The physical braking system in my Model 3 completely failed this morning.
I didn't realize it until I got on the freeway ramp and almost hit the car in front of me.
Luckily, the regen braking was enough to slow the car down.
The brake pedal felt like it was in a locked position at the top of its range. Could not depress the pedal at all.
This was an absolute critical safety failure.
The car was acting strange from the first moment this morning.
1. erratic window roll down behavior when I opened the front door
2. dark/blank screen upon entry
3. warning message: vehicle hold feature unavailable
4. warning message: 12 v battery must be replace soon
After I rebooted the car, I drove off to working thinking it was nothing.
After realizing the brake failure, I got off the next freeway and exit and drove it back home safely.
With the road side assistance tech on the phone, I tried rebooting the car with no luck.
Then, tried powering the car off via the lcd screen and waiting a couple of minutes seems to solve the issue this time.
The car is now with the Tesla service center.
How could this happen? This was extremely dangerous and I feel very fortunate.
I could have easily found out the hard way at 70+ mph.
Hope this never happens again to me or anybody else, ever.
