140000 miles motor will not start. Oil leak has been an issue and having to stick a quart of oil in every 1000 miles. Vehicle went into safe mode and wouldnt go faster than 35 mph. Then vehicle proceeded to cut off mid drive and will not start back.
Engine, Jul 8, 2022
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.

Car is at Kia dealership waiting from an approved from Kia manufacturer due to car having issues with oil in radiator and reservoir coolant, engine damage, car mileage is 91567 Location kia downtown Car unsafe to drive? I have complained to kia so many times and it looks like my records disappeared from ever getting to NHTSA or the manufacturer due to save money or not trying to fix the issue

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.

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.

Car was stolen off of the street. No alarm went off, keys were with my person. Back window was busted on the ground and all that was left. From video evidence, we can see that all it takes to steal a Kia is a screwdriver and a usb cord. Kia’s stolen are driven recklessly and harmfully to pedestrians (see #kiaboyz on tik tok or instagram). Problem has NOT been acknowledged by Kia or Hyundai. Insurance providers are aware of the situation.

Car has been burning an excessive amount of oil, first reported by my oil tech. Took to the dealership and they requested an oil consumption test, which I had to pay for. This is at 85000 miles. Drove for a little over a 1000 miles and returned it for a second round, the dealership said it had used a considerable amount of oil and would be escalated directly to the manufacturer. It has no leaks, smokes considerably, and hesitant upon acceleration. We will see where it goes from here, have been told that this is common in these vehicles. No oil light or check engine light ever came on. Just glad it didn’t lock up or blow up with my family in the car.

Four times in less than one year, car stutters, or stalls completely, check engine light flashes, and I have to maneuver to highway shoulder or slow lane to get towed. Very unsafe. Kia keeps it for a week , forces a software update repeatedly, sends me on my way and a few months later the sane thing again. Error codes always indicate engine knock amongst other things/an issue they know is theirs but “have to exhaust all options before they will approve replacement” according to service mgr. I have a car that I don’t feel safe driving because I drive alone and can’t trust it to get home home so I end up in the highway at 4am every time.

There is a known issue with this motor burning oil in the engine at an excessive rate. This caused my car to shut down on the California freeway from 65 mph. Warranty wont cover, dealership says its a manufacturer issue that is known and the manufacturer isn't replacing the problem engines. This is a life safety matter

My 2016 Kia Optima EX with the 2.4L GDI I4 engine has been ticking for roughly a year. The ticking coincides with acceleration (the harder you accelerate, the faster the tick). I took it my local Kia dealer where I've gotten my service done since purchasing the car. They simply stated, "these cars tick, don't worry about it." So I continued changing my oil regularly and monitoring it. Shortly after this, I noticed my oil levels would be lower than normal midway through an oil change cycle (I check my oil periodically because I do not trust the dealership). I took it back in with a concern and they did an oil consumption test, stating my car is burning excessive amounts of oil. After this service, the dealer said it "passed" and that it would no longer be an issue. Still, ticking persisted and I took it back in and forced them to do a full diagnostic on the vehicle (with a hefty charge on my part) to get to the root of the problem. They then recommended a valve deep cleaning service as the next step in the oil consumption service as my car was "still burning oil". There were never warning lights or any other cause of concern of a failure to indicate something was wrong. This is a HUGE issue with Kia and they will not accept the blame for manufacturing faulty engines. My car is no longer covered under warranty and the dealership states that if the engine blows from an oil consumption issue, Kia will not cover the cost. I expect Kia to issue a recall on these engines as hundreds of thousands of customers across the USA are experiencing the same issue.

Starting around 57,000 miles the engine started consuming excessive oil and occasionally experienced some knocking upon acceleration. I took it to the dealership and they put me on an oil consumption check every 1000 miles. After 3 rounds of checks they determined it was an issue with the GDI fuel system needing to be flushed which was performed by the dealership service department. The engine appeared to no longer consume excessive oil after I checked at about 1000 miles. After approximately 2000 miles, before my wife left for a long trip, I checked oil and it was down 1 quart. I topped off the oil and after about 750 miles, I checked the oil level and it was about 1 quart low again. The car is currently at the dealership and I'm told I will have to start the whole 1000 mile consumption check AGAIN! Based on other reports of engine seizing and fires I consider this a very possible hazard.

Over the last year I’ve noticed my car burning a lot of oil, around 1qt every 1000 miles. I’ve also noticed the transmission slipping some. I’ve checked thoroughly for leaks and have found none and the place that changes my oil has said they see no leaks also.

My car keeps running out of oil. I've taken it to kia and my mechanic. Both said I need a new engine. My car is hard to drive. I'm putting oil in my car after 200 miles because it's almost empty after having oil changes. I use 8 quarts of oil every time . My car drives horrible. I'm afraid it's gonna shut off on me when I'm driving and it's gonna cause an accident. I'm scared to drive it anymore and I owe 2 yrs left on it. I need a new engine and it's all been happening to my car after 1 yr of having it

The car engine suddenly started making a lot of noises, so we immediately pulled over and stopped the car. The engine wouldn't start back up, and started smoking. We had it towed to an independent service center, where they confirmed that the engine had a crack in it and would need to be replaced. There was still oil (we had just topped it off 1 week prior as it used a large amount of oil). There weren't any warning lights on until the same minute it started making noises, at which time the oil and engine light came on.
Power train, Engine, Mar 15, 2022
The engine is burning about a half a quarter of oil every 1000 miles. The transmission studers when trying to take off and sometimes lags when you accelerate harder.
