Yep, really common. My '02 Sierra does this. Corrosion in the hub plays havoc with the ABS sensor, requires replacing the hubs which I've just been too lazy to do. I ended up pulling the ABS fuse on it which disables the ABS and the brakes work fine (just no ABS function). Haven't experienced it in the Camaro though.

It's weird when it happens, rolling through a parking lot and hitting the brakes, ABS motor going apeshit and the truck still moving.

There is little to no likelyhood of this type of failure happening without a MAJOR failure of either your master cylinder or your brake lines coming apart or your brake fluid gushing out of all 4 corners. For all the electronics and computer controlled devices on modern cars, the actual hydraulic brakes on our high tech, high performance Camaros is the same as it's been on any car for the last 50 years.

If you lose complete braking ability that is a massive failure of the master cylinder or a complete fluid loss. You're losing hydraulic pressure, and it has nothing to do with any of the electronics. Mercedes tried electronic brakes once. It was a disaster. Not ever going to happen again.

I have had similar issues with my 2016 Camaro SS. It occurred twice: both during regular highway speed driving, when braking normally the brakes suddenly stiffened up tremendously and pulsed (the ABS pulse). The message "service brake assist" appeared. After a restart, the car no longer had the issue.

I took it to the dealer and they could not find the code (it was several weeks later). However, I'm taking the car back to the dealer and telling them to look at the TSBs closely because I know there's a software update for this.

It doesn't help that GM was involved in a class action lawsuit about brakes failing on their SUVs.

THIS!!!!!

Not a very ethical thing to do. Say Ford made you a better offer and you took it, and the next owner buys it, has this issue and crashes.

Not cool on any level. NEVER pone off a safety issue like that onto anyone unknowingly, dealer or not.

Not only unethical, but you could be held liable in a court of law if someone else was injured or died from your non-disclosure.

I did not experience anything like this in the 18k/19k miles I had my '16 1SS.

I am not trying to say there is no issue. Simply reporting the point.

What is being described, I agreed with others, as being related to the ABS system. The likelihood of a mechanical or hydraulic related issue is very low. 1. The safety margin on systems like that, from a hyrdo-mechanical design standpoint, are high. 2. You would have clear signs of something going wrong (i.e. leaks, brake dust signs, vehicle pulling, noises, etc.) 3. You would have a systematic, full-out failure - it would not go away and come back...

The description of pulsating/vibration and a lack of feel in the pedal, with very low stopping power describes a situation with the ABS doing "something".

Now, I can relate to the OP and others with this problem: Autocross and ABS "ice-mode":

"Ice-Mode", as people commonly call it, is a phenomenon that can occur with an ABS system when the ABS module sees a deceleration rate quicker than it deems ration compared to the ABS module programming. So, the ABS module will assume the vehicle is potentially on ice and will heavily cycle the ABS or the ABS module will get tripped-out and dump all pressure in attempt to allow control of the tires back to the driver. The ABS is thinking the vehicle's brakes/tires are locked in a skid, rending a driver in a low-control situation. This is something that enthusiasts run into when they place drastically more sticky tires on the car, aggressive brake pads or are overly aggressive with brake applications+overly aggressive with steering/car placement (here lies the importance of ABS systems developed on track car offerings).

What you end up feeling is the ABS will pulse erratically, cease pulsing, the pedal will drop some, the pedal will become stiff/numb in brake feel, and the vehicle will stop (decelerate) at a very low rate, almost nil.

Let me ask this: for those that had the issue, was it seen during or even right after a hard rain?

The issue I see is the OP makes some big claims in his Threads and never comes back to shed any light on the results.

If there’s multiple 2016 owners experiencing this and ONLY 2016 owners experiencing this, those owners should see if their build dates are similar (within a month, I’d say). It’s very common for a supplier to provide a manufacturer with a bad batch of parts, or for a manufacturer to make their own bad batch, and those parts get put vehicles over a small time period. If y’alls build dates are close, you should contact your dealers and ask how you inform them of the issue that may require a recall to fix.

Especially when you are painfully unhappy, but have only posted 7 complaining messages in a couple of years.

This also happens when going over railroad tracks or a long stretch of rough, choppy pavement where the tires are constantly moving up and down (and occasionally leaving the pavement) to the extent that the ABS senses a lack of traction and kicks in.

I'm fairly experienced with brakes, doing bleeds, etc. If the pedal is going to the floor, there is air in the system and fluid has gotten out of the system. It's a simple matter of things that occupy space. I think I remember seeing a thread very much like this in the BMW forums too, I guess it happens from time to time. Thing is, brakes are pretty simple mechanical devices, operating on hydraulic advantage. Everything happens for a reason, well, except when it doesn't...

Did your car loose power when this happened at low speeds? Or start to idle way below the normal 750 rpms or so it should be at?

Thread is 10 months old. OP is probably in a Mustang by now.

true, but wanting to note one thing many overlook, GM does the same thing when they lemon cars. They are resold to the public regardless of their defect.

If ABS fails you just have regular brakes that will lock up in hard braking or inclement weather, and nothing more than a check ABS light on your dash. An ABS failure is not catastrophic by any means...... some serious, seasoned high performance drivers may actually prefer no ABS as they are experienced in brake lockup threshold feel and can modulate the pedal quite well on their own.
