FCW+Brake saved me today

I was going to work doing 70 on highway, and before I can even notice sudden braking in my lane ahead of me (I was maintaining 1/6 mile or so distance) The audio went on mute, BRAKE! appeared on DIC and heard a loud grinding noise while the jeep braked. Then, it let it go for about half a second and heard the brake grind noise again. I was about 10 inches or so from the car in front of me when it stopped. It shook me good, but I was impressed how it handled. While it was happening I was more focusing on the car coming behind me and just managed to brake in time too.

This experience is different than my 2015 Accord, which has Forward Collision warning only and it used to go 3-4 times a week on the same route, usually when i am speeding /getting close or some cut me off... and this never happened with GC, so much so, I was pretty sure that this Jeeps system is broken and was planning on getting it checked next time at the dealer. Now I am believer and this one incident paid for the Advanced Technology Package.

Just thought of sharing it with someone on the edge for buying the Jeep with this package. Though, the radar sits pretty low on front bumper and no way can
handle off-road.

Re: FCW+Brake saved me today

It also costs a lot to have it aligned. After I was rear ended last year I kept getting odd messages popping up saying acc/fcw limited then it would vanish. This was happening more and more so I took it to the dealer thinking it might be something under warranty. Nope , they said it was out of alignment and wanted 450 parts and labour to realign it. So I called FAC and got them involved and they said same thing as it was from a collision it was not warranty and to talk to my insurance about it. So insurance covered the cost of getting it realigned , no more messages pop up , and they also fixed my rear view mirror that was always falling off the part that glues to the windshield.Very annoying while driving to have the mirror pop off and swing inches from your face.

Good to know. Somwhat similar experience - My Audi A6 had adaptive HID headlamps and after fender bender, it won't focus. Geico shop had to make an appointment with Audi certified technician from Audi dealership to come with special tools to align it.

Re: FCW+Brake saved me today

A Jeep with FCW/ACC can absolutely handle off road.

The radar sits up in the front bumper. How can it not handle off roading? That's basically saying the whole front bumper can't lol

Glad FCW saved you. It's saved me before too. I like it

Good luck driving through sand and water or rocks. Where the bumper might just get dirty or scratched, it is bound to damage your FCW system.

How much and what terrain did you off road?

I didn't buy the Grand Cherokee to tear the shit out of the front bumper. I have 2 JKs for that. Typically in Moab on slick rock or somewhere in CO on sharp rock.

+1, Also very fond of the radar cruise control. Takes a lot of the stress out of rush hour traffic on the commute. I would be hard pressed to buy a car in the future without these two features.

The sensor sits at least 4-6 inches above the bottom of the bumper (on a Summit, at least). If you're hitting or damaging your FCW sensor off road, you are completely destroying the entire lower part of your bumper, and you're doing it wrong!!! Obviously it can't do the same serious trails as a lifted JK, but every 4X4 GC is quite capable off road, and an FCW/ACC system does not make that capability go away.

The FCW/ACC equipped WK2s are just as capable of Off Road use as the non-equipped ones.

And if you really want to go all out, there are instructions in the manual on how to remove the radar ball for serious offroading and the re-install it again. I kind of doubt anyone has went to that extent, but kind of cool that they give you the instructions to do it.... (pg 495 in the 2016 manual)
