Subaru Crosstrek Rear Hatch Strut Pressure Loss
The rear liftgate struts on 2013-2022 Subaru Crosstreks frequently lose pressure, causing the heavy hatch to drop unexpectedly or fail to stay open.
Last updated: 2026-05-15
What goes wrong
The gas-charged dampers (struts) that support the rear gate weight lose their internal nitrogen charge or seal integrity. This results in the hatch falling under its own weight, which can cause head injuries to users or damage to cargo. On models with the Power Rear Gate, the motor may strain and beep or reverse direction because it senses too much resistance from the failing struts.
Symptoms to watch for
- Hatch feels significantly heavier to lift than usual.
- The liftgate slowly creeps down after being fully opened.
- Visible oily residue (hydraulic fluid) on the strut piston.
- Squeaking or groaning noises when opening the trunk.
- Hatch fails to stay open specifically in temperatures below 40°F (4°C).
Root cause
Premature seal failure in the gas-charged cylinders, often exacerbated by cold weather or internal fluid leakage, leading to a loss of internal pressure.
Buy time with these
- • Avoid leaving the hatch open for extended periods in freezing temperatures.
- • Clean the strut pistons regularly with a dry microfibre cloth to remove salt/road grit.
- • Wipe a light film of silicone lubricant on the seals periodically.
Permanent fix
- Replacement of both gas-charged cylinders with updated OEM part numbers or heavy-duty aftermarket equivalents.
