Each component in detail
What the reports in each category say, in the owners' own words
Brakes
Reports naming service brakes, the antilock braking system, brake hoses, master cylinders or the parking brake.
From owner reports, verbatim
The bike randomly goes into limp mode. When codes are pulled they are always the same ECM and ABS codes. Took the bike to Harley Dealer they said they couldn't find anything wrong and couldn't duplicate it. It's happened four times now. Leaving a stoplight and entering a freeway are two examples. There is no warning before going into limp mode.

Driver assistance
Reports naming forward-collision avoidance, lane keeping, back-over prevention, cruise control and related electronic driver-assistance systems.
From owner reports, verbatim
This is my second report on 2021 street glide special. Bike goes into limp mode whenever it wants to. This has happened at idle at a light, driving 25 MPH in town and running at 65 MPH on the freeway. Bike was at the dealer for a month in 2022 and they claimed nothing was wrong. The first time was at 13,000 miles, Bike is currently at 28,000 and problem still here. Check engine light comes on and codes all run you in circles. Resetting ECM seems to be a short term fix. This is a very dangerous problem that needs to be addressed.
