The 2016 Kia optima lx 1.6t has so many issues. First off, The power windows all stopped working within a week of each other. On the way home from work the check engine light came on and as I tried to accelerate the car started stuttering to go, it ended up jerking as if I was pressing the gas and then brake. I had to get it towed home. There has been oil spilling into other parts of the engine like the intercooler and the throttle body which could mix with gas which is a huge fire hazard. The high pressure fuel pump needs to be replaced. The car will no longer drive, the throttle position sensor needs to be replaced as well. The oil burns so fast, after a brand new oil change it doesn-??t even last a week. We have over 5 codes popping up when they did a scan and they are all misfires and fuel pump related.

I purchased a brand new 2016 Kia Optima and have been experiencing a really bad rattling noise that is coming from the motor. I have taken my car back and forth from the Kia dealership and each time they inspect my car, they tell me that they can-??t hear any rattling. As a mentioned earlier, the rattling noise is still there. I have been to the Kia in Durham, North Carolina and the Cary, North Carolina Kia dealership and still nothing has been done. I believe that my head gaskets or something like that in the more was defects when I purchased my vehicle. I also feel that the Kia dealership knew that my car had a defective motor and failed to inform me of that information. I would be glad to have my vehicle available for inspection upon request. How my safety and the safety of others are put at risk, is because the car could suddenly catch fire, it may stall in traffic, etc. The problem has not been reproduced or confirmed by a dealer or independent service center but I do know that something is wrong with my car and has been since I purchased it brand new in 2016. Kia Motors did a quick look at my car and stated that they heard not rattling noises coming from the car. Other than that no other component been inspected by the manufacturer, police, insurance representatives or others? There are no warning lamps, messages or other symptoms of the problem prior to the problem and it occurred over 2 months after I purchased the Kia Optima. If you are uncertain, simply state UNKNOWN, I am not sure as to why the vehicle rattles when taking off, but it is and have been loud enough for me to notice and my passengers as well. Therefore, I hope that this is something that you would look into and get some type of remediation. Thank You,

1 month after purchasing the car we noticed it was having oil consumption Problems. In December of 2022 we took the car in and were told by the kia dealership that the rings in the car were no good but when the issue was reported to our extended warranty the denied the repairs trying to say it is something else. This cars engines should have recalls on its engine just like all the other cars. We owe $20000 on a car that's engine is no good.

My 2016 kia is using a lot of oil I get a oil change and 100,000 miles later my oil light comes on and I have to put more oil in the car. I-??m told to check my oil every week an to get an oil changed every 150,000 miles. All my spark plugs have blown (I was told it-??s due to oil starvation) an my car started shaking real bad as I was driving. I was told to get spark plugs changed in order to get an oil changed and sometimes turned away twice because I had no oil in the car. Its not keeping enough oil in the car to keep it running smoothly which could cause a fire or even engine failure. I also noticed that there-??s a lot of smoke coming out of exhaust pipe when the car starts up in the back an that could be a problem one Macanic said. I was told to change my pvc valve to help with the increased oil consumption this didn-??t help but it was clogged up glad i changed it. This kia is starting to be to much money with me having to keep a 5 gallon oil bottle to ensure im never out of oil. Still making payments and keeping the thought in my mind that this kia could possibly break down with my child in the car. I need help with this fix I like the style an the look but the everyday drive and problems I can pass off on a Kia.

Knock sensor failure and misfiring

- Hamilton, NJ, USA

I had a catastrophic engineer failure that was reporting a DTC to replace the spark plug/ignition coil. This failure is miss mapped and had no previous Indicator warning the customer of a engine failure that would potentially leave the customer in an unsafe condition stranded. I had to have my vehicle towed in for service and the dealer informed that the vehicle needed a new intake valve. The intake valve failure at 118k miles is a little outside of warranty but still considerably young for an engine. There could be a number of reasons for this failure, material quality could make the valve brittle, manufacturing so the retainers could not seat properly in the spring. All the reasons are not customer induced nor at the stage in engine life that would be appropriate. After reviewing the Kia main social media account and talking to several dealers this type of failure is not uncommon for this product line as early as 30k miles. I believe that the volume of failure is large enough population that Kia should investigate 1) the mapping of DTCs/Indicator warning to the customer and 2) the actual engine failure population is large enough it should be reviewed by the government.
