Brake 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 got replaced
Owners who name the part that was replaced mention the module (175 reports) and the brake fluid sensor (13 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.

What owners wrote
“ABS warning lights came on took the truck back to the dealer (approx 54000 miles) replaced abs pump unit and would not cover under warranty as it was out due to miles. Now again at 108000 I am getting abs warning and electronic brake system warning This is clearly a repetitive brake safety issue and a recall should be enacted”

“This is the second time the antilock brake control module has failed and this truck has less than 75k miles on it. The warning lights constantly come on and off and if I needed to brake I am not sure that my antilock brake system would work.”

Should you keep driving it?
This page can't tell you that. 11 of 668 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.
