Known Issues
|
|
Turbo Wear:
|
Turbocharger seals and bearings can wear over time, leading to oil consumption and reduced boost. Proper warm-up and cool-down procedures are crucial.
|
|
Suspension Bushings:
|
Worn suspension bushings are common due to age and mileage, leading to clunking noises and degraded handling.
|
|
Rust And Corrosion:
|
Prone to rust, especially around wheel wells, rocker panels, and subframes, due to age and exposure.
|
|
Cv Joints:
|
Outer CV joints can wear, producing clicking noises during turns, especially on AWD models.
|
|
Oil Leaks:
|
Valve cover gaskets, oil pan gaskets, and front/rear main seals can develop leaks over time.
