Chrysler Pacifica reliability?

My sister had a 2018 or 2019 (I forgot the year) and worked flawlessly until during covid lockdowns when microchips were in short supply and it had a check engine light pop up so they took it to the dealer for a warranty check and it turned out to be for the TCU. The van sat at the dealer for about 7 months waiting for the part to come in and when she got it back she sold it immediately. Had maybe 30k miles on it
