What owners reported
Source: NHTSA complaint databaseOwners of the 2 model years this bulletin names have filed 474 complaints with NHTSA since 2015. 244 of them name Electrical System — the same broad component group this bulletin is filed under. NHTSA groups complaints coarsely, so that means the same area of the vehicle, not necessarily the same fault.
On the 2025 Ram 1500, the 27 owners who gave an odometer reading for Electrical System reported it at a median of 6,000 miles. That figure is one model year’s, not the whole range this bulletin covers — medians from different model years are not averaged.
While driving the driver instrument cluster screen went black. After approximately 10 seconds the theft alarm arm red light went red. Then the TPMS tire warning light lit. Then the instrument cluster screen went back to normal operation

Is the OTHERDOC_146 repair free?
A over-the-air update is usually paid by the manufacturer on the vehicles it names, within the terms and time limit the document sets; the dealer checks the VIN against the manufacturer’s list.
Which vehicles does OTHERDOC_146 cover?
