    I just noticed that there is a weird creaking sound that sounds like its coming from the front left wheel as it turns (see video) I can really only notice it (hear it) at about 20-25mph and below. It seems to happen at the same spot because as i go faster it happens faster and as i go slower it...

    So this happened twice so far this week. I start car wait a min then drive off. I noticed the tranny not shifting and number 1 was displayed on the dash as if I had activated semi auto mode but it was in full auto mode. Flipped the shifter to the left and then back to auto which took care of the...

    Hi I've got a 2014 EX Plus, a month ago it started to miss and smoke (gry /white) when I really floored it. It's also using oil but not smoking during regular driving. I've changed the PVC valve, plugs, oil, all f which helped but the problem is still there, no codes stored although the check...

    Car is an '11 optima 2.0t. I never read the TPS before the BTR tune, but after the tune the TPS read a max of 94.3 for a few days and then dropped to a max of 86.1, where it has been for a couple months now. Is that just the norm for these, or should it read 100? Boost isn't weird, but I'm...

    Hello! So I purchased a used 2015 Kia Optima EX a few months ago with only 18k miles. Recently I have been hearing a "creeking" sound when I'm slowing down, or just slowly pulling off (letting off the break, but not yet pressing the gas). I took my car to my local KIA dealership where I bought...
  6. 3rd Generation Optima (2011 - 2015)
    My 2015 Optima EX only has 11k miles and I've noticed this issue for a long time now, maybe since new. I'll windex the inside of the windshield and within days or a week, it'll develop a thin film of something on the inside of the windshield again. Almost like what you see from heavy smokers who...

    For those that don't keep track of other people's cars... Mine is a 2012 Hybrid and almost 160Kmi. (Prob the highest mileage one on these forums.) Title says it all. HEV battery indicator had 2 pips on it and I tried going over 3000RPM. Optima said "Nope" and even downshifted to a higher gear...

    Hey all, I have a question and hoping someone can help. When I stop at a traffic light my RPM's will drop down to the .5 mark and the car will feel a bit shaky, almost like it wants to stall, but never actually does and the guage never drops lower. However, when i let go of the brake to start...
  10. 4th Generation Optima (2016 - 2020)
    Everytime I turn on XM/Sirius, there is a weird sound that happens after about 10 minutes or so. It's a loud electronic sound like bubbles gurgling underwater. It repeats 3 times and then the programming resumes. I've never heard this on XM before in other cars ... anyone else hear it, or am I...

    I will try to explain this as best as I can. This is happening on my 2014 SX Turbo The noise occurs in first gear when using manual shifting. When I accelerate and let off the gas pedal and press the pedal again, while still in first gear, I can hear a noise that sounds like a squeak of...

    I have started noticing a weird noise coming from dash or instrument cluster when AC is turned off. May be the noise is there when AC is running but I couldn't hear that much. Did anyone experience the same ? I am planning on taking my car to dealer tomorrow morning.

    2014 Optima EX w/Premium. 18,000 miles, bought new. Here in Arizona we don't see temperatures much below 40 degrees very often, so this problem may have existed for a while. In any case, when temperature drops in the 30s, and the car is been unused overnight, I run into this weird phenomenon...
