Forward collision warning (FCW) and automatic emergency breaking (AEB) malfunction??

Definitely an issue. My new 2019 wrangler unlimited screeched to a stop on the lower level of the George Washington Bridge with no one in front of me a month ago. It was super frightening and am glad I wasnāt rear ended. I took it to my dealer and they ran thorough testing for 3 days And found nothing. I didnāt realize it was low ceilings and side barriers causing it until it happened again on the FDR drive in NYC when I went into a low ceiling underpass. I have disabled the auto breaking and now I just get the warning which is fine.

2019 JLUR here. I've had all of these issues happen, and one worse.
I've had the Rubi stop on the lower level of the George Washington from a small stream of water coming from the upper level. Luckily, no traffic behind me and I reduced the sensitivity. Later that same day, Rubi thought the column of an overhead pass was stopped traffic and it engaged the auto stop until I aimed the jeep into the other lane, and it let go. I turned OFF the active braking system. Two weeks ago while raining, system was Beeping & dash said BRAKE, but brakes did not engage. I pulled over and restarted the Rubi and it was fine. Last week, going through the lower level of the Verrazano Bridge during rush hour traffic, Rubi did full stop WITH THE SYSTEM OFF as it thought tiny dripping of water from upper level was an obstacle. SUV behind me stopped in time, albeit, sideways. I called Jeep Care immediately afterwards to let them know that if they find me dead in the Rubi from being rear-ended to look at that system. They said that they did not see any recalls on my vehicle, but to take it to the dealer to pull codes. I went yesterday. Dealer reviewed codes. No issues found. They then found the software update noted above and they updated the PCM, EPS and the DASM.
I'll let you know if the updates worked, but if you haven't gotten them done, go. Remember, my system was turned off and it saved the life of that water drip, but nearly killed me and the driver behind me.

I am thrilled to see that there is an update for this. I started this thread after a couple incidents in my parking deck at work, and believe this is a totally dangerous flaw in the FCW system. I canāt wait to get in to the dealer and have the update applied. To be honest, I canāt believe this is just an āupdateā, and not an actual recall. Thanks for the info everyone!

Mine slammed on ther brakes at 20mph on ther highway with moving traffic. Looking at my dash cam afterwards there was only a car to the right that could have triggered it.. Turned active braking off and prob won't re-engage.
I'll get ther flash update when it's in the shop for inspection or something else. Certainly not as good as my Subaru but I do love ther adaptive cruise control!

I wouldnāt get too excited.
āmy Jeep was built AFTER the date on the TSB so.... my software is correct. BUT, I had the same issue that you experienced ā- also in a parking deck. I want nothing to do with a beta test bit of software. See my post #45 above. I turned the beta software off.

Already did ;-) Driving under bridges almost all the time. (Working in Portland,Or.....with more than one metal bridge there...)
Again, best safety feature ever.Today with rain, was just awesome.
Have a great night.
