    Default Duramax Diesel GM

    My friend who's a parts manager for GM has notified me that GM now has software that will detect if in fact you have uploaded any programs such as Hypertech, Jet programmers. If so you automatically void your warranty, when you blow up your engine don't have it towed to the dealer for service. Now I'm out $500.00 for the programmer.

    this topic of dealers voiding waranties if you put tuners on your truck has come up time after time over the years. According to the manufacturers of the tuners, ie... edge, bully dog, ect..., it is against the federal law for them to void your warranty for adding bolt on parts. As far as I know, nobody has ever taken this all the way to court to fight it. They simply move to a different dealership and drive on. My F350 has been to the shop as has several of my friends with thier trucks, Chevy, Dodge and Ford alike with the tuners sitting in plain sight. It hasn't affected our warranty one bit. They even replaced the turbo on my buddy's truck. Before you write off your programer, call the programer manufacturer and ask them about this alleged new policy from GM. just my $.02

    That sounds real logical, but when they know that the program has been installed and then taken out, what's your defense? I just heard it from the horses mouth, I'm not going to take that chance! I would like to drive up to my local dealer rather than driving all around town trying to find someone that will cover the warranty.

    The dealiership I bought mine at has no problem with mods. As long as people are up front with the service writer and tell them what they have done, there should be no problem. They want the business, anyway. They have to make money and warranty pays them. So, unless there is obvious hardcore situations, like Nitrous WITH Propane AND a tuner -sure they are gonna have to point a finger. To just mod the exh, intake and do a moderate tune, hell peeps have been doing that for years and not had a problem.

    Larger wheels/tires, lift kits, lowering kits, stereo changes - all are things that can void your warranty. As it's written - ANYTHING other than stock configuration is voidable. All of my trucks - and my wife's stuff has been dropped, bagged, wheels, tuner(s), exh, intake and I have never had one dealership even look twice.

    My last dually had HEADERS on it. The 7.4 Vortec sprung a coolant leak where the intake bolts to the head. When they changed it, they dropped a bolt down an intake tract and broke a piston. So, they put a piston in #6. They even had to wait a day because they had to order the correct header gaskets. Technically, they didn't HAVE to do that because it was not a GM piece.

    Hey, they are just normal guys doing their job. They are gearheads just like most of us are, and just want to do their job and get paid. Do you really think they care about a tuner and exhaust? I say, only if there is obvious neglect or misuse.

    as i am a gm diesel tech i know a lil about this topic. there is a way that we (as techs) can tell if an aftermarket programmer has been installed. only on 05's and newer trucks though. it does not matter if the programmer was installed and then you take it out to go get the warranty work done. it still shows there was a programmer installed at one point in time. most techs dont look for that unless there is a huge problem that doesnt usually ever happen unless there is a programmer, i know i dont. it takes to much time to do. a lot of techs are doing it now because it is our job on the line if the dvm comes out to inspect the vehicle that now needs a motor and finds that there was a programmer. then i could loose my job. most techs dont want to loose there job because they want to help the guy with the programmer out. as far as voiding the warranty. im sure they can, i bet if you look into the warranty itself that it will say that programmers will void it. once it has been determined that there is a programmer, gm voids the warranty and any dealership you take it to for warranty work will see that it is voided when they run the gm vis on the vehicle. it sucks if your the guy with the programmer. but come on, seriously do you really need it. they have a lot of power stock, unless you have the first geneation d-max 01-04 witch we cant tell if there is a programmer anyway. well if you have any questions just ask
