... it seems to wear out and need replaced every 3-4 months.
Has anyone had this issue and arrived at a solution which worked long term? Or, for a sanity check, are there other folks who are changing their charge lock more often than their brake fluid?
I replaced my charge socket lock (61136842870) about 4 months ago because it was getting stuck in the locked position on my home L2 charger.
The new one worked for a month or two then stopped locking. That's not an issue for home charging but I did want to address it to allow DC Fast Charging. I removed the "new" charge socket lock from the car and tried to manually turn the "emergency" arm to extend the locking pin to no avail. I was putting a decent amount of force on that arm and only held back because I didn't want to break it. Even trying to assist by "pulling" on the pin with pliers at the same time didn't work.
I tried jumping the lock with 12v across the outside pins and could tell there was a slight jerk, so the motor was trying to do something but no movement whatsoever. Even after opening up the mechanism, I couldn't get anything to move any of the gears inside in either direction. Finally, I removed gear #2 and then things started moving when I put 12v on the motor since it was only connected to gear #1 in the picture.
If I ran it like this for 10-30 seconds it would eventually stop and it seemed like gear #1 was binding in a way that was jamming the motor.
Long story short, I reinstalled my 'old' charge socket lock from the previous time (with the cap from the new one) and so far (3 lock/unlocks with the charge cable connected), it's working correctly. I just don't particularly want to have to do this again in 3-4 months. And more-so, I don't want to have to do it again in 6-8 months possibly in the freezing cold!
