REPLACEMENT OF LOWER LEFT CHARGE AIR HOSE
It has been determined that due to a change in the shape of the bottom left molded charge air hose, the MAF (mass airflow sensor) may measure the airflow incorrectly. Therefore, the charge air hose must be replaced. Please perform this Service Campaign during the vehicle's next scheduled service visit.
Prior to performing this Service Campaign, please check VMI to insure the vehicle is involved and to determine if the vehicle has been previously repaired.
