My m25 connector also “looks fine” and has no perceptable play, but sure enough when I have disconnects (or endless waiting for auger messages) that don’t recover on their own a gentle push of the cord towards the module plug would get everything back going again (or 9/10 times just adjusting the module height manually moves it enough to reconnect lol) . Additionally the disconnects are happening only when the module height is being adjusted - again supporting it being movement of the module cable causing the issue. This loose connection seems to be responsible for front camera outages/lag, module disconnects, and motor overcurrent errors (at least some of them, I also do have some motor issue maybe similar to yours, but you hear differences in running sounds when those crop up).
I’m currently testing a grommet (it’s about a 65-70A shore hardness material) for supporting the cord and preventing it from tugging on/moving the connector:
Doing a test run now but so far so good.
