2015 KIA OPTIMA Complaints

Driving one day and I hear a knocking sound coming from the engine. It locked on me on the way home and isn’t drivable. Took it to the dealership and they said it had a recall and the engine needs to be replaced. Kia denied the engine replacement saying I took to long to come in. I bought it used and never received a letter in the mail about it.

The vehicles paint started peeling on one of the rear columns. I have noticed very many different Kia optimas with the same issue when it came to the same color paint. The paint is snow white pearl. I’ve had no success working with Kia and it is clearly a defective paint issue. I own several cars older and they never had issues. They are unwilling to help.

2015 Kia Optima began to not accelerate on freeway when trying to reach 2 rpms. Took for diagnostic it was stated solenoid needed replaced. However, the engine was knocking and I was informed that I needed a new engine. Mechanic did not want me to invest money into vehicle. I pulled up vehicle and see this as an issue for 2015 Kia Optimas. That current issues have been reported by numerous people. My car had no lights or warning sensors regarding these issues. Now the engine is inoperable and I have no vehicle w a car payment.

Vehicle lost power steering completely. Has been inspected. Steering wheel sensor needs to be replaced. ABS light active as well as steering wheel light. No reason as to why this happen but it seems to be and ongoing issue for Kia Optima owners after reading other reports online.

Have a white pearl paint that is completely chipping off by the pillars, windshield sides, top of the trunk, roof, around the gas tank and some car door edges. Have read an excessive amount of kias with MAJOR white paint job problems. It is also obvious the paint is thin as water which is contributing to this issue.

The contact owns a 2015 Kia Optima. The contact stated while driving at 35 MPH, smoke was coming inside the vehicle. The contact had to stop the vehicle and turn off the vehicle, when the contact restarted the vehicle, he saw flames coming from the windshield wipers. While opening the hood of the vehicle to see where the flames were coming from, the contact burned his hands. Medical attention was not required. The vehicle burst into flames. The fire department was able to extinguish the fire. The vehicle was towed to a repair facility. The vehicle was not diagnosed or repaired. The manufacturer was not notified of the failure. The failure mileage was 95,000. The VIN was not available.

While driving on the freeway vehicle began to knock. Pulled off the freeway into a dealership. Dealer said there was little oil in the engine despite having an oil change less than 1000 miles prior. Engine burned through 5 quarts in less than 1000 miles. No oil lights or check engine lights on causing engine failure and need for a new engine. Told vin does not fall under the endings oil consumption recall of similar model/year.

2015 Kia Optima Hybrid HEV system. Months after purchasing the vehicle two different lights would come on the engine. One is the HEV warning light and the other is a flashing “Turn off engine and check HEV system”. The first time it happened the vehicle turned off. It was towed to Kia, 02/2020. They change some sensor and sent me on my way. 3 weeks later the HEV warning light came on again so it was towed to Kia for the 2nd time, 03/2020. This time they said they could not recreate the issue. A month later the light came on again and again but since the light never stayed on, I kept getting told by Kia that I’d have to take it in when the light stayed on. 01/2021 the light came on again, with the flashing warning and the vehicle turned off, mid-drive. It was towed to a mechanic shop near me, where they replaced the wiring harness completely, but a month later the same light came on again. Over the course of the year, the warnings kept turning up and time and time I kept getting told they needed the light on at the dealer so they could determine with the codes, what is wrong. 07/2022, light came on as I was merging on to the freeway and the car shut off. I was able to make it turn on and make it home safe. The next day I towed it to the shop where they replaced the wiring harness and they stated they could not touch it further since the codes they got where “High voltage battery” codes and a specific tech is the only one when could work on it. I took it to Kia where it stayed 33 days. They changed a part. Two days later the HEV light came on again, so I took it back. They kept it one day, drove it 60 miles and they could not recreate the issue. I got it back on Saturday, 5 miles out the light came back again and again. I took video. Called Kia and now the car is back at the dealer while they try and figure out the issue. I’m scared for my life. The car gives no warning when it decides to shut off. Wheel locks on the times it does turn off. HEV system is no good.

Sunroof spontaneously shattered while driving down the road. The glass is pushing outward like it was broken from the inside of the car. Nothing hit the care at the time, there was a loud explosion sound and then cracking sounds after that.
