I think I've said it here before but I'll say it again anyway.
I belong to a few Motorcyclist Forums I've owned my fair share of "Problem brands" Namely BMW's and Moto-Guzzi's, We talked about these Ratings at one point and found that over-all A LOT of these surveys really hold no merit In my opinion,
It was being discussed on the BMW forums about how the Motorrad's constantly get lower rankings compared to Say the Japanese brands even coming in dead last sometimes (
It also doesn't help that BMW had a SLEW of Final Drive Failures between 05-11 that they were refusing to acknowledge and that reputation haunts them to this day, Same with Ram and their 6 Speed Transmission still haunting them Reputation wise), Someone on the forum dove into the Consumer reports and did some research, The problem they found was that some reports counted "Going back to the dealer for a Warranty Fix to replace a Light Bulb" the same as "My Engine blew a piston out the side" So of course the Bike' Brand's that offer more Electronic rider Comforts were getting hammered by the brands that offered just a basic bike.
As for Ram and their reliability, I have a Lifetime Warranty so I could care-less really, and I'm willing to give them a Chance, I'm willing to give ANY brand a chance if they catch my eye, That's kind of another thing I hate is when people cry and moan about a product being unreliable when they've been the Third or Fourth owner..
I do see your concern though it's just like those of us on the Motorcycle forums which were split into two camps which were either "I BOUGHT A 20k+ BIKE AND ITS LAST BLA BLA" or "Well it's Italian so what did you expect?"
My own personal spin is if the Truck can make it to 40K with no issues what so ever, I'm happy.. For some reason all my past Vehicles my Mustang included if there was Warranty issues that was gonna happen it was at 30K.. Like the Intake Manifold failure my Mustang had or the Turbo blowing out on my Tremor..
