Electrical System Malfunctions

Complaints include autonomous window operation, engine auto-stop failures, and complete vehicle stalling. These issues can stem from faulty control modules, wiring harness problems, or sensor failures. Estimated repair cost: $200 - $1,500+.

Engine Performance Concerns

Issues include overheating warnings and catalytic converter problems. Overheating can be due to coolant leaks or thermostat failure, while catalytic converter issues often point to underlying engine combustion problems. Estimated repair cost: $300 - $2,000+.

Steering System Vulnerability

A recall addressed potential loss of power steering due to corroded Electronic Power Steering (EPS) connectors. While the recall remedy exists, ongoing vigilance for steering feel changes is prudent. Estimated repair cost: $500 - $1,200.

Suspension Components

Complaints include issues potentially related to suspension toe-links and general wear. Early failures at lower mileages suggest potential durability concerns beyond normal wear and tear. Estimated repair cost: $300 - $1,000.
