GM will decline warranty if you put in the additive

[slow35th]

Yeah and aftermarket exhaust will void it also.....You mean like the GM endorsed Corsa? These guys are a trip.

Also email David Caldwell.

david.caldwell@gm.com

If we don't start making some noise now ALL our warranties will be voided at the whim of a dealer or district service rep'.

If you complain about the wheel hop you must be an aggressive driver.
If your tires wear poorly, you must be an aggressive driver.
If your clutch or slave cylinder fails you must be an aggressive driver.

Leave a message, send an email but let's get off our collective keesters and put a stop to this diversionary tactic by GM. The issue is not abusive driving, THE ISSUE IS A POORLY ENGINEERED VEHICLE. PLAIN AND SIMPLE.

Before you all go e-mailing and calling everyone... Let's get organized to make it less thin.....

In the meantime, everyone post your experiences HERE (not on the other thread) and I will find a way to get this all together and to the correct people...

Everybody -

I've had my diff REPLACED but not under warranty (they blamed it on an accident) because of the failing "vaporware" limited-slip diff due primarily to lack of additive.

How can I help?

[ace996]

As requested I copied my post...

Fellow V-pilots,

My dealership found my inner rear halfshaft broken and a wornout front diff bushing. They ordered a new diff...

Service manager also heard "clunk" while de-clutching, and wants to put in a new tranny....District Service Manager needed to approve, came down and looked at my car. He pulls out a tire-wear instrument and says that I have abnormal tire wear at 4K miles...about 80%...on my rear tires. Perhaps I drive too aggressively he says to the dealership service manager. (I wonder if he knows that the V's tires are shaved from the factory???)

The DSM tells the service mgr to NOT order a new tranny, that they would try to fix my current one and THAT WOULD BE THE LAST REPAIR TO MY TRANNY. He thinks I abuse the car and that the problems are "driver induced". I very much dislike having to defend myself to someone who has never met me...simply because he has a tire-wear gauge and may know how to use that tool correctly.



So, because someone hasn't read the TSBs, you know the one that talks about "parade" driving...that the clunk is normal, I may lose my warrantee on my transmission...after they take the thing apart!!!!!! Get this...they don't even have the required tooling to accomplish the job...they need to order the tools!!!! And then..after someone who never disassembled this tranny before puts it back together...they'll NEVER honor a tranny warrantee claim again!!!!!



I think I may need to call the Northeast Region Manager, as the District manager may not "know the V as well as he should", certainly not enough to VOID my drivetrain warrantee for something that a TSB says is NORMAL.



Now, I'm usually a very rational person but I am quite upset at this. I will speak to the DSM tomorrow and hopefully have a proper resolution of my V's issues. My V has less than 5K miles, I don't drag-race, and it requires about 15% of the purchase price of the vehicle in repairs???? Should I have issues with the DSM, I'll need to speak to someone higher....any recommendations?? I figure the Regional Service Manager would be the one...any contact info????



Thanks,

ace996



Seems I'm 25% into the 30day lemonlaw, I hate to say it but if I hit 31days...I'm leaving GM for good. I love this car, but not enough to feel like a criminal when I bring my car in for service.

[ahahnu]

I'm actually scared. I have to go in for the whinning, and someother stuff. I don't want them to hold my car if they need to replace and its on back order. CVP, if I remember correctly, didn't you post when you were in for rear problems on your last V, didn't they give you a deal on your second one? From my experience in retail you need to go as high as possible. I know you have gone up the corporate ladder etc. What about the owner of the dealership? Can you get to him. I know its is a service issue, that is where they make their money, and you have bought atleast two cars from him. I dunno if it will work, but maybe its another way to go for you.

[ace996]

Who is David Caldwell at GM??? and do you have his phone number???

[ctsvett]

I REPEAT... NOBODY CALL ANYONE AT GM YET... WE WILL LOOK unorganized and have less effect... I am attempting to contact the right people and direct them to this thread... SO, everyone post your experiences HERE and wait until at least next week before you call. I will post and update soon!

Everybody - trust in the force (aka Reed).

Keep us posted. I wonder what will happen when/if my diff fails again? Seems to be a pretty happy camper with 550hp or so, aggressive driving (per ace996's experience with the DSM), and aftermarket synthetic fluid...but who knows.

[ctsvett]

It would help me if everyone put their comments (rants) in the following format:

(examples in "(")
Name: (CTSVETT)
Dealer: (Crappy cadillac)
Contact at the dealer: (Bob Dumbass)
Warranty Claim denied: (yes, they wont replace my diff)
Innaccurate claim made/mistake: (the CTS-V does NOT have a limited slip and they did not put in the Friction modifier. )
Other notes: (They never get anything right. I want to hurt them badly...)

[CadV]

I can only share my experience...

I have 17,500 miles on my car and I changed all my fluids to Amsoil after 1000 miles. Initially I put the slip lock in there but after researching the additive I determined it wasn't necessary.

I have been running 10000 miles with out the slip lock with no problems.

Some diff lubes such as Redline have friction modifier in it already. I am sure that Amsoil does also. This is a quote from the link you provided would explain why you have not had problems without the additive:

AMSOIL 80W-90 SYNTHETIC GEAR LUBE is compatible with most limited slip differentials. If limited slip differential chatter occurs, add AMSOIL Slip-Lock™ friction modifier additive.

Didn't even notice that :P

James Zawacki
Not denied but repaired improperly - NO ADDITIVE
James Zawacki claimed vehicle does not have a limited slip rear differential and, therefore does not need the additive. Once I esculated this to Corporate, they allege abusive driving.

Hey, Reed, I think you and I go to the same dealership.
My dealer has been nothing but good and my regional has been very forgiving. However, it took em 21 days to get a gas tank for the V....
