The dodge 3.6 has a major issue where one of the internal oil galley plugs comes loose causing loss of oil pressure to the rocker arms. It presents itself as a ticking noise coming from the engine. You have to replace the rocker shafts, rocker arms, and if you let it get bad enogh, the camshafts.
Dodge fwd tranamisaions have been an issue for almost 40 years. People neglect them and put the wrong fluid in them, which makes them go bad.
Maybe it was that i had to install the snap version (or maybe flatpak?) and uninstall theirs, which fixed the crashes. I thought it was a hardware issue for awhile because it was so random.
