STS..AWD reliability compared to RWD
1 - 20 of 33 Posts
AWD not bad in before 1badcadsts says the 3.6 is rubbish. I did test drive the 3.6 with the AWD and was not a fan of it thought it was underpowered, I like the 3.6 with RWD it behaves a lot better and feels like I have the power. no real difference in gas mileage between AWD and RWD
I don't say its rubbish... I say its an oil drinking timing chain jumping PIG... Oh so does GM for that matter, they just weren't nice enough to include every 3.6 so sorry 05-06 and 10+ owners... you're screwed.

Additional vehicles have been added to this Special Coverage. The service procedure has been revised to include reprogramming of the ECM, if applicable. If a vehicle is presented and the timing chain replacement is not required, dealers are to reprogram the ECM if it has not already been reprogrammed. See the service procedure for details. This reprogramming is covered under this Special Coverage. Please discard all copies of bulletin 11340B, issued July 2012.

ConditionOn some 2007 model year GMC Acadia and Saturn OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, and STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn OUTLOOK vehicles that are equipped with a 2.8L/3.6L V6 engine (LP1/LY7/LLT), under certain driving conditions, and with the vehicle's original oil change intervals, the timing chain could wear prematurely and cause the illumination of the Service Engine Soon light.
Special Coverage AdjustmentThis special coverage covers the condition described above for a period of 10 years or 120,000 miles (193,000 km), whichever occurs first, from the date the vehicle was originally placed in service, regardless of ownership.
Dealers are to replace the timing chain. If a customer brings their vehicle to the dealership and it is determined that the timing chain does not require replacement, dealers are to reprogram the ECM with updated software, if applicable. Refer to the Service Procedure contained in this bulletin to determine if reprogramming is required. The repairs will be made at no charge to the customer.
For vehicles covered by Vehicle Service Contracts, all eligible claims with repair orders on or after February 17, 2012, are covered by this special coverage and must be submitted using the labor operation codes provided with this bulletin. Claims with repair orders prior to February 17, 2012, must be submitted to the Service Contract provider.
Vehicles Involved Involved are certain 2007 model year GMC Acadia and Saturn OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, and STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia, and Saturn OUTLOOK vehicles that are equipped with a 2.8L/3.6L V6 engine (LP1/LY7/LLT).
Important: Dealers are to confirm vehicle eligibility prior to beginning repairs by using the Applicable Warranties section in the Global Warranty Management System.
It should be noted this "TSB" was issues after the TSB that was issued to dealers to CHANGE the oil life monitor algorithm to LOWER the oil life monitor and reduce the "life" of the oil so owners were more likely to service it and notice a low oil situation before oil deprivation stretched the timing chains.....

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.
IT SHOULD ALSO BE NOTED THAT REGUARLESS OF WHAT THESE TSBS SHOW ALL YES ALL GM 3.6S DI AND NON DRINK OIL (JUST AT VARYING LEVELS DEPENDING ON THE PREVIOUS OWNERS MAINTENCE OR LACK THERE OF) AND DUE TO THIS CAN CAUSE PREMATURE WARE AND FAILRE OF THE TIMING CHAINS...
Personally Ill buy a northstar and pay the 2 bucks more to fill it with premium fuel thank you...

Dear General Motors Customer:
As the owner of a 2007 model year GMC Acadia or Saturn OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, or STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia, or Saturn OUTLOOK, your satisfaction with our product is very important to us.
Recently, you took your vehicle to your dealer to have Customer Satisfaction Program 10287 performed. Your dealer reprogrammed the engine control module to prevent premature wear of the timing chain and the illumination of the Service Engine Soon light. Further analysis has shown that the reprogramming may not fully correct this condition for all vehicles; we, therefore, are providing you with additional protection for the timing chain.
What We Have Done: General Motors is providing owners with additional protection for the timing chain. If premature wear of the timing chain occurs on your 2007 model year GMC Acadia or Saturn OUTLOOK; 2007-2009 model year Cadillac CTS, SRX, or STS; 2009 model year Buick Enclave, Chevrolet Traverse, GMC Acadia, or Saturn OUTLOOK vehicle, equipped with a 2.8L/3.6L V6 engine, within 10 years of the date your vehicle was originally placed in service or 120,000 miles (193,000 km), whichever occurs first, the condition will be repaired for you at no charge. Diagnosis or repair for conditions other than the condition described above is not covered under this special coverage program.
Do not take your vehicle to your GM dealer as a result of this letter unless you believe that the Service Soon Engine light has illuminated due to timing chain wear.
What You Should Do: If you believe that your vehicle's Service Engine Soon light has illuminated due to timing chain wear, repairs and adjustments qualifying under this special coverage must be performed by a General Motors dealer. You may want to contact your GM dealer to find out how long they will need to have your vehicle so that you may schedule the appointment at a time that is convenient for you. This will also allow your dealer to order parts if they are not already in stock. Keep this letter with your other important glove box literature for future reference.
Reimbursement: If you have paid for repairs for the condition described in this letter, please complete the enclosed form and present it to your dealer with all required documents. Working with your dealer will expedite your request, however, if this is not convenient, you may mail the completed form and all required documents to Reimbursement Department, PO Box 33170, Detroit, MI 48232-5170. The completed form and required documents must be presented to your dealer or received by the Reimbursement Department by July 31, 2013, unless state law specifies a longer reimbursement period.
If you have any questions or need any assistance, just contact your dealer or the appropriate Customer Assistance Center at the number listed below.

So how about you tell me how the 3.6 ISNT junk?
I bought a car that had all it's maintenance done by a Cadillac dealer and the dealer proved it to me when I bought the car and no drinking of the oil, second oil change today since buying the car 3,000 miles apart with synthetic oil too both times.
Pull your air intake tube. Post a picture inside the intake.framedforlife said:
I'll accept your apology once you do.
my apology!? Really you will owe me one when I prove your wrong.
Where are you located so we settle this like men.

·Of course you are entitled to your opinion, but where do you get your information to make a statement like this? BTW, you should check your spelling before you post.
Posting all that from a phone isn't exactly easy. My apologies for not being 100% accurate in spelling.KRSTS said:
I would say GMs tsbs and extended coverage program show it to be a fact not an opinion...
----------
Getting a little bent aren't we kiddo?framedforlife said:
Go on. Pull your air intake open the tb and show me how "clean" (completely soaked in oil) it is. Then proceed to tell me how it doesn't use oil...
Meanwhile I'll share this photo from a 2005 SRX with 65k miles and oil changed every 5k. I know this as it belongs to my sister and I service it...
I also service a 2009 GMC Acadia 2010 SRX 3.0 and a 2009 CTS 3.6 DI for my regular customers. All of which have the intake manifold painted in oil...
And it's Pittsburgh, PA. I insist you stop on by anytime and I'll be happy to show you 1st hand how thirsty the 3.6 is.
All i asked as the OP was what the difference is between 2WD & AWD with fuel economy and maintenance/breakdown/reliability of the AWD system itself.
In other words, is it a cash cow to go for the AWD.
Is it the same system as the SRX ?

Sorry I was dragged into it and felt the need to clarify some ignorant responses.PiperMike said:
It's the same system as Gen 1 SRX fully mechanically controlled.
Yes of course it is less fuel efficient due to both weight and mechanical drag.
If you live in a bad climate that experiences snow or even just a lot of rain the awd is well worth it.
Just a little worse mileage (like 1 MPG) and probably a little stiffer ride with AWD.
I think they have come out with an updated camshaft cover to improve PVC design to prevent excessive oil buildup in the intake duct. Maybe check it out and see if the bulletin applies to your specific models. I don't think it goes back to 05 but I believe 09 is included.1BadCadSTS said:
Get tied on.PiperMike said:
It's a Cadillac. Expensive repairs are a roll of the dice you take. Doesn't matter awd or rwd.

It was revised and reduced it but the design of the engine makes it impossible to prevent it.Dino1SG said:
