    Right after I bought the car the check engine light came on so I am not sure when it actually started. I bought it second hand. i have not fixed it.

    Just out of the 6 year / 100K certified warranty. It cost me over $1000.00 to repair. I was told this is because engine oil consumptiom burns them out.
