Low Conductivity Coolant Flush

Hey Everyone

I have an 2023 Ioniq 5 with about 36,000 miles. I knew about the LCC replacement at every 35k miles and called around 5 dealerships about it. Some dealer said it was at 35k since it is mostly driven in Texas and some dealers are saying at 70k. My questions is, has anyone had anyone problems to their cars due to not changing the LCC at 35k miles? I'm debating if I bite the bullet and pay $650 (cheapest around me) to get it replace or is it something that isn't necessary. I know the it is something that can come back to me if the battery fails due to not replacing the LCC.
