Purchased used 6/12/2026 at 188,882 miles from a franchised Chevrolet dealer. The integrated trailer brake system master fuse and passenger-side turn signal fuse were blown at delivery. When the fuses were replaced, the trailer brake system faulted and the failure disabled the ABS, traction control, and StabiliTrak (electronic stability control). Significant safety concern: with the master fuse blown/open, the vehicle displays NO warning messages of any kind — the safety-system failure is completely masked while trailer braking is inoperative. The warning cascade only appears when a good fuse is installed and the faulted circuit is energized. Separately, at approximately 12 days and ~1,700 …
