Hi all, Does anyone of you have any tips on how to avoid the petrol engine to start when driving in EV mode? I thought it had to do with the inside temperature of the car, i.e. it starts because the passenger compartment is too cold, but there seems to be a lot of other reasons as well. Today I...

Hi, I am new to these forums as me and my fiance recently purchased a 2015 Kia Optima SXL a little over 2 weeks ago. It had 120,000 miles, and we expected it to have some slight wear and tear, but we did get a good price for it in our opinion. But when we purchased it, we were told there were...

I am new to the KIA world and have had my Optima SX since November 2018. It has 127,000 Km's on it. The last 2 to 2 weeks in Calgary is has been -25C to -35C overnight and when I start the car the first time in the morning the exhaust is black and has a strong smell. It clears up and looks...

So this has happened twice now. Both times it was really cold (15 degrees today). It starts fine, but when I push on the gas, it goes but there is a severe loss of power... like I'm guessing it would take me a good 30 seconds or more to get up to 60 mph. On both occasions, a restart fixed it...

I'm mechanically inclined and have repaired various AC systems on cars, but I'm a little puzzled at the Optima. After buying new in 2012 the AC needed bit of a charge, so I used temp pressure chart and my gauges to add a can of 134a. This got it pretty much right on the money. The AC was blowing...

I have a 11 optima lx of course with the 2.4, ive gone through so far 2 intakes to test and see if the hesitation i was getting was because of the ebay branded intake or not. I first bought the cold air intake on ebay for 99 bucks shipped right? Okay, install went flawless car sounded great, but...

Have a 2015 KOH EX, living in SC, and it's been unusually cold this week. When we first start driving, after 30 secs to maybe 2 minutes, the radio flips back to the previous mode (Sirius to FM, or vice versa) and the maps starts initializing. Buttons are unresponsive for several seconds, then...

The last 2 days my car wouldn't start in the morning, been around 40 degrees or so,but probably about 30 this morning. After 10mins of pushing buttons it finally registered and got it going. Not sure if its the car, the fob, or just the battery. I had even tried my backup fob but it was even...

Does anyone know anything about this CAI from tuners depot? https://www.tunersdepot.com/2011-kia-optima-cold-air-intake-system/spyder-cold-air-intake-system-red-2.4l-4cyl-124411.html I'm wondering if it's any good

Ok all, to begin the car is an 04 kia optima in very good condition, my wife drives it as an everyday grocery getter, but recently there has been a weird creaking noise coming from somewhere in the engine bay or in the front of the car. It occurs when it's cold outside and when coming to a stop...

I spent over $800 on the CAI setup in my RAM, with little benefit. I swore when I did this next I would put a good quality filter element in the stock housing and add a DIY "ram air" for fresh, cold air into the filter housing. Looking at something like this...

hey optima owners, just having an issue with my optima, which i can only describe as what would be an stuck open thermostat, but my optima with 25k thousand kilomters on it, takes forever to warm up to normal operating temperature, like 20 min of active driving, and wont stay at normal...

Hi! The locks have started acting up now when winter has started. When I turn the key to unlock I feel resistance and the key kind of springs back, but the locks are unlocked. If I open the backdoor it's open and all fine, but if I pull the front door handle the central lock kicks in and all...

Does anyone have, or know where I can find a cold air intake for 2016 Optima 2.4L? Thanks.

Hi everyone, I've been searching everywhere for a cold air intake for my 2.4L 2016 Optima but no company has made one yet. I contacted K&N about making one and I'm hoping if enough people request it they will do it. Here is a link to request a new part:Request a K&N Product for Your Vehicle...

SO many of us have experienced some pop's/intake back fires on cold starts with aftermarket intakes installed...well I have been doing something the last 4 days that has STOPPED THIS COMPLETLEY... I have a boost gauge installed and noticed the engine gets pretty close to no vacuum/boost under...

Hi everyone, I have a 2014 Optima EX 2.4L and had a question about it. Almost every morning on a the first cold start of the day, there is a pretty loud knocking sound on start up which is there for a few seconds and eventually goes away. I don't remember hearing this noise until recently so I...
