I suggest to buy a cheap OBD2 reader and if the light comes on again record the code but do not erase it, take the car to the dealer and have them check it and tell them you have proof of the code...
By the way, a "cheap" OBD2 reader may not work - at least the cheap bluetooth OBD2 reader that works perfectly with my ICE vehicles doesn't work with my EV.
I can't guarantee this one will work for the Bolt either, however others have had success on other EV's with this reader:

This might be due to the fact that the Mercedes is using a Tesla powertrain, and Tesla doesn't provide any useful info that mere mortals can access via the diagnostic port.
I've been able to use this reader

with the EngineLink app on iOS to pull and reset codes on my Bolt. And to get data on the battery and charging system (using some of the Volt PIDs).
I've also been able to use the Carista OBDII & app to pull codes.
