I'll describe it again in as much detail as I clearly remember, and maybe someone will see something new:
I had just gotten the car safely to the side of the road after the problem happened the fourth time. I knew that the car's sensors had reset one of the times prior, after being turned off...
Yes, this is what happens.
The brake issue has happened to me technically 5 times, and all were more or less exactly what u/emailjillianne described, with the exception of one time, that I didn't even consider of note, but it might help diagnose the issue. My initial post mentioned 4 times...
Having very similar or exact same problem in Southern California with my 2016 Spark EV. 4 times it has happened. It is currently in the shop being "fixed" for the 4th time.
Chevy/GM repurchased u/emailjillian's car the first time, and is discussing canceling the lease remainder on our car...
