l know if you turn it off it comes back on next time you use the vehicle.
But there's also an option to adjust the sensitivity of the system. You could try turning it down and see if it remembers that. lt's happened to me once, when l was in the middle of the road turning right, and it didn't like how close the car was coming the other way. Braked violently. At first l thought l had been hit from behind! |

It seems to be random how and when it activates. I've had it activate when no other vehicle was around! I really don't trust it not to actually cause an accident! Eiger Grey MY23 D250 SE with bits. Known as Noddy.

I’ve had mine activate recently after driving through clouds of bugs. This year seems to be worse than recent years too for them - frequent cleaning of the top of the windscreen around the cameras seems to cure it and unfortunately the wipers seem to be totally crap at removing their remains……..

Not to hijack the thread, but my wipers are utterly useless. I ended up cleaning the bugs off by hand and when I tried to use the wash/wipers the following morning they didn’t even have the strength the clean off the water marks!
Back on topic, I got the shock of my life when the emergency break assist triggered on mine a few days back. |

I thought you could adjust the sensitivity ? but not turn the system off Mike

You can turn it off but you have to do it every time you start the vehicle.

The AEB request for braking can be overridden by a turn of the steering wheel or press on the accelerator.

Both the cameras (above the rear view mirror) and the forward facing radar (on the front bumper) are used for the AEB system. 22MY Defender 110 D300 S in Pangea Green and Contrast White Roof

Do these systems also provide any form of rear collision avoidance? For example, if you are stationary can the system detect that something is about to ram you from behind and (if there is space in front) move smartly forwards?
I suspect that when we have a significant number of vehicles on the road which randomly and spuriously start to brake as hard as technology allows, we are going to have a spate of rear end collisions from the kind of idiot that follows too closely behind. I was always brought up to believe that there is no excuse for hitting the car in front, but nowadays that seem to be challenged, with "cash for crash" scammers and "brake checkers" being held liable. What is the score if your vehicle autonomously decides to "brake check" the vehicle behind? I predict a period of chaos before leaving a sensible distance to the car in front become the norm again! It will also be interesting to see the domino effect when a whole line of semi-autonomous cars takes collision avoidance action because the one at the front of the queue has braked hard. |

Glad I'm not the only one who finds it frustrating/dangerous. I fully agree it's going to cause accidents.
There is a sensitivity option - where I can make it even MORE sensitive/proactive. The default level is 'normal' and it wont let me go any less sensitive than that. I will definitely try an input to cancel the braking in future. In both instances, I was rolling along in traffic with plenty of room so I didn't actually need to brake, accelerate or steer. I will try it next time though - anything to prevent this violent skid to a halt. Thanks Nick |

No issues here. Beginning to wonder if mine works, as I seem to be the odd one out. 24MY 90 D250 HSE, Tasman Blue

Yep no issue here either, the rear collision avoidance system did work when I was reversing out of a spot and a young lad came flying past on a bicycle, I didn't see him but thankfully the car did

Yes. It is called "Rear Collision Monitor." I've never experienced this alert though. It also does not smartly move forward, just flashes the brake lights. I have experienced gongs and warnings from the "Rear Traffic Monitor", that Hairy Dan mentioned, in tight car parks. Reassuring piece of assistance tech, to supplement your own eyes and judgement. Never found it to be too sensitive.

Not much help to the debate here, as I've got conflicting opinions of this "nanny state" technology!
The positive vote comes from an incident a few months ago on a dark morning, reversing out my driveway, admittedly not paying enough attention to notice that some clown had parked his black car across my gates, the rear collision thing did its stuff and stopped me in my tracks before I smacked into the side of it. On the negative side however, reversing a trailer the other day, opened the drivers door to lean out and gauge the distance to the wall I was backing up to. No, no, no we're not having any of that said the car as it applies the brakes, goes into Park and bongs away to its hearts content! I had to close the door and put my seatbelt back on before it would move again. I swore at it a lot for that!!  |
