I have this controller error and IMU errors all over the place. The IMU won’t calibrate 2 months out of DJI extended warranty.
If you want some help, you'll need to read the "Flight Log Retrieval and Analysis Guide", and post your log file.

Wow, that looks like a major IMU failure at 223sec into the flight ... think we need the Mobile device DAT log for this, the one for this flight ends with FLY068.DAT. How to retrieve --> Mavic Flight Log Retrieval and Analysis Guide (read under section 3.)
Like anything mechanical, the IMU can fail; actually, sooner or later it will fail. Considering the extreme nature of the failure in your bird, it'll probably need to be replaced.Always babied this drone always did everything by the book why all of a sudden IMU failure? Do I need a new one or can the old one be reset?
I expect they'll say pretty much what I said, and set you up with a repair ticket, including a shipping label. I've had fast turnaround from them, and they have very reasonable repair pricing, so I wouldn't hesitate to get the repair done. As it stands, that drone isn't at all safe to fly.And what do you think DJI will say when I call them tomorrow?
Did this error cause it to climb to over 5000ft?Yes - very impressive data. Climbing at over 75 m/s to 1570 m AGL while spinning CCW at 130 rpm. I think the IMU needs more than a calibration.

Do some drones have redundant components for failures like this?
Could you explain "physically impossible". As 5000' is within the advertised range, I'm wondering what is the limiting factor for altitude. Is it built into the software and if so what is the altitude limit. ThanksIt didn't actually do that of course - it would be physically impossible. The IMU data are spurious.

Thank you Oz - so to clarify - the 500m is a limitation controlled by software in all models of DJI drones? And am I correct in assuming this is altitude above the take off point?Altitude limit on DJI drones 500m.
But it was also the other information, "climbing at over 75 m/s to 1570 m AGL while spinning CCW at 130 rpm", all adds up to incorrectly recorded data.

Mavic Pro and Mavic 2 have dual IMUs and can, in theory at least, switch to the backup IMU if the primary fails. I've seen quite a few IMU failures with those aircraft however, and the switch seldom seems to happen.
