"throwing money at people for doing nothing", IMO, sounds like it. Perhaps you didn't mean to say it that way and I am, as a retired tech, by no means "thin skinned" and "looking for a safe room". It was a statement made in the heat of the moment. You have spent money and gotten nowhere YET. A tech's time has to be paid for, for good or bad, except blatant dishonesty. The techs are doing "something", it's the fault of the truck for not failing long enough to be traced and problem found.Would never bad mouth a tech. I am very thorough and clear when speaking with them. The level of frustration is high for me in this matter. I keep notes on what I say and results of what happens as a result.
I'm here to get input and so far I've been getting a lot of great information from people who have nothing to gain from helping. Which I hold in the highest regard.
Thank you for your input it's valued amd duly noted
I know you did not mean it, just be aware that besides myself, there are likely techs on here that would feel as bad as I would if I could not duplicate the problem or find the problem. In those instances, I usually apologize and cut my diagnostic time/charges in half.
By the way, did the dealer tech check for TSB's about this problem? They should have. Even if they tell you they did and still found none. Did they mention TSB's?
