    2013 Kia Optima Ex Noticed I was low on oil and coolant yesterday, put some coolant in it, and it was due for a oil change so took it into Firestone today for a change. They didn’t try to upsell me anything and sent me on my way. I was in the process of installing a new fog light today and...
  2. 3rd Generation Optima (2011 - 2015)
    Water is leaking on the passenger side of my car and I’m positive it’s the AC drainage hose? (Not too sure exactly what it’s called but I’m hoping you know what I’m talking about) can anybody help me with where to access the hose so I can clear it out? Pretty sure it’s clogged and that’s causing...

    So I took my 2019 Optima in to a local dealership today due to a slight leak by the back of my interior roof lining, and the roof lining seems loose in the back as well it rattles when I go over bumps. So the dealership stated it is not covered by the warranty because they are blaming the...

    I'm not sure about this but from the way the fittings are installed, leads to believe this may cause boost leak. What do you guys think?

    I have '12 Optima and the AC system has leaked down. I have replaced system components before, used a vacuum pump, re-pressurized systems, etc. But only a shade tree mechanic. I bought a tool that lets you replace schrader valves in the AC pressure ports under pressure, and it works well...

    My wife took my 2011 Optima SX in for my oil change and they noticed I had a leak at my timing cover so they fixed it under warranty but when I drove the car for the first time since the repair I noticed I cant hear the turbo anymore and the car does not seem as responsive. I assume the battery...

    Had my CEL come on and had it read at an auto parts store thought it was the gas cap being that this cap is different than my other cars I have owned. (no not the first time that this has happened either LOL I own my stupidity but the auto parts store before turned off the cel) So off the...

    Hi everyone, my coolant suddenly started leaking yesterday at a very fast pace. It happened all the sudden when I noticed my car was overheating so I pulled over and found out I was out of coolant. I had some friends bring me some and filled it up and drove about 4 miles, stopping once to fill...

    Hey guys, so I bought used ark exhaust. Installed it yesterday, pretty straightforward. However, when I started it I had a small leak on the flange by the cat. I turned the flange upside-down and it fixed the main leak. However, there's a miniscule leak coming from the bolts. I'm talking about...

    Hello all, We bought the car new and have often smelled antifreeze when parking in the garage. I have been all over and under the car and have never found anything. Oil change before last, they came in and told us that our car was over a gallon low on AF so they added some. The last oil change...

    Alright guys need some help here. I started to notice about a basketball sized oil spot on the floor of the garage. Had my mechanic look at it and he determined it was coming from the backside of the engine possibly the turbo. So I make an appt at my local Kia dealership in hopes that it would...

    I was changing my oil today, and noticed some oil residue near the pan gasket. Does this look like a leak coming from somewhere? It seems too high up to be spillover from the drain plug or from the oil filter. Do you think this would be covered under factory warranty?

    So my windshield washer reservoir developed a significant leak yesterday... Great how it is not accessible except maybe through the passenger side wheel well. Oh well I guess I'd better figure this out to prevent a dealer trip... 6500 miles and first issue.

    So back in August I took in my LX because it appeared to be leaking a small amount of oil. I could tell by the amount of oil residue on the plastic panels just under the oil pan. I do all my own oil changes and I take the plastic panels off every time because I hate the mess the oil filter...
