I voted no for the same reasons khansen expressed. "Life of the vehicle" is way too long. Some might argue that they should be proactive and have a recall to replace all of the "suspect" timing chains, but that's not as nice as some people might think.
First, what is the failure rate? Is it 0.1% of the vehicles or 10%? Makes a big difference in the cost of a recall and the value received (like it or not, a recall is in large part a business decision).
Second, what happens when the chain goes bad? From what I am reading on this board, the engine doesn't get wiped out, so there is noting to be saved by making the repair before it "fails".
Third, why should GM inconvenience a large portion of it's customer base when only a small portion will be affected by this problem (kind of get back to the failure rate question above). Your Acadia is not DOA when the problem surfaces, so people are still scheduling repairs and therefore there is no greater inconvenience to the owner by waiting for failure to make the repair.
Finally, and this is a biggie that no one ever thinks about, every time a GM dealer technician pulls an engine to replace a timing chain, it increases the probability that something else will go wrong as part of the repair. I'm not knocking dealer techs, but every hose connection an wire connection that they have to disconnect and reconnect as part of the repair is another potential failure. Every bolt they have to remove and reinstall is a bolt that can come loose. If the vehicle has made it 10,000+ miles, any assembly issues there might have been have already cropped up. Adding the chance for more assembly-related problems is not something that should be taken lightly. GM probably has enough data that they know roughly what % of timing chain replacements will result in return trips to the dealer for new repair-related problems, so they have an idea what a recall would mean in terms of added customer dissatisfaction.
So..... a recall would cost GM a ton of money. For that spend, they would not make life easier for any of their customer base, but they would inconvenience a lot of them, plus some would be further aggravated by a follow-up repair. This makes a recall a bad idea. As long as GM continues to honor the 5 year/100K power train warranty, I'm not too concerned. It might be nice to bump that up specifically for timing chains on the affected product (maybe 7 year, 150K?), but do we really need a class-action suit for that?
