We purchased this car brand new and we have had to replace the engine and starter twice due to oil leaking through exhaust. No oil leaks on ground were visible. No lights warning low oil. Both time car broke down on road. About two years apart. We replaced parts with used motors as that's what we could afford.

Engine light just started flashing and no acceleration whatsoever. Takes forever just to get up to 30 mph. Called Kia and was told they don't know if there's a recall or not on that year. Not helpful at all. I'm afraid for my daughter to even drive it now and it's her only form of transportation to work.

Engine caught fire! had picked the Kia Optima up the day before from the dealership, where they had installed a new engine, belts, and hoses. Had driven 40 minutes for a doctor appt. Got off the freeway. As I was approaching the light (about 3 blocks from freeway), noticed gray smoke coming from under hood on passenger side. With a broken left arm, had to get out and across traffic. Saw the flames as I was crossing the street. In under a minute, the front of car was engulfed in flames.

While driving on the expressway, the car made a noise and the gas wouldn't give the car power. I pulled over to the side and while doing so the car shut off. After having it towed to the mechanic they said it is a seized engine. This is the second Kia that this has happened to!!

My 2015 Kia Optima sxl turbo is making a knocking sound when I hit the gas. It also stalled on me while at a stop light. Solenoid also had traces of metal shavings.

I have a 2015 Kia Optima. The engine has a delayed acceleration when taking off. Makes a strange noise when turning. Smells like it is burning oil after driving a short period of time and there is an excessive need to replenish the engine oil. Oil is extremely dark. Sometimes there is white smoke coming from the exhaust. Hard to accelerate on the freeway at times.

My daughter was driving down main street when everything shut off, electrical, motor, steering wheel locked up. She coasted to the side of the road, a man pulled over to help her after 20 mins the car was as able to start again. 3rd time this has happened. Very scary.

I was headed from Ohio to Michigan and all of a sudden it won't let me accelerate anymore and I get this burning smell and then all the dash lights start flashing and then the car just completely stops I pop the hood open on the side of the road and it's leaking oil which is not my fault cause I just got the oil changed and then the car just refuses to start now I can get the lights on and stuff but as for the engine turning over it's just not gonna happen and I'm surprised Kia hasn't had a recall on anything at all for these engines cause there are so many complaints about them

- New Brighton, PA, USA

Excessive oil consumption. No visible leaks, took to the dealer once and they replaced the PCV valve. Since that point the car uses a quart within a weeks time. No leaks, no smoke. Used for ordinary everyday highway driving. 40 miles a day round trip

While in in motion on the highway my car completed stop accelerating, (while pressing on the gas it was not going anywhere and then my engine light started blinking I pulled over and the car would not start up again. Then it finally did 20 minute later but the gas would not accelerate more that 55 mph and it shut off and would not start back up, I get my regular maintenance on time my car not even two years old and I took it to a shop apparently my engine has ceased up due to the luminal blocks. Now that is 6300 dollars and my car was just fine and I have previously discovered on line that my Kia Optima was not the first to have this happen.

About a week ago I was stopped at a stop sign and when I went to accelerate the car stalled for around 5-6 seconds then drove fine. Ever since then it will randomly feel like it hesitates while in motion driving between 45-65 mph.

My car a 2015 Kia Optima LX 2.4 gdi which only has 97,000 miles on it and while driving home this past Friday evening my engine started to knock really loud. Now the car is just setting at my house and when you start the car up, it still has a horrible knock. I can't drive the car.

Had my oil changed when supposed to they advised my car was almost on empty, after changed I hadn't drove it about 1,000 miles and I noticed it white smoke when I started it coming out of tail pipe, checked my oil and it was below the low level. I'm having to put oil in every few days and its supposed to be 2000 more miles til time to change it again. This has been happening about a month now, its not leaking oil, just burning it. Now while driving my car if I try to give it gas to accelerate my car starts losing power and a lot of white smoke comes out the pipe. Its still drivable as of now but this is obviously a huge issue with these make/models for the 2015's. I'm taking to a dealership next week to diagnose the problem
