Replacing engine and got questions about it


@Sung
I had a licensed mechanic friend double-check and he agreed with the issue. Would that count?

It might, but you’d probably need an actual invoice to make it official. Could your friend print it on company letterhead?

Something informal won’t work. Treat it like preparing for court—get everything documented properly. You’ll also need the Sedona letter to back up your case.

I can get a printed invoice without any problem.

Alright, then take that paid invoice, showing the head bolt issue, and mention the mechanic told you about an extended warranty. Stop working on it, contact Kia corporate, submit your invoice, and request an official dealer review. You might need to tow it there.

If you’ve already replaced the engine at your expense, Kia might have to reimburse you if the warranty applies (with proper documentation). That’s how it works for the Sorento at least.

Don’t get your hopes too high though—I haven’t seen the Sedona letter, so it might not apply. Try to get a copy if you can.

This is just my advice from someone on the internet. Best of luck and happy holidays.

Thanks so much for the advice! Really appreciate it. Happy holidays to you too.

Let me know how it turns out if you remember. It might help the next person.

Adding to the original post—I came to ask about replacing an engine in the same van for similar reasons (head bolts are stripped, and the block is done for).

My van (technically my wife’s, it came with her) is out of the extended warranty, so we’re deciding between swapping the engine ourselves or just getting a different car.

I’ll say this upfront—don’t ever buy Kia or Hyundai. But if you’re thinking of getting a used engine, try matching both VINs to ensure it’s compatible on Kia parts websites.

That said, I’d seriously consider a remanufactured short block instead, especially if the head is ready for installation. A remanufactured block can cost less or about the same as a used engine. Compare prices from different places and look for options nearby to avoid shipping fees. If you go this route, make sure you return the core in its original packaging to avoid losing the core deposit, which can be over $1,000.

The warranties and letters differ between the Sorento and Sedona models.

Avoid Kia or Hyundai altogether.

Wow, what a helpful comment.

My Hyundai Sonata lasted 190,000 miles, and the only major work it needed was a timing belt and two gas tanks. I really loved that car.

I just got rid of my Kia a few days ago. Never buying one again—they’re so poorly made.

Funny enough, I feel like I’m the only one who loves my Kia. It’s been through a lot of rough drives and still holds up.

You’re not alone. Our 2018 Optima had 30,000 miles when we got it, and it was serviced regularly at the dealer. I handle maintenance myself now, and my wife loves it. It’s been great so far.
