Missing coolant and refill alert unfixable

Yes I think so. They're the same basic drivetrain I believe.

Look at this... https://static.nhtsa.gov/odi/tsbs/2021/MC-10191531-0001.pdf it's a TSB for it. If you listen to the "Normal" vs "Abnormal" mine is probably closer to "normal" which is why they won't do anything...but I've been paying attention and it's definitely getting worse/louder over time. Meanwhile my Bolt with more mileage sounds smooth as butter. Apparently Kia just makes s&*t motors.

 

Out of curiosity, how did you sell it? I could easily sell the car for a reasonable price but haven't because I'm hopeful Kia can just fix the thing (we liked the car), I'd take a huge hit selling a car with a warning on the dash that won't go away (trying to sell a car with such an obvious unrepairable defect), and repurchasing a new car at today's inflation + interest rates would be another bath. We're kind of dragging our feet since it would cost so much money to replace.
