Got the truck back. Turns out it was a leak from the filter assembly this time. And they snuck it under my sister's old warranty, like they did last time. Which means I only had to pay for a replacement key. (I've only had one key since about a month after get the truck. My mom lost the other set.)
Now I was supposed to get a call this morning on what exactly went wrong this time, and while I was waiting for that call, another call came it. I pick it up, thinking it was the auto shop.
"Hi! Your telephone number has been randomly sel~." Punch end, hang up. Then I turn to the other cashier, and say "Damned viaducts. They seem to come out of nowhere, and always cause a cell phone to cut out... especially when you get a fucking telemarketer. How odd."
And dammit, do I have to re-submit my damned cell number to the do not call list AGAIN? >_
