Third Brake Light Detachment

A recall campaign addressed the potential detachment of the third brake light due to loose fasteners. While the issue is low in frequency, detachment poses a significant hazard to following traffic. Estimated repair cost: $100 - $300.

The high-performance V8 engine generates significant heat, and cooling system components like hoses, radiators, and water pumps can degrade over time, leading to leaks and potential overheating. Estimated repair cost: $500 - $1500.

The twin-turbocharged V8 is a powerhouse, but turbochargers are complex and can be susceptible to wear, oil starvation, or boost leaks, especially with age and mileage. Estimated repair cost: $2000 - $4000.
