What to look for: Watch for a red battery light or 'electrical fault' message, especially while driving.
Why it matters: This fault has been reported to cause a complete loss of power steering and brake assist while driving, which is a serious safety risk, not just an inconvenience, and parts have reportedly been on back-order for extended periods.
What to look for: Check all corners sit level before starting and after standing, then cycle access and off-road heights.
Why it matters: Front struts and rear dampers are common replacements on this generation once a car reaches high kilometres, so a corner that drops overnight is a fairly predictable repair cost rather than an unusual fault.
What to look for: Ask for a receipt that names both the front timing belt and the rear fuel pump belt, with date and kilometres.
Why it matters: Because the rear belt is harder to reach, it is reported to sometimes be skipped by garages doing only the obvious front belt, so a receipt naming only one belt does not confirm the job was done properly - a snapped belt on either side wrecks the engine.

What to look for: Check the coolant level cold and look with a torch around the front and rear thermostat housing for pink crust.
Why it matters: This fault has led to a fuel line rupture in at least one documented case after rapid overheating, so it is a safety issue as well as a mechanical one, and owners on specialist forums now fit aluminium replacement pipes pre-emptively rather than wait for a failure.
