I have a 2014 Kia Optima that I purchased 3 years ago. My car lost all power on the highway and the motor is making a knocking noise I've taken it to my Kia dealer who always does my oil changes and they are saying that I need a new motor but no recalls are falling U see my VIN in their paperwork. Everything is always up to date on my vehicle oil changes to detailing once a week and this happens out of no where but my insurance states that under my VIN I have 2 recalls one for the motor and my Kia dealer is refusing to check or replace it after my complaint I have contacted Kia 1-800 number and they have also stated that I have a lifetime warranty on my motor and that I have in fact 2 recalls on my vehicle that I should take it into the nearest Kia dealer but I have done that and they denied

I took my car in after smelling fuel and they said there was a tear in my fuel line and it needed to be replaced. My car was included in the recall but Kia would not pay for the repairs because when they previously reviewed for recall issues they said there was no issues found. I attempted to contact Kia and they did not get back to me.

The contact owns a 2014 Kia Optima. When the vehicle was first started, a knocking sound emerged from the engine compartment. There were no warning indicators illuminated. The vehicle was taken to an independent mechanic who determined that an attachment to the fuel line was fractured and needed to be replaced. The manufacturer was notified of the failure and stated that the VIN was not included in NHTSA campaign number: 18V097000 (fuel system gasoline, engine). The vehicle was not repaired. The approximate failure mileage was 75,000.

Optima

My car (2014 Kia Optima) started having a faint gas smell about two days ago, I thought the gas smell was because I had gotten gas and some was on my shoe. I found out today that my direct injection fuel pump on the engine is the problem. The guy at the shop said the car could have blown up at anytime, and that I was blessed. I called the Kia dealership because the engine locked up on me in September of 2017. The dealership told me they replaced a part, but is now telling me they replaced the entire engine. The problem that the car is having now is not under a recall. I don't feel safe in my car because this is the second time something tragic could have happened due to something that was not my fault. I am sending this to warn other Kia drivers to be careful.

The problem is sporadic but happens frequently. If I press the gas pedal to increase my speed, whether from a stopped position, or to pull into a busy roadway, or to increase my speed to pass another vehicle, the car will start to go then choke, so that no matter how hard I press the gas pedal, the RPM stay the same and the vehicle loses power and will not speed up. If Kia doesn't figure out what is causing this - because I have seen other people with different Optima vehicle years complain about this - someone is going to get killed. I have had numerous near misses because of this problem. I also see many people saying Kia is telling them this is the way the vehicle is supposed to behave - really"?? my car is currently at the dealer to hopefully have the problem diagnosed and fixed. They gave me a loaner car, which is a 2013 Kia Optima, and guess what" pulling out of the dealership in the loaner I was almost rear ended because the loaner also has this problem, but 10 times worse than my car. It happened at least 30 times between the dealer and where I work - about a 30 minute drive. Always when speed needs to be increased by way of the gears needing to upshift. Please please please someone pay attention to this - I hope Kia isn't waiting for someone to get killed before they look into this failure that is happening that their dealerships are writing off as normal function! just as I was ready to submit this complaint, my dealership called me back and surprise: "we are unable to duplicate the problem" and "no problem codes were detected." Please Kia, take notice of this problem before someone gets killed!!!

I was in a parking structure, stopped at a stop sign. I continued a few feet to my designated parking stall and when I turned the wheel the car accelerated at what felt and sounded like full throttle on it's own. The surge of the vehicle forced the car to crash into a concrete wall causing extensive damage to the vehicle and bodily injury to myself. The vehicle is only a few months old. This car has some very serious safety issues. Someone could have been killed. Now I am terrified to ever drive it again.
