Hi my 2015 Kia Optima on 08/07/2020 I put the recommended gas in my tank and then got onto the interstate after about 5-15 mins it started loosing power and I could no longer accelerate past 60. Also now when I start driving it jerks really bad and won't go past 2 on the rpms. When it jerks I'm assuming that it is the gears trying to change. Also my check engine has acted weird ever since buying this car it comes and goes and just recently is when it stayed on and when this happened it began flashing when the loss of power and couldn't accelerate properly issue began

've had nothing but problems with my car, first with my break light switch, then my A/C control panel went out. Now. As I was waiting for my food in the drive through lane my car engine turned off but my car was still on, I was able to turn my car off and get my engine going again.I also have an issue where my engine won't start but my car will turn on also when stopped at stop lights I often feel my car jitter a little. I had my battery checked but that wasn't the problem. I will be taking my car to the dealership to see what the issue is.

I was driving and out of nowhere the car started to bog down and the check engine light came on. It continued to do it every few seconds and was getting worse the whole way to the shop, which was the closest one I could find as soon as it started doing it. The shop ran the error code and got a knock sensor error. I had Kia come pick it up and take it to the shop. The shop performed a bearing clearance check and the vehicle did not pass so they replaced the engine and intake manifold due to "catastrophic failure". while replacing the engine they found the turbo had play and so they installed a new turbo assembly. After engine replacement they found the starter seized, they replaced the starter. After engine replacement they performed the ECU update and reset adaptive values, then performed wiring signal interference check which started ok. Immediately after getting the vehicle back from the shop I noticed a loud noise coming from front driver wheel area. Shop ended up replacing caliper and wheel bearings along with needing an alignment. All happened around 58K miles. Luckily still under warranty. Shop said it was just a bad engine. Nothing I could of done could of caused it.

Their is also lot of complain about this sound on youtube with Kia Optima customer with the same sound coming from the top of the dash board, when the engine is start.

I was driving down I25 around 530pm after work when all of a sudden my sliding sunroof glass exploded. There was no one around me at all thank god because the glass went everywhere and I didn't have my 10yr old son in the car as I usually do. Kia in motor city Colorado springs is where we bought it. This was our first low milage expensive car we have ever bought. Kia told us its not there problem and we must have hit a rock or something but this was false. As I hit nothing.

The antenna fin on my vehicle flew off at freeway speeds. Kia states it is not covered by the extended warranty. I have done research and have found 2014, some of 2015, and 2016 Kia Optima have been recalled for this reason. I have contacted Kia and they told me my vehicle was not part of the recall. The antenna fin on my vehicle has come off in the same manor as my of the vehicles reported and are a part of the recalls. I have attached a picture that shows the screws had been sheared off which you can see in the photo. This could have and may still cause a serious safety hazard to other drivers on the road.

I have a 2015 Kia Optima purchased in October 2017 with 34K miles approx. I am constantly putting oil in my car and it seems to evaporate in 2-3 days. There is no leak and we have no idea why the car is consuming so much oil. Lately the car has been knocking and when accelerating to merge onto highway, the vehicle starts to sputter and begins to stall. I do not feel safe in this vehicle with my children and no longer use this vehicle on a daily basis. After doing some research, I find that this year vehicle has the most overall consumer complaints and there still has yet to be a recall on the engine" I do not understand why Kia skipped this year?? let alone blame consumers that it's their fault for not following the maintenance schedule, yet when told the schedule has been followed, will find some other lame excuse so the manufacturer is not at fault. What is it going to take to have this engine recalled" we as consumers, myself, a single hard working parent, do not have the means to buy another vehicle just because Kia says it's not their fault. This problem started beginning of April 2019, my vehicle has 52K.

Was driving on the freeway at about 55 mph, got in lane 4 to exit the highway when my engine just turned off. I drifted to the side of the highway and tried to restart the engine. When I tried to restart the engine smoke started to come from the engine. Towed the vehicle to the dealership where they stated that they would call me with any updates (this was after telling me that it would cost $165 to diagnose). Just got the ECU updated approx. 6 months ago. No check engine light or anything popped up on the dash, just got the oil changed 06/15/2019. There are approx. 118K miles.
