If you can, I think it will depend on options at best. I suspect the crash avoidance stuff is not compatible with the trailhawk front end and rear end and thus why it is not available as an option for it. No place to mount the sensors.
The other thing I would be concerned about is it mating up with the wheel well liners, which are part of the sound dampening strategy. It might have adverse effects on cabin noise and keeping things dry.
I looked at several pictures of the Latitude and Trailhawk front bumpers on the Jeep web site as well as other web sites. On the right side (US version passenger side) of both bumpers, there is a round cap or plug or something. That could be a sensor behind it. Both bumpers meet the wheel well the same. They also meet the valence between the bumper and grill the same and the openings for air flow at the top of both bumpers are the same. Sensors may be located in that area. The lower part of the bumper on the Latitude looks somewhat like a lip. It’s not smooth to go over rocks and brush the the Trailhawk bumper.
I think the reason for the Trailhawk not having the crash avoidance is because they (FCA) has not perfected it for off road vehicles. When air bags first came out on pickups, off road pickups did not offer air bags because the system had not yet been perfected for off road use. Of course now a day, they all have air bags. I think it’s the same for the crash avoidance systems.
After the Renegade hits the show room floors in the US and the parts departments and service departments are able to get a better handle on actually knowing what, where, and why of the bumpers and crash avoidance system, then we’ll know if it can be done. I would be surprised if the inner wheel well liner was different between the trim levels. They need to keep as many common parts between trim levels as possible to help keep production costs down.
