My wife got a letter from GM today about a possible water pump shaft seal leak. Has anyone else received one of these letters?

We got one today on our Acadia. It seems GM has not done anything to fix this issue since it has been happening as far back as 2007. The letter states that if the coolant level is low it will cause the water pump shaft to leak. Really GM? We had to have our water pump replaced on our 08 at 80k miles. Just hope that our 11 will fare better. I guess we will just have to wait and see.

 

I have changed out the transmission fluid on our 11 twice now to get a good quality synthetic in there over the factory fill. I waited until 30k on the 08 and it was pretty dark. At least our 08 didn't have any transmission issues.

We got the letter for our '09. I'm regularly anal about maintaining fluid levels, so haven't visited my friendly local Chevy dealer.

 

A helpful hint from Heloise, though: there is mention in Traverse forum about filling the cold level 2/5ths above the "full cold" mark on the reservoir. Our '09 has the factory tow package, which supposedly includes HD cooling. When new, I added 50/50 dexcool/distilled mix to the reservoir before cold start to that "full cold" mark a few times, and would smell coolant after ~5 miles of driving. I finally decided to stop adding coolant and just watch the reservoir level for a while. It settled in ~1/2" below the fill line and stopped dropping, at which time I also stopped smelling coolant. Hasn't budged from there for the last 3 years. Funny thing is I've never seen the hot level come anywhere close to rising near the fill cap or overflow vent at any time during ownership, so how it got out of there befuddles me.

 

Don't let the smooth taste fool you.

I also got the letter last week so I went out and checked and found the level low so I thought. If you read the side of the reservoir it says "FULL COLD" at the top which is very hard to read so I filled it to there and then started seeing antifreeze spots on the driveway so I said ok the bastards leaking. What I didn't see is where it says "FULL COLD" at the top there is a arrow with a long line going to the bottom of the reservoir where it says" FULL COLD" again Iam cussing now that I had to remove what I put in and it hasn't moved since last week.

I was seeing antifreeze on my driveway from my 09 Acadia before this letter ever came so I took it to the dealer to have it fixed and they are the ones that told me that it was being covered by GM. That's the only time I've ever had that happen haha.
