Stop replacing parts, do a smoke test next.

FYI R134a is refrigerant, not freon.

The engine looks very clean under the valve cover, I bet someone used full synthetic oil in that engine!!

What's the aluminum foil over the brake fluid reservoir for I wonder??

Hi, it’s a resonator used to make the air intake quieter. It’s more technically called a Helmholtz resonator I believe. See https://duckduckgo.com/?q=air+intake+re ... ltz&ia=web

Did you use a known good scan tool that has read the codes on your car before? It's possible the code is not in history.

Given the multitude of trans problems with these vehicles it's not reassuring that you may have a transmission problem...

Whoa, you are an old-timer here. OK then. I know Hyundai has really ramped up their game in the last 10 years, I think Kia too since it's the same company. I don't have any Kia forums so good luck

$235... a little steep. Considering there is no recalibration, all they have to do is repair some solder points and test it. If you have a real electronics wizard where you live such as a guy that installs remote start systems etc. he may be able to fix it for less. I know a guy who is a total wizar...

If you're using a Motorcraft oil filter you shouldn't need to mess around with changing the filter at the halfway mark. You could potentially go way past 7,000 miles but you would want to do an oil analysis such as https://www.blackstone-labs.com/tests/standard-analysis/ to tell you how much life is...

Have you scanned for diagnostic codes? I would check fuel pressure next.

Yes, reset it at the next oil change.

You should focus on the actual miles driven since the last change. Do not rely on the electronic readout at this point.

How many miles have you put on since the last oil change? The owners guide calls for 5,000 mile intervals. Was the oil life monitor reset at the last oil change? See https://www.myfordfreestyle.com/forums/viewtopic.php?t=3356 - if it was not reset when the oil was changed the message you see now may...
