In this month's Modern Railways magazine (August 2023), the New Train Reliability league table is published in Roger Ford's column, for Railway Period 1 2023-24. I believe in the normal world this means April 2023.
Of note is that the TfW 230s are not bottom of the league in terms of Miles per 701D. In fact, by that metric, they are currently doing slightly better than TfW's Class 231s (Stadler), and almost twice as well as Merseyrail's Class 777 (also Stadler). Both of which are brand new trains from the Swiss, famed for their supposed legendary reliability.
Miles per 701D is a measure of reliability and replaced 'MTIN' as the metric for measuring fleet performance in 2022, as explained here:

But the table quotes both 701D and MTIN figures. The article says that Miles per 701D, "....better reflects the impact of fleet failures on the fare-paying passenger."
In fact, in a paragraph accompanying the article, Roger Ford makes the observation:
"Appropriately, having described the trials and tribulations of TfW Rail's Vivarail Class 230 hybrid units, the five-strong fleet makes its debut in this month's New Train TIN-watch table. And, in relative terms, it's quite an impressive first showing, now only above the 2000 MTIN MAA mark, but with clear blue water between the fleet and Stadler's debutants at TfW Rail and Merseyrail. And also better than TfW Rail's longer-established CAF Class 197 DMUs. Of course, new fleets can flatter to deceive before the cold rolling averages take their toll. But, for the moment, chapeau to all those at Vivarail and TfW who, despite the turmoil, have finally got the trains into service, and six places off the bottom of the table to boot."
The statistics therefore suggest that performance is not as bad, relative to other much newer train fleets, as the naysayers, haters and gap year experts in this thread would have you believe.
Here is the table:
