mdemello- Welcome aboard.
That said, sit back and read a bunch more posts before drawing any conclusions about how we feel about dealers.
First of all, in many cases it's not the mech that we're p. o. 'd at, it's the drones at the service desk that 'screen' a lot of these troubles and the service managers that refuse to treat us as valued customers. They're very quick to decide that they can't find a problem or to blame mods, or to play parts-changer at our expense; also not very well informed when it comes to what is and isn't covered by warranty.
In most cases where a dealer has been maligned it is due to the attitude (as A. Brown succinctly stated) we are given by the dealer service reps, the bad ones do not treat us as intelligent or knowledgeable about our vehicles, and in many cases treat us like children that they just aren't going to humor instead of treating us as valued customers.
If you read carefully you will see threads started with positive feedback on dealers that provide good customer service so that everyone in the area knows which dealer(s) to patronize.
The bad ones are detailed in full as to what the bad experience was so that others don't frequent those dealers if they agree that the treatment was shabby.
The biggest complaint we have about the mechs who work on these trucks is that many of them don't know squat about diesels and are playing diesel techs for the day. Those and the ones that either refuse or are not allowed by their mgmt to discuss their troubleshooting techniques/findings with us so we can try to come to an agreement on the trouble/diagnosis if we don't feel like our issue(s) were addressed.
It's nothing personal, mon!
