On 10/21/2024 the main gauge cluster began flickering and lasted that way for several days while GM had part on back order. Then on 11/9/2024 the gauge cluster went completely out while driving at night with no indication of speed or status. The incident was very disorienting but did not cause an incident. GM has been waiting on the part since 10/28/2024 with the latest delivery expected in Feb 2025. Each month the part’s expected arrival slips several weeks, and our confidence is low that the part will be available in Feb.
