but holding down the P button will cause the parking brake to apply, even at 60mph.
It’s astonishing that so many people drive around in 2+ ton vehicles without knowing how they function - without knowing the emergency procedures or what to do when something goes wrong. Read the manual, familiarize yourself with the systems and practice the procedures so you know what to do when the unexpected happens.
Having driven in the time before power brakes became a standard, I do remember the pressure needed to operate them. Under normal driving conditions in a regular car (not having regen) if one expects the feel of power brakes and tries to apply the brakes during a booster failure, it will definitely seem like the brake pedal is locked.
However, in a panic situation like the OP described, I would expect that adrenaline would kick in and one would be stomping on the brake hard enough to overcome the lack of boost.
I would be very interested in the outcome of the service visit. We know that there's a servo on the brake pedal. I'm wondering if there could be an issue with the servo. Again, just wondering....

How about a 1950 Dodge with “three on the tree,” vacuum powered wipers (no washer), no side mirrors, no A/C, bench seats and an analog AM radio? That was my first car. Now I have a Model S Raven.

I know you strive to find any morsel of negativity towards Tesla in your efforts to get them back. But to clarify at least some of the sentiments from this thread that you don’t want to acknowledge; We have many posted threads here from Tesla haters, short sellers, and people that just want to get Tesla back for things they feel have been done wrong to them like yourself.
For that reason, just because someone like the OP says has happened, doesn’t mean it’s factual, as much as you want it to be.
Doesn’t mean it isn’t factual either. As you said, we don’t know.
But you really need to understand that many here are skeptical and will ask clarifying questions because of shorts, haters, and people that want to get Tesla back.
If there weren’t so many of the above folks out there, there likely would be less questions. Hope that makes sense, and helps you understand the other side of the rattle shaking (as you put it), to people asking questions, and why. ...
I have had the same issue as you describe with my model S (2015). I have extensive correspondence with the Toronto service centre on the issue, over the last couple of years, and many visits - including new brake booster, new pads (cold weather type apparently) and diagnostics. Extremely dangerous situation in multiple instances left me wanting to get rid of the car. Last visit they seemed to do something as the problem has not recurred, but they have not identified anything of significance that they did. Still feeling uneasy about the ultimate safety of the car. Having owned probably 20 cars in my life, never have I experienced a failure of the brakes!
Glad you had no adverse outcome!

So you joined here in 2017 and never felt the need to discuss your experience on here until today? That seems unusual to me.
Yes, locked brake pedal, where 'locked' could possibly be the result of a complete lack of power assist - but how could one know what degree of force would need to be applied to the pedal to get any effective braking without boost. As both my wife and I experienced separately, the car just kept on going, no matter how hard the brake pedal was pressed, literally using all the force possible. Then, after a few moments, the pedal would go way down and the ABS would kick in. It was the regen that prevented my wife from rear ending a car on the highway, and that when I forced the issue to a greater degree with the service centre. No have not used the emergency brake, and as you probably experienced, there is little to no time to do so, as a failure of the car to stop takes one by incredible surprise.
Yes I suppose that may be unusual. I've never really posted on any social media before. I only see the TMC notes comes across on my email headers. When I saw this one about the braking it caught my attention.
My Mom's sister had a 196x Mercury Comet that had three on the tree! That's the car in which I learned to drive a stick! And shortly thereafter, learned how to rebuild a clutch!

it's a shame (some) cars don't still have the pull lever between the seats or the e/pedal. Guess the ol' cable notion is a by-gone era.

Yes - I'm sure there are plenty of haters and short sellers out there etc. But the majority of the empathetic responses come from folks who hope/expect their $50,000 or $60,000 Model 3 won't leave them in a lurch. I am the 2nd owner of my Model S - but I still shake my head when I see the original $130,000 window sticker. No way on god's green earth does the car represent that original cost. (And the depreciation is frightening.) In most cases, those who you consider "haters" are current owners who have possibly had issues with their cars and are wanting to know if they're the only ones experiencing that particular problem. The owner of the Model 3 who started this thread had a highly unusual and scary incident. So don't hop on the Elon love-train just yet.

Maybe they weren't comfortable sharing till they heard others have had similar concerns. Some owners might not share because they're afraid of getting the Inspector Clouseau treatment from folks like yourself...
Not exactly.
Pressing the "P" for the "Park" setting while moving will provide an amount of friction to the rear brake pads and rotors so as to slow the car down and then stop it.
Try it sometime, BEFORE you need it for real, so that you'll know how it works . . . .
DARWIN ALERT: Recommend doing this on a straight road with very limited traffic behind you, and it should be NON-wet, NON-icy.
