Forward Collision Avoidance (FCA) System Malfunctions

Owners report 'phantom braking' events and unexpected automatic emergency braking (AEB) activations, often while adaptive cruise control (ACC) or Autopilot is engaged. These incidents can pose a significant risk of rear-end collisions. Estimated repair cost: $150 - $1,000+.

Electrical System Failures

Complaints include instrument cluster blanking, infotainment system failures, and other general electrical gremlins. These can range from minor annoyances to significant disruptions in vehicle operation. Estimated repair cost: $200 - $1,500+.

Tire and Suspension Failures

Reports indicate premature tire wear, including tread separation and sidewall damage, and suspension component failures (e.g., control arms) occurring at relatively low mileages. This suggests potential durability concerns for these components. Estimated repair cost: $500 - $2,000+.
