Tonight, for the second time, my car temporarily lost power brake assist. The symptom was a very heavy/stiff brake pedal, with extended stopping distances (with very heavy pressure, I could stop normally). It felt like an ICE car with a loss of vacuum assist.
The first time it happened (last April) was after supercharging, and the car recovered after two power off/restarts in the parking lot. Luckily, the lot was empty so it wasn't a safety issue.
This time, I didn't notice the issue until I reached the stop sign exiting my neighborhood, and almost rolled into traffic. Normal braking recovered with a power off/restart.
Has anyone seen this? I did a quick search and didn't see anything beyond some preemptive brake booster replacements in 2014.
