If you have AWD maybe transfer case? If you have V6 maybe timing chain issue?

Thanks. I decided for $55 to take it to a Cadillac dealer to have them diagnose the problem. Will know soon.

 

How did the diagnosis go? Let us know if we can check into anything further for you on this.

T-case is my vote.

 

Yeah I'm betting on transfer case as well

 

Sounds exactly like the transfer case.

 

I have a 2005 doing the same thing. Take off from stop at heavy acceleration and its a popping ratcheting sound just for a few seconds. The driver side front brake is also squeaking when I turn the wheel and the brakes, rotors etc. Are new. Let me know what you find out I was told the axle.

 

Transfer case. Just did mine. Find somebody other than dealer to fix as it is expensive. Get transfer case from on line GM parts dealer and a transmission shop can install it.

 

SOunds like gm has given us all the slip here!
What you are hearing is the transfer chain slipping on the drive sprocket inside of the transfer case. THIS HAS RECALL WRITTEN ALL OVER IT!!!! but gm told us to get bent. I have the same problem in mine and will never in my life spend hard earned money on a GM. I have talked to so many others with the same problem! Gm got wind of this and started using a new BETTER chain to correct the problem but never made good on all the "defected " ones that got by and started slipping at 50,000 miles.
Cobra trans in fla can help you out.


Heres what i found.....


All wheel drive versions for both engines come with the Borg Warner BW-4476 transfer case. The BW4476 for the SRX originally came with the CT-HV-080 chain and later superseded by the CT-HV-095. The 095 was developed for the Cadillac 265 and 295. Our understanding is the 095 chain is a bit stronger than the 080 chain.

A common problem arising with this unit is a stretched chain. If caught and fixed early enough the damage should be limited just to the chain.

The common symptom is a popping noise coming from underneath the vehicle, especially when at a dead stop and speeding up. The noise could be heard when the vehicle is under a heavy load.

The important thing to keep in mind is to replace the chain as soon as you suspect a problem so the sprockets do not get ruined, thus increasing the cost of the repair.

 

Here's a thread on DIY transfer case chain replacement... which may be your problem

Nice write-up and research 2005, you nailed it. But don't stress getting it fixed immediately when the noise is first heard and detected. My '04 v8 northstar got so bad it'd barely start moving from a complete stop on ANY incline, where I was finally forced to quit driving it until fixed. I ordered the Cobra chain replacement and did the repair to find the sprockets were all still in PERFECT condition. Yes, the root cause is the OEM chain is weak and stretches out at around 30-50k miles and more than likely won't hurt your sprockets.... The link I posted above is of JD2004 writing up an excellent step-by-step guide to DIY. I completed the repair a few yrs ago and have put almost 75k miles on our new chain with no more issues whatsoever. I even punch the accelerator quite often. Great pictures are included in the link as well to help anyone who has 8-12 hours to do this work themselves and save a ton of money. Yes, GM really shot themselves in the foot on this one by not doing a much needed recall. I'm certain they lost A LOT of good customers in denying this design flaw. Only serves to confirm how GM upper management are complete idiots... I love cadillacs but this is a real shame!!

 

I have a 2004 V8 AWD, and am getting the same problems. i am not too thrilled about it. I would expect a little more from a Cadillac. It is looking more and more like i will have to make the switch to Japanese when the time comes, seeing as how my other vehicles have gone that way as well.

 

Cause Japanese cars never break :bigroll:

 

Yup. All cars breakdown it's a fact of life. It's just a rage thing "I'm mad at you so I'll threaten to buy something else next time" let's face it this is a car that is 8 or 9 model years old and newer revisions of this model were updated to fix this issue. Also this was the first year of this platform that needs to be taken into consideration. The srx was completely new with most interior things borrowed from CTS that was new as well just 1 year prior but drivetrain wise completely different than the CTS.

A new platform is expected to have some issues in its first year.

 

Repaired the problem with the chain myself. Wasn't as bad as I thought. I also spent the xtra money and replaced the sprockets as I didn't want to do the job again.Got the chain on Ebay and the sprockets from Cobra. Every car has its own little quirks. Friend of mine has an S-10 pickup with 258K on it with original engine and trans. My son has a VW GTI with 90K and is a nightmare! Buying cars is a crapshoot!

 

I'll add to the chorus of people saying, "WITHOUT A DOUBT, IT'S A STRETCHED TRANSFER CASE CHAIN"
Been there, done that. Yet another GM engineering design flaw we are all left to contend with.

No its not.
This would be on Borg-Warner as it is their transfer case and chain used.
Borg-Warner clearly over-rated the chain used in the transfer case for power handling... a more durable chain was used in later years.
The BMWs that use the same AWD transfer case have a weaker engine and don't stress this component as much as we do.

 

GM engineering decided the unit was beefy enough to use in the SRX application. Whether Borg-Warner over rated the chain, the chain was manufactured inferior to spec, or GM specified it's use in the SRX when it shouldn't have, I don't know. Regardless of who is at fault, I still blame GM for not taking care of their customers with a recall on an obviously defective part/application that does not perform as it should.

Funny

If this is so prevalent to require recall why in the STS, which shares the same driveline, this problem unheard of....

 

...not good to hear...hopefully your issue is fixed...

 

Bad, could it be the weight difference in the 2 cars. I think the components are rated on weight and HP/torque for application.

 

Honestly the cars are really close in weight...
We are talking about 200lbs which could easily be covered by having 2 occupants in the STS all the time.
Now you can tow with the SRX where you shouldn't tow with the STS so perhaps this relates.
Or people overloading the cargo area on the SRX exceeding the cargo weight limits.

Here are the first gen specs:

Exactly

Weight is NOT a major factor here. Im also willing to bet more STS owners beat their cars then SRX wagon owners...

 

2005 V6 purchased @60k mi from original owner. Now at 150k mi. Transfer case chain went south at around 90k in 2011-ish if I am remembering correctly.

 

Well then to be honest your not GM's customer and they don't own you a fix, a used car failed at 90K 6 years and 2 owners after it was made.

I bought a 2010 X5 with 90k on it and my primary urea tank failed 2 days after I bought it, the 09's had a recall but my year was not included even though it was the same issue. My course of action? well I bought a used car and I suck it up, fix it and move on.

I'm sort of surprised none of our SRX owners have tried to sue their wives for ugly kids or their parents if they go bald, life is not fair...

 

SO... Rom... What did Cadillac find in your $55 Diagnostic?

Mine did such a while back, and in my case, it was a heat shield for the Cat, clanking against the frame.

 

If you bought your car at a GM dealership, you're a GM customer...I did...

Recalls have nothing to do with who purchased the car from whom. The chain fails too frequently on these cars. Whatever the reason may be, regardless of who In the parts supply chain is at fault, GM should have recalled them for the issue.

 

GM must have dumped Rom and his SRX out to the desert, and left him with no gas, or internet, or cell phone access.

 

Then again maybe he fixed his transfer case issue 2 years ago when he opened the thread. the thread was reborn twice since then.

 

I just noticed the same problem on my wife's 2011 SRX with 39k. Not happy. Will be taking to the dealer tomorrow and hopefully this is cover by the manufacturer's warranty.
