I purchased the car last weekend as a CPO with 5995 miles.How many miles, and did you buy the car new? sound silly to ask that?
If you bought the car new it has a warranty till 5 years or I think it is 60,000 miles.
Used it depends on dealer warranty given to you.
certified preowned 1 year or 12,000 miles, unless you took out the extended warranty
Others have had the same issue so try for KIA to fix it even if your out of warranty
