The car fails to respond to throttle. It does it randomly every one in a while. It's very dangerous. There are no check engine lights or anything. The car can run for weeks beautiful and all of a sudden you hit the gas and the car doesn't move. It can take 3-4 seconds before it responds.

It started shaking really bad out of no where, then wasn-??t going faster than 80 then down to 65 but wouldn-??t go more than 80 with my foot all the way on the gas. As soon as I made it to work tonight the car cut off. I got a jump the car was still shaking & wouldn-??t stay on if I let my foot off of the gas. I started it again without the cables but it cut right back off. I saw on cars.com it-??s a recall for the similar thing, number Sc172. I have been having fuel leaks for a while and had my knock sensor replaced from a previous recall. Now I have no way home.

Car purchased in 11/2022 with roughly 60,000 miles. I have owned the car for about 11 months. When we took the car for its first oil change there was no oil registering on the dipstick. The engine began knocking before the second oil change was due and after checking the oil I needed to aff 4.5 quarts of oil. I took the car to my mechanic was informed that there was no oil leak and that KIA engines were known for oil consumption and engine failure. He recommended I take the car to a dealership. I spoke with KIA corporate at this point and they said the car needed an oil consumption test before they would possibly help me. I scheduled an appointment at a Kia dealer for the test and when I took the car on 10/26/2023. They started it and refused to do the oil consumption test stating that the engine was ruined and it wasn't safe to drive. They quoted me nearly $10,000 to replace the engine, and stated that while other 2016 Optimas were covered under a recall for the exact same problem, my car is not covered under the recall and is not warranted therefore they will not help me. I paid over $15,000 for this car 11 months ago and it is nearly worthless, with a 10K repair it is worth 10K.

The body shop later informed me that there is a recall for engine fire recently, but my year/make is not listedin the info obtained online. The car started stalling while driving down the off. Smoke started coming through the vents. I pulled over to the side of the highway. A passerby told me that the car was on fire. Called 911. To note I had just picked the car up from Jim marsh Kia for battery replacement and problems with steering after the car was stolen in July. I had no previous issues with my car other than routine maintenance which I have records for.

I most recently started noticing that my oil changes were not lasting at around 46,174 miles. I found this to unusual in a car with low mileage. I had to result to buying oil from a local store. The light indicator started coming on when ever I apply the brakes. When I checked my oil, it was completely dry. So I started monitoring the oil intake, even after I had oil changes at the dealership in which I mentioned that it appears to be taking in an excessive amount of oil. What I noticed was that I was adding oil every week. I did not detect any outward appearance of a leak. In addition, I experienced on several occasion what felt like the car was having a seizure. As soon as I filled up the gas tank. The car froze up, steering wheel would not move and the car was in drive but not accelerating. I immediately shut the engine off, then restarted the car. That seem to alleviate the problem for that time. It then got really bad, that it shook and was running rough as if it was falling apart. So I drove it the dealership, explained the two problems I had, running rough and a high level of oil being used in between oil changes. I was given a diagnosis on cylinders misfiring and needing spark plugs replacement, and ignition coils. Nothing about the oil issue. I was later told that would be an additional diagnosis charge to check. I asked about engine warranty and possible complaints or recalls, and was told that my issues would not be covered under the warranty. I purchased the items they indicated needed to be addressed and took my car to someone else. That's where it was discovered, when the spark plugs were removed, that oil was sitting in each pocket or cup that holds the spark plugs. All of them were soaked in oil. Though the spark plugs have been replaced and the rough shaking of the car has subsided, the acceleration is still questionable and I'm still having to fill my car with oil weekly. I'm not due for oil change until 51,174 miles and I'm currently at 51, 098.

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.

- Killeen, TX, USA

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.
