Report counts are for each model year on its own, so a newer car has had less time to collect them. Model years with too few reports of it for a sheet: 2021.
What this problem usually is
These reports come from hybrid, plug-in and electric vehicle owners whose car put up a system warning and lost power, sometimes dropping into a reduced-power mode on the road. Others describe a car that won't charge, a high-voltage battery or inverter replacement, or a problem that turned out to be the ordinary 12-volt battery all along.
What got replaced
Owners who name the part that was replaced mention the drive unit (3 reports).

What owners wrote
“While traveling 40 mph, car flashes a warning, "Check Hybrid System", and then the car shuts off. No power steering and brakes are difficult. The warning is only 3-5 seconds before everything shuts down. This is definitely a hazard to myself and others. If in traffic at higher speeds, there would certainly be an accident with devastating results.”

Should you keep driving it?
This page can't tell you that. 0 of 44 reports involved a crash. Owners who file are the ones who had a bad experience, and nobody checks their reports. If the problem affects steering, braking, power or a fire risk, treat it as a safety fault and have it inspected before a long or high-speed drive.
