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 module (14 reports), the battery (13 reports), the wiring (12 reports) and the sensor (3 reports).
Recalls and investigations
3 recalls on the electrical system cover the 2018 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 powertrain control module may be equipped with a voltage regulator chip in the circuit board that may fail, causing a stall or a no start condition.
These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging.

“My car randomly illuminates every light on the dashboard and my speedometer will say zero mph and I lose all power steering and have to put my car into neutral and roll to a stop because my brakes wonât work either. Then I cannot turn off the ignition or accessory. Check engine light is on and my car starts but there are no brakes or power steering. Thankful my kids were not in the car!”

Should you keep driving it?
This page can't tell you that. 0 of 68 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.
