NHTSA complaint #10985592, filed 2017-05, 95,718 miles“Engine locked up and needs to be replaced. I was told there was no oil in the engine at all, which seems to be due to a design defect causing no excessive engine oil consumption. I was driving on the interstate and barely made it the shoulder when the car seized up and died. No low oil light ever came on. If someone was driving in heavier traffic, the car could shut off in an active driving lane.”
