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.

Number 3 Fuel Injector, burning oil and have no idea where its going, gas mileage affected, VCT solenoid

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,
