SERVICE CAMPAIGN BULLETIN

SERVICE INFORMATION

All involved vehicles that are in dealer inventory must be held and not delivered to customers, dealer traded, or used for demonstration purposes until the repair contained in this bulletin has been performed on the vehicle.

THIS PROGRAM IS IN EFFECT UNTIL AUGUST 15, 2016.

CONDITION

Certain 2014 model year Cadillac CTS (VIN A) model vehicles equipped with the 2.0L turbo engine (RPO LTG) may experience engine damage if the vehicle is idled for long periods of time - usually at ambient temperatures greater than 32° C (90° F) with air conditioning on resulting in intake air temperature rising to greater than 80° C (176° F) sustained - followed by aggressive driving at Wide Open Throttle.

CORRECTION

Dealers are to reprogram the ECM (Engine Control Module) with updated software.

VEHICLES INVOLVED

All involved vehicles are identified by Vehicle Identification Number on the Investigate Vehicle History screen in GM Global Warranty Management system. Dealership service personnel should always check this site to confirm vehicle involvement prior to beginning any required inspections and/or repairs. It is important to routinely use this tool to verify eligibility because not all similar vehicles may be involved regardless of description or option content.

For dealers with involved vehicles, a listing with involved vehicles containing the complete vehicle identification number, customer name, and address information has been prepared and will be provided to US and Canadian dealers through the GM GlobalConnect Recall Reports, or sent directly to export dealers. Dealers will not have a report available if they have no involved vehicles currently assigned.

The listing may contain customer names and addresses obtained from Motor Vehicle Registration Records. The use of such motor vehicle registration data for any purpose other than follow-up necessary to complete this program is a violation of law in several states/provinces/countries. Accordingly, you are urged to limit the use of this report to the follow-up necessary to complete this program.

PARTS INFORMATION
