Automatic emergency braking will be standard in most cars in 2022. The technology is expected to cut the number of rear-end crashes in half, but hundreds of drivers say sometimes the system slams on the brakes apparently for no reason.
CBS News found reports of several accidents and injuries that drivers blamed on false activations of emergency automatic braking systems. Safety advocates and carmakers say in the vast majority of cases it works, but it is not perfect.
For Cindy Walsh, getting behind the wheel of her 2018 Nissan Rogue raises her anxiety level. Since she bought the SUV new last October, she told CBS News correspondent Kris Van Cleave it has slammed on the brakes three times for no clear reason when she said there was no risk of a collision.
"The first one, I was driving down a four-lane highway going about 55 and it completely came to a complete stop," Walsh said. Now she said she's scared to drive the car, so she doesn't drive it.
Walsh took it to the dealer each time. Twice, she said, they told her they fixed it.

Lol. Well said DR.
Any truck with auto-braking would have anti-lock braking. No way did it do what he implied.
I have had it happen, period.
The KEY word is KEYLESS
In the glorious future, the only people who will need to know how to drive will be the chauffers of the elite.
Meanwhile, a buddy of mine got a new Honda minivan and we took it cross country last summer. It had the nannies, and I have to say it made the long drive more tolerable.
I still hate it, though, and it makes me think I need to acquire my “last car” before it’s too late.
Yea but if the fuse blew on your anti-locks your regular mechanical/hydraulic brakes would still work.
He was talking mainly about these new electronic emergency brake systems.
Unlike new toyotas with their old style mechanical foot pedal emergency brakes many manufactures now have new electronic push button emergency brakes.
many report of them actuating while people are driving or not actuating when people really need it.
“The KEY word is KEYLESS”
Yes. With the KEYLESS fob you can unlock the door and start your car even with a dead fob battery!
“I have had it happen, period.”
What? Let your bias outweigh your knowledge?
Does not on a Honda
My Willys jeep’s steering box is worn out and it will seek a lane. I adjusted the box as much as it would allow.
It’s on the list of things to finally fix. The old trap is partly apart now. I work on it when possible.
“He was talking mainly about these new electronic emergency brake systems.”
So your previous post was misleading?
“in essence brakes should NOT be controlled by electronics of any kind.”
Add that to my list of uses.
“Plus, when you are out in the boonies or a bad neighborhood and your keyless battery dies or malfunctions, you walk.”
No you don’t.

Well if electronically controlled emergency brakes suck, replacing replacing the direct connection via hydraulics, cables etc with computers, wires and servo’s wouldn’t it seem that using the same style systems for actual daily braking be a bad idea?
Give me the old style any day...add anti-lock.
Even when that breaks my car will still brake.
:)
As an example, I had an accident caused by an ABS doing its job as designed. One wheel was on a steel plate in wet weather, the others on pavement with good traction. The ABS system prevented the three good wheels from stopping the car and I slid into the car in front of me at about 7 mph. Did a lot of damage for what would not have been an accident without ABS. One wheel properly braking would have stopped the car.
I have slid down roads in white knuckle rides in winter with ABS when, again, one good wheel with some small amount of traction would stop the car.
For those of us not driving 140 mph on the Autobahn and needing to brake while going around a curve, It's a stupid concept and a stupid design.
Smart engineers know that the world is a lot more complex than anyone can predict. It's the second level down who think they are a lot smarter than all the rest of us who get us all into trouble.
Go home to have lunch and guess what showed up on the AVWeb site? Story is finally beginning to leak out. You better get busy because you’ve got lots of people that need correcting, apparently even the Indonesian FAA:
First Airplane
The committee said it couldnt determine if the installation of a repaired AoA vane was properly tested, but it said the mis-calibration wasnt detected and the airplane took off in an unairworthy condition. The sensors calibration was 21 degrees in error, according to the report. The investigation revealed lack of documentation in flight and maintenance logs such that the accident crew was unaware that a flight the previous day had experienced runaway trim due to the faulty MCAS. That crew disabled the stabilizer trim system after the faulty MCAS activation, but it didnt report the fault once it landed at the destination.
Second Airplane
The report said the pilots of Lion JT 610, the accident aircraft, were distracted by multiple alerts, repetitive MCAS activations and numerous ATC communications and didnt manage the emergency effectively, partly because of poor crew resource management. The committee noted that these deficiencies had been identified previously in training and reemerged during the accident flight. When the MCAS activated, it took the first officer four minutes to locate the proper checklist because he wasnt familiar with required memory items. During training, the same pilot had shown unfamiliarity with Boeing and airline standard operating procedures and had weak aircraft handling skills, the report revealed. Although the FO was experienced in the 7374286 hours in typehis training record reflected numerous deficiencies, including major problems controlling the aircraft and being too rushed and too rough with the controls on approach.
“As an example, I had an accident caused by an ABS doing its job as designed. One wheel was on a steel plate in wet weather, the others on pavement with good traction. The ABS system prevented the three good wheels from stopping the car and I slid into the car in front of me at about 7 mph.”
Each wheel has a sensor and controls that wheel in cars. Your description of the event does not fit.
Also, the use of the word ‘slid’ is strange.
“many report of them actuating while people are driving”
Possibly but I have never heard of any.
“these new electronic emergency brake systems.”
They are parking brakes.
