Super weird. I've changed the blades on my 2013 a couple times. I think 1st was Trico Blades from Rock Auto, and then Michelin Blades from Costco. No issues both times.
Last year I starting running 4x rear rims all around on my 451 with 175's front and 195 rears. HUGE improvement on ride and handling. This year I will be running 195's on all 4 corners in the summer and 175's all around for next winter. Easier to find tires in those sizes too!
I had the exact same issue with my 2013 nav radio, it started off randomly and sporadic. Then was more consistent. I ended up putting an aftermarket radio in it.
Yes I have one out, on my bench ready to go. (the one I texted you pictures of the other night) It would cost about $20.00 to ship it through Canada Post. + the cost of the part.
Honestly, if I were you I'd get the new one from the place Izzy mentioned above. $78.00 is pretty cheap.
I have an '05 parts car at my house right now. I'll look tonight to see if that hose is there. I work with Izzy, if I don't have it, he will. I'll text you later tonight.

For pricing from a dealer, that doesn't sound too bad. (yes it should be cheaper)
An example of outrageous, is Paccar wants $10.00 for 1 single high temp ZIPTIE. It is blue, so maybe your paying for the color? haha
