I voted that it did not pay off because the only time I had reason to use it, this happened (hope you got a few minutes. This is gonna be a long one):
I had a 2007.5 2500 QC LWB 4X4 with the 6.7L Cummins. When I bought it in October of 2010, the bank made it sound like they required the extended warranty for them to finance the truck, so I got it.. (I know, I know, but I was only 26 when I bought it.) I was about to leave work (Lowe's at the time) when I noticed the truck wasn't wanting to turn where I wanted it to. I looked up front and then two wheels were pointing different directions. Ruh roh. Took it to my mechanic, and the tie rod end had snapped on the passenger side. Thank God it did it in the parking lot and not on the interstate. Come to find out the extended warranty didn't cover steering components.
Next time, same truck, I had an injector fail. Took it in to my mechanic again, and he calls me back the next day saying he argued with the warranty company, but they refused to cover injectors, because my warranty didn't cover fuel delivery, either. He basically told me that the junk warranty they forced on me covered really nothing more than the block.
So there it is. I do currently have a full life-of-the-note warranty on my wife's Jeep, and I have an extended warranty on my current 2017 2500 6.7L, but it read through and made sure it covered that expensive stuff. I can see it being worth it, but I voted the way I did because the two times I need it, it didn't pay out a dime.
