The voided rubber console bushes on the rear of the front lower wishbones are a notorious weakness on the PQ24 platform. Over UK road humps and potholes, the rubber splits and perishes rapidly, allowing excessive movement of the front control arms. This causes front-end knocking, steering vagueness under braking, and uneven front tyre wear, resulting in an immediate MOT failure. Many UK owners replace them with solid rubber bushes from the Audi A2 or Cupra models for long-term reliability.

The foam seal securing the metal ancillary carrier plate behind the interior door card perishes and shrinks over time. Rainwater running down the exterior door glass past the window scraper seal pools on top of the deteriorated carrier seal and drains directly over the inner door sill into the cabin footwells. Left unchecked, UK wet weather leaves carpets soaked, rotting the underlay, fogging windscreen glass, and occasionally damaging the convenience control unit located beneath the dashboard.
