ABS light on on other 2500 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, 2019, 2020, 2021, 2022, 2026.
What this problem usually is
This is the narrower sheet inside brake problems for the anti-lock brake (ABS) warning light. What separates it from the wider brake sheet is that most owners here aren't describing worn pads or grinding. They're describing a light, and often a list of features that quit along with it.
What got replaced
Owners who name the part that was replaced mention the ABS module (609 reports), the ABS pump (265 reports) and the wheel speed sensor (12 reports).
Recalls and investigations
One recall on the brakes covers the 2018 model year. A recall on the same system isn't always the same failure, so read the defect text.
The hydraulic control unit (HCU) may fail, which can cause the anti-lock brake (ABS), electronic stability control (ESC), and traction control systems to fail.

“The âService Anti-Lock Braking Systemâ warning turn on and off intermittently and the yellow âABSâ and âtraction control offâ icon turn on and off intermittently about every 4-5 seconds. In the morning after first start, the warning lights and message proceed after the first brake pedal application. I have 78,500 miles on the truck.”

“My truck has 32000 miles on it. Its just out of warranty and the ABS Hydraulic Control Unit is out again. This will be the third HCU put into my truck. This is a known problem from Ram and it has never been addressed. NHTSA please have RAM make it right and fix the problem so costumers are not spending 1500.00 every 15,000 miles.”

Should you keep driving it?
This page can't tell you that. 20 of 2059 reports involved a crash and 1 people were hurt. 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.
