The 190's are prone to ignition switch failure, actually its the tumbler. Usually they give some warning. If they are replaced before failure such that the switch won't turn its a $70 part with minimul labor. If its after it fails and it won't turn (and unlock itself) its ten times that in labor to get it out

Don't know about a "park" switch, I have a standard trans. The car may be warning you its after your wallet.
