Of course they are the worst. I had quite a few issues with my 2005 Ram 3500 and my 2011 Ram 3500..... and compare it to my wife's 2007 Toyota Camry Hybrid that is still using factory brakes and batteries, the only non-maintence item in 140K miles on the Camry was a water-pump at about 96K.
My 2016 Ram 3500 i picked up three weeks ago is already not reading the tire pressure so i get a warning for Tire Pressure service now.
Compared to my 2005 Ford Excursion 6.0 Powerstroke the Ram trucks are great. Compared to a Toyota Car they suck.
