Purely HYPOTHETICAL situation here: You tow your truck into the dealer because it won't start and it's still under warranty. The dealer tells you you got bad fuel and the warranty won't cover it. You bring the truck to an independent mechanic because you don't want to pay the high dealership repair prices. In the end, it ends up being a bad injection pump and there was ABSOLUTELY NOTHING WRONG with the fuel. The dealer misdiagnosed a problem that was CLEARLY still under warranty. Should you have to "eat" the repair bill, or should the dealer pay?
Unfortunately, thats the rub. . Dodge uses the dealership network to buffer themselves from the consumer. Some warrantable issues are clear as mud as far as whats covered and what isn't. Some dealers know how to do warranty work and get paid for it, others don't, some dealers bill the customer AND Dodge for the same repair!!. Its NOT just Dodge, more and more companies are that way.
In your hypothetical situation you end up with your truck fixed, but you get the truck back along with the bill... . You're mad at Dodge, but you get the truck back.
You go to Dodge looking for some sort of admission that they didn't really handle the situation right and you would like to be re-imbursed for the parts cost and are willing to eat the labor... . only to have some idiot that didn't know what they were talking about to begin with look you straight in the eye and say... " Well Mr. Smith, this is a very unfortunate situation, IF you had allowed us to do the repair we would have found (once we were able to disassemble the fuel system) that it wasn't a fuel quality relate issue and we would have been able to repair the fuel system for you under factory warranty. But consiquently, we will not be able to reimburse you for this repar due to it not being performed by us. Please give us the opportunity to serve you in the future. " Everybody translates that differently, but when it was tried on me, I translated it as " this person is the person that tried to give me the shaft, and since I didn't allow them to rob me blind, now they aren't going to do their jobs!!
Now, with all that being said, if, in the hypothetical situation you offered, you had let the dealer do the work... . The dealer would have never LOOKED for the real cause of failure, and if they stumbled onto it, you would have STILL paid the entire bill. .
I have just decided that barring a catostrophic engine failure, my truck never had a warranty... Although I bought it brand new. That way I don't get angry and never have to look at the dealership again. .
