I found this on "The Cobalt SS Network Forum"
I don't think that they will mind it being posted here
BTW, had no problem with mine during the 1st oil change,as mime was built in Feb., but something we need to be aware of just in case
First Oil change LNF TSB

Just a heads up for those who change their own oil , keep an eye on the drain plug . This applys to cars built between certain build dates ,so you might want to check yours .
#PIP4415: Heli-Coil Moves When Removing And/Or Installing Engine Oil Drain Plug - (May 8, 2008)
Subject: Heli-Coil Moves When Removing and/or Installing Engine Oil Drain Plug
Models: 2008 Chevrolet Cobalt, Cobalt SS, HHR, HHR SS, Malibu
2008 Daewoo G2X
2008 Opel GT
2008 Pontiac G5, G6, Solstice, Solstice GXP

The following diagnosis might be helpful if the vehicle exhibits the symptom(s) described in this PI.
Condition/Concern:
When removing or installing the engine oil drain plug, the heli-coil may come out of position. In some instances it may come out with the drain plug. This is the result of an issue with the original heli-coil, not the oil pan.
Recommendation/Instructions:
If this concern is encountered, remove the oil heli-coil and install a new one using a M12 x 1.75 heli-coil from a local supplier. The instructions from the heli-coil supplier should be used. If necessary, several heli-coil suppliers can be located on the internet by entering "heli-coil" in the internet browser and clicking search.
Please follow this diagnostic or repair process thoroughly and complete each step. If the condition exhibited is resolved without completing every step, the remaining steps do not need to be performed.

I wonder why there is a heli-coil there in the first place sounds like they ran a bunch of over size pans.Then repaired them rather then scrap them out and save some money.That may be the reson they are only in a certain build group.
GTOMIKE, I had the same first thought as you did, Then I was kinda thinking that this was a good idea for us (Jiffy Lube Kids Overtightening and stripping out the Oil Pan???) I could be way wrong here...
I think the reason that they have a helicoil on the drain plug hole is because it has a die cast aluminum pan. The aluminum threads would strip out or cross thread very easily. The helicoil insert permits you to have a much stonger steel thread to tighten your plug into. I'm sure this is the engineering behind it...
I'll bet the ones that have been failing where not tapped correctly or were installed incorrectly.

Thanks for the post. My first oil change is compliments of the dealer, so I'll remind him of the TSB then.
I like the unambiguous ambiguity in the TSB where it says...

That quote is in all TSB's and PI's, same as the bottom wording "To be used by proffessional service technicians". Just more legalistic wording. When someone wants to have a copy of a bulletin I delete all of that.
This is actually called a PI, which is preliminary Investigation. It's not a TSB until GM legal makes it one.
