Just to verify, on as in the light below the radio for FCW is NOT lit.

Re: WK2's Have Forward Collision Warning Issues

Correct, the light is off, if I press the FCW button, the light comes on and the EVIC system says FCW is unavailable... Thanks..

Re: WK2's Have Forward Collision Warning Issues

Mine works as I expect it to. I am not sure that it works as designed. I did think it was too sensitive and switched it to near... (alerts you for events occuring closer to you and therefore not as sensitive).

It only works when ADC is on, to the best of my knowledge.

As another point posted earlier on this thread, The type of fuel used should have no effect on how the transmission shifts. The ENGINE may run different but the TRANSMISSION has no way or reason to know what fuel burns in the engine. The manufacturer recommends regular unleaded. I was told by multiple mechanics, salesmen, and even chrysler themselves that anything more does not improve performance and just wastes money.

My 14' overland collision warning system has saved my butt 2 times now while driving in Southern California on I5 people just slow to a stop out of nowhere around here it scarred the hell out of me the first time though. I think I had ADC on one of the times other time it was off if I remember correctly I've tried to test it but this damn thing is hard to fool. As to fuel I use 89 octane that's what the book says to use no clue if it makes a difference have the V8 though i think the 6 says 87. Just took a 1000 mile road trip computer says I'm averaging 21.3 mpg set the cruise on 80 mph and sat back I'm impressed o most 500 miles to a tank of gas works for me.

That has been one of the best things about switching to the Jeep for us. I LOVE filling up with 87!! I haven't had a family car I could use regular in in years!!

Re: WK2's Have Forward Collision Warning Issues

careful, folks: Chrysler recommends 89 for the 5.7L, 87 for the 3.6L

Bottom line is, the system does not work or warn me under any circumstance UNLESS I am in adaptive cruise control mode, then it works. Techs at dealerships are incompetent and refuse to fix something if it does not trigger the common error when they run a systems test via a scanner.

There are many other people with the same issue. My point of view is jeep should give it a further look. But who am I to be quick in blaming them when the message board hippies dismiss so easily as well. Common minds think alike I suppose.

At any rate, I am taking the vehicle in this Saturday and will probably get the same diagnosis of 'well we scanned it and there are no errors so it must be just fine'. Well then, how exactly is it a 'FCW system' when you are going 70mph and someone fully slams on their brakes in front of you due to an 18 wheeler blowout and zero warnings go off whatsoever while you barely clip their bumper pulling into the emergency lane to avoid a collision? Does not sound like a working system to me.....

back at y'all non believers!
Someone in front of you at 70 slams on their brakes, and you are close enough that you clip their bumper?

At that speed you are relying on a warning system as opposed to your eyeballs?

On a serious note, I wonder if the unit is looking more for intrusions into your path from either side as opposed to something that is steadily in front of you suddenly shrinking the distance?

I'm trying to remember if mine has ever triggered in heavy stop, jerk, go traffic... it does trigger on someone changing lanes much further out than someone sudden stopping.

Re: WK2's Have Forward Collision Warning Issues

Nachojeep, when you mentioned ADC, are you referring to Adaptive Cruise Control? I was told by the dealer FCW do not require ACC to be enabled to work. As for my rough transmission shift in low speed, I made an appointment with the dealership to have it checked out tomorrow, it's just not acceptable on a new vehicle, way to uncomfortable of a ride in traffic, I'm wandering if my issues have anything to do with the 300KMs it had prior to me purchasing it, the dealer said they had to drive my jeep from a remote location to get it to their location.. Found out after the purchase that the manual said the first 500KM should be driven under 90KM Per/Hour, don't believe anyone will follow that recommendation for 300KM on the highway..

You are correct FCW and ACC are not directly related for operation.

Also, yes, your transmission may have learned something stupid. If the dealer does not give you a good answer there is a thread on the rough shifting transmission that is a DIY quick fix.
