The dealer is correct, Chrysler says incompatible. So they are doing what Chrysler says.
In reality they can be installed. Many here have.
While the hands free door sensor can be re-installed with the running boards mounted they don't go in 100% the way it originally was, but they are still solid.
I believe Chrysler says no to hands free doors and running boards combo to limit their liability because of the two following points:
- to activate the doors with your foot with the running boards installed your foot needs to reach further under the running board than under the rockers alone. Possible perceived tripping hazard?
- the OEM rocker panels cover and protect the hands-free sensors from the elements. Water / snow / mud / etc. With the sensors fully exposed their lifespan may be reduced, or may be easier damaged by debris.
My dealer, after much persuasion, eventually agreed to install after I ok'd them disabling the hands free doors. They did so in Uconnect by turning off the feature and by not re-installing the sensors under the van.
I re-installed the sensors myself the following weekend. They still work (though more difficult), but we still don't use them :-) I mainly didn't want an exposed harness end open underneath the car.
Over the winter we did get a "door sensors are dirty, wash underneath car" error on the dash a few times. It disappeared quickly and when the winter gunk melted off it stayed away.
