Ford's remote start has a 15 minute cutoff without any intervention. Using numbers from a cold-started 2011 F-150 Raptor during a driving test and trapping it in a single car garage, 15 minutes with zero circulation results in ~40-120ppm carbon monoxide* which would still take multiple hours of exposure before symptoms occur. Your bronco probably has lower emissions and with good circulation to the much larger air volume of the rest of the house CO poisoning really shouldn't be a concern. Obviously don't use the feature with the door closed but accidentally triggering it wouldn't be that big of a deal. It also is pretty hard to accidentally trigger from the fob, requiring pressing the lock button and the remote start button twice in quick succession.

* 0.263-0.725g CO/min in a 12x22x10 ft garage. higher number is from testing under load before the cat is warmed up
