|
Electrical System Issues:
|
Can be complex; issues with window regulators, central locking, ABS sensors, and wiring harness connectors are not uncommon.
|
Suspension Wear:
|
Front suspension components (wishbone bushes, ball joints) can wear due to the sporty setup.
|
Rust:
|
Areas prone to rust include wheel arches, sills, and the rear subframe, particularly in regions with harsh winters.
