Warning lights on other 2500 years
No other 2500 model year has enough reports of warning lights for a sheet of its own. See every 2500 year.
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 (9 reports).
Recalls and investigations
One recall on the electrical system covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
These vehicles are being recalled to address a defect that could prevent the cruise control system from disengaging.

What owners wrote
“ABS warning light flashes then Traction Control will flash with a bing-bong noise. Now a few days later the 2 lights come on at startup and stay on. Bing -Bong noise is intermittent. Cruise Control will no longer engage. Model 2018 2500 Laramie crew cab with 122K miles. My concern is braking when pulling my 5th wheel. I think there is an investigation working right now. Investigation: PE 22-012”

“Service electronic braking system / ABS service antilock brake system. Both these lights come on and ding, half a second later they are off. This happens non stop, looks like everyone is having this problem. This should be a recall not a $1200 fix. I only have 58,252 miles on my truck. This problem for me has been going on and off for 2 months.”

Should you keep driving it?
This page can't tell you that. 1 of 47 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.
