Warning lights on other 1500 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, 2020, 2021, 2023, 2024, 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 (12 reports).
Recalls and investigations
One recall on the electrical system covers the 2022 model year. A recall on the same system isn't always the same failure, so read the defect text.
These vehicles may have been built with incompatible heating, ventilation, and air conditioning systems (HVAC), resulting in the windshield defrosting and defogging system being inoperable to drivers.

What owners wrote
“The check engine light and the battery warning lights came on. Took it to the dealership and they diagnosed the problem to be the MOTOR GENERATING UNIT (MGU). This is a known problem with the ram truck. The parts to fix it are on back order at a minimum of 45 days.”

“Multiple lights going off all at once, including ABS, four-wheel-drive, towing, Lane assist, collision, etc. I have had this vehicle to the local dealer for this same complaint, and nothing was found, condition resolved itself. It has returned just a few months later. During this episode, the speedometer and tachometer do not work, nor do turn signals.”

Should you keep driving it?
This page can't tell you that. 0 of 26 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.
