2016 Honda Odyssey gas struts: what they do and when to replace them

Based on technical references — including the Honda Service Manual (2011–2017 Odyssey, Body—Tailgate) and the Honda Electronic Parts Catalogue for the 2016 model year — the 2016 Honda Odyssey is fitted with twin gas‑charged lift supports on the rear tailgate. These assist the liftgate to open smoothly and stay up safely, including on power‑tailgate variants which still rely on gas struts for balance. The bonnet on this model uses a manual prop rod, not gas struts.

On a 2016 Odyssey, gas struts take the grunt out of lifting the tailgate and keep it steady overhead. They’re nitrogen‑charged dampers with a small amount of oil inside, designed to provide controlled assistance so the tailgate doesn’t drop or slam. Over time, seals age and the gas charge bleeds off, especially in colder climates, and the tailgate can start sagging or feel heavy. That’s the cue for service or replacement.

As part of routine servicing, it’s smart to check tailgate operation: does it rise smoothly, hold at full height, and resist drifting down in a breeze? If not, new struts are due. Visual checks help too — a light oil film on the shaft, nicked chrome, or rusty fittings are all red flags. There’s no effective or safe way to “re‑gas” automotive lift supports, replacement is the fix.

Replacement is straightforward for a trained tech and should be done in pairs so the opening force stays balanced. The tailgate must be securely supported during the job (a prop or second person is essential). Clips are released, old struts come off, new ones click on, and mount hardware is tightened to spec. After fitting, the tailgate height and power‑tailgate operation (if equipped) should be checked to ensure smooth, even movement.

To get the most life from new struts, keep the shiny piston rods clean and free of grease or silicone sprays — contamination can damage the seals. Expect lifespan to vary with use and climate, vehicles parked outside or used frequently may need struts sooner. If the Odyssey’s tailgate starts needing a hand to stay up, replacing the gas struts restores safety and that easy, one‑handed convenience owners expect.

• Common signs they’re due: tailgate drops or won’t hold, slow or jerky opening, worse performance in cold weather, oily residue on the rod.
• Always replace in pairs and support the tailgate during service.

Popular questions about 2016 Honda Odyssey gas struts

Do 2016 Odyssey bonnets use gas struts?
No. The bonnet uses a manual prop rod. Gas struts are fitted to the rear tailgate only, including models with a power tailgate where they work alongside the motor to balance the lift.

How long do Odyssey tailgate struts usually last?
It depends on climate and use, but many last several years before losing pressure. If the tailgate sags, won’t hold at full height, or struggles in cold weather, it’s time to replace them.

Can just one gas strut be replaced?
It’s not recommended. Replacing in pairs keeps lift and hold forces even, protects the hinges and power mechanism (if fitted), and delivers the best, most consistent tailgate operation.
