Ok I see the issue, at the time the BBC article was written they hadn't paused service yet. That remedy you're referring to didn't work though, so now they have completely paused service in two cities.

> Waymo has now paused service in two cities because its robotaxis are struggling to deal with heavy rain and flooded roads, a problem that already prompted the company to issue a recall last week.

> Waymo admitted that it hadn’t finished developing a “final remedy” for avoiding flooded areas when it issued its software recall last week. Instead, the company said that it shipped an update to its fleet that placed “restrictions at times and in locations where there is an elevated risk of encountering a flooded, higher-speed roadway,” according to documents released by the National Highway Traffic Safety Administration (NHTSA).

> But even those precautions apparently were not enough to stop the Waymo robotaxi from entering the flooded intersection in Atlanta. Waymo told TechCrunch on Thursday that the storm in Atlanta produced so much rainfall that flooding was happening before the National Weather Service had issued a flash flood warning, watch, or advisory. The company said those alerts are part of a larger set of signals it relies on to prepare the vehicles for poor weather.

I still think the BBC headline is fine, but I guess if you aren't familiar with this usage of "recall" then you could be misled.
