The vehicle horns worked intermittently during the first year, but don't work at all now. When the alarm operates, the lights will flash, but there is no sound from the horns. Based on feedback from owners' forums, there is an issue with the horn relay surface-mounted to the underhood fuse panel. This requires replacement of the fuse panel. Not having an operational horn is a safety issue for other motorists and me, as well as wildlife.

The vehicle experienced significant vibration at highway speeds and during braking within the first 6 months of ownership. The issue was confirmed by a dealership, and the rotors were resurfaced as a corrective action. The problem has now returned, and the rear brakes have worn down to metal-on-metal at approximately 35,000 miles. The rear brake pads are also unevenly worn, while the front brake pads remain in good condition. Multiple service representatives have stated they cannot explain this level of uneven rear brake wear. The brake defect causes strong vibration that impacts steering control and vehicle stability, especially at highway speeds and while slowing down. This creates a safety concern due to reduced braking performance and loss of consistent vehicle control. The issue has been confirmed by dealerships, but the root cause has not been identified or properly resolved. No warning lights or alerts were provided prior to the failure. The vehicle is currently unsafe to drive due to the condition of the brakes.
