Driving at 60 mph on the highway engine seized up with no warning what so ever no engine light or oil light. Once vehicle stopped checked oil and it was almost empty. No warning of oil pressure or oil low. Vehicle always inspected an oil change done on time. Can't find recall on my vin but other 2012 models had a recall for this exact reason. I was almost hit by a semi when the vehicle just died with no warning at all and everything locked up. Never had 1 issue with this vehicle until now. And I am worried kia will not fix it when clearly other optimas of the same year had the same issue. I can't understand why when vin search it doesn't show this recall. It's all over the internet.

Oil changed every 3000 miles. Driving to work the other day check engine light came on. Car went into limp mode. Pulled code and it was for rod bearings. Supposedly rod bearings had been repaired by recall before. Car only has 91,000 miles on it. So shouldn't need another set of rod bearings if previously replaced.

When getting on oil change at myCarDoc they wrote the wrong mileage on my car so the CARFAX is off. My engine broke down randomly the other day on the highway and now I need a whole new engine..and to find out the mileage was off when getting maintenance done.
