Purchased vehicle new June 23 2023 and super cruise never worked and if engaged acted erratically . Vehicle spent over 40 days in several gm dealerships for the issue and one dealer even charged me for installing a warranty part. . Gm filled a case 9-10220813020 but were not helpful in dealing with dealers and to add insult to injury would not even reimburse me for warranty work or in any way compensate me for my time and efforts to fix the issue. Frustrated with gms indifference I traded the vehicle in March 2024.
