2015 Jeep Wrangler vehicle speed control problems

“In October 2025, the Anti-lock Breaking System (ABS) Brake, traction control, downhill control indicators all illuminated. This also impacts cruise control and acceleration from a stopped position. My repair technician placed an order for the necessary ABS control module with MOPAR. The expected delivery date was August 2026. In August 2026, MOPAR informed them the part was on a nationwide back order with no ETR for resolution. I placed an order for the ABS Module in August 2026, with a suggested date of delivery in two weeks. MOPAR has advised us today 18 August 26, there is no ETR for this critical component to be available. Anti-lock brakes are federally mandated in all vehicles 2012 and beyond. Not having this module disables multiple required safety components in the vehicle not just ABS and puts the consumer, other drivers at risk.”

“The dash lights constantly indicate that the ABS and traction control systems are activated. The vehicle is also producing code c1073, indicating that the ABS control module must be replaced, however MOPAR does not have any replacements, new or rebuilt, available.”

“Traction control, ABS, and brake light all illuminated, then on 5/3/2026 while driving the speedometer quit completely. Replaced all 4 wheel speed sensors to see if it would help and nothing changed.”

“Jeep Wrangler JK ABS Module Issue: History, Stellantis Response, and Safety Concerns Background: The Discontinued ABS Module Problem Jeep Wrangler owners (particularly Wrangler JK models from 2011–2018) have been plagued by failures of the Anti-lock Brake System (ABS) control module – a critical component that controls the vehicle’s anti-lock brakes and stability control. The problematic part is commonly referenced by Mopar part number 68259556 (with revisions AA, AB, AC, AD, AE for 2014–2018 Wranglers). In recent years, this ABS module was discontinued by the manufacturer and put on indefinite backorder, leaving owners unable to obtain a replacement when the unit fails. The issue isn’t isolated to just one part number or model – similar ABS module shortages and failures have been reported in other Stellantis vehicles (including later Wrangler JLs and even Ram trucks) as well. Stellantis (the parent company of Jeep, formerly FCA) has not provided new stock of the module for an extended period, creating a nationwide shortage that has frustrated many customers and raised serious safety concerns. Timeline of the Issue and Part History Owners and mechanics first…”

“To Whom It May Concern, I am submitting this letter as a formal complaint regarding the unresolved unavailability of a safety-critical ABS module for my vehicle and the improper closure of my case by Stellantis without escalation. Vehicle Information: 2015 Jeep Wrangler Unlimited Sahara ABS Control Module Dealer Documentation: On January 15, 2026, I received written confirmation from Texan Dodge in Humble, Texas, stating that: • ABS Module #68259556AD is currently on backorder • That dealership alone has 15 pending orders • There are 300+ customers nationwide currently in the supply queue • No ETA or ship date has been provided by the supplier This documentation demonstrates that the issue is systemic, not isolated, and not resolvable simply by prepaying a dealership order. Case Handling Concerns: Despite providing this information and formally requesting escalation, the assigned Stellantis case manager stated that she intended to close the case and refused to forward it to the next supervisory or corporate review level. The case was closed over my objection while the issue remains unresolved. Core Issues: • The ABS module is a federally required safety…”
