My son just bought a 2022 Kia Sorrento plug in hybrid with 23000 miles on the odo.
He noticed very hard shifting and took it in for service. the dealer re-flashed the transmission computer but the hard shifting continued.
Long story short it’s at the Kia dealer who is replacing the current transmission with a new unit.
He was told that they had done three others with the same problem. Thankfully it’s covered under warrantee because the cost to replace by a Kia dealer is around $14,000.
I would really think hard before I bought one.
