Turbocharger Failure:
Common on high-mileage GT models due to heat and potential oil starvation if not maintained properly. Requires careful oil changes and allowing turbo to cool down.
Head Gasket Failure:
Can occur on the 4G63T engine, especially if overheated or subjected to aggressive tuning.
Suspension Wear:
Bushings, ball joints, and tie rod ends can wear over time, leading to clunking noises and alignment issues.
Automatic Transmission Issues:
