While driving, the instrument cluster/odometer intermittently flashed and became difficult to read for ~15 minutes. After parking, the odometer continued flashing for ~10 additional minutes. After the flashing stopped, the vehicle displayed “ParkSense Unavailable – Service Required.” On a separate date, with no trailer connected and without pressing steering wheel buttons, the cluster displayed a “Blind Spot Alert – Trailer Type (Conventional/Goose/5th) – Press OK to Select” prompt. These events were captured on video. Safety risk: driver information/warnings become unreliable while the vehicle is in motion, which is distracting and may reduce awareness of speed/vehicle status. No crash, injury, or fire occurred. A dealer inspected the vehicle and reviewed the customer video. The dealer documented stored electrical/communication/configuration faults consistent with the concern, including ECU configuration mismatch, lost communication with the trailer interface module, and communication bus off faults. The dealer performed software updates to related modules and road tested ~34 miles; the concern did not reproduce during the test drive. The vehicle also has an open safety recall (NHTSA 26V-059 / FCA 03D) for the trailer tow module with remedy/parts pending. Incidents occurred on 02/16/2026 and 02/18/2026 at ~3,000 miles, including after cold/rain conditions. One restart sequence did not immediately stop the flashing. Dealer scan recorded the following (stored) DTCs: TIPM B2204-87 (ECU configuration mismatch), TIPM U116B-00 (lost communication with trailer interface module), and ITCM U0077-00 (communication bus off). Dealer performed module software updates including CADM update per TSB 08-020-26 and PCM update per RRT-26-036. Recall remedy for 26V-059 / FCA 03D remains pending parts.

How to use these: a complaint is one owner’s report, filed voluntarily and published unverified. Patterns matter more than any single story. If several owners describe the same failure at similar mileage, put that system at the top of your pre-purchase inspection list. Back to the full 2026 Ram 3500 verdict →
