NHTSA Complaint #11698934 — 2025 RAM 1500

Date: November 12, 2025 Vehicle: 2025 Ram 1500 Big Horn 3.0 Dealer: Frank Boucher Chrysler Dodge Jeep Ram of Janesville – 4001 Milton Ave, Janesville, WI 53546 I have been experiencing ongoing electrical and instrument cluster failures with my 2025 Ram 1500 Big Horn 3.0 since purchase. The most serious issue is a recurring message: “Warning Light Illumination Cannot Be Shown – Service Required.” This means the cluster cannot guarantee display of safety alerts such as the check engine, airbag, brake, or oil pressure lights. This is a major safety hazard because I may not be warned of a system failure while driving. The truck also shows false “Trailer Light Out” warnings when no trailer is connected, indicating a fault in the Body Control Module (BCM) or CAN bus communication. This may cause incorrect trailer or brake-light behavior, putting other drivers at risk if brake or turn-signal lighting fails to operate properly. It also displays a false “Too Much Oil” warning despite normal levels, and the 3.0 engine has no dipstick, preventing manual verification. The truck has also failed to start multiple times with both the remote fob and manual ignition. On November 12, 2025, it would not start at all; after several attempts, it started with the check engine light briefly on, then it turned off on its own. I have brought the vehicle to the dealer twice. Technicians confirmed Dodge/Stellantis is aware of the defect but said no repair or software update currently exists. The issue has been reproduced and documented. Based on symptoms and dealer feedback, this is likely a BCM or instrument cluster communication fault within the vehicle’s CAN network, affecting ignition, lighting, and safety indicator functions. It directly violates FMVSS 101 (controls and displays) and poses a serious road-safety risk. I request a full NHTSA investigation and recall for this defect, as it affects multiple Ram 1500 models and leaves drivers unaware of critical system failures.
