I was hoping a response was coming soon to this posting. I also have a 2009 Equinox AWD and am experiencing the same exact scenario. My dealer has pursued the elusive issue for 40,000 miles. I have not had any other problems so it is frustrating to go to the dealer and describe this ghost. I recently drove in some strong thunder storms so I had to listen to this for 250 miles, almost drove the wife up a tree. I was almost hoping something would break so we could find this issue but so far nothing. GM will neither deny or confirm that there is a known problem so good luck to us all.

I also searched this problem on the GM site and had a GM associate contact me and had described the problem, they then called a local dealer and found someone that actually knew what the problem was. They instructed me to take my car to the dealer and have it fixed. Rear differential module is apparently the problem...and it is covered under the powertrain warranty!!! That was awesome news to me!! I have had it in to be fixed, but have yet to have a rainy day to see if it worked! The mechanic that fixed it knew what it was because he had the same vehicle and happened to him as well!
If you would like this is the number for the GM person I talked to, she was very helpful and hopefully she can be as much assistance to you as she was to me.
I spoke to Deanna and I called 1-800-263-3777 option 4 extension 2829.
I think if we continue to post the problem should be looked after for everyone.....how can you describe something that only happens in the rain???!!!

I have the same problem. Did that fix your problem? 4th time going back to the dealer.

I haven't had many really rainy days to see, but last weekend was rainy and I am happy to say, so far so good, no noise!! Hopefully that was what was 'broken' and it is now fixed! You did read the earlier post that I made about it being the rear differential module?? Mine was fixed under warranty too, which made it even better!

Hi ecky1 and jdkruz. I'm sorry to report that I no longer own my Equinox. I was extremely upset with the service and run around I received with this issue and chose to dump it. I can tell you that the problem was "fixed" and I use that term loosely. After GM had an engineer come in and take a look at it they determined that the problem was in the exhaust. The theory was that because the exhaust system was so tight, that after driving the vehicle for about a ten minute period and the exhaust heated up, the cold rain hitting the exhaust would cause the pipe to contract, therefore losing it's seal. The dealership installed a Flex pipe and from that day forward the problem never occured again. I could not get an answer as to why this would cause a loss of power and a shake in the entire vehicle though. I spoke a gentleman at a muffler/exhaust shop who specializes in this area and he said he has never heard of exhaust issues causing a loss of power or vehicle shake. So all in all, if you haven't yet had the issue rectified, you can try this. Funny that after there was thousands of dollars spent on warranty work trying to find a solution that it was a $20 Flex Pipe that fixed it. Good Luck!

Funny i found this post. This problem has occurred with my 2009 pontiac torrent since about 6 months from when I purchased the vehicle brand new. I brought it in to dealer as well and they could not diagnose the problem either. I felt as though they thought I was nuts!
Funny as mine is a torrent not an equinox but that is the exact problem. a possible recall??
