Yup: Last year they forced an update onto the radio/brain on my 18 Rammer. Froze the radio and couldn't access the heater controls etc. FCA? had to replace the radio and I had to wait 2 or 3 months to get it with no radio, no heater, no backup camera etc. Modern tech is lovely, I imagine if it happens again in a couple years that I'll be stuck with a vehicle with no defroster, heater etc. and it willl be tuff titty. the vehicle will be unsafe to drive in the winter.
I just finished putting on a set of headers too. Another known issue is cracked exhaust manifolds on the 5.7 Rammers, FCA/whoever has known about that issue for more than 10 years as well. Then there's the cam and lifter issue.
I've said it many times, the old Chrysler Corp is long gone, the Europeon car makers put out junk and don't care. It's a shame because my Rammer is an awfully nice truck and I'd keep buying them if they had proper support, but as it is no way.
