Anyone else: Coolant is old by time but low mileage

CanyonMom18Community StarterJan 13, 20262023 Hyundai Ioniq 5 LimitedChicago
Car only has 32k miles but the coolant is several years old. Would you change it based on age alone? I'm trying to prioritize maintenance that matters rather than replacing everything early. I'd rather test this logically than start replacing parts.

The trap is a pretty payment hiding a worse car price. In Chicago, insurance quotes flipped a 2023 Hyundai Ioniq 5 comparison for me more than the sale price did. Then the comparison gets honest. Learned this the expensive way on a previous car. Doing the boring step first on purpose.

Compare apples to apples or you'll get spun. A written buyer’s order on the 2023 Hyundai Ioniq 5 is worth more than any verbal “we’ll make it work.” If they balk, that's your answer. If it doesn't change the out-the-door or the repair estimate, it's noise. Sleeping on the number either way.

Get the messy numbers in writing first. GAP, paint, and nitrogen are optional until you run the 2023 Hyundai Ioniq 5 numbers without them. If they balk, that's your answer. On “coolant is old by time but low,” that was the fork that mattered for me. This is from a 2023 Hyundai Ioniq 5 in Chicago. Stop there until you know. I asked for the buyer’s order in email, not a text.

Quick update: a second 2023 Hyundai Ioniq 5 quote made the first offer look ordinary. That's my plan before I call anyone.

I'd want competing paper, not competing stories. A written buyer’s order on the 2023 Hyundai Ioniq 5 is worth more than any verbal “we’ll make it work.” Do that before you talk monthly again. That's the whole play. This is the version I'd tell a friend.

I'd want competing paper, not competing stories. Call your insurer in Chicago before you fall in love with the 2023 Hyundai Ioniq 5. I'd rather lose the car than buy a foggy deal. Had a similar mess a couple years ago and that's what finally sorted it. I'd sleep better after that step, even if it finds nothing. Going to re-read the worksheet tonight.

I'd slow the salesperson down here. If they're pushing term length to shrink the payment, the 2023 Hyundai Ioniq 5 price probably got worse. That's the part that actually changes the decision. Learned this the expensive way on a previous car. That's coming from doing this as an owner, not a shop. If the VIN lookup is clean I'm still doing PPI.

I'd slow the salesperson down here. Two 2023 Hyundai Ioniq 5 quotes only help if both include tax, title, and the same options. That's the part that actually changes the decision. A shop burned me once by skipping that step. A day of patience here is cheaper than a wrong part. I'm in no rush to be a hero on it.

Hard-won lesson from my last deal: GAP, paint, and nitrogen are optional until you run the 2023 Hyundai Ioniq 5 numbers without them. Do that before you talk monthly again. On “coolant is old by time but low,” that was the fork that mattered for me. I'd want a dollar figure or a measured spec, not 'should be fine.' Wrote this up on my lunch break.

OP update: I got two written quotes on the 2023 Hyundai Ioniq 5 and the out-the-door gap is bigger than the ads made it look. I screenshotted the quote for later.

The trap is a pretty payment hiding a worse car price. I would not wire money until I've seen the 2023 Hyundai Ioniq 5 and the title situation in person or via a trusted PPI. That's the part that actually changes the decision. If they can't show the line item, I assume it's hiding. Worth doing even if the car feels fine right now. I'll update if anything new shows up.
