Power Rear Door Opening Malfunction
#16
Yes, I was determined to figure it out! When I woke up this morning I thought about the possibility of an incorrect installation. I thought I was careful when I originally installed them but apparently that was not the case. Very happy now that everything is working as it should - can't beat that for $45 and less than an hour's worth of effort!

Well, the struts do not function at low outside temperatures. The door opens fine and stays open if the car is in the heated garage, is sitting in the sun, or the outside temperatures are above around 60 degrees Fahrenheit. If Charles Law explains this, then the maintenance people at Lexus need to read this and send out an advisory. I am done replacing struts; they work fine at the Lexus dealer because it is in a heated environment in the service area. As soon as I get them home, they fail when the temperatures cool.

Gas charged struts lose SOME of their function in colder temperature. I just replaced hood struts on wife's RX350 at only 54 000 miles as they won't hold hood up, unless pumped few times. It happened to be exactly when temperatures fell down to freezing. As you have sensor on tale gate, small strut function loss will trip sensor as now motor has to fight against "heavier" gate. I feel, they clearly under powered struts for rather very heavy hood and tailgate.

I have the same problem with my RX 400h 2006 in Greece with temperatures about 30 degrees Celsius. When I try to open the power back door either with remote key or with the button inside the car the result is that the tries to open for about 2 or 3 centimeters and then closes again. All other operations of the door work excellent. I put lithium grease on the struts (spray) but no result. The condition of the struts is excellent. Is there any idea (something like resetting/initialize the door) ?

Strange ghost in the machine
It sounds to me like the "pinch sensor" is being tripped. That is what stops the door from opening or closing if it feels too much resistance. This causes the door to immediately change direction to avoid crushing someone, or wacking the roof of your garage. As far as I know, there is no setting that would cause this to happen. It is strange that it works fine on the second attempt. I would def have the dealer take a look.
