I have a 2016kia optima EX and I had a problem with it. I used to take it to the Kia dealership for oil change and services. So recently I have done the transmission fluid and oil change.! After that I have weird transmission problems like it finding hard to accelerate and even when I am changing the gear from park to drive or reverse it makes weird noise like clutching. I spoke with the dealership and they say we have changed the transmission fluid then it shouldn-??t be the problem.! They don-??t even find the exact problem.! I have been spending a lot on my car. Kia is messing up with the recalls.!

I bought my car in 2016 brand new. It now has 47,000 miles on it. I took it in in 2018 to address a recall. I took it in 2019 when it had 19, 776 miles on it because of lack of power and they determined the VCMA motor was faulty. The car is now rattling and consuming oil extremely fast. An oil change is only lasting 2 weeks before I have to top it off. I-??ve had my spark plugs replaced. My mechanic (not Kia) has told me there may be an issue with the piston rings. The cost of repairing a car with less than 50,000 miles on it is getting ridiculous.

I bought my car in August of 2022 with roughly 66,000 miles on it. It now has 71,000 miles on it which per the manual would only needed one oil change. I-??ve had to do three and top off my oil every 500-700 miles with 1.5-2qt of oil each time. Which is way over the criteria for KIA-??s -??normal-?? oil consumption. This has caused my spark plugs to foul out costing me more money in repairs. I have only put 5,000 miles on this car in the whole year I have owned it.The oil consumption rate of this car is insane.

The engine was has blown twice the first day 95000 miles and again at under 6000 miles. And there is still a bad knock and major vibration and ticking noise coming from the car. We told the car we no longer have faith in this car and didn't want it no more and all he did was see if he could get us another loan to trade it in. We're now scared to really ride in to and can't get no one to help us on this my man is about to lose his job over this car

My car has been consuming oil and has locked up and will not operate. This issue has been reported to the manufacturer by several other customers, and my car is not a part of the recent recalls. This issue could have caused me serious harm, had I been on a highway, or busy intersection. My car engine now doesn't work.

Oil started leaking from the car and checking underneath it looked as though it was leaking from the plug so i replaced the plug, which did not fix the issue, and accidentally forgot to put the gasket back on. took it to the local shop was given a gasket and an oil change. the car started leaking oil worse than before so i took the car back. The oil pan had a little over an inch long crack on the corner/edge where the oil pan plug is. Mechanic told me he-??d never seen or heard of a steel oil pan cracking before. $400 for a new oil pan made from below par steel.

My 2016 Kia Optima has been consuming oil every 1.5months. I have multiple times had to replace my oil because my oil light kept coming on. I-??ve checked it every single time and it is barely anything there. I have my breaks mess up and not work as properly with my safety and others being comprised. I have brought this up to my Kia dealership but they have just brushed it off and charged me for an oil change. I have seen and heard many cases like mine and it has happened worse to them to the point where the car stops in the middle of the highway. My car has been checked by others and they have all noticed the same thing - the oil levels extremely low only after 1 and a half months or way prior to when my next oil change should be made. Having this happen is expensive and life threatening when the brakes don-??t work as they should or when my could possibly bust. I have received no help and would like to make this known.

The 2016 Optima SX Ltd is consuming oil, but no leak can be found by the mechanics. It is available for inspection upon request. Had the motor seized, I would have been stranded on the side of the road. I have all the CarFax Service records. It is serviced IAW Mfg recommendations. The oil light flickers and turns off at starting. A service engine in 30 days light came on. Took it to change the oil and there was NO oil in the vehicle. The oil and filter were changed, the engine cleaned and no leak could be detected. One week later the engine oil light flickered on and the oil was checked. It had consumed 1.5 quarts of oil in one week. There are zero oil stains in my driveway where the vehicle is parked every single day. This problem has been reported on multiple complaints NHTSA ID#s 11539081, 11538898, 11538679, 11538029...since August 1. Kia should issue a recall or investigate why the vehicles are consuming so much oil that leads to engine damage/failure with occupants stranded on the side of the road. Why is the oil light just flickering on and then off and not staying on if the oil is low? Please help.

There's an oil consumption problem... I'm burning through a quart of oil about every 300 miles. there are no leaks. Just burning the oil way too fast... There's been numerous people with this problem and no one has issued a recall... The car started doing this at around 60,000 miles. there's still plenty of life on this engine. It should in no way be burning this much oil... We need help. I was told it's part of an investigation already... We need this to be labeled a recall... This is not normal and thousands of people are having this problem with this model 2016 Kia Optima
