2018 RAM 2500 — Complaint #1972435
Open-data reference.
NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE filed March 4, 2024
NHTSA complaint #1972435 (ODI reference 11575371) concerns a 2018 RAM 2500 and was filed on March 4, 2024. The owner reports the failure occurred on August 1, 2023. The vehicle had 78,000 miles on the odometer at the time of the incident. The report was geocoded to Colorado 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.
