2014 Mazda Premacy (Mazda5) Gas Struts — What They Do and When to Replace Them

Technical sources confirm the 2014 Mazda Premacy (Mazda5, CW series) uses gas-charged struts on the rear liftgate. The Mazda workshop manual for the CW platform identifies the “liftgate stay damper” as a gas-filled support, and this is reflected in Mazda’s electronic parts catalogue and common aftermarket catalogues (e.g., Stabilus/Monroe) listing rear hatch lift supports for 2010–2015 Premacy/Mazda5. The bonnet on this model uses a prop rod, not gas struts.

On this people-mover, the gas struts take the grunt out of lifting the tailgate and hold it up safely while loading. Over time, the sealed nitrogen charge and internal oil can fade, especially with heat, cold, and frequent use. If the hatch feels heavy, won’t stay up, drops suddenly, or the strut rods show an oily film or pitting, it’s time to replace them.

Best practice is to replace gas struts as a pair to keep lift and hold balanced. It’s a straightforward job: support the tailgate securely with a prop or helper, flick back the retaining clips at each end with a small flat screwdriver, pop the old struts off the ball studs, then press the new ones on until they click. No need to remove the clips fully. Avoid twisting the body, and never clamp the chrome rod.

Service tips for the Premacy’s hatch struts:

• Check operation at each service or 12 months: smooth lift, firm hold at full extension, no creaks or dead spots.
• Keep the rod clean and dry, don’t grease or spray silicone on the rod—lubricants attract grit and damage seals.
• Cold mornings will reduce lift slightly, noticeable seasonal sag suggests the gas charge is weak.
• Use only struts with the correct force rating and end fittings for the CW Premacy/Mazda5 to avoid overloading hinges and glass.

Quality replacements generally last 5–8 years depending on climate and usage. If the vehicle has power sliding doors, they rely on tracks, rollers and motors rather than gas struts, so issues there are unrelated. For the bonnet, a tidy upgrade to gas struts is possible via aftermarket kits, but it’s not factory on this model year.

FAQs

How long do the tailgate gas struts last on a 2014 Mazda Premacy?

Typically 5–8 years in normal Kiwi and Aussie conditions. High heat, dust, and frequent opening shorten lifespan. If the hatch doesn’t stay up reliably, plan a pair replacement.

Can just one gas strut be replaced?

It’s not recommended. A single new strut will fight a tired mate, causing uneven loading and a hatch that lifts awkwardly. Replacing both keeps lift and hold consistent and protects hinges.

Do the bonnet or sliding doors use gas struts on this model?

The bonnet uses a prop rod from factory, not gas struts. The sliding doors use tracks, rollers, cables and (if equipped) power actuators—no gas struts there. Only the rear liftgate uses gas struts as standard.
