    Tail-light leaking in a 2017 Holden Astra?

    Holden Holden Advice Holden Astra Holden Astra Advice Holden Astra 2017
    ...

    Is it likely the right-hand outer tail-light lens on my 2017 Holden Astra has a leak? A repairer has advised it is common for this model to eventually develop leaks in the tail lights causing rust inside. Is this true?

    A leak in the tail-light lens is a remarkably common problem in a lot of vehicles. It’s even more likely if the vehicle has previously been in a crash and the tail-lights replaced by cheap imported units. You’ll spot a leak like this by condensation that will form inside the lens on a warm day.

    Your mechanic is correct, too, if water gets into the light unit, it can then make it into the boot or hatchback area. From there, it will wet the carpet or boot-liner and potentially run down inside the rear quarter panel or the area where the spare tyre lives, where it will sit and start the process of rusting the car’s metal. If there’s a musty smell when you open the hatch, then you probably have a leak and it needs to be fixed pronto.
