I have a 2022 SXP Awd. I notice sometimes when I park the car in my garage I hear what sounds like an actuator moving after I turn off the car. It seems like it happens after I drive down the long mountain road to my house. I guessing this might be the parking brake adjusting after the long drive using the brakes significantly. I did not set the parking brake. I do not have a towing package. Any ideas what this is? Thanks!

Hint: Use a descriptive title for your new message
If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "I need help with my SUV" could be about anything and can easily be overlooked by people who can help. However, "I need help with my transmission" will draw interest from people who can help with a transmission specific issue. Be as descriptive as you can. Please also post in the appropriate forum. The "Lounge" is for introducing yourself. If you need help with your leather interior, please post in the Interior section - and so on...

Noise after parking

I'm pretty sure this is common in many modern vehicles. I had it happen in my 2011 Toyota. I think it's the noise from the fuel evaporation leakage checking system as a diagnostic to make sure that vapor is escaping your fuel line. I've also found that if you get an error from this system test, the most common easy fix it to re-secure the gas cap. I haven't checked the Kia manual, but I would not be surprised if there is a mention of it somewhere. I think Kia calls this the On-board Refueling Vapor Recovery (ORVR). It just takes air out of your fuel line (aka fuel vapor) that builds up and gets introduced when filling up your tank at the gas station. It may also be the reason why measurement on your MPG computer might be off. You may be able to force a purge of the system by overfilling your take a few clicks at the pump then it will force the system to come on sooner and push the harmful vapors into the carbon canister.

Hmm, accurding to this tip from cars.com, overfilling may be harmful to both car and environment? https://www.cars.com/amp/articles/what-happens-when-you-fill-up-with-too-much-gas-442051/

I'm not suggesting anyone overfill all the time. I just saying that this is why your trip computer is off when compared to actually doing the math, it doesn't account for fuel vapor that might be present. If you scroll down this article and go to the Calibration section it will describe the process:
Why Your Trip Computer Isn’t Giving Accurate MPG Readings
And how to fix it. Cars' on-board fuel-economy meters can be inaccurate up to several percentage points.
