Lexus Master Tech here,
The rear wing sticking is a known issue, and should be addressed shortly by a TSB. Until then, dealers are told to uninstall the wing, bring it to the rest position and re-initialized the system. Hopefully an updated part will be coming out soon.

Too funny that such an innocuous part can be problematic on high end sports cars. This was about the only problem I ever had on 4 different Porsche turbos between 2001 and 2011.
NotaDood, can you share the cause of the problem (mechanical, software for speed activation, or . . .)?

Yes, I've done what previous posters have tried to no avail. Mine doesn't even have the light go out at any point. Maybe I should try it at highway cruise speeds above 50 mph.

Wing Fix
Lexus is on it. The wings on virtually all of the RCFs will jam after 500 activations. Why? The current ECU triggers a test at that point, and most of the motors are over-torquing during the test and jamming.
Lexus will soon be issuing an ECU replacement for all of us. In the interim, your technician should be able to reset/initialize the motor for another 500 activations.

I was just at my dealer inspecting a new RC-F that I am interested in. Parked, the wing was up so I can only assume that this car is demonstrating the problem. Bummer.

There is an on/off switch on the dash is able to manually raise and lower the wing. In your case, the wing is probably switched in the on position by the dealer.

My wing was not enabled when I got the car, went to the dealer and in the config using the left button on the steering wheel I think it's system you can enable / disable the wing, after he turned it on it go stuck lol and the button did not do anything. I went into the system again and turned it off and on and now it works fine.
I would try that 1st as it can reset it.
Also if you have the button on when you enable the wing it stays up, I think the systems do not sync very well as if it's off in the dash "green button" and you enable it through the system it works fine, if you enable it on the dash and system it stays up even if I turn ot off in the dash.

Why would they replace the ECU when they could just flash it?

how about being nice to fellow members trying to help out? Most ECUs in your Lexus are not flashable... only few are. ECU for wing is likely very simple. They will just replace the part and thats it. In most cases when it comes to Lexus, they will replace the parts with new one to fix the issue.
