Recently there was a Technical Service Bulletin (TSB: 23-016-21 REV. A ) that appears to address concerns similar to the symptoms that you are having with your vehicle. To ensure this TSB applies, we would like to get you back into the dealer to have a qualified technician review the details of the TSB and specifics of your vehicle.
