“After inspection, the service agent, Jeff, came and informed me there was “good news and not so good news”. Good news - He said there was a 999,999-mile warranty on the engine for the oil pressure stick problem. The not so good news is that Kia will not replace the engine until it locks. I was shocked to say the least. I asked him, how in the hell is that safe? Why isn’t the fact that the car started shutting down on me (power steering) enough of an indication that it needs to be replaced? That along with the amounts of oil I’ve had to replace. …”
