GM will decline warranty if you put in the additive

CVP33 · #1 (**permalink**) 08-18-05, 09:50 PM

I need everyone's help.

GM corporate is demanding that I return my CTS-V to Colonial Cadillac to be inspected by a technician. GM claims that Getrag is incorrect. Karen Uthena, from the "Executive Office" asserts the following:

#1 - The CTS-V does NOT have a limited slip differential
#2 - The rear differential does NOT require a friction modifier or additive
#3 - If you are having problems with your CTS-V's rear differential is could be due to aftermarket parts such as exhaust, headers, CAI, etc.

Now obviously I'm not going to return my CTS-V to Colonial who has once again botched my repair, nor do I feel the need to have a tech "look" at my car. The question is simple. Do I need the additive? GM claims NO, Getrag claims YES.

TODAY IT'S MY WARRANTY TOMORROW IT'S YOURS.

If you want to help, call Karen Uthena at and ask for a definitive answer as to whether or not YOUR CTS-V needs the additive. How can one dealer say yes and another say no. If you're wondering why the rear differentials blow early I think we just found out.

CALL TODAY AND LET GM KNOW WE'RE NOT GOING TO TAKE THIS
ANYMORE.

I really need everyone on this one.

Is this a joke? Tell me it is, please. (I know it isn't

)

Of course it's an L.S.D. and needs the friction modifier. Hell, the tech at my Caddy dealer is thinking about upping the dose of the FM on his own diff to see if it will get rid of the parking lot turn groan that started at 2k.

I really can't believe this is even up for discussion.

Wow. One V owner gets a broken aftermarket shifter replaced + expenses all picked up on Cadillac's bill and you're getting this BS.

Looks like your dealer has it out for you and your god forsaken gearhead modifications and is using this no additive as a cop out.

Colonial has it in for all V owners. I don't know if everyone caught Fuggetaboutit's post. His V was in yesterday at the dealer for the PCM reflash. They literally accused HIM of doing something to his PCM to cause them to have trouble performing the recall. These guys at Colonial are literally Nazi's.

As for GM, they are supporting the dealer 100% and claim that the additive is NOT needed. I asked if I could please add it as I believe the rear is already grinding and groaning. They called back and claimed that if I added the friction modifier they would void my warranty. This is GM mind you. Today it's me, tomorrow it's the rest of us.

Again, please call Karen and let's force GM to come clean on this. How many differentials need to fail before they admit there's a problem!? We currently have 3 forum members V's in dealerships RIGHT NOW awaiting rear differentials that are on national backorder. YOOHOO, GM WE'RE ON TO YOU.

This is absurd. I mean, you surely can't be serious...

This person claims that the CTS-V doesn't have a limited slip differential? She's either an idiot or has the wrong car in mind.

I will definitely lob a call tomorrow. That is literally laughable.

The dealer that I have been dealing with (which has rumored to be a "non-Magna friendly" dealer, but been very much up to the "calling") informed me that an additive WAS needed (the computer was telling him this). This is the DEALER mind you. This was taking place as I was pulling out a printout from this website to show him what fluid and additive was needed. He reviewed my printout and said, "Yup--that's the one I see here...."

I'm VERY curious though--it's laughable how easy it is to literally PROVE her wrong (see the many "burn" pics on this site). What did she say after you mentioned that to her??

James at Lindsay called his Cadillac tech line people to verify that the diff required the additive after I sent him the getrag response..They verified that it does. Lindsay is #2 dealer on the planet! I doubt they would BS him. Getrag is the manufacturer, who would know better then the horse!
Certainly more than the horses ass.

Unbelieveable! GM told my local dealer that they had screwed up by not including the additive when they changed the differential fluid leading to extreme grinding and had them replace the rear differential under warranty. This is ridiculous. I think I recall a long ago post showing specifications requiring the additive.

CVP33 -

If I were you I'd find another dealer. They don't know what they're talking about. Here is the info my dealer gave me regarding lube specs for the diff.

We have little hope of getting the diffs fixed if they can't agree on the lube specs.

Document ID# 1387435

Differential Lubricant GL 75W90 GM P/N 12378261 (Canadian P/N 10953455) 1.37 qt

Limited Slip Differential Lubricant Additive GM P/N 1052358 (Canadian P/N 992694) 2.7 oz

WTF,this is sad.Writing number down to call.This pisses me off.Nobody is this f'n dumb!

You know what is most absurd about this is that even though the V most certianly has a limited slip diff, friction modifier will not harm an open diff. It is perfectly safe to use the additive in an open diff.

A dealer interested in customer satisfaction would just add it but saying it will void your warranty is just a lie.

Well, you bought a $50k car, if they won't fix it, then use your state's lemon law to MAKE them fix it. Either they fix it, or take it back and give you a new one

Might I direct you (and GM) to http://www.cadillacfaq.com/faq/doclib.html

Download the brochure.pdf and go to page 3, 2nd paragraph on the right

Next on list - vsales.pdf 2nd page, 5th paragraph with "Performance Power" in bold

Same document, page 5 - can't miss it. Again on pages 12 and 18 (listed as STANDARD FEATURE on 18)

Seems to me your dealer is implying flase advertising and GM is admitting to the same

And then there's this:

and this (under intermittent noise)

F'in dealers

Fine, don't add the friction modifier and then hire an attorney to document these actions. Your diff will last about 4-5K miles - trust me I know - and you'll have a hay-day at that point
