Parts for your 2015 Mazda Cx-5-Gas struts

2015 Mazda CX-5 gas struts: what they do and when to replace them

Referencing the Mazda CX-5 (KE, 2012–2016) Workshop Manual (Body and Accessories – Liftgate), the Mazda Electronic Parts Catalogue for the KE series, and common aftermarket catalogues (e.g., Stabilus/Monroe listings), the 2015 Mazda CX-5 is factory-fitted with a pair of gas-charged struts on the rear liftgate. The bonnet is supported by a manual prop rod from factory, so bonnet gas struts aren’t OEM on this model.

On the CX-5, the rear liftgate gas struts do the heavy lifting, taking the weight of the tailgate so it pops up smoothly and stays put overhead. Each unit is a sealed, nitrogen-charged damper that delivers controlled lift and steady holding force without jolts, which makes day-to-day use safer and easier—especially with arms full of groceries or a pram.

Over time, seals can harden and the internal gas charge slowly fades. That’s when the tailgate starts feeling lazy, rises unevenly, or sags—worse on cold mornings. A faint oil film around the shaft, a hiss with little resistance, or the need to “help” the tailgate the last bit are all fair signs the struts are due.

• Typical lifespan: 5–8 years, shorter if the vehicle lives outdoors or the tailgate carries extra weight (e.g., add-on spoilers).
• Best practice: replace in pairs to keep lift and balance consistent.

Replacement is a straightforward DIY or quick workshop job—about 10–20 minutes a side. Support the tailgate with a prop or a helpful mate, then flick up the metal retaining clips with a small flat screwdriver and pull the old strut off the ball studs. Press the new strut on until it clicks, no need to pry the clip right off. Fit rod-end orientation to match the original (usually rod-down to protect the seal). Don’t twist the shaft and don’t lubricate it—oils and grease can damage the seal and attract grit.

As part of regular servicing on a 2015 Mazda CX-5, it’s smart to check the gas struts seasonally: wipe the shafts clean with a dry cloth, inspect the ball studs and brackets for play or corrosion, and test holding force with the car parked level. If the gate won’t hold fully open or droops in colder weather, plan a replacement before it becomes a safety risk. Genuine or quality aftermarket units both work well, match the specification to the KE-series CX-5 and avoid “heavy-duty” ratings unless the tailgate has extra weight added.

• How long do 2015 CX-5 liftgate gas struts last?
  Most owners see 5–8 years, but coastal exposure, frequent use, and cold climates can shorten that. If the gate won’t stay up or feels slow, treat that as your cue.
• Can they be changed at home?
  Yes—basic tools and a helper to hold the tailgate are enough. Swap them one side at a time, keep fingers clear of the clips, and don’t lube the shafts.
• Does the 2015 CX-5 have bonnet gas struts?
  No. Factory fitment is a bonnet prop rod. Bonnet struts are an aftermarket upgrade if desired.

Popular questions about 2015 Mazda CX-5 gas struts

How long do CX-5 liftgate gas struts typically last?
On a well-kept 2015 CX-5, expect around 5–8 years. Heat, salt air, and extra tailgate weight can bring that forward. If the gate drops, needs help to open, or slows right down in winter, they’re on the way out.

Can the gas struts be replaced at home, and what tools are needed?
Absolutely. A flat screwdriver to release the retaining clips and a prop or helper to hold the tailgate are the main requirements. Swap one strut at a time, align to the original orientation, and avoid lubricants on the shiny shaft.

Are bonnet gas struts fitted from factory on the 2015 CX-5?
No—Mazda used a bonnet prop rod on this model year. Bonnet strut kits are available aftermarket if a gas-assisted lift is preferred.
