Try just replacing trim first. I has having same problem from get go with my GCO only to discover trim was never installed on vehicle. Dealership still charged me the $21 for the trim, wasn't worth my time to argue over $21. BUT no problems with FCC/ACC since trim was installed.

I wonder why Jeep put our ACC sensors in such a vulnerable spot? My MDX had the sensor in the grill behind a clear piece of plastic. It seems like that is a better solution when it comes to dealing with road debris...plus it is going to make it very difficult for me to install my prerunner :-(

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.

I totally agree with you on the aesthetics, and I am sure that was thier reasoning. While I understand and accept that most JGC's will never see dirt and alot of the ones that do will only do so on well traveled/maintained dirt roads, I still thing this was an egregious oversight. Especially for a company who touts it's go anywhere attitude. Don't get me wrong, I LOVE my Jeep but I just wish they had come up with a better place for the ACC. As far as the aftermarket parts, i am sure they could care less about that stuff and rightfully so. There is no way they can accommodate any and all aftermarket parts or ideas. I am just going to have to figure out a way to remount the ACC on my prerunner so it is in the same exact location as it was from the factory, make sure it has a clear line of sight and keep it well protected...piece of cake. ;-)

I don't have enough info on the MDX to compare but on the Jeeps and similar FCA systems, there needs to be an angle distance variance between the camera and proximity sensor on the bumper. I suppose it could be higher but the masking in the system would not be nearly as affective if it was further off the ground.

Think headlights, the higher they are, the tougher it is to get good distance down the road without lighting to high in the vision area.

It is a performance balance. The closer that sensor is to the road the better it works as you drive over different grades.

That makes sense. And that does make me feel a little bit better about thier choice to put it there.

the ARB bullbar moves the sensor to a higher location, seems to work fine for people with that setup.

Wow $1850, the trim ring is just plastic with minimal cost and fairly easy install on the sensor so that sensor part sure has a heavy price tag.

Would it be possible to cover the area with perspex like a headlight protector type setup?

Sorry it took so long to reply, I was away on vacation. The first picture is what it is supposed to look like. The second picture shows the missing piece on my truck. I brought it to the service department today and they have to order the part. They "strongly feel" the missing cover is causing all of the error messages. I'll post the results when the part comes in.

I don't know why I didnt think to check this sooner. When I first purchased the car, I thought that was a strange way to finish off the sensor, but never compared it with what it should look like.

Crazy that I took the car in complaining about my radar, they checked it out, OK'd it, and gave it back all the while missing that cover.

Here is what mine looks like:

I will send an email to my service advisor. I am taking the vehicle back in next Monday, and I would hate to bring it in and then have to wait AGAIN for the part to be in stock. Hopefully they can order it now.

I installed a trans cooler and i prob bumped the fcw sersor so i got the fcw not working warning. I went to clean it and i noticed it wobbled. I removed the bumper facia and noticed that the sensor is held in place by 3 adjustable screws mouned in wimpy sockets. My fcw sensor could be popped in/out of the sockets. I removed the wiring harness plug and installed a 4th screw (10-32 x 2"). It screwed right into the 4th empty hole with the plastic insert. I then doubled nutted it. I drilled another hole for the harness plug. I took pics but i dont know how to upload them.
