The inside and outside door handles are prone to breaking.

Power brake systems using "hydro-boost" may leak power steering fluid from the hydro-boost unit located behind the brake master cylinder. Replacement of the hydro-boost unit is the common repair to correct this concern.

The power door lock actuators may become slow to operate or stop working completely and require replacement.
