent matter and look forward to any support you can provide. Please let me know if further information or documentation is needed Thanks alot

My engine locked up while driving down the interstate. I was almost hit twice because I was in the middle lane trying to get over and it was slowly giving out. I was able to barely make it to the side of the road and cut my car completely off. Once the car was off it would not crank back up. I had it towed to a local shop. He called me the next day to inform me my engine locked up but that I had a recall on my engine for this exact issue but I would have to take it to the local Kia. BEFORE I even had it towed there I called and spoke with Kia about my recalls. They stated they were still covered and I had an extended warranty on the engine recall. Kia gets the car.. a week later they call me to tell me it is NOT the engine and only the starter! YAY! Right? Wrong, another week passes and they now call to tell me they replaced the starter and now it is my engine that is the concern, it is completely locked up and the recall will not cover it. I called the local shop back and talked to the guy there that said it should 100% be covered and he did not see an issue with my starter when he looked at it 2 days before it was towed to Kia from his shop. I would not have put a starter on the car if they would have told me there could still be an issue with the engine. They actually stated it was not the engine in the call that I approved the starter to be replaced in. Now they are wanting to charger me for the engine and the starter which was put on my car under false pretenses. They have fully taking advantage of me and that I do not know much about cars but lucky I had someone else look at it that does know a lot about cars before taking it to Kia. Otherwise I wouldn't have known they were trying to scam me. It is awful!
