It is not a uncommon condition as you were informed, but several checks need to be performed prior to replacement/repair of cluster. You will need to inspect both fuse that supply cluster with power. They are located in the fuse box underhood and depending on what option vehicle has check the IPC/DIC FUSE or EO B1 fuse. This supplies constant battery voltage to cluster. The next fuse listed will supply ignition on power - IGN E . If the cluster does work at times and there are other electrical issues happening at the same time like intermittent no start or crank, turn signal problems, you will need to test for low voltage on IGN E circuit. If you verify this condition, ignition switch will need replacement. If no other condition you are on the correct path.
