Update:
After the last go-round, I called my selling dealer's sales manager and contrary to what RAM Cares told me, they could not find any voucher under my truck's VIN and told RAM Cares that.
Now today RAM Cares ignores that and tells me again to contact my dealer, that they should have the info under my VIN.
What has changed is RAM Cares has stopped using the term voucher, and is now saying it's a "Discount Code".
Bottom line, I'll be buying the step myself from a wholesale parts dealer.
RAM Cares may be doing something useful for other problems people have, but I doubt it. They done nothing but give lip service here on the forum.
I love my truck, and it's been almost perfect. I have minimal issues with the product to date, but i gotta say my first experience with RAM customer care has sucked. I've used the same GM dealer for 25 years, and one of the reasons for that is they have ALWAYS taken care of me and every other customer. Had this situation happened with a GM truck, my dealership would have put the step on out of their pocket as soon as they had one on hand. It's a no-brainer. There was a very small window that this was an issue, so their cost exposure is minimal, especially when you consider that they're getting the parts at cost.
