Engine shuts off suddenly in the middle of road; several times on the way back home while my wife was driving with no warnings. Very unsafe if another car is behind. She cranked over and it went, but it happend again in an intersection after a stop sign, fortunately no cars were coming. No shows WARNING LAMPS, check engine light on or diagnostic trouble codes, but engine next day started making noises like knocking or ticking. Car is only 140k miles.
