Notes by brand
U0404 is a familiar code on Grand Cherokees and Commanders with the console electronic shift module, and on later Grand Cherokees with the spring-return monostable lever, where drivers see 'Shift to Park' or can't get out of Park. Battery condition and a shifter software update are checked before replacing the shifter.
