14515 – Chassis Electronic Control Module Internal Contamination – 2007-2014 Buick Cadillac Chevrolet GMC Hummer Saturn

Bulletin No.: 14515B
Date: January 2015

PRODUCT SAFETY RECALL

This bulletin is being revised to identify modules for use with RPO JL1 in the parts information chart, and to add the 3500 series pickups to the labor time chart. Please discard all copies of bulletin 14515A.

It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.

Vehicles involved in this recall were placed on stop delivery October 1, 2014. Once the service procedure contained in this bulletin has been performed on the vehicle, the vehicle is released from stop delivery and the vehicle can be delivered to the customer.

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.

Condition

General Motors has decided that a defect which relates to motor vehicle safety exists in certain 2013 – 2014 model year Cadillac CTS, Escalade, and Escalade ESV vehicles; Chevrolet Suburban and Tahoe vehicles; and GMC Yukon and Yukon XL vehicles and certain 2014 model year Buick Enclave vehicles; Chevrolet Express and Captiva, Impala Limited, Silverado HD and Traverse vehicles; and GMC Acadia, Savana and Sierra HD vehicles.

Some of these vehicles were built or serviced with contamination within the chassis electronic module.

This contamination can cause an electrical short in the module. If the module experiences an electrical short, the vehicle could display a check engine light, stall, or fail to start.

If the vehicle is equipped with a trailer brake, the vehicle could lose trailer brake function and display a “Service Trailer Brake System” indicator.

If the vehicle experiences this condition and stalls while in motion, there could be an increased risk of a vehicle crash.

Additionally, a small number of 2007-2012 model year vehicles that include; 2008-2013 Chevrolet Avalanche, 2008-2009 Chevrolet Colorado vehicles; 2007-2013 Chevrolet Silverado, 2008-2014 Suburban, and Tahoe vehicles; 2008-2013 GMC Sierra and 2009-2012 Yukon vehicles; 2008-2009 GMC Canyon vehicles; 2009-2010 HUMMER H2, H3 and H3T vehicles; and 2008-2009 Saturn VUE and 2009 Outlook vehicles may have been serviced with a chassis electronic module that could have internal contamination, causing an electrical short in the module.

If the module experiences an electrical short, the vehicle could display a check engine light, stall, or fail to start.

If the vehicle experiences this condition and stalls while in motion, there could be an increased risk of a vehicle crash.

Correction

Replace the chassis electronic module on all affected vehicles.

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 recall 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 recall.

Courtesy Transportation – For US and Canada

The General Motors Courtesy Transportation program is intended to minimize customer inconvenience when a vehicle requires a repair that is covered by the New Vehicle Limited Warranties.

The availability of courtesy transportation to customers whose vehicles are within the warranty coverage period and involved in a product program is very important in maintaining customer satisfaction.

Dealers are to ensure that these customers understand that shuttle service or some other form of courtesy transportation is available and will be provided at no charge.

Dealers should refer to the General Motors Service Policies and Procedures Manual for Courtesy Transportation guidelines.

Warranty Transaction Information

Submit a transaction using the table below. All transactions should be submitted as a ZFAT transaction type, unless noted otherwise.

Note: To avoid having to “H” route the courtesy transportation, floor plan transaction for approval, it must be submitted prior to the repair transaction.

* The amount identified in “Net Item” should represent the product of the vehicle’s average daily interest rate (see table below) multiplied by the actual number of days the vehicle was in dealer inventory and not available for sale. This reimbursement is limited to the number of days from the date of the stop delivery message (October 1, 2014) to the date the repair is completed and the vehicle is ready for sale (not to exceed 87 days):

Customer Notification – For US and Canada

General Motors will notify customers of this recall on their vehicle (see copy of customer letter included with this bulletin).

Customer Notification – For Export

Letters will be sent to known owners of record located within areas covered by the US National Traffic and Motor Vehicle Safety Act.

For owners outside these areas, dealers should notify customers using the attached sample letter.

Dealer Recall Responsibility – For US and Export (US States, Territories, and Possessions)

It is a violation of Federal law for a dealer to deliver a new motor vehicle or any new or used item of motor vehicle equipment (including a tire) covered by this notification under a sale or lease until the defect or noncompliance is remedied.

The US National Traffic and Motor Vehicle Safety Act provides that each vehicle that is subject to a recall of this type must be adequately repaired within a reasonable time after the customer has tendered it for repair.

A failure to repair within sixty days after tender of a vehicle is prima facie evidence of failure to repair within a reasonable time.

If the condition is not adequately repaired within a reasonable time, the customer may be entitled to an identical or reasonably equivalent vehicle at no charge or to a refund of the purchase price less a reasonable allowance for depreciation.

To avoid having to provide these burdensome remedies, every effort must be made to promptly schedule an appointment with each customer and to repair their vehicle as soon as possible.

In the recall notification letters, customers are told how to contact the US National Highway Traffic Safety Administration if the recall is not completed within a reasonable time.

Dealer Recall Responsibility – All

All unsold new vehicles in dealers’ possession and subject to this recall must be held and inspected/repaired per the service procedure of this recall bulletin before customers take possession of these vehicles.

Dealers are to service all vehicles subject to this recall at no charge to customers, regardless of mileage, age of vehicle, or ownership, from this time forward.

Customers who have recently purchased vehicles sold from your vehicle inventory, and for which there is no customer information indicated on the dealer listing, are to be contacted by the dealer.

Arrangements are to be made to make the required correction according to the instructions contained in this bulletin.

A copy of the customer letter is provided in this bulletin for your use in contacting customers.

Recall follow-up cards should not be used for this purpose, since the customer may not as yet have received the notification letter.

In summary, whenever a vehicle subject to this recall enters your vehicle inventory, or is in your dealership for service in the future, you must take the steps necessary to be sure the recall correction has been made before selling or releasing the vehicle.
