I first saw it when trying to fiddle with PCP bits on inner tags.  The commands existed in the CLI to do it, but the SDK said no when I tried to commit.

VLAN ranges also failed miserably - there was one instance where it worked, but if you had double tagged traffic then it was a no-go (even if the range was just on the outer tags).

There were a bunch of other cases too that escape me.  Our Cisco rep basically said "yeah, they rush to get the new boxes to market and don't get time to clean up the CLI & docs".  Thanks Cisco.

We have a handful of those in my current job - fortunately I have nothing to do with them, but I have heard of PSU's failing.

Lack of knowledge is another factor.  "Please reseat the line card".  "It's a fixed chassis, should I use a cold chisel or an angle grinder?".  "Download this IOS" - but that's XE, and this is an XR box...

....and the old "meet the response SLA by asking the customer questions, for the 2nd, 3rd, or 4th time, that they provided the answers to in the original case creation".
