Recall Bulletin

F/CMVSS NONCOMPLIANCE RECALL
SUBJECT:

Driver Shift Control Feature May Disengage

MODELS:

2013 Buick LaCrosse
2013 Cadillac SRX

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 certain 2013 model year Buick LaCrosse and Cadillac SRX
vehicles fail to conform to Federal/Canada Motor Vehicle Safety Standard 102, for engine
braking. The transmission software in these vehicles may cause the transmission to shift from
Driver Shift Control (DSC) mode to Sport mode unexpectedly.
These vehicles are equipped with the DSC feature that allows the driver to shift the automatic
transmission similar to a manual transmission. If the DSC mode disengages, the transmission
will return to automatic mode, and if engine braking was being provided, it will be cancelled
and the vehicle will be in Sport mode.
If this condition occurs, DSC mode can be re-engaged by moving the shift lever to Drive and
then back to the DSC mode.
CORRECTION
Dealers are to reprogram the transmission control module.
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.
PART INFORMATION
No parts required
SERVICE PROCEDURE
Transmission Control Module (TCM) Programming Instructions
Do not attempt to order the calibration number from GM Customer Care and Aftersales. The
calibration numbers required for this service procedure are programmed into control modules
via a Multiple Diagnostic Interface (MDI) with the calibration update. When using a MDI for
reprogramming, ensure that it is updated with the latest software version. Use TIS2WEB on or
after 3/07/13 to obtain the calibration. If you cannot access the calibration, call the Techline
Customer Support Center and it will be provided.
For step-by-step programming instructions, please refer to SI and the Techline Information
System (TIS) terminal.
1.

Verify that there is a battery charge of 12 to 15 volts. The battery must be able to
maintain a charge during programming. Only use an approved Midtronics® PSC 550
Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain
proper battery voltage during programming.

2.

Reprogram the transmission control module (TCM). Refer to SI and Service Programming
System (SPS) documentation for programming instructions, if required.
2.1 Connect the MDI to the vehicle.
2.2 Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and
Programming Process screen.
2.3 Select TCM Transmission Control Module -- Programming from the Supported
Controllers screen.
2.4 Follow the on-screen instructions.

3.

Clear all diagnostic trouble codes (DTCs).

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.
This bulletin is notice to you that the new motor vehicles included in this recall may not
comply with the standard identified above. Under Title 49, Section 30112 of the United
States Code, it is illegal for a dealer to sell a new motor vehicle which the dealer knows
does not comply with an applicable Federal Motor Vehicle Safety Standard. As a
consequence, if you sell any of these motor vehicles without first performing the recall
correction, your facility may be subject to a civil penalty for each such sale.
DEALER RECALL RESPONSIBILITY - All
All unsold new vehicles in dealer's 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 facility 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.

GM bulletins are intended for use by professional technicians, NOT a "do-it-yourselfer". They are written to inform these technicians of conditions that
may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the tools,
equipment, safety instructions, and know-how to do a job properly and safely. If a condition is described, DO NOT assume that the bulletin applies to
your vehicle, or that your vehicle will have that condition. See your dealer for information on whether your vehicle may benefit from the information.
