2022 GT Elite maintenance

[Rahooligan]

Hi I have a 2022 gt elite AWD 3.3 in canada
Currently at 67,000km got at 25,000km

So far I’ve done oil changes every 6-7k km

Brake fluid replaced once

Was told to wait for rear diff fluid/ transmission fluid. Whenever I ask dealer for a quote or what the process is they can never give me a clear answer. Does anyone know when to replace tran fluid (does it need to be just a simple drain and fill/any other part/fluid needed) for diff fluid same thing?

Was also told I am overdue for my carbon induction service and need to replace my spark plugs. Any advice on these?

Thanks!!!!!!!

Don't do plugs until you have an issue with misfiring or loss of power/acceleration. The dealer will of course disagree. It isn't a warranty issue because bad plugs won't hurt an engine, just make it run like crap, and you'll get new plugs then and there, problem solved. The dealer/KIA says change them every 42K miles. That is overkill. A guy on here was bragging his original plugs had taken him over 200K miles. But possibly that is overkill the other way. Ha hah.
