Some TSX owners complain about a dash light failure. The issue appears to be most common on 2004 models. Repairing this can be troublesome, as, depending on the issue, removal of the instrument cluster will be required. In more severe cases, it's an issue of the wiring and board setup powering the cluster, that can require repairs.
