Hi all, I have a 2019 Kia Stinger GT RWD that has been in the shop 3 times all with rear differential failure. The original diff failed in June 2023. It has currently been in the shop since December. Kia did a thorough inspection of my car to make sure I was not abusing it. Now they have a technical specialist trying to figure out what is causing it. They think it is the oil and they use Valvoline with the limited slip additive. Another stinger came in in December with the same issue, they replaced her differential and in one month it was toast.
Is this an oil issue? Does anyone else use Valvoline in a different vehicle as their gear oil? Did they change the fluid after all of the issues with Covid and getting supplies? Just trying to figure out what’s happening here.
