Engine has no leaks but is consuming oil at an alarming rate. Oil must be added every 3 weeks

- Jacksonville, FL, USA

We're experience excessive oil burning. The oil is not leaking. Internet searches have led me to many others complaining of the same issue. The engine is at risk of seizing. This can cause accidents if it happens on the road and expensive damage to the engine. We get the low oil indicator lamp and we check the oil levels, it's a good quart or so low. I don't believe we're even getting 1000 miles before the lamp comes on again. We do have the dipstick to tell us it's low. We have not yet had it to a shop for futher investigation to see if a sensor is involved or not, but our mechanics have said burning oil is a common issue.

We purchased car used on 11/27/19. Within 3 days it was chugging, engine light started blinking, and we were broke down on side of the road. Federico Kia in Wood River IL had us tow car to service and told us then that there was an issue with these engines and they would be -??replacing a part, and if it does this again, we would qualify for new engine. Would have been nice to know about issue with fires in engine prior to buying an 18000 car. After paying $400 for rental car they said it was fixed. Drove ok for another 9 months and then same thing happened yet this time we could smell something burning under hood. We were by dealership when this happened and due to it chugging and engine light, we took and dropped off again. We were then told spark plugs and needed oil change again after we had just changed ourselves 2 months prior. Said they were -??flushing out engine-??. Total cost was over $200 for us for oil change and flush. They said technically we were over our warranty time. SMH. It hasn-??t been right since we bought it. We can-??t afford to make their service dept rich, so we were told they would have to charge from them. We have had to replace same spark plugs 6 times as of today. We were just driving it after oil changes every 3 months even if miles driven were under 2000, and it-??s chugging again and smoke and smell from under hood again. This engine is going to catch fire i fear. I won-??t drive past 10 miles from my home because I have engine that chugs and overheats. Oil is not cheap and we put 2 qts in every 2 weeks or so. Dealership said there were no oil leaks they could see and yet puddle under car many times. Can someone please help us?

My name is E........ M........ and I'm writing this email/complaint in hopes it can be resolved or you can pass this email along to the appropriate person or persons to have this matter looked into. We purchased a used 2016 Kia Optima a few years back and have had nothing but trouble, from electrical issues, recalls, transmission issues, oil consumption, and smoke coming through the air vents!!!! and there's more, the last time we had an issue and took it to a dealer for problems shifting, hard shifts, loss of power, and smoking, we were told the dealer could not duplicate the problems while driving it and that was that, not a damn thing fixed because apparently everyone is stupid or blind and I was more than pissed. On 7/13/22 the car has been at the dealer again (for almost two weeks now, but they were so busy they just got to it today) so the car is there for the same exact things listed before only this time they state the turbo turbine is bad and it's gonna be $4000 to fix it. First off NO, and secondly NO, I will not let this happen! BTW, please pay close attention to the part of smoke coming through the air vents!!!! Currently, the car is at a KIA dealer still, the general manager was to call me on the 14th and NEVER DID today is the 19th, I called today and they are acting like they don't even know me. NO warning lamps, the car can be completely out of oil, and still no engine or oil light will come on. The fact that this car has smoke coming through the air vents is of most concern, I need help dealing with this issue and will contact a lawyer if needed or if you advise me to. BTW I emailed all head people at Kia corporate and NO response from them as well. Thank you The consumer stated the general manager has the approval to move forward with the repairs and would like to rescind the complaint.

- Troy, AL, USA

Using a qt or more of oil every 1000 miles or less. Kia told me that was normal. There are no puddles or spots where I park but it's obvious there's about problem. Has had plugs replaced 3 times in last year and today I had a flashing check engine light come on and lost power with a suspected misfire. Car will need to go to dealership again. I have lost all trust in Kia and their engines. With all these these problems there should be some kind of resolution to get these cars fixed at no charge. I currently have 112099 miles. I have been to the dealership many times prior to car going out of warranty with them telling my oil consumption was normal.

Purchased my 2016 Kia Optima EX om 10/20/20 with 82,000 miles and right away had issues with the car going into limp mode and check engine light on. Not knowing that there was already an oil issue, we took the car in to a repair shop where they told us the car was out of oil so they did an oil change. A few months later the check engine light was back on, so we took it back to the shop and diagnostics indicated an engine issue, so we took it to a Kia dealership. They had the car for 6 days then called and told us to pick up the car because it was running fine and the check engine light was no longer on. Check engine light came back on a few months later, took it back to Kia they said it needed spark plugs/wires and an engine cleaning which was $600. About 8 months later, the check engine light was back on, brought it back into Kia, they said we needed spark plugs/wires, transmission cleaning and break line cleaning, which was $450. 4 months later, got a regularly scheduled oil change, 10 days later, oil light came on and car was out of oil. Brought it to Kia, they did a combustion cleaning for $350. Did the 1000 mile test, which the car failed. Now Kia is saying I need a new engine which will be around $8500, and of course I'm no longer under warranty. My car has been using 6 qts of oil every 600 miles. Even if I could afford a new engine, I no longer trust the safety of my family in this vehicle. Plus there is no guarantee that a new engine wouldn't have this same issue. We are a one-car family, so this has also cost us in rental car fees and inconvenience. How has this engine not been recalled"?" Kia should do the right thing and take responsibility for this engine problem.

We have had numerous problems with the engine. There was a recall on these engines for 2011 - 2014 models. The problems have not been corrected. We've now been told we need a new engine. Do we have any recourse/relief since KIA continues to sell cars with engine problems" What can be done"

On May 30 2022 this incident happened. I have 160,000 miles on my 2016 Kia Optima Hybrid and was running just fine in the morning and later in the day motor seized up with no warning no lights from the dash. I heard while driving a quick squeal and puff of smoke from the belt breaking it was done. I was able to drive under the Electric motor side back to my house. I did not look under the hood until the next day and that is when I found the belt was broken. I did not know the motor has seized up until the dealership informed me and was told this motor is now discontinued.

- Kalamazoo, MI, USA

I purchased a used 2016 Kia Optima EX (89,000 miles) from a dealership in NC on March 12, 2022. On April 11, 2022, the car had to be towed to a Kia dealership due to misfiring. It turned out the sparkplugs needed to be replaced. The Kia dealership refused to cover any costs but the dealership I purchased the car from covered the bill. It was later confirmed that the oil was spilling into the sparkplugs. The car is burning/using oil at a rapid rate. I can confirm there are no leaks noticed under the car. I was told by a local mechanic as well as a service representative from Fred Anderson Kia of Raleigh that this is a known issue. The only way to fully fix this issue is to replace the engine but because the car is no longer under warranty, I'll need to pay to have a new engine installed in a car that I've had less than 3-months. I feel like this is a manufacturer's issue and should be considered a recall.
