Your truck's blind zone alert system — which warns you about vehicles in your blind spots — stopped working multiple times and needed several repair attempts before the problem was fixed. The dealership found that a faulty wiring harness was causing the system to fail, creating a safety risk during lane changes. The repeated visits to diagnose and repair the issue resulted in significant out-of-pocket costs. Fixing this issue involves replacing the wiring harness that connects the blind zone alert system.

NHTSA #: 11726153
