Unfortunately, that doesn't prove that the system doesn't work as it was designed. It just proves that it doesn't work the way you expect it to. We don't really know what the design parameters are for the system to engage. I think what this does show, is that there is a problem in the industry which leaves safety parameters up to manufacturers rather than the consumer.
Mine is set to far from day 1 and still doesn't work as advertised.
Thanks for this update! Do you have a pic of all the work your dealer did? Specifically looking to see what computer updates was done.
They just did the software update that everyone was talking about. As to the hitch, they installed an aftermarket one (Curt brand) because the Jeep hitches are back ordered till late may. Looks fine, fits behind the bumper. There was no wiring behind the bumper and they told me >$1k for the wiring. I’m going to dyi an aftermarket 4 pole wiring harness from etrailer for a little over $100 (splices into tail light wires).
I bought my GCL on December 23, 2021 and it has never worked. Several weeks ago I was on the freeway driving at 80 mph and the guy in front of me did a hard brake and my system didn't warn/detect anything and the brakes were activated. If I had been distracted, I would have crashed into the guy. I have taken the car into the dealership twice, did a test drive with the service advisor and he agreed the system doesn't work but after they kept the car for about 3 days they told me they ran a diagnostic and checked it with Jeep engineering and the system was operating "as designed". I gave up.
Don't hate me for saying the obvious... but did you use the right cruise control button? There are two, one is the Adaptive Cruise Control (ACC) and the other regular old Cruise Control.
I think Forward collision & braking should work with both cruise controls.
It doesn't with mine. Forward only would be good though.
Yes I understand that, but what I mean is it should brake on its own in case of emergency regardless of any cruise setting and if cruise is off too.
No worries. I was not using cruise control. I had to brake because all the lanes on the freeway had traffic so my only option was to brake hard or crash. I chose to brake and drove away without a scratch. I was just upset that the Forward Collision system in the car did not work. No alerts, no braking, nothing but according to Jeep "the system is operating as designed".
Agreed, Hamada. The system should brake the car on it's own regardless of the cruise setting or if the cruise control is off. I did a test of the system to see if the car would brake on it's own when the Adaptive CC is on and it does brake the car. It's a little aggressive in the way it brakes but at least it stops the car so I know that system works.
You would think if your ACC cruise works all the time, this would as well, at least as far as the sensor goes. In my experience with other systems on my car, though, electrical/software problems happen completely at random, and often leave no trace as far as error codes are concerned. I've had my FCW error light come on quite a few times, but it seems to he better with the latest software release.
