No, its not. All three of the HD truck manufacturers are having supplier problems...but Ram seems to be the worse.
I own two HD Rams so I'm on the Ram forums all the times and lately the number of complaints with the newest Rams have grown exponentially. For one, after many many years of having Cummins engines built with solid lifters for some silly reason they are now made with hydraulic lifters and these new engines seem to be having teething problems. And the problems with electronics are myriad. The latest - apparently there is some kind of sensor on the rear axle that goes bad. When it goes out the transmission will refuse to go into Park position. And if the transmission can't go into Park, the engine cannot be shut off. Owners are having to pull the battery cables off the batteries to shut the trucks down. And they are being told that those sensors are on backorder - with a 4 month leadtime!
Reading about all the problems makes me so happy I own older Rams. They've been essentially trouble free.
