Thats wierd as the techs I talked to local sure know alot about them as they've done so many.

Could it be a climate thing?? Here we have harsh winters so maybe the cold has more to do with it. Seems by 40,000 miles it can be quite common to have them replaced. Every week on the Acadia owners forum someone posts a new story its seems about getting the chains replaced.

Going to test drive that new ford explorere again and compared vs. the Acadia!
B whatever vehicle you like.....just make your decision on true facts and not nonsensical dumped without fact.

Sorry if that is offensive to those wanting to propagate a rumor to sway sales toward brands other than GM.

The 3.6 v6 is a nice powerplant.
 
Oh look, from Ms. Barb Samadzich, Vice President Powertrain Engineering @ Ford while addressing the 36th API Automotive / Petroleum Forum on 20 April 2010 we have this. < At the time - since promoted >

Emphasis on the first item (in red) is from Ms. Samadzich & Ford.

Hang on -

What Help is Needed From the Petroleum Industry ?


Lubrication:

• Deliver consistent engine oil quality conformance to assure adequate oil life – Ford will have 10,000 mile oil change intervals for 2011MY < Original author's emphasis >

• Develop lubricants for new fuel efficient powertrain technologies to enable:

•Higher temperatures and higher load duty cycles

•Lower ash levels -- protect against engine pre-ignition

•Faster warm-up

•Flatter viscosity index --same viscosity over wider temperature range

• Work toward global engine oil specifications

• Develop new low-viscosity gear oils to improve transmission efficiency

• Research next generation friction reduction ideas (Engine and Transmission)
Nice to see GM was once again, ahead of the curve with the Deros spec programs.

- and this......

What Help is Needed From the Petroleum Industry ?

Fuels:

• Narrow the range of gasoline quality (i.e. volatility) in the marketplace – current trend is widening

• Trend to higher octane / cetane for customer benefit on new-technology engines

• Eliminate metallic additives in gasoline worldwide :eek:

• Expand bio-fuel research (E20-E100 and B20+) to achieve increased performance, improved combustion and cold start satisfaction for global customers

• Continue cooperation on fuel standards (worldwide)

• Improve countermeasures for fuel injector tip deposits (all global markets)

Tier 1 fuel and GM deros - FTW.

Lot's of interesting info @ the link in terms of how Ford sees the future unfolding.

Includes some massive PT adoption rate errors as well - which if not addressed correctly and effectively, is going to sink their boat.

I'm not following you here??

I'm not trying to "proagate a rumor" or whatever you want to call it. After I did the old net research I thought I better get first hand info. So I talked to GM guys, "went to the horse's mouth" so to speak. They are not making this up and this is nothing new. Every brand will have a vehicle that has certain issues with things. Back when I pulled wrenches and was current with everything on the road I could rattle off what were trouble spots on certain makes and models no problem.

I'm not an anti GM guy like your trying to lable me as. When my father bought a car 90's I told him buy a Buick Regal with the 3800. Those engines were great and got great fuel mileage! That car was trouble free one of GM's better cars at the time. The old throttle body fuel injection on pickups in those days was very trouble free and cheap to maintain. Just a couple examples I could go on for an hr. lol!
 
When you speak to a GM technician ..yours is supposedly fact...and ..When I speak to a GM world class technician who is a personal friend of mine for over a dozen years ...he tells me there is no problem..and when I repeat what I heard on this thread......I'm full of it? or bad mouthing you?

What can I say except where are your facts?

what percentage of vehicles have this issue and how does it compare to competitive malfunctions of their timing chains..?

Sorry if that offends you. That is not my intent..


btw..just between you and I continuing TO POST ON this thread...this can possbly be construed by you as a TEN THOUSAND POST THREAD ON THIS SUBJECT..! (JOKING OF COURSE) and somehow that gives the issue legamacy (SP)

I'm not offend one bit. Actually I wish someone could provide facts or some sort info from GM or something.

By the way what's a "world class GM technician" anyway? Some sort of GM training?? I'm not a "world class tech" by no means but I know my way around a car somewhat still LOL! I didn't disagree with your friend the tech. I threw the question out maybe it has to do with climate or something. Cars in the south have different issues sometimes then cars in the northern climates.

I know what your saying all engines will have a failure rate on certain components to some degree. I haven't found any other newer SUV with this sort of issue like the Lambada's do other then Suzuki's. Not saying its not possible, just saying I haven't noticed anything yet and I have looked.

I didn't start the 100's of threads on the Lambda owners forums either! If you note I joined this forum in Aug. when I was looking for info on my Pontiac with a weird drivability issue. Actually I should post that again see if anyone can help me out on that one.
 
I'm sure you get an answer asap. "No trouble. Never has been, and never will be. You must have maintained it improperly."

Caddy should have some other information from his guys also. He is a pretty straight shooter, so I wouldn't disregard it.

BTW, oil starvation could be more prevelant in cold climates. New thin oils do not leave much of a residue, so you could have a "dry" situation at start-up, which would be irritated by all other lubricants also being "cold."
 
Good. I'm glad I haven't offended you. I 'm glad we have this forum to discuss this type of stuff..

fwiw..My understanding of a GM world class techician is one that takes all their classes and its the highest level of GM techician skill sets..

All I am suggesting is that if the 5 year 100,000 drivetrain warranty is not good enough and someone is considering a GM product ...then just buy the extended GMPP warranty for the time term they are going to own the vehicle for.

Its an option should you feel you need this extra security.

Good luck in deciding what brand of product to buy and if the Ford Explorer better suits your concerns and needs. Go for it. Seems it just one truck of the year at detroit so I'm sure its a great choice.

I hope it has the better durability that your suggesting ...

Personally I feel the GM product line is favorable from a durability standpoint but we can agree to disagree. (I am a satisfied GM customer for so many decades that I am somewhat biased towards there product line even over the impressive new Ford Explorer)

One thing I know for sure is I'm tired of looking at these darn SUV's and talking to salesmen!! Personally I like the looks of the Acadia better but the wife likes the Ford interior. So we'll see!
 
All good information but you might have meant an 09 Traverse with an 08 build date? That is there is no 08 MY for the Traverse
Over on the Traverse forums this has been discussed at length also and it seems the problem was with Lambdas built in 08-09. I believe it was only owners that had 2008 and 2009 build dates that were having a problem and that GM at some point late in 2009 changed the chains.

Would really love to get someone to confirm that they did in fact change the chains in 2009. I have an April 2010 build so I'm hoping I'm in the clear but people who did have this problem, had the chains fail relatively early.:( Anyone from GM out there that can answer this question???

There have been few 09 builds that I have seen (on the forums) with this problem.
 
If GM has really changed and wants to do right, they should extend the powertrain warranty on these engines to 10 years/120,000 or 10 years/150,000, at least for the timming chain and the related components. I think this would also take off the heat for a recall. This would be the right thing to do and give their customers confidence. The main reason I bought my Traverse was because of the 5 years/100,000 powertrain warranty although I think it should be at least 7 years or maybe even 10 to match Hyundai, Suzuki and Kia. Unacceptable that in this day and age they are having this issue. GM are you listening???????

The scary part is that most people probably do not have enough time or mileage to have a problem, that's what worries me. Look over in the Cadillac forums are we are not seeing a bunch of cars with 30K, 40k+ that are staring to have problems.

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.
 
Basically - change the oil more often.

I wonder why 2008's were left out of the campaign? Ive seen a few 2008 Enclaves with Timing Chain problems on the Enclave forum.

WOW!!! I mean FREAKING WOW!!! :clap::clap::clap:
:bounce:

Its like I wrote it! Could someone from GM corporate acutally be monitoring these threads? ;)


WAY TO GO GM!

This is
1) The Right thing to do,
2) The cost effective thing to do and is
3) SMART VERY SMART!

This is something that we would have NEVER seen from "old GM"... definately a glimmer of light.
 
One question I have.................... How can a vehicle with 4000 miles on it, not be "maintained" properly?? Did they run it in the Daytona 500, to abuse it that badly, in 4000 miles??

So, they are recalibrating the oil life monitor.

Hmmmm.................

I can see where this is going, however. Owners had better keep real good track of their oil changes, or have them all done at the dealership. Otherwise, in the future, you may see warranty claims for timing chains being denied, due to "abuse."

I am not excited about this prospect, as I enjoy maintaining vehicles myself. Of course, I have the cylinder lock recall to deal with first.
