Friends, this just happened to my friend this afternoon, running at about 100km (62mph), mannetino at “WET”. out of nowhere all the brakes locked up and led the car to the guard rail. the brakes just locked up literally while the car running!!! anyone experienced this???

Goddam that is absolutely nightmarish !!! I'm glad you're safe That should never happen, I hope you'll find out the exact cause of this
Tell me about it, its unheard off, there was no error or anything ahead of time. simply, cruising, then there, it stopped just like that. it drifted then there, bang, rail guard... At the pictures, the caliper is still biting the carbon disc.... Sent from my iPhone using FerrariChat
what are the pictures of the brakes intended to show? does the car roll in neutral, or are the wheels still locked?
It can happen when stepping on the throttle in wet conditions. In all newer cars, the stability control computer will brake some wheels to avoid spin outs. At 60 mph things can get interesting fast.
This is totally unheard of and never reported before, as far as I know. Makes me paranoid to drive my F12 in 'wet'.
So I'll be the first to say what most are thinking....60 mph in a 700+ hp rear wheel drive car on a wet road and into the guardrail....gotta be the car
Agreed, never heard of it, Never experienced it, and also consider it highly unlikley. Pity about the vehicle though
New systems screw up but driver blamed. If lucky it is in the last 10sec of data recording. Friend had this happen when hus bmw autobraked making a left in a 2 left lane road. Fast closing second car racing to make light appears on his right lane turns left each driver in own lane. Despite bmw left steering angle and constant speed the bmw saw the other car on right and auto slammed brakes.
There is a whole science on confusing automated systems. I forget the name of it. Start searching around. Trying to pick out A stop sign is much harder than you think
Even if the electronics make an unwanted decision to brake, the ABS should prevent the wheels to lock - so the system has to be completely screwed up to get into such situation. The issue with the pseudo intelligent software introduced on cars (for driver aids, autonomous driving and so on) is that it's as complex and for whatever reason is very far away from the enforced quality standards for trains or aircrafts (although experience has shown even for these there could be serious problems).
my mom has a newer Lincoln SUV, she had the brake pedal go to the floor, luckily no accident. dealer denied and denied, she's 80 years old and they actually shamed her she did something wrong. In 30 seconds I found reports and documentation online about the problem with booster.
I had a scary moment with my Tesla a few months ago when the car literally slammed on the brakes on a side street with nothing in front of me. Scared the crap out of me. Definitely would have been hit in the back of somebody was behind me. Sent from my iPhone using FerrariChat.com mobile app
I too recently had a super scary moment when my six months old 2020 AMG GLC 63S suddenly and for zero reason brake locked and came to a total stop (I was brutally flying into the seat belt). I had no chance to do anything, it happened so quickly. And there was no object or anything else on the road, and no other car. And fortunately nobody behind me. I was just driving approx 45 miles/h. Nothing happened. But all these super engineers tell us about the great nannies and new functions and the Mercedes cameras and radars are not even able to properly identify speed signals?? .......at least 50% or more are totally wrong. And all these super clever guys talk about autonomous driving? What a total nonsense. Total b.s. Marcel Massini
Even good old-fashioned ABS can get you into a heap of trouble. We were crawling down a steep icy road with a couple of tight curves. Half-way down the ABS decides to release the brakes and we were off to the races. The car sped up to 40 mph while standing on the brake pedal. We barely missed the guardrail on the bottom of the hill. A fried was not so lucky. He hit a curb at speed as the ABS would not allow lock-up. Took out his entire front suspension, bearings and wheels. Sometimes it is preferable to lock up the wheels and slide vs. building up a lot of momentum. But you do not get a choice with ABS.
or just a matter of time https://www.theverge.com/2019/8/15/20805994/ups-self-driving-trucks-autonomous-delivery-tusimple https://www.cat.com/en_US/articles/customer-stories/built-for-it/thefutureisnow-driverless.html https://www.dcvelocity.com/articles/44254-driverless-forklifts-are-now-a-thing Granted, these aren't full Level5 autonomy (go anywhere) cars, but they are examples of autonomous vehicles already operating today. I wouldn't write this work off out of hand, there is too much money to be made. (And yes, there are a lot of people who won't have anything to do with them.)
A driverless forklift in an unmanned warehouse is something quite different than an Italian V12 engined sportscar with 740 hp on a regular open road and cruising at speeds in excess of 100 mph. Marcel Massini
Similar thing just he other day in my '18 E63S. I saw the traffic ahead , My car's warning beep went off , I was ready to brake and then the darn thing decided to break hard on it's own , I cringed bc there were cars on my rear . In the instant the traffic ahead of me moved up I wanted to move up too to give the guys behind me more room but the damn system wouldn't let me go , it was still brake locked ! I was literally cringing waiting for a bump from behind , luckily they stop. Scary I'm an engineer and I can't fathom that some of these system issues exist. Sounds like a failure of System design analysis 101.
FWIW, my Honda constantly thinks I'm getting into a head-on when I travel on two lane roads with traffic going in both directions. It also likes to slam on the brakes when I pull off a highway onto an exit without using the blinker. Thankfully, you can override the auto-brakes pretty quickly using the accelerator pedal. My daughter calls the car "bossy".
You're right, they aren't there yet, but they are inching up on it. "Self-Driving Race Car Set a New Speed Record After Topping 175 MPH" https://robbreport.com/motors/cars/roborace-robocar-speed-record-2868060/ This car has over 720HP through 4 electric motors. No place for a driver. And for a little different take, Stanford University project doing some drifting at a local track, the interesting parts starts after about the 30sec mark:
Just this morning I was leaving the parking lot and opened my Alfa door as I was rolling past the dumpster to throw paper towels into it - just creeping along at 3-5mph and the car put the e-brake on and slammed to a halt. Thankfully low speed but I didn't know it would engage automatically when the door opened.
