2018 KIA OPTIMA Complaints

Excessive oil consumption 1-1.5 months approx. 1,000 miles into new oils change. It is available for inspection. Safety was put at risk due to not knowing there was no oil in my vehicle while constantly driving it as it did not display the oil warning sign on the dash board. The oil change dealership has confirmed an oil consumption issue two separate times. I am familiar with multiple people having this same issue with Kia and hyuandia vehicles. The dealership is requiring multiple steps to be paid out of pocket prior to using the full warranty i purchased to cover the issue even though they know what the issue is and how to fix it.

purchased my car in june of 2019. Ive scheduled regular oil changes and maintenance until june of 2020 where the engine light began to flicker and the car would shake. I took to Koons Kia owings mills md and it was repaired. Next year same thing. Oil compression issues all year round where i have to keep putting oil in. Now my car starts and shakes violently. the kia service modurator on the car indicated there were an engine issue. I cannot keep dishing money into this car with so many recalls (current fuel pump recall and anti theft issue) is also included. Please help

I'm reporting these issue pertaining to the engine within the first 3 weeks AFTER the engine replacement recall was serviced and completed. The vehicle was exhibiting the same defects and major health and safety hazards as before the new engine. Intermittent engine failure, even worse, while i was trying entering the hwy at speeds of 45-50 miles it jerked very violently and loss total power while vehicles were behind me nearly rear ended. Prior to this I reached out multiple times to have it serviced at again. The original service department didn't respond, so I called other service departments and was told it needed to be serviced by the original dealership/service department that replaced the engine. I had the vehicle in normal working conditions a few days before it began exhibiting the same problems as before the engine replacement. It was in operable condition but still stalling and refusing to crank unless primed, until it ultimately just would not crank at all and is back in the same condition it was before the new engine but it is not locked up currently. The time frame and Milage between first experiencing the issues to now, March 2023-64745 Started shuddering, loss of power while driving, but would crank right back up without issues. Happened a few times, charged up battery thinking is was am electrical issue. April 2023 More frequently the issues occurred, still same severity levels. May 2023 Began happening every time at an idle, whether I was at a fast food in drive through placing an order, or to wash the car. Every time at an idle this would happen, and would take a few times of trying to start the vehicle and after about 5 seconds of cranking it would catch and work. I began placing the vehicle in neutral while at idle and it would assist In the stalling out sometimes. After a few days of this it refused to crank due to the engine locking up. Milage at this time was 68048. Aug 2023-New engine, drove about 2k miles-70207 current

My vehicle is under a engine / oil consumption recall, I have contacted kia multiple time in regards to this issue as the vehicles are having engine fires due to this. I was advised by kia that my vehicle is under recall and has lifetime warranty but they will not fix or swap the motor until it goes out. This is a huge safety risk I am literally scared to drive my vehicle due to not knowing if the engine is going to go out at anytime or start on fire in the middle of the expressway.

The braking system "catches" at 13mph regularly. It feels like the brakes are being applied or the vehicle is downshifting when it is decelarating to around 13mph without any actual braking being manually applied. So far no safety risk, but if the brakes fail at any point for any reason, there will be potential for great risk. The local Kia dealer was able to reproduce this but had no explanation, no recommendation, and no further advice or assistance was offered. At this point, the Kia dealership is the only entity to inspect this issue. There are no warning lights or indicators of failure or problems, but this issue has been ongoing since the vehicle was purchased.

When we drive the car it hesitates as if it’s going to cut off and it keep burning oil. We have to put in at least 2-3 quarts in per week.

Was driving vehicle on freeway, around 65 mph, smooth road, no bumps, no indication of any road debris and suddenly heard a loud cracking/exploding noise which was extremely startling. After hearing some outside wind noise and the sound of glass pieces rattling, I realized that the glass panoramic sunroof must have broken somehow. Luckily I had the interior fabric shade closed, so no glass pieces entered the cabin to injure anyone. After getting out of the car, I could see around a 12 inch diameter hole in the sunroof glass. The remaining glass that was still attached was full of cracks. I have created a case with Kia Consumer Affairs and waiting to hear back from them. The vehicle has not received any outside inspection as of yet for this incident. There was no prior warning to this issue, no creaking noises or visible cracks.

MY ENGINE STARTED MAKING A HORRIBLE NOISE AND JUMPIMG. THE OIL WAS JUST CHANGED AND IS FINE. HAVING TO REPLACE ENGINE AND ONLY HAD CAR 2 MONTHS

Knock sensor detection system. Driving and all the sudden felt like it hard down shifted… car behind me almost hit me. Engine light started flashing so I pulled into autozone and plugged it in and got the knock sensor code. It’s had oil consumptions issues for a while. It’s so dangerous to drive with limited power and speed
