My son has a 2007 STS with 3.6L V6. Now has a timing chain issue. I have been doing some research, and think there might be a recall on GM V6 engines re timing chains. Can anyone confirm if this true? And what are the stipulations if any? He is not the original owner, if that matters.

CUSTOMER SATISFACTION PROGRAM
SUBJECT: Premature Timing Chain Wear – Reprogram Engine Control Module
MODELS: 2009 Buick Enclave
2007-2009 Cadillac CTS, SRX, STS
2009 Chevrolet Traverse
2007 GMC Acadia
2009 GMC Acadia
2007 Saturn OUTLOOK
2009 Saturn OUTLOOK
Equipped with HFV6 Engine

Due to the availability of the required calibration, this program is being administered in
phases. This first phase will include the Cadillac vehicles only. You will receive a dealer
message when the calibration and VINs are being released for the remainder of the
vehicles.

THIS PROGRAM IS IN EFFECT UNTIL FEBRUARY 28, 2013.

CONDITION
On certain 2007 model year GMC Acadia; Saturn OUTLOOK; 2007-2009 model year Cadillac
CTS, SRX, STS; 2009 model year Buick Enclave; Chevrolet Traverse; GMC Acadia; and Saturn
OUTLOOK vehicles equipped with a HFV6 engine, under certain driving conditions, and with
extended oil change intervals, the timing chain could wear prematurely and cause the
illumination of the Service Engine Soon light.

CORRECTION
Dealers are to reprogram the engine control module, including the engine oil life monitor.

VEHICLES INVOLVED
Involved are certain 2007 model year GMC Acadia; Saturn OUTLOOK; 2007-2009 model year
Cadillac CTS, SRX, STS; 2009 model year Buick Enclave; Chevrolet Traverse; GMC Acadia;
and Saturn OUTLOOK vehicles equipped with a HFV6 engine
Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the
Required Field Actions section in the Global Warranty system.
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.


Dear General Motors Customer:
This notice is sent to inform you that General Motors is conducting a Customer Satisfaction
Program that affects 2007 model year GMC Acadia; Saturn OUTLOOK; 2007-2009 model year
Cadillac CTS, SRX, STS; 2009 model year Buick Enclave; Chevrolet Traverse; GMC Acadia;
and Saturn OUTLOOK vehicles equipped with a V6 engine.

Your vehicle was designed and built to meet GM's high standards for quality and reliability.
However, we have determined that under certain driving conditions, and with extended oil
change intervals, the timing chain could wear prematurely and cause the illumination of the
Service Engine Soon light. Timing chain wear can be affected by the age of the engine oil and
driving conditions.

What We Will Do:
To ensure that your vehicle will not experience this condition, your GM
dealer will change the calibration of the engine control module, including the engine oil life
monitor, which in most cases will recommend more frequent oil changes. This calibration
change will be performed for you at no charge until February 28, 2013.

What You Should Do:
To limit any possible inconvenience, we recommend that you contact
your dealer as soon as possible to schedule an appointment for this repair.

Parts Information

No parts are required for this program.

Service Procedure Engine Control Module Programming (Cadillac Vehicles)

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) or Tech 2® and TIS2WEB with the calibration update. When using a MDI or Tech 2® for reprogramming, ensure that it is updated with the latest software version.

Use TIS2WEB on or after 1/9/11 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.

3.1. Connect the MDI or Tech 2® to the vehicle. If using MDI, connect to programming terminal with the cable (USB or LAN).
3.2. Select J2534 MDI or J2534 Tech 2® and Reprogram ECU from the Select Diagnostic Tool and Programming Process screen.
3.3. Select ECM Engine Control Module--Programming from the Supported Controllers screen.
3.4. Follow the on-screen instructions.
  1. Capture and record Engine Oil Life information. Write down remaining oil life as a percentage.
  2. 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.
  3. Reprogram the engine control module (ECM). Refer to SI and Service Programming System (SPS) documentation for programming instructions, if required.
  4. Clear all DTCs using the Tech 2® or GDS.
  5. Use a scan tool to reset the Engine Oil Life Remaining back to the original percentage recorded before completing the programming event.

Note: If a programming failure occurs, refer to Engine Control Module Recovery Steps in this bulletin.

Engine Control Module Recovery Steps
• If using MDI, connect to the programming station or Notebook using a cable (LAN). Proceed to Step 5 and then Steps 6-8.
• If using a Tech 2® proceed to Steps 6-8.

Note: Selecting Replace and Reprogram from the Select Diagnostic Tool and Process Screen is REQUIRED because some of the calibrations may be erased from the initial attempt to reprogram the module.

  1. Disconnect the programming device.
  2. Power down the control modules connected to the GMLAN bus by disconnecting the positive battery cable for 2 minutes.
  3. Reconnect the positive battery cable.
  4. Determine which programming device will be used to perform the recovery steps.
  5. Reboot the programming station or Notebook. This is to make sure nothing is in memory.
  6. Reprogram the engine control module. Select Replace and Reprogram from the Select Diagnostic Tool and Process Screen.
  7. Follow the on-screen instructions to complete the programming event.
  8. Clear all DTCs using the Tech 2® or GDS.

Note: Repeat Steps 1-8 above IF another programming failure occurs. If the second attempt to reprogram in unsuccessful when following the Steps 1-8 above, then contact Techline Customer Support Center.

SEQ Programming Sequence ECM/TCM (Buick Enclave, Chevrolet Traverse, GMC Acadia, Saturn OUTLOOK)

Do not attempt to order the calibration number from GM Customer Care and Aftersales.

When using a MDI or Tech 2® for reprogramming, ensure that it is updated with the latest software version.

Use TIS2WEB on or after 02/21/11 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.

3.1. Connect the MDI or Tech 2® to the vehicle. If using MDI, connect to programming terminal with the cable (USB or LAN).

Properly trained technicians have the equipment, tools, 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.

Thanks for your response. I believe his mechanic was aware of this problem, and reprogrammed his engine control module. He said the car seems to be running better, noticed a difference right away. Hopefully, this will remedy situation.

The reprogramming bulletins are kinda old. All that does is change the oil life monitor.

We just had this issue on a 2009 Traverse, 70k miles. SES lamp on..

There is a newer bulletin...The warranty on the timing chain has been extended to 120k on these vehicles. There is a updated timing chain replacement kit. Our was replaced under warranty at zero cost to us. Dealer had the car for a couple of days.

So far so good...SES lamp is off.
