Hello -- on our 2016 Sorrento SX, I recently had the CEL (check engine light) come on, so I got out my ODB2 reader and scanned the codes.

I replaced the O2 sensor which was indicated as bad, cleared the codes, but it threw the same code immediately.

About the same time, the hatch actuator failed, so I took it to my local KIA dealer service department.

They, too replaced the sensor with the same results. Upon further inspection, they discovered rodent damage to the wiring harness, and they sent me a photo of literally 2 damaged and one interrupted wire.

Of course, it's damage, not a MFG defect, so not covered under warranty, which I understand. I haven't gotten the quote for repair yet, but expect it to be $$$$$ as he suggested we try to get our auto insurance to pay for it.

I mentioned that I could easily repair that damage, and the service tech claimed that a DIY repair on the wiring harness would void the vehicle warranty as being "modified."

Is this true?

I understand EFI and wiring -- I've built and programmed an EFI system for a motorcycle from the ground up using a stand-alone system, so I trust my ability to both grasp the importance of correct resistance and correctly install and weatherproof the repairs to the wiring. But that's not really the issue, and I doubt that KIA will make exceptions to policy based on my experience.

I just want to know what the actual policy is. Does KIA prohibit wire-level repairs, or is my dealership trying to increase their bottom line during these lean times?

Another good question is if California has an automotive right-to-repair law that applies to DIY. The ones I've found reference making schematics and factory tools available.

Outstanding responses, thanks to all who participated.

I wrote my original question over a holiday weekend, and on Monday, I called KIA customer support. They verified that a DIY repair would not void the vehicle warranty, as had been implied by the service writer at the dealership. It would however, void the warranty for that particular part, and any damage caused as a result of the repair.

Also, the quote for the repair -- hold on to your hats... was $1065 for labor, and $2722 for parts... plus tax... for a total of $4087!
