Recall - Engine Damage When Using Low Octane Fuel
SAFETY
Bulletin No.: 10093A
Date: June 04, 2010
Subject: 10093A - Engine Damage Due to Use of Fuel Other Than Required High Octane Fuel
Models:
2010 Cadillac SRX
Equipped with HFV6 Turbocharged 2.8L Engine (LAU)
Supercede:
The classification of this bulletin has been changed to a Safety Recall. Please discard all copies of bulletin 10093, issued April 2010.
Condition
General Motors has decided that a defect, which may relate to motor vehicle safety, exists in certain 2010 model year Cadillac SRX vehicles
equipped with a HFV6 Turbocharged 2.8L (LAU) engine. If customers use low octane (regular) fuel instead of the required high octane (premium)
fuel as stated in the Owner Manual and on the fuel filler door, the combination of regular fuel usage and aggressive driving maneuvers may induce
pre-ignition. If pre-ignition occurs, the customer may hear a pinging or knocking sound from the engine. If the vehicle continues to be driven after
the onset of this noise, a connecting rod or piston may break, resulting in engine damage, and perhaps engine failure, which would disable the
vehicle.
Correction
Dealers are to reprogram the engine control module (ECM).
Vehicles Involved
Involved are certain 2010 model year Cadillac SRX vehicles equipped with a HFV6 Turbocharged 2.8L engine (LAU), and built within these VIN
breakpoints:
Important
Dealers are to confirm vehicle eligibility prior to beginning repairs by using GMVIS (dealers using WINS), the Investigate Vehicle History
link (dealers using GWM). Not all vehicles within the above breakpoints may be involved.
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. 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
No parts involved - calibration upgrade only
Service Procedure
ENGINE CONTROL MODULE (ECM) PROGRAMMING
Do not attempt to order the calibration number from GM Customer Care and Aftersales. The calibration numbers required for this service procedure
2010 Cadillac Truck SRX AWD V6-2.8L Turbo Page 231
are programmed into control modules via a Multiple Diagnostic Interface (MDI) and TIS2WEB with the calibration update. When using a MDI for
reprogramming, ensure that is updated with the latest software version. Use TIS2WEB on or after 04/01/10 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(R) PSC 550 Battery Maintainer (SPS Programming Support Tool EL-49642) or equivalent to maintain proper battery
voltage during programming.
2. Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for programming
instructions, if required.
1. Connect the MDI to the vehicle.
2. Select J2534 MDI and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
3. Select ECM Engine Control Module -- Programming from the Supported Controllers screen.
4. Follow the on-screen instructions.
3. Using the MDI, and either GDS or Tech 2, clear all DTCs if required.
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.
Claim Information
1. Submit a claim using the table below.
2. Courtesy Transportation - For dealers using WINS, submit using normal labor code; for dealers using GWM - submit as Net Item under the
repair labor code.
Customer Notification
General Motors will notify customers of this program on their vehicle (see copy of customer letter included with this bulletin). In addition, the GM
Customer Assistance Center began telephoning customers of record on Monday April 5, 2010.
Dealer Recall Responsibility - For US (US States, Territories, and Possessions)
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 Program Responsibility
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 program 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.

Dear General Motors Customer:
This notice is sent to you in accordance with the requirements of the National Traffic and Motor Vehicle Safety Act.
Recently you may have been contacted by General Motors about the importance of using the required high octane fuel in your 2010 model year
Cadillac SRX. If you have been notified and the service correction has been performed on your vehicle, please disregard this notice.
General Motors has decided that a defect, which may relate to motor vehicle safety, exists in certain 2010 Cadillac SRX vehicles equipped with a
2.8L V6 engine. As a result, GM is conducting a safety recall. We apologize for this inconvenience. However, we are concerned about your safety
and continued satisfaction with our products.
Important
- Your 2010 model year Cadillac SRX is involved in safety recall 10093.
- Schedule an appointment with your Cadillac dealer.
- This service will be performed for you at no charge.
Why is your vehicle being recalled?
If you use low octane (regular) fuel in your vehicle instead of the required high octane (premium) fuel as stated in the Owner Manual and on the
fuel filler door, the combination of regular fuel usage and aggressive driving maneuvers may induce pre-ignition. If pre-ignition occurs, you may
hear a pinging or knocking sound from the engine. If the vehicle continues to be driven after the onset of this noise, a connecting rod or piston may
break, resulting in engine damage, and perhaps engine failure, which would disable the vehicle, increasing the risk of a crash.
What will we do?
Your Cadillac dealer will reprogram the engine control module. This service will be performed for you at no charge. Because of service scheduling
requirements, it is likely that your dealer will need your vehicle longer than the actual service correction time of approximately 25 minutes.
If your vehicle is within the New Vehicle Limited Warranty, your dealer may provide you with shuttle service or some other form of courtesy
transportation while your vehicle is at the dealership for this repair. Please refer to your Owner Manual and your dealer for details on courtesy
transportation.
What should you do?
You should contact your Cadillac dealer to arrange a service appointment as soon as possible and always use the required high octane fuel in your
vehicle.
Do you have questions?
If you have questions or concerns that your dealer is unable to resolve, please contact the Cadillac Customer Assistance Center toll free number for
more information. More information about your vehicle can be found at the Owner Center at www.gmownercenter.com
If after contacting your dealer and the Customer Assistance Center, you are still not satisfied we have done our best to remedy this condition
without charge and within a reasonable time, you may wish to write the Administrator, National Highway Traffic Safety Administration, 1200 New
Jersey Avenue, SE., Washington, DC 20590, or call the toll-free Vehicle Safety Hotline at 1.888.327.4236 (TTY 1.800.424.9153), or go to
http://www.safercar.gov.
Federal regulation requires that any vehicle lessor receiving this recall notice must forward a copy of this notice to the lessee within ten days.
