2018 RAM 2500 — Complaint #1991418
Open-data reference.
NHTSA Complaint about SERVICE BRAKES, HYDRAULIC:ANTILOCK/TRACTION CONTROL/ELECTRONIC LIMITED SLIP:CONTROL UNIT/MODULE filed May 14, 2024
NHTSA complaint #1991418 (ODI reference 11588662) concerns a 2018 RAM 2500 and was filed on May 14, 2024. The owner reports the failure occurred on October 31, 2022. The report was geocoded to Ohio 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 while driving 55 MPH, an alarm sounded, and the ABS and traction control warning lights illuminated. The contact stated that the failure had been recurring while driving, causing the ABS and the cruise control features to become inoperable. The contact stated while driving and slamming on the brakes on several occasions to come to a complete stop, the ABS was inoperable, causing the tires to lock and the vehicle to slide. The contact who is an independent mechanic, diagnosed the vehicle and determined that the ABS module had failed and needed to be replaced. An unknown dealer was contacted for parts several times and informed the contact that the part was on backorder. The vehicle was not repaired. The manufacturer was not notified of the failure. The failure mileage was unknown.
