2015 Toyota Vitz / Yaris gas struts – what they do and when to replace them

Yes, the 2015 Toyota Vitz/Yaris hatch uses gas struts on the rear hatch (back door). The bonnet is held up by a manual prop rod, and the Yaris sedan’s boot typically uses torsion bars rather than gas struts. This fitment is confirmed by Toyota’s body repair information for the back door damper, Toyota’s Electronic Parts Catalogue (P13# Vitz/Yaris listing for “Back Door Stay/Lift Support”), and common aftermarket fitment catalogues for 2011–2017 Yaris hatch models. So, for hatch owners, gas struts are very much relevant.

On the Yaris hatch, gas struts support and control the rear hatch as it opens and closes. They’re small, pressurised dampers that counterbalance the hatch weight, preventing it from dropping on someone’s head and making it easy to lift with one hand. Good struts lift smoothly, hold the hatch at full height, and close without a fight.

Like any wear item, they get tired over time—especially with heat, dust, and frequent use. Typical signs it’s time to replace them include:

• Hatch won’t stay up, or sags in wind or cold mornings
• Needing two hands or an extra shove to open
• Oily film or dampness on the rod, or obvious hissing/leaks
• Uneven lifting or clunks at the ball/socket ends

As part of routine servicing, it’s smart to check the hatch action and the strut rods. Keep the chrome rods clean and dry—don’t grease the rods, as grease attracts grit and can damage the seals. If one strut is weak, replace both together to keep lift and latch alignment even. During replacement, support the hatch securely with a prop or a helper, swap one side at a time, and inspect the ball studs and brackets for play or corrosion. Choose quality, vehicle-specific gas struts with the correct force rating for the 2015 Vitz/Yaris hatch, over-strong units can stress hinges, and under-strength units won’t hold properly. In most cases, replacement takes 10–20 minutes with basic tools and no special adjustments. With fresh struts fitted, the hatch should rise smoothly and stay put at full height—safe, simple, and hassle-free for daily use.

Popular questions about 2015 Toyota Vitz/Yaris gas struts

Do all 2015 Yaris models have gas struts?
The hatch does on the rear hatch. The bonnet uses a prop rod. The Yaris sedan (where offered) generally uses torsion bars for the boot lid rather than gas struts.

How long do the hatch gas struts last?
Often 5–8 years, but climate and usage matter. If the hatch sags, needs a shove to open, or shows oil on the rods, they’re due. Replace in pairs for even lift and proper latch alignment.

Can one replace just one gas strut?
It’s not recommended. A new strut paired with a worn one can twist the hatch and stress hinges. Replacing both together restores balanced lift and consistent holding force.
