Parts for your 2012 Mazda Cx-5-Gas struts

2012 Mazda CX-5 gas struts – what they do and when to replace them

Gas struts are absolutely relevant to the 2012 Mazda CX-5. Technical sources including the Mazda CX-5 (KE series, 2012) workshop manual (Body – Liftgate section) and Mazda’s electronic parts catalogue list the rear liftgate “stay damper” assemblies, which are nitrogen-charged gas struts. From factory the CX-5’s tailgate uses a pair of gas struts, the bonnet is typically supported by a prop rod rather than gas struts on this model.

On the CX-5, the gas struts do the heavy lifting for the rear hatch, making it easy to raise and holding it safely open. They’re sealed units that use compressed gas and a small amount of oil to provide smooth, controlled movement. When they’re healthy, the tailgate glides up without fuss and stays put, even on a breezy day at the beach or a cold morning in Queenstown.

Over time, seals age and pressure drops, especially with temperature swings and high kilometres. As part of routine servicing, it’s smart to give the struts a quick check: make sure the hatch opens consistently, doesn’t sag, and that the chrome rod is clean and free of nicks. Keep silicone and solvents off the rod—just a gentle wipe with a clean, dry cloth is best. Don’t lubricate the rod, that can foul the internal seals.

• Tell-tale signs it’s time to replace:
  • Hatch falls or won’t stay fully open
  • Slow or jerky lift, worse in cold weather
  • Needing to “help” it up by hand
  • Oil mist or staining around the rod ends

Replacement is straightforward for a trained tech and should be done in pairs so the hatch lifts evenly. Always support the tailgate with a prop or a helper, wear eye protection, and avoid twisting the rod. New struts must match the correct length, end fittings, and force rating for the 2012 CX-5. Quality OEM or reputable aftermarket units are both fine, the key is correct spec and proper installation on clean ball studs with fresh clips.

Most owners can expect 5–8 years out of a set, depending on climate and use. A quick annual check during servicing helps catch weak struts early—no surprises, no bruised foreheads, and the tailgate works like a charm.

Do all 2012 CX-5s have gas struts?

Yes—for the rear liftgate. Technical Mazda documentation for the KE-series confirms liftgate stay dampers (gas struts) are factory-fitted. The bonnet on this year typically uses a prop rod, not gas struts.

Should gas struts be replaced in pairs?

Definitely. Replacing both keeps the lifting force balanced, prevents twisting the hinges, and restores that smooth, even rise the CX-5 is known for.

How long do CX-5 liftgate struts usually last?

Commonly 5–8 years, but harsh sun, salt air, frequent use, and cold snaps can shorten that. A quick yearly check during servicing helps spot a weak set before they let the hatch droop.
