Yes, it is not rare.
The text description and the page on the displayed link clearly describes the situation:
it is recommended to verify data and power cables, connections - and if possible try different cables to prevent further problems.

As you can see, new and new communication issues detected because of incorrect connection / cable, which can result in damaged files and even unbootable system.
The MOST IMPORTANT in this case suggested by the software: verify connections and cables and try to replace data cable to stabilize the problems first, to make sure that the error counter should not increase further. Current problems will remain displayed - but the most important is that you should not see further increase at attribute #199.
If you continue using the disk while the status is not stable (while the error counter is still increasing) then you risk further data corruption, further damage of the file system and even data loss. Chkdsk is absolutely not recommended in this case. As it attempts to "fix" the file system (not the SSD of course, just the logical volume) it can cause even more problems and damage more files because it may also incorrectly read and "repair" the file system descriptors (which may be more damaged, resulting more data loss).
> Is this definitely indicating the the SSD drive is failing ?
Such issues are usually independent from the SSD but more related to the cables, connections or something else which can cause unstable operation (see the recommended page for details, it can be overclock, generic overheat etc.)
You'd need to make sure that the error counter should NOT increase further by checking connections, replacing cables first.
Then you can perform diagnostics, to reveal any possible issues OR confirm if the status is stable by using the tests under the Disk menu.
For example, the Disk menu -> Surface test -> Read test is a good way to perform a complete, safe scan to verify if the complete SSD is readable, there are no problems. If the error counter does not increase during that (so the status is now stable), THEN you can perform chkdsk to repair the partition (if required). But starting chkdsk sooner while the error counter is still increasing lead to bigger problems.
The SSD health because of #177 is slowly but surely decreasing due to the writes. But it is normal for most SSDs, so until the health is generally high (eg. 50% or above) you do not need to worry about it.
