Remember that a hot relay means bad contacts which means voltage drop and and/or unstable voltage and even arcing across the connectors.

This in turn means unstable power to everything downstream from the relay.

How the unstable power will affect the downstream components depends hugely on their design and when and how the unstable power occurs.

So definitely a problem you do not need, and good that you sorted it out.

Only time will tell if it was the root cause of your random stalling of the engine.... drive it for a few weeks and give us feedback...
