Hybrid system on other Wrangler years
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: 2014, 2015, 2016, 2017, 2018, 2019, 2020, 2025, 2026.
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

What owners wrote
“When driving my Jeep 4xe hybrid powertrain in "electric" mode, I noticed loss of power at highway speeds, and other times at lower speeds. Pushing on gas pedal doesn't translate to acceleration. Engine kicks on but doesn't have a gear to find. This happens at various speeds, going 25mph up a hill or 55mph on a highway either flat or up a hill.”

Should you keep driving it?
This page can't tell you that. 1 of 87 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.
