10-03-09-001: Vibration/Pulsation/Thrumming TSB (FIX)

[Rawyzf]

I get some vibration on the wheel....so I'll bring this up at my next oil change! Thanks for the info.

I wonder what they are going to say about doing the work though. I see that they have to remove the right side exhaust manifold and cat. Well....many of us have headers, so I wonder if that will end up being an issue.


EDIT: Also, wondering how these softer engine mounts will effect engine/driveline lash? From past experiences with Mazda's, everyone usually upgraded to Hardened Poly Mounts to elimiate the lash and deliver the power to the wheels more "crisp" for lack of a better word at the moment .

Typically if you have aftermarket parts that need to be removed, most times you'll have to pay the book labor to have them removed. It's the dealerships decision.

I can't get my dealer to work with me. They say the TSB is extensive and will cost more to run than they will receive in reimbursement from GM.

Also, the regional rep apparently has final say over whether they'll provide the damn prop-shaft.

Overall, it looks like GM is creating a bunch of 2nd class citizens out of we G8 owners...having to go "begging" for part replacements that GM knows are bad, or they wouldn't issue a TSB in the first place.

Standard BS line from the dealer: "They all make that noise, so it's not a defect". I want to drive my G8 through their dealership plate glass!

Any ideas on how to convince a dealer (who admittedly has the best techs in my area once you get their attention) to work with the TSB's instead of pushing we "seated in coach" Pontiac owners around? I'm too old for this sh*t!!

Call Pontiac Customer Care. Be nice on the phone, those folks are there to help you.

Thanks Mom,

No wonder it took awhile to find a fix. They had to write an entire encyclopedia!

Looks like a 4+ hour potential here... I doubt it will take them that long to go through the process... sounds like they are a wind down store.

I took my car in today.

They claimed all they did was indexed the driveshaft again. It appears to have eliminated the vibration problem at last.

[familycaronROIDS!]

Hey my car does vibrate when I am on a smooth highway driving on normal speeds between 60-75. I am gonna take it in at my earliest convenience. I am just gonna have to tell them not to touch my ECM & TCM.. Or I will kick their butts!!

Update:
Car in service for 3 days now. They've flashed BCM, TCM, etc.. with new firmware (check GMTIS site...it will tell you if your car has available update for the ECU's):

So far, had to get into scream-fest at service manager, because he's insisting now that there's no road good enough in the area to induce the driveshaft vibration. He called tech line at GM, they told him to put the vibration sensors on the car and run with it...waiting to hear back.

If not this dealer, then the next. I know there's an issue, based on the description in the TSB (exact match to the symptoms...phasing vibration, booming noise, etc...) but this dealer is jerking me around, telling me how much time and money they'd have to put into my car just to accomplish the items in the TSB.

Bad vibes all around.

Will post again when I hear back from dealer today.

Would it be worth BUYING the new driveshaft from GM if the dealer's refusing to run the TSB? They're giving me the BS about "They all do it, so it's a design issue", etc.

Can't understand why they won't take GM's money for the repair!!
