Parts for your 2012 Honda Odyssey-Gas struts

2012 Honda Odyssey Gas Struts

Yes, gas struts are fitted to the 2012 Honda Odyssey. Honda’s factory service information for the 2011–2017 Odyssey platform identifies two gas-pressurised “tailgate stays” supporting the rear tailgate, and the Honda electronic parts catalogue (EPC) lists these as serviceable items for this model year. The bonnet on this generation uses a mechanical prop rod rather than gas struts, which is also shown in Honda’s service literature.

On a 2012 Odyssey, the rear gas struts do the heavy lifting—literally. They counterbalance the weight of the tailgate so it opens smoothly, stays up without drama, and closes in a controlled way. Even models with a power tailgate rely on these gas struts for the bulk of the support, the motor just assists. When they’re tired, the tailgate can sag, drop in cold weather, or the power tailgate may reverse or stop partway because the system senses too much load.

As part of routine servicing, it’s smart to give the gas struts a quick once-over. Look for oily residue around the shaft seals, bent rods, cracked end fittings, or loose mounting studs. Don’t lubricate the shiny rod—oil and grease attract grit that can chew up the seals. Just wipe the rod clean with a soft, dry cloth and keep the ball-joints and brackets snug and free of corrosion.

• Typical signs they’re due: tailgate doesn’t stay up, moves slowly or unevenly, needs a helping hand to open, or drops faster in cold weather.
• Safety tip: always support the tailgate before removing a strut. Replace in pairs to keep lift and balance even.
• Power tailgate note: weak struts can make the motor strain or cause auto-reversal. After replacement, follow the owner’s manual to reinitialise the power tailgate if required.

Replacement is straightforward with basic tools. Many will manage it at home in 20–40 minutes, but a technician can handle seized fasteners and verify correct alignment. Expect service life to vary with climate and usage, five to ten years is common. Using quality, vehicle-specific struts keeps the lift and close effort feeling factory-fresh, and helps the power mechanism (if fitted) live longer. Given the Odyssey’s tall, heavy tailgate, keeping those gas struts healthy isn’t just about convenience—it’s about safety for family and gear loading at the back.

Popular questions about 2012 Honda Odyssey gas struts

Do 2012 Odyssey bonnets use gas struts?
No—the bonnet uses a manual prop rod. Gas struts are used at the rear tailgate. This layout is noted in Honda’s service guides and parts listings for the 2011–2017 Odyssey.

How can someone tell the rear struts need replacing?
If the tailgate won’t stay up, drops faster than it used to, needs a shove to start moving, or the power tailgate slows, reverses, or beeps and stops, the gas struts are likely weak. Cold mornings often make failing struts show their true colours.

Can they be replaced at home or should a mechanic do it?
Most owners can replace them with basic tools and a helper to support the tailgate. On power tailgate models, follow the owner’s manual steps to reinitialise the system after fitting. If any mounts are corroded or you’re unsure, a workshop can sort it quickly.
