So on Monday (the 7th day) I decided to give them the "ultimatum" -- you know, "fix it or else..." I left a voice mail with the service writer that I wanted a guarantee the truck would be ready by the end of the day or I wanted the name of the General Manager. The Service Manager called back within a half hour and was all apologetic. He said it was on the rack and they were working on it. Huh, it was on the rack on Thursday -- guess they have lots of extra, unused racks!! I asked why it was day 7 and the 6 hour job wasn't finished - especially since I had an appointment. He said "I had no idea your truck was here for 7 days." Before nearly passing out from the stupidity of the comment he added that it was the shop foreman's fault for not letting him know they were overloaded with work and now that he is aware of the problem he is putting two people on it, but can't guarantee it will be done before the end of the day, also, that it is "shop policy" to give priority to jobs that were returns for failure to fix. At this point I can hardly contain myself. First, I MADE an appointment; second, they called the day before to remind me that I needed to be there by 8am for my appointment -- so there is no excuse of being "overloaded"; third, the service manage only knows what is going on if someone tells him (actually in my working life I knew some managers like that) but really, how pathetic is that; forth, so if it is shop policy (which I assume everyone would know it) why did my truck sit until day 7, why did the service writer say that only one person worked on warranty jobs like mine, etc. etc. Anyway, while I wanted someone's head on a chopping block, I decided that it was in my best interest to get the truck fixed so I, ever so politely, said thank you for taking an interest in fixing my truck that you have had for a week - that got me another insincere apology. I got the truck back by the end of that day! I have now driven it for a week and pulled a trailer over the sierra's and back and there is no leak!! Hooray.
Oops, perhaps my exuberance overflows, but it is nice to think this is now behind me.
Thanks to everyone who contributed words of encouragement.
