Interesting ABS issue

I was running errands around town today and while maneuvering through a gas station parking lot I went over one of the raised covers they use to refill the underground tanks. I didn't hit the cover particularly hard but enough to notice the bump. As I pulled out onto the street I noticed my ABS warning light was on in the bottom right corner of the dash. I figured it would turn off by the time I looked away so I paid it no mind. Approaching the next stop I noticed the brakes felt weird. It felt like there was no regen braking and it took extra effort to come to a stop. While navigating the next parking lot I watched my dash more intently and noticed there was no regen occurring while I tried to brake and the brakes were extra touchy yet required more effort to slow the car down.

I pulled into the Costco gas station and turned off the car while waiting for a pump to open up. I started the car within 1 minute or so and the ABS light and traction light (top left corner) were still displayed. The brakes still felt weird. I pulled up to a pump and shut down the car. After fueling up I started the car and the lights were gone; the brakes felt normal again.

So did the "manhole" cover cause the issue or could it be that the Torque app caused a glitch? I noticed that the Torque app was not actively monitoring while I sat at the Costco station. It had somehow become disconnected. I made sure to turn it off before restarting the car after fueling up.

Weird situation and potentially dangerous with the wrong driver in the wrong situation.
