2018 RAM 2500 — Complaint #1994114
Open-data reference.
NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE filed May 24, 2024
NHTSA complaint #1994114 (ODI reference 11590583) concerns a 2018 RAM 2500 and was filed on May 24, 2024. The owner reports the failure occurred on February 23, 2021. The vehicle had 80,000 miles on the odometer at the time of the incident. The report was geocoded to Texas based on the filer's self-reported location. The affected component is categorized as service brakes, hydraulic:antilock/traction control/electronic limited slip:control unit/module, one of NHTSA's standardized taxonomy codes used to group defect patterns across make, model, and year.
The filer flagged the following severity indicators: crash: no, fire: no, injuries: 0, fatalities: 0. No crash, fire, or fatality was associated with this report, which places it in the early-warning stream rather than the priority-review stream. Because a VIN was supplied, this complaint is tied to a specific vehicle and not just a model-year cohort.
Individual complaints are consumer-submitted and unverified by NHTSA engineers — the agency's role at this stage is to collect, index, and make them searchable. What matters for federal action is the pattern: when many owners of the same RAM 2500 cohort independently describe similar service brakes, hydraulic:antilock/traction control/electronic limited slip:control unit/module failures, defect investigators have grounds to open a PE and request manufacturer data. Related filings for the same vehicle and component appear below, and the detail page for the full 2018 RAM 2500 shows the complete component-level complaint distribution alongside any active investigations or recalls.
Complaint Description
The contact owns a 2018 Ram 2500. The contact stated that while driving at an undisclosed speed, the electronic service system warning light illuminated, and the ABS, and traction control warning lights also illuminated, causing the traction and cruise control to fail. The vehicle was taken to an independent mechanic, where it was diagnosed with electronic braking module failure. The vehicle was repaired. The contact stated that after the repair the failure reoccurred. The dealer was made aware of the failure and confirmed that it was a known issue; however, no assistance was provided. The manufacturer was not made aware of the failure. The failure mileage was approximately 80,000.
