KRW,
I would like to apologize for the issues that you are experiencing with your vehicle. I would recommend that you have your dealer look into this for you. They may be in the best position to assist you in getting this diagnosed for you. Please keep me posted and if you have any other questions please feel free to contact me anytime.
Thank you,
