Driver assistance reportsComplaints are reports submitted to NHTSA by owners and drivers. NHTSA does not verify most reports before publishing them, and a complaint does not establish that a defect exists. Volume is influenced by how many of a vehicle were sold, how long it has been on the road, and how much attention an issue has received.

The rear backup camera has been intermittently failing for over one year on this 2020 RAM ProMaster 2500. The failure has now become more frequent and extended. When the fault occurs, the infotainment screen displays a permanent "Camera System Unavailable" message that blocks access to all other functions including radio, phone, and navigation. The failure occurs in all gear positions and persists after engine restart. The only temporary resolution has been extended power-off periods. The dealer confirmed this vehicle is covered under Manufacturer Recall 59C / NHTSA Recall 25V-552 but stated no remedy parts are available. No written service record was created for this report. No interim remedy or timeline was provided. The recall was issued August 2025 and as of May 2026 remains unresolved. This constitutes a direct safety hazard during reversing maneuvers, consistent with NHTSA's own safety risk description for this recall.
