I have an XPS 13 (the current Intel version, not the ARM version obviously) and they definitely have not. In fact, I've had the touchbar replaced 3 times and the whole computer replaced once because when the touchbar gets too hot, it starts "phantom pressing" the keys on it.
The replacement machine still has the issue, but it has a newer generation CPU which generally runs a bit less hot, so it's not as big an issue as it was on the previous machine.
