NHTSA Complaint #11713339 — 2020 RAM 1500

Vehicle experiences intermittent but repeatable safety-related electrical failures affecting turn signals and blind spot monitoring. The left turn signal remains engaged after canceling and does not shut off unless the opposite turn signal is activated, causing incorrect signaling to other drivers. This occurs without driver input. At the same time, the Blind Spot Monitoring system intermittently displays a “Blind Spot System Unavailable” warning and disables the safety feature while driving, increasing the risk of unsafe lane changes. Vehicle was inspected and diagnosed by an authorized Ram/Stellantis dealer. Dealer verified the concern and documented fault code B2225-00 – Steering Column Module Internal Failure, confirming the steering column control module is malfunctioning internally and not posting correct left/right turn signal inputs. Wiring, grounds, power, and CAN bus communication were inspected and ruled out. Dealer also documented fault code B285F-15 – Blind Spot Warning Light Control Circuit Short to Battery/Open, tracing the blind spot failure to a shorted passenger-side mirror harness, confirmed through load testing and a wiggle test. No aftermarket electrical modifications are present. These failures affect federally required signaling and driver-assist safety systems and occur intermittently, making them unpredictable and hazardous. Vehicle has approximately 48,877 miles and is a 2020 Ram 1500. Concern is ongoing and unresolved without replacement of safety-critical components.
