I had the same problem, turned out the dealer put 2012 mirrors on my car when I bought it which caused the check engine light. They took the '12 mirrors off and gave me new power heated tow mirrors and I'm not sure I'm a 100% fan of the look of them.
any way you would be interested in selling the stock mirrors if you still have em?
