Active braking or forward collision warning.....warning.

[Grit_dog]

Seems appropriate here. Had an interesting experience with our new Charger yesterday with FCW and active braking.
In short, the car totally mis read a traffic situation and the 6 piston brembos stopped the car dead in its tracks...way quicker than the car behind us could have stopped. Luckily the driver behind us had given adequate (too much actually for city traffic) room in front of him, or that collision avoidance system would have 100% caused a collision.
Word of caution for anyone with newer vehicles with this system.

That was a bit unnerving but I like the system and I'm glad it is so equipped.
On a similar note, the next truck I buy will have adaptive CC as well. If Ram doesn't have it I will buy the Ford.

You should never use CC in rain or slippery conditions. Hydroplaning or any loss of traction can cause the CC to react and cause a loss of control. There are warnings in your owners manual.

Great. I'll nominate you for internet Mommy of the year.

Apparently you still need one. You do exactly what the manual advises you against and then complain that it put you in a dangerous situation :S Didn't your momma teach you anything?

I didn't complain about anything. You seem to be the only one in this thread whining.

This I agree with, sounds like he was driving responsibly, and yet he is talked down about it, I don’t understand the point in that.

I don’t think he was really talking down about that driver. Think about how you drive. Light turns green and everyone starts going at a decent pace. All the sudden the car in front does a panic stop. That is a pretty though scenario. I am always looking a few cars ahead to avoid this type of stuff but in this case there is zero warning aside from the brake lights.

I have a friend who drive a semi for a large company. He tells me that he and his coworkers are less than thrilled with the system on their new trucks that warns them when they begin to wander in their lane, and lets them know when their following distance is too short.

About three weeks ago my daughter was creamed from behind while stpopped on the road waiting for an oncoming truck before making a left-hand turn. Luckily the truck just passed and she had begun moving when she was struck at full speed from behind. Witnesses say the SUV that struck her car never even started to slow down. Too bad that SUV didn't have the fcw system.

Same happened to me 25 years ago. Drunk driver. These days they are prolly texting.

There are people out there that shouldn't be driving. But they claim a "right" to do so. Maybe these new technologies will help. Certainly seat belts, airbags, traction control and ABS have helped, although you still hear people complaining about them.

And yes, I hope your daughter is ok.

Likely was texting involved. It was three girls in the SUV. The road was straight the sun was behind them, visibility was clear, yet the girls' story is that my daughter's car "just came out of nowhere". I don't know what charges were laid. Thanks for your expression of concern. I should have stated that, although both vehicles were destroyed, no one was seriously injured. Mandatory seat belt laws and air bags played a role. Had the accident happened a second earlier my daughter's car would have been launched into a head on with the truck.

So does FCA still work when a trailer is attached?
Wouldn't mind a Warning but hitting the brakes might not work out well.

My Challenger only hits the brakes when the adaptive cruise is on. If not then it just advises "BRAKE!!!".

If I recall, you have a newer than 2015 SRT, correct?
Wife's new SRT is a '16 model and I thought the same as you.
Owners manual doesn't talk about active braking as part of the FCW and I thought it would only yell at you, but it will do full speed lock up braking from as high as 60 mph I've read. Great feature as long as it doesn't put you through the windshield or cause someone else to rear end you in a false alarm situation.

And when it locked up, it wouldn't go immediately either. Once the car stopped (in like 1/2 second) I hit the gas because I knew traffic was behind us, got a dead pedal. Played with gear shift real quick to neutral and back into Drive, still nothing.
Guessing it took at least 2 seconds before I could go again after stopping. Long enough for guys behind me to stop completely, throw their hands up and flip me off a couple times!
Be hard telling your insurance company how it really was your fault that you stopped erratically for no reason and forced tha car behind you to ram into you! Lol

Just like the lane keeping that won't let you drive on the edge of a lane on I 5 to stay on the smoother concrete...
I'll take a low option Scat Pack without these features, no problem.

I have had those situations also with the FCA collision avoidance. Was there nothing in the path or did it just activate even though you had adequate distance?

The car sensed something, but it was 2 right turn lanes, I was in the right, right turn lane, car in front of me had made the turn, we were maybe 100' or less from turning when it sensed a car in the left, right turn lane in front of us (like it sensed I would T bone the car, not knowing Id be turning shortly).
At that point the car hammered the brakes and came to a complete stop immediately. 6 piston brembo front brakes and 275 wide tires, dry pavement, it stopped so hard, ABS was working. Considering this car will stop faster than probably 99% of vehicles on the road, the guy in the 25 year old Toyota behind me wouldn't have stood a chance of not hitting me if he was not for some reason extra far behind me.
100% the car misread the situation.

The failure rate on the automatic system will always be higher than the perfect drivers on the internet.

While I basically said I support these newer systems in my prev post ( not really, but I've learned to drive with it and some situations show the virtues of it, other situations, not so much ), in the case I posted about, the Active Braking would have 100% caused me to get rear ended if the guy behind me wasn't lolly gagging and had been a normal distance behind us.

Welcome to the 21st century, where the other systems like TC, ESC, etc will cut the throttle, apply brakes etc if you start hydroplaning, spinning drove wheels or sliding.
Although I agree with you in theory, it's not the death wish it used to be.

The “collision mitigation braking system”, part of Honda Sensing, in my wife’s Accord can be a little over bearing sometimes but it saved her life once in heavy fog. Wife was on a back country road one morning in heavy fog (a couple of car lengths visible) when the dash lights started flashing and then the car hit the brakes. She didn’t understand what was happening until she saw a truck at the last second head on with her. Some jacka$$ was passing in the fog and swerved back into his lane just missing her. A human eye never would have seen it through the fog. Had the car not slowed he would have hit her head on at high speed. I won’t own another car without it.
