Default Tail Gate Only Stays Open Above a Certain Temp

Kinda funny and strange, but why does my RX 300s tailgate only stay open above a certain ambient temperature? I believe when it gets below around 55F it simply won't stay open and closes on itself. Is the gas inside the hydraulics not expanding enough at those temps??

Really not a big issue since I live in Arizona, but just curious (since it happens sometimes during winter time).

Replace struts. They are very cheap and easy to. Or, tailgate will drop on your head one of them AZ cold nights.

Very common problem, very easy fix. Replace struts.

I also noticed on your first post TechyInAz that you have the other universal RX300 problems: drooping visors and failed door lock actuators.

Drooping visors are a cheap & easy fix: put neodymium magnets between the visor and the ceiling. I used these. I think I needed four on each visor so I had to buy a couple packs to do both side with extras left over. I tried the other fixes to try to restore proper operation first but they failed miserably so don't bother. Just get the magnets.

Door lock actuators are a cheap fix but they take some effort. It is totally worth it though! Go here and don't be intimidated because it really is not as hard as it sounds. I paid $300 to the dealer to fix the first door, and $5 for a motor to fix the second one, and $17 for an
actuator actuator
to fix the third. I'm expecting the actuator will be a lot easier than the motor.

Good luck,
Owen

thank you everyone! I'll definitely replace the struts by this winter if i have time.

owen, going back to my door actuator problem, so how do i know if it's an actuator or a motor problem? When i press the door lock button, the door locks make their normal loud clicking noise, but they don't fully flip into either the closed or open position. I'm assuming all 4 locks have an actuator problem.

I live in Georgia. Same issue. The others who have responded are correct. New lift assists fixed it for me TWICE, four years ago and today. "Stabilus" brand lift supports from Rockauto.com is where I got mine. Perfect fit. The gate went up slower than it had before and pushing the switch to lower it did the job nicely in 92 degree weather.
