In software development that’s usually very easy to control. If that happens it’s not just incompetence, probably negligence.
Regressions from intentional changes though….good luck. No matter the size and term of the various beta groups you’ll hit cases. Hopefully not in most of your customer base but that’s the danger of frequent updates, much more likely.

Conversely Chrysler engineers don’t have to worry about pushing a button and breaking every car. Cars are moving from industrial class to consumer and the ride is interesting.
