Chevy And Gmc Service Interchangable?

jthelman · March 12, 2009

I have a 2008 Sierra. I'm currently taking it to the GMC dealer I bought it from, and probably will go there until 20K or so miles.

There's a much more convenient Chevy dealer close for me, I can drop the car off and take the train to work.

Yes, it's the same company, but is the Chevy dealer going to treat the GMC as a "second class" because it's not a Silverado? I'm also assuming Chevy gets the same TSBs as GMC and can perform them right?

Then again after a chapter 11, who knows what divisions will exists, or how many dealers will survive

For warranty related work take your truck to your GMC dealer. I've heard that the different divisions don't do the warranty work for other divisions due to the complexities of how they get paid for warranty work.

They are interchangeable in the sense that a GMC dealership can work on a Chevrolet and vice versa so long as they have the equipment to work on the vehicle and have permission to work on the vehicle from GM. It has something to do with the warranty payouts and codes; even though most of the parts are the same or similar on the Silverado/Sierra, they do carry different part numbers. I believe that the DVM (District Vehicle Manager) would have to get involved. This was the process that I followed with the DVM field office until I left the company...

I would use the more convenient dealer. Especially for service.

Argghhhh. This was *exactly* what I was afraid of. They are the same GD company, so why all the red tape? Why have a separate set of part #s, when the vast majority of the parts are the same?

Sorry for the rant, it's just a shame that my truck is nice, but the company is so f*cked.

Thank you for the first hand experience.

Hey man, I know how you feel. I would call on Rich (MS3DALE) to verify if that is still the same procedure or if that procedure/policy has changed...

A good friend of mine owns a large Chevy store. I've bought many Chevrolet vehicles there and have a great relationship there. They won't do any warranty work on my GMC (thankfully it never has needed any) because they say GM will not pay them for working on another make. As far as getting paid goes, it may as well be a Ford. General customer pay type service or maintenance work is welcomed and they do great work.

Other areas or dealers may vary on this.

I work at a dealer here in maryland and have worked at about 10 other dealers as well in the state, along with some as accounts i have set up. GMC/Chevy dont have differnt part numbers the part numbers only change when the part is physicly differnt and or if there has been a supplier change,number change...ect. GM part numbers have nothing to do with the part they are essentualy numbers being assigned to a part. Over time people like me and im sure Rich can chime in here as well since he's been doing this for a long time, have remembered some of these numbers just out of repetition of work.

GMC/CHevy will change numbers due to differances like grille,fenders, light ect. but other than that everything else is the same. Now some numbers will be differnt if they are primarily for differnt cars ...like Hummer brand alot of numbers start with a 25, but again this holds no exact science. And some SAAB numbers start with 93's,and 12's but you only notice this from just quincidence.

Either way , Most GM dealers will only handle cross brand warranties if they happen to be Fleet,Employee, or you live to far away from your closest brand dealer. Cadillac for example wants everything to be seperate, they want there own showroom, seprate waiting area, upscale parts showroom...ect to reflect the Cadillac (premium) brand. You will only find a few dealers that have cadillac on the same style showroom as a chevy or GMC...cuz they just dont go.

Even better first hand experience

and or here is also a good example....hopefully this isnt too big. But if you look in the colum marked "usage" you can see the brand varances x88 (chevy) z88(gmc) z75 (caddy) ..but other than that same number might work for both unless specified.

this is just a part of the catalog, for gm parts. As some catalogs are differnt im using the Snap on version...were others will have bell and howell or something else
