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.

- Harrison , TN, USA

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

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.

- San Francisco , CA, USA

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.

The main problem with the car is the error p1326 is the knock sensor. I have this car for almost 5 or 6 months. The error has never been inspected by any insurance or police. The only warning about this problem was the "engine light" on the car.

#1Headlights & break lights going out often. Bulbs can-??t be replaced anymore due to wiring burnt ( 1 headlight ) Took it in and they didn-??t even look at it. Have do Documents to back that up #2 Engine light coming on, diagnostic testing indicated spark plugs need to be replaced. Had to do this two times with oil on plugs Took it in and they NEVER look at the spark plugs #3 car burning excessive amount of oil anywhere from 1 quart a week to 3 1/2 quarts after driving 600 miles. Took it into the shop for oil consumption testing only to be told that their warranty would not cover it and it needs a new engine. I have a 10 year or 100,000 mile warranty on my car! and at the present time I only have 88496 miles on my car I have documentation to back up my claim, I have been a loyal Kia owner for 18 years and they have absolutely treated me horrible in regards to this saying that it was lack of maintenance and they never checked the issues that led up to their findings. They indicated that there was sludge in my engine but could never prove or show me anything that they did to document the sludge and trying to blame it on me. This car is a safety hazard as I am aware of mini other Kia optima-??s dad have either caught fire or repaired to have their motors replaced due to the same issues. Anything you can do to help me with this issue ! I-??m 60 years old and know how to take care of my car

- Louisville , KY, USA

In Sept the car oil light came on. The car was out of oil. Took it to shop and they could not find a leak. The car was filled with oil. Less than 1,000 miles later in Oct the same situation occurred again. The car was inspected an no leak was found but the oil was gone. In Dec after going 2 500 miles the same situation occurred again and another shop inspected and could not find out why. In all 3 situations the driver had to pull over immediately and be stranded until oil came.

My car has been burning oil and progressively got worse. The oil lamp light would only blink for a few seconds and turn off to indicate the oil tank was low. I would be around 3 quarts of oil low every 2,000 miles. I have taken my vehicle to the KIA dealership and started the process of a oil consumption test to build a case. After some maintenance work and coming due to check back with the dealer for the 3rd engine oil test, the engine light illuminated. I checked my oil level to make sure there was oil in there and after restarting my car the light turned off. 4 days later my car stalled when coming to a stop. After a few minutes I was able to power my car back on and drive it safely home. The car was taken to the Dealership I have been going to in San Bernardino. I let them know I had checked the oil dipstick after the engine light was on before the stall and they told me I would have to start the engine consumption test over for taking out the dipstick, altering the test. My car has been at the dealership for 4 days with no word on why my engine stalled but I can pick up my car today after they do an oil change to begin the oil consumption test again. They asked that I drive 1,000 miles and bring it back for a final check on the oil per KIA's instruction. In the meantime I have to hope that my car will not stall again possibly causing a wreck harming myself and others or that my engine will not fail before the 1,000 miles are up. If I make it to 1,000 I am hoping KIA will honor the powertrain warranty and fix the engine, but my hope is fading. Although a settlement for similar issues has been made in favor of KIA owners, my problems are occurring after the settlement date.

Misfire-?" oil on the spark plug caused misfire. check engine light came on. OBDII scanner show a P0302 trouble code. Eventually the engine misfired enough and lead to a backfire. This also led to Decreased Fuel Mileage, Catalytic Converter Damage, and Blue Exhaust Smoke.

I was driving the car on the high way when I suddenly heard a strange noise from the engine with a shake in the car then the car completely switched to the hybrid engine from the gas one. The hybrid battery was depleted within a minute or two but I was able to put the car on the side of the high was before it completely stopped moving. After that whenever I press on the gas pedal nothing happened there was zero propulsion. I took the car for inspection the hybrid battery was depleted so it got replaced but then the engine itself isn't working and apparently there is a metallic parts in the oil My car is available for inspection if needed It was definitely unsafe to break down in the middle of the highway I believe the normal non hybrid car had a recall issue with the engine and the hybrid has the exact gas engine the 2.4L one The car wasn't inspected yet by the dealership as it is hard to get an appointment The car had 2 codes before breaking they were P0014 and P0420 they appeared approximately 2 weeks before the incident
