Significant engine complaints include catastrophic internal component damage (pistons, lifters, rods, camshafts, bearings) leading to complete engine failure or sudden power loss. Some reports suggest failures occurring beyond typical warranty periods. Estimated repair cost: $3,000 - $8,000+.

Electrical System Failures

Complaints involve system shutdowns, infotainment (cue system) defects, and potential fire hazards originating from seatbelt harnesses. These issues can range from minor annoyances to critical safety concerns. Estimated repair cost: $500 - $2,500+.

Reports include failures of front struts, which can impact steering and overall vehicle control. While less critical than engine or electrical issues, suspension problems affect ride quality and safety. Estimated repair cost: $400 - $1,500.

Forward Collision Avoidance System Malfunction

Complaints mention issues with the automatic emergency braking system, potentially due to electrical defects or sensor problems. This can lead to unexpected system behavior or disablement. Estimated repair cost: $300 - $1,000.
