2
Suspension & Steeringmoderate~60,000-100,000 mi

Front lower ball joints are a notorious weak point, often requiring replacement every 60-80k miles. Sway bar end links and bushings also wear prematurely, leading to clunking noises and degraded handling. Steering rack leaks can develop…

3
Engine Cooling & Accessoriesmoderate~80,000-120,000 mi
