Models:
2013 Cadillac XTS
Supercede:
This bulletin has been revised to extend the expiration date to November 30, 2013. Please note that the service procedure contained in this bulletin must be performed only on sunny days with an ambient temperature over 24 degrees Celsius (75 degrees Fahrenheit). If these conditions do not exist, do not perform this update at this time. The inspection will not be accurate if performed during cool/cold weather. Please discard all copies of bulletin 12153A.
This service update includes vehicles in dealer inventory and customer vehicles that return to the dealership for any reason.
It is imperative that technicians perform this inspection on vehicles while the weather is still warm.
Purpose
This bulletin provides a service procedure to inspect and, if necessary, replace the instrument cluster on certain 2013 model year Cadillac XTS vehicles. When the interior of these vehicles becomes hot, communication to the infotainment system may be lost. This can cause loss of the infotainment audio, steering wheel switch controls, display of radio information such as song and artist information, and steering wheel switch backlighting. This condition may correct itself when the vehicle is turned off and if the interior of vehicle cools. However, the condition may continue to occur in the future.
This service procedure should be completed on involved vehicles currently in dealer inventory and customer vehicles that return to the dealer for any type of service as soon as possible, but no later than November 30, 2013, at which time this bulletin will expire.
Vehicles Involved
All involved vehicles are identified by VIN in the Global Warranty Management System - Investigate Vehicle History Application. Dealership technicians 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.
Additionally, a list of involved vehicles currently in dealer inventory is available on the "Service Update Bulletin Information" link under the "Service" tab in GM GlobalConnect (US) or attached to the GlobalConnect message (Canada) used to release this bulletin. Customer vehicles that return for service, for any reason, through November 30, 2013, should also be checked for vehicle eligibility.
Parts Information
25% of involved vehicles are expected to require replacement of the IPC. If the inspection determines that replacement is required, contact a GM Authorized Electronic Service Center (ESC) to order an instrument panel cluster.
Return the removed IPC using the pre-paid Automatic Return Shipping (ARS) label included with the exchanged IPC. Package the removed IPC in the original packaging and package inserts provided by the ESC. It is important that the returned IPC unit be packaged identically to the exchange IPC to prevent damage in shipping. To avoid charges to your Open Parts Account, return the core within 30 days.
