NASA says that the likely cause is an internal short stemming from the Radioisotope Thermoelectric Generator (RTG) the rovers nuclear power source.
RTGs have been commonly used on many NASA missions that also experienced occasional shorts and that had no long term impact or loss of capability on their flights.
This type of intermittent short has been seen in similar RTGs, including the one on the Cassini spacecraft, which has been orbiting Saturn for years. The rover electronics are designed to operate at variable power supply voltages, so this is not a major problem, says Curiosity team member Ken Herkenhoff of the USGS in a mission update.

That’s what happens when there’s no one there to jiggle the wires.

Ahhh. . .maybe some”one” did take it off-line to service it and then brought it back on-line.
I think I saw one of the last pictures and there was a blue shirt with a wrench on it in front of the lens. . .

I’ll bet they tried to start it when it was in “Drive” again.

It wasn’t a glitch, it was a DUI.

Tree trimming crew shorted the power line across the cable. It set the neighbor’s house on fire.

Reactivation Code: “Red Rover, Red Rover.”
Amazing & a testament to its design that it keeps operating in that environment, and well beyond the specs ...
