My Jeep almost killed me today?

Long story short was driving with the family, and a car was turning right about 150 feet ahead of me and it activated my collision warning. Well the thing is the car was out of the road way, and I was still accelerating.

I drive with my hand on the gear shift knob, as I have for the past 15 years of driving a stick. It wasn't the near collision that almost killed me, it was the fact that it stood on the brakes at such a level of aggressiveness that it literally threw my body and arm forward enough that it pushed itself in to neutral.

The car behind me almost hit me at 55 mph. I'm not mad at the car, but it appears that I won't be resting my hand on the shift knob anymore.

Now you have me scared to use my acc. My wife doesn't like to use her seat belt and it could cause her to hit the dash or worse the windshield.

Many people disable the FCW braking for this reason.

Personally, I just stomp on the accelerator when the FCW/braking freaks out with these false alarms. It can only automatically apply 40% braking anyway. By design it automatically releases the brakes after two seconds or so... the better to allow you to hurtle to your death (heh).

ACC and FCW use the same sensors, but are different functions. Many people disable FCW and use ACC with no problems.

Re: My Jeep almost killed me today?

WOW!!!That was a lucky escape!Fortunately you and your family are blessed with no injuries,just,I am sure,shook up.
I think I recall a few threads noting many people are unhappy with the selector in later model JGC's
Like you,I have a dreadful habit of keeping my hand on the selector,(in my case I think it's years of driving stick shifts),I have to admit,I didn't like the set up of these selectors,but that's me,there has also been a lot of notes of people not realizing they were not in park when exiting their vehicles.
My wife uses the '15 and I stick with the '11 that has the older type selector.I warned her about these selectors so initially she was very careful to make sure she was in the gear she needed to be,now it seems like second nature to her.
In the end,fortunately your all ok!!Thats what matters most.

Re: My Jeep almost killed me today?

What year is your Grand Cherokee?

My 2014 Grand Cherokee has the notoriously unreliable first-generation FCW, which I still don't trust even after its firmware has been upgraded.

Re: My Jeep almost killed me today?

2015. Kind of a bummer that you don't have to push the brake to go to neutral. I can understand going from D to S. But to go upwards towards reverse the brake should have to have pressure to engage the switch. Unless it recognizes the FCW as braking and I basically had a fluke situation.

Either way, lesson learned.

Re: My Jeep almost killed me today?

I have the active braking disabled on mine. Not because of a bad experience, but because of the stories I have heard. It will still warn you on the dash as well as a loud audible tone if it detects a potential collision.
To turn active braking off just go into your uconnect settings and turn it off. its probably in the safety section.

I use ACC on a daily basis, no issues whatsoever.

Plus, if some doofus stops in front of you, you need that extra velocity to "larn them sumpin".

Re: My Jeep almost killed me today?

Not too many people die in a rear end hit when there is nothing in front of them. Soft tissue and whiplash, maybe, if seat and shoulder belts aren't adjusted properly.


Mostly a change of underwear gets people on their way.

Re: My Jeep almost killed me today?

Although I have the FCW activated, I'm not using its automated breaking. The reason is that such a system is not perfect - like when you are approaching vehicles that are on a turn lane right next to you either left or right.

Sometimes, the system thinks they are on your lane and you are approaching them too fast. Well, while the latter is true, the former isn't. While I don't mind getting the warning, I certainly don't want to have my Jeep brake for me in that scenario.

This happened to me 5 minutes after taking delivery which was a bit scary and I disabled it ASAP.
