actual written confirmed source
I thank you sir. I appreciate your input. Where in writing is this stated??? Or is this just your opinion?I dont think you understand how this works. No mods will void your warranty. If an Aftermarket part or modification to an OEM part is a source of a warranty claim that claim may and can be denied.
This is the response I was looking for. Thanks much.US Federal Trade Commission:

Will using 'aftermarket' or recycled parts void my warranty?
No. An 'aftermarket' part is a part made by a company other than the vehicle manufacturer or the original equipment manufacturer. A 'recycled' part is a part that was made for and installed in a new vehicle by the manufacturer or the original equipment manufacturer, and later removed from the vehicle and made available for resale or reuse. Simply using an aftermarket or recycled part does not void your warranty. The Magnuson-Moss Warranty Act makes it illegal for companies to void your warranty or deny coverage under the warranty simply because you used an aftermarket or recycled part. The manufacturer or dealer can, however, require consumers to use select parts if those parts are provided to consumers free of charge under the warranty.
Still, if it turns out that the aftermarket or recycled part was itself defective or wasn't installed correctly, and it causes damage to another part that is covered under the warranty, the manufacturer or dealer has the right to deny coverage for that part and charge you for any repairs. The FTC says the manufacturer or dealer must show that the aftermarket or recycled part caused the need for repairs before denying warranty coverage.

So basically.....Go for it but, you may possibly open yourself up to a repair being denied under warranty or even having your warranty denied in total and have to litigate with KIA. Does that sound accurate? Thank you.

Okay. I understand now. I think I'll pursue only aesthetic mods and pass on anything that changes or updates the OEM mechanical or electrical. I'm not up to adding another conflict in life.Entire warranty can not be "voided". A Claim can be denied for aftermarket parts or modifications.
Its not an opinion just google Magnuson-Moss Warranty Act. Simple research should be more helpful to understand things.
Last summer I had an engine light come on and the car went into limp mode on the highway while using (Eco mode lol), pulled over and restarted the car. It drove fine but still had a check light on.
At the time my only mod was an aftermarket intake and when I took it in to the dealer, they checked it out the next morning and the light was gone but they were able to pull the code. It was a torque control module code and they were pointing finger at my intakes and saying things like “modifications will void your entire warranty” which I promptly corrected them, asked them to clear the code and took the stinger home, haven’t had an issue since.
Lessons from my experience are that they will use any related mods to the issue/problem to void warranty work and avoid using eco mode.
This is true and false at the same time. The flat rate for warranty work is true. The part about them being able to charge whatever they want is false. Almost every job has a flat rate. Customer pay flat rate tends to be higher than warranty work. Most shops use alldata labor times or something similar to determine the flat rate charged for a job.Dealer service shops get paid a KIA-determined flat-rate for warranty work. They can charge whatever they want for customer-paid repairs.
I wasn't outright denied warrantied service, but when I took my car in thinking I might have a blown shock...I was informed that it might not be covered because of my sway bar. Though, they said shocks probably wouldn't be covered anyway. In any event, turns out they seemed to find nothing wrong. I think there is something wrong as I have this weird "thud" type sound when I go into dips. Probably just me, as I'm still not use to the rubber band tires.![]()
That “thud” is likely your hatch clunking. Do some searching here for the DIY repair for this.
Why avoid using eco made?Last summer I had an engine light come on and the car went into limp mode on the highway while using (Eco mode lol), pulled over and restarted the car. It drove fine but still had a check light on.

I wouldn’t say avoid it now but I just don’t use it.Why
