The one that got me recently was back in March for my old Ram 1500 my son drives. The thing would not go into 4WD to for anything. My neighbor that's a mechanic worked off and on with it for two weeks, and then the Dodge dealership had it another two weeks. The neighbor was getting a message saying a wire was shorting out, but never could figure out which wire. Dodge had to call in an engineer, ended up it was the wiring harness going to the transfer case was corroded really bad. The wires were pretty much just dust. I thought I was going to have to sale a kidney to afford it, and when they told me my final bill was $731 I almost hugged the guy.
