Maybe whatever caused the shroud to come off also damaged the sensor?

bsc', unfortunately, anything located in that particular area is susceptible to physical damage from road debris, etc., whether it's electronic in nature or just visual trim. It's always been that way on vehicles and always will be that way. The fact that a trim part is actually missing and evidence of physical damage to the sensor is evident unfortunately isn't a design issue. "Something" caused that damage and it's unlikely that Chrysler or any other manufacturer would take responsibility for that under warranty. There is likely a specific exclusion for that in the warranty language, too.

I suspect this was platform related...remember, this platform version of the Grand Cherokee was co-developed with the ML. While in "real life" this turns out to be a spot that's somewhat vulnerable to road hazards, aesthetically, it works well and doesn't interrupt the Jeep grill design higher up. As to interfering with aftermarket products like the prerunner...well...that's marketing related. The vast majority of the JGCs produced (1200 per day) never leave the road, especially the upper trim levels where electronic features like this are either standard or a popular option. Jeep's design is to support the larger market as it exists.
