Hope this helps. If you Google "Workhorse Dash Cluster Recall" several sites pop up that claim they will repair it:
50402-C Actia Instrument Cluster
Workhorse Custom Chassis has decided that a non-compliance with Federal Motor Vehicle Safety Standards (FMVSS) 101 and 105, which relates to motor vehicle safety, exists in certain subject models with Actia Instrument cluster. The non-compliances involve incorrect software programmed into the cluster such that certain driver warnings required by Federal Motor Vehicle Safety Standards (FMVSS) are not displayed. Incorrect software may not have the ability to illuminate warning lamps indicating brake system failure codes. FMVSS require river warning when brake failure codes are set.
