  1. 3rd Generation Optima (2011 - 2015)
    The 'set' switch on our 2014 EX Optima has failed. It seems the spring mechanism that keeps the switch centered is broken. Unable to set cruise due to the thumb switch being dysfunctional. I have found the switch on ebay but want to make sure this is a DIY type replacement. Anyone know of a...

    What is the proper battery replacement for a 2019 Kia Optima FE ? My car stopped working the other day and had AAA come out to help diagnose this issue and they said i have a bad battery. Bought this car less than 6 months ago and have always brought it in for maintenance when it is due. Also...
  3. 3rd Generation Optima (2011 - 2015)
    2012 SX ... I've had the car for 45 days and noticed I have a headlight out. Still fairly unfamiliar with the car. Purchased replacement HID's from K5Optima. Took me a minute to even find the screw to get the weather seal cap off, ha. Do I have to take the **** bumper off? Once I do, how do I...

    KIA TRS/Inhibitor Switch Replacement (Fix for OBD Code P0705 or missing gear display) I recently had a CEL on my 2011 Kia Optima and also weird behavior with the A/T (gear indicator on dash was blank and sometimes the A/T wouldn’t automatically shift all the way down to 1 at stops sometimes). I...
  6. 3rd Generation Optima (2011 - 2015)
    So I have a 2011 Kia Optima SX that had ECU update done a few months ago. 5 weeks ago the engine light started flashing and went into limp home mode with a max 2,000 rpm. I took it to my local dealer (Napleton Kia of Carmel). They checked the engine and said it need to replaced. They got it...
  7. Wheels, Tires and Suspension
    Took me about 45 minutes to change both out but its amazing the difference even thou I still feel a little road vibes. All Ive done is put on new tires and end links, was thinking struts and maybe ball joint? Any info would be great
  8. 3rd Generation Optima (2011 - 2015)
    Sadly my 2015 SX (77,000 mostly miles) got nailed by a hit & run Cadillac Escalade driver. It will no doubt be a total loss. I am trying to determine roughly how much I can expect to be offered. I had about $3,500 in modifications (USAA insurance) and still owed about $9,000 on it. I've never...

    I'm wanting a different exhaust system with a little more sound than the stock, but without it sounding like an angry bee. I have looked at borla, but not a huge fan. Can't seem to find many videos regarding upgrades on the exhaust or horsepower for that matter regarding the turbo. Anyone have...

    Hi all, Haven't posted in a long time but was looking for advice on an issue I am having. I have a 12' LX with the steering coupler issue. I brought the car into dealership where they told me yes, the coupling does need replacing. However, they are unable to do the job because of wiring...

    Is it difficult to replace the standard driver's side seat with a power seat? I found one at one of my local used parts providers, but didn't know if it required more than just unbolting the standard seat and hooking the new seat cable to the existing coupler.

I bought them and went to have them installed and they said they didnt fit. They came from china. I just want to know if anyone has purchased some of these in america or a...

    My driver-side seat bottom warmer stopped working, thankfully it's still under warranty, I was just curious if this is a fast fix (2-3hours) or should I expect to leave my Optima all day at the dealer. I called them and posed the same question, they were very non-committal, wouldn't even give me...
  14. Engine and Technical Discussion
    Kia recently replaced the complete long Block in my car (2014 sxl) and it almost seems as though they are maybe detuning them so they don't have future issues like maybe they lowered the compression ratio or change the valve timing a bit? I'm not saying it's now a dog just seems little less...
  15. Engine and Technical Discussion
    My belt has tiny cracks in it and the mechanic told me it's due. I said to leave it for now but after smelling burnt rubber a couple of times,I figured it's from that belt. So I'm having it changed at the dealer while it's going in for a gasket replacement. Car only has 56k km. Anyone else...
  16. 4th Generation Optima (2016 - 2020)
    Has anyone had the pleasure of having to replace their battery yet? Well mine died this morning. Went to start it and it did some really strange things; dash lit up like a Christmas tree, headlights started flashing, and there was a crazy loud clicking noise coming from under the hood. Jumped...

    Hello all! Long time lurker here. Bought my Optima a year old and any time I had an issue or question this is where I came. Well I have an issue. Walked out to my Optima, which was sitting in my driveway, and found the drivers mirror hanging by the wires. Who knew mirrors just fell off. :$...

    Correct me if I am wrong but the Infinity dash drivers come with 4 wires. 2 to the mids and 2 to the tweeters. There are no crossovers on the drivers because i would assume the amp does that for you. So the signal coming to the driver is already at over 800hz. So there is no need to add bass...
