NHTSA complaint #11697456, filed 2025-11, 75,000 miles“Display Instrument Center on the instrument cluster goes out for a couple of drive cycles and comes back on. I took it in to the dealer at the end of March and had the vehicle updated. There's a history with this issue with the Traverses and the Cadillac XT6. I don't know if it's a glitch when these parts were produced for GM or not but it needs to be investigated”

The gentleman also ran a test on the alternator and it came back with a failure on the voltage regulator but all others were good. I drove home hoping drive cycles would clear it out. I drove to work this morning getting the same errors and voltage not going above 12.0, dipping all the way to 11.5. …”
