2012 Toyota Vitz/Yaris Gas Struts — What They Do and When to Replace Them

Yes, gas struts are used on the 2012 Toyota Vitz/Yaris hatch. Technical references that confirm this include the Toyota Repair Manual procedures for “Back Door – Back Door Stay (Removal/Installation)” for the XP130 series, and Toyota’s Electronic Parts Catalog (Body Group) which lists the “Stay Assy, Back Door” gas spring for the rear hatch. The bonnet on most 2012 Vitz/Yaris models uses a prop rod, not gas struts, but the tailgate relies on a pair of gas-charged struts to lift and hold it safely.

On this model, the tailgate gas struts do the heavy lifting, counterbalancing the hatch so it opens smoothly and stays put without drooping. They’re sealed, nitrogen-charged dampers that also slow the last bit of travel so the hatch doesn’t slam. Over time, seals wear and pressure drops, which is why they can feel weak on cold mornings or start sagging unexpectedly.

As part of routine servicing, it’s smart to give the gas struts a quick once-over. Keep the shiny piston rods clean and dry, and don’t lubricate the rods themselves—oils and greases can damage the seals. A light silicone spritz on the ball sockets only is fine. If replacement’s needed, swap them in pairs to keep lift even, and always support the hatch with a prop or helper before you start. Orientation matters too—fit them the same way the originals were installed (typically rod-down) to keep internal lubrication right.

• Common signs they’re due: the hatch won’t stay up, drops suddenly, needs a shoulder nudge to open, feels worse in cold weather, or shows an oily film on the rod.
• Replacement is a quick job with basic tools: unclip the retaining springs at the ends, pop the strut off the ball studs, and click the new ones on. Check the ball studs for wear and tighten to spec if they were loosened.
• Choose OE or quality aftermarket units with corrosion-resistant rods and OE-spec seals. They’re inexpensive insurance against a head knock or damaged tailgate.

With fresh gas struts on a 2012 Vitz/Yaris, the hatch opens with a light touch and stays put—handy for loading the weekly shop or chucking in the pram without worrying about a droopy tailgate.

How long do the tailgate gas struts usually last?

On a 2012 Vitz/Yaris, many see 5–10 years depending on use, climate, and how often the hatch is operated. Coastal air and frequent opening can shorten life. If the hatch won’t hold itself up or struggles in the cold, they’re ready to replace.

Can the original gas struts be re-gassed, or should they be replaced?

They’re sealed units and generally aren’t serviceable. Re-gassing isn’t recommended for this application. Replacement with quality new struts is the reliable, cost-effective fix and only takes a few minutes per side.

Does the 2012 Vitz/Yaris have bonnet gas struts?

Most trims use a manual prop rod for the bonnet, not gas struts. The gas struts on this vehicle are fitted to the tailgate (rear hatch) only, as confirmed by Toyota service documentation and the parts catalog.
