2012 Holden Barina Gas Struts: What They Do, What’s Fitted, and When to Replace

Referencing the Holden Barina TM workshop/service information, GM Service Information (SI) for the 2012 Chevrolet Sonic/Aveo T300 platform, and common OE-equivalent catalogues (e.g., Stabilus Lift-O-Mat, Monroe/Max-Lift), gas struts are fitted to the 2012 Holden Barina hatchback to support the rear liftgate. The bonnet uses a manual prop rod rather than gas struts, and the Barina sedan’s boot typically relies on torsion bars rather than gas struts. So, for the TM hatch, gas struts are relevant, for the bonnet and many sedans, they’re not.

On the Barina hatch, gas struts make opening and holding the tailgate effortless. They’re sealed, pressurised dampers that counterbalance the weight of the hatch, slowing movement so it doesn’t slam and holding it safely at full extension. Over time, the internal gas charge and seals wear, reducing lift force.

Typical signs they’re fading include a tailgate that won’t stay up, drops suddenly in cold weather, or needs a firm shove to open. A quick driveway check is to open the hatch and see if it creeps down or bounces on the last bit of travel. Any drift or sudden drop is a cue for replacement.

For servicing the 2012 Barina hatch, most workshops recommend inspecting the tailgate struts every service interval or two (roughly 20,000–30,000 km), and replacing them in pairs when performance drops. Swapping them is straightforward with basic tools: safely prop the hatch, pop off the spring clips at the ball joints, change one strut at a time, and ensure the clips are fully seated. Because the units are sealed, there’s no topping up or greasing—just keep the rod clean and avoid nicking or bending it.

Quality OE-spec replacements restore that easy one-hand lift and steady hold at full height. It’s worth using matched left/right parts from a reputable brand and verifying the correct length and force for the TM hatch. Always support the hatch during the job, and never puncture or heat a gas strut—they’re pressurised.

• What’s fitted: Rear hatch gas struts (TM hatch), bonnet uses a prop rod, sedan boots generally use torsion bars.
• When to replace: If the hatch sags, won’t stay up, or is weak in colder temps—replace both sides together.

Popular questions

Does the 2012 Holden Barina have gas struts on the bonnet?
Not on the bonnet. The TM Barina uses a manual prop rod up front. The hatchback does have gas struts on the rear liftgate, while the sedan boot typically uses torsion bars.

How long do Barina hatch gas struts last?
Often 5–10 years, depending on climate and use. Cold weather usually reveals weak struts first. If the hatch won’t hold itself up or needs help to lift, it’s time for a new pair.

Can a handy owner replace the hatch struts at home?
Yes, with care. Prop the hatch safely, replace one strut at a time, and make sure the retaining clips are fully locked. If in doubt, a workshop can swap them quickly during a routine service.
