There may be an issue with one of the electrical components if your hazard lights malfunction after a jump start, especially after a jump start.
The first thing I would do if the problem occurred is to unplug the switch. There is a problem with the switch if the light goes out. When they still flash, unplug the flasher and make sure the switch circuit is not shorted to the ground.
A short between the switch and the flasher would indicate a problem with the flasher, while a circuit grounded would indicate a short between the switch and the flasher.
Common Hazard Lights Problems
Electric relays control the flashers by switching them on and off the power. Hazard lights can act up if electrical relays malfunction internally.
Relays for turn signals and flashers are used to power the emergency lights. There may be a relay that controls both functions, but they are usually located in the fuse panel in the engine bay.
Multimeters can be used to check if they are operating properly by inspecting and testing them. For example, possibly a wiring issue has caused the problem if they are fine.
It’s possible that there’s an electrical short somewhere that’s causing them to illuminate. However, there is also the possibility that the turn signal or hazard switches themselves might malfunction.
