Typical electrical symptoms owners report
- Owners report the entire electrical system briefly "blacks out" while driving — dashboard, lights, and radio go dark for a few seconds, then reset on their own with no warning.
- Some describe the shutdown happening at night, leaving headlights, taillights, and interior lights off for a few seconds on dark roads.
- Several report the automatic high-beam camera system staying enabled even when the camera view is blocked, keeping the indicator light green incorrectly.
- One owner reported the speedometer reading incorrectly, which the dealer attributed to a glitching navigation system feeding speed data instead of a vehicle speed sensor.
- One owner described an unresolved Electronic Stability Control (ESC) steering malfunction that persisted after a dealer re-diagnosis.
- Other owners report the horn becoming inoperable and HVAC controls (A/C and vent mode) failing to hold selected settings.
