May be a silly question, but do the lights on the exterior of the vehicle actually come on as well when the flashing occurs?

For the fun of it, what happens if your turn on the signal lights (left or right) while this is happening?

reason I was asking is that the hazards and turn signals work together. In older cars there are 2 flashers. One for the hazards and one for the turn signals.

It sounds like a loose contact or loose wire. The center dash-panel is relatively easy to pop out. I wonder what would happen if you unplugged the hazard-switch.

A wiring diagram might help you chase down where the culprit might be...

Honestly though, this was a problem that existed when you bought the car. They said they were going to fix it, but obviously, they didn't! So, it's not really your problem, it's their problem!

@GuusV That's true - I was hoping to find a needle in a haystack.. I'm just wary of this becoming a recurring issue.

There are usually multiple connectors involved in an electrical circuit. Somewhere in the system, the hazard lights are being activated.
Starting from the signal-light and working your was back to the hazard switch doesn't make sense because the signal light can also be triggered by the signal-switch. So, I'm guessing it is something between the hazard switch and the signal-switch.

You have to start "somewhere"...

I wonder: Do the hazards get activated when a collision is detected? (from watching "stupid driver" videos on YT, I would almost think the answer to that is Yes...)

It could have something to do with the eyesight system yes, but so far no other symptoms are appearing other than sporadic hazards.

- on the evening we brought it back, as it is intermittent, the issue was not occurring. The dealer did not get the issue to reoccur. the dealer replaced that same 'diode/resistor' with another similar model, and they didn't get the issue to reoccur, but on the way home it happened again. seems to only start happening after a while of the engine being warmed up, but this may also be coincidence.

Damn... that's frustrating!

I didn't mean that it has something to do with eyesight. I was referring to the Airbag/restraint system. It would be helpful to see a wiring diagram to see what's involved in activating the hazard lights...
