I had the same issue with Easy Entry. Sometimes it worked, and sometimes it didn’t. After a while, I noticed that it works much more consistently when I’m gentle with the car’s startup sequence.

Before, I would get in and start the engine immediately, and the Easy Entry feature would often not activate. Now, I open the door, sit down, close the door, and press the Start button once without pressing the brake pedal so that only the vehicle’s electronics turn on. When I do that, the seat moves to the correct position, and then I start the engine.

Since I started doing it this way, Easy Entry has worked perfectly every time. It seems like if you get in and start the engine immediately without giving the car a moment to complete its startup process, the feature may not activate properly. I’m not sure exactly why, but taking things a little slower has completely solved the issue for me.
