Automotive giant Chrysler has launched a large-scale recall in the United States due to a serious technical defect in trailer hitch control modules. This issue affects both vehicles that have just come off the production line and Mopar replacement parts, approximately... 456 thousand vehicles and involves thousands of electronic modules. According to NHTSA data, this is considered a risk factor that directly threatens road safety.
Critical Failure in Trailer Brake and Lighting Systems
The source of the malfunction is an electrical overload caused by a hardware error in the trailer tow module. This overload causes the module to fail, preventing the trailer's turn signals and brake lights from working. Even more critical is the complete loss of brake control in configurations with trailer brakes. The fact that drivers receive no warning when this malfunction occurs is a major risk factor inviting accidents.
Affected Models and Mopar Spare Parts
The recall is proceeding in two phases. The first phase focuses on Mopar modules manufactured between 2024 and 2025 and used as spare parts in service centers. The second and more comprehensive phase will cover modules manufactured between 2023 and 2025. RAM 1500, 2500, 3500, 4500 and 5500 with pickup models Jeep Wagoneer S and new Jeep Cherokee FCA acknowledges that the modules installed in these vehicles are not protected against voltage fluctuations.
Road Safety and the Solution Process
FCA is aware that the malfunction poses a significant danger to other drivers, as the failure of the trailer's brake lights makes it impossible for vehicles approaching from behind to detect maneuvers. While no injuries have been reported yet, the company aims to inform all owners by the end of March 2026. As a solution, the faulty units will be replaced free of charge at dealerships with new versions featuring revised protection circuits. This incident once again demonstrates how a single small component can create a significant safety vulnerability in a global supply chain.
