Warning lights 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, 2020, 2022, 2023, 2025, 2026.
What this problem usually is
This sheet is for the moment the whole dash lights up at once: a string of warnings for systems that seem to have nothing to do with each other. Sometimes features drop out. Sometimes it's all gone on the next start. When that many systems complain together, it makes sense to look first at what they have in common.
What got replaced
Owners who name the part that was replaced mention the battery (14 reports), the module (5 reports) and the wiring (3 reports).
Recalls and investigations
3 recalls on the electrical system cover the 2021 model year. A recall on the same system isn't always the same failure, so read the defect text.

The instrument panel cluster may experience an internal short circuit and fail. As such, these vehicles fail to comply with the requirements of Federal Motor Vehicle Safety Standard number 101, "Controls and Displays."
The high voltage battery may fail internally and lead to a vehicle fire while parked or driving.

Is this a known problem?
The manufacturer has sent NHTSA 1 service bulletin or notice for the 2021 Jeep Wrangler that deal with this problem. Newest first.
Federal rules make a manufacturer send NHTSA a copy of any notice about a defect that goes to more than one dealer or owner. Most of these are service bulletins, the repair instructions manufacturers send to dealers. NHTSA generally leaves safety recall bulletins out of this file, and recalls are listed separately.

Should you keep driving it?
This page can't tell you that. 2 of 34 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.
File your own report with NHTSA. Complaint counts are how a problem gets an investigation. How reports land on this sheet.
