Thankfully, an over-the-air software update will resolve the issue for affected vehicles.
Regenerative braking is a vital technology for EVs and PHEVs. Without it, they’d have a significantly lower range. The entire driving experience would be different since it enables B-mode and one-pedal driving. Now, 11,469 Volvo owners are finding out what that’s like to live with. The automaker just issued a warning to stop driving with either of those modes until it sorts out a braking issue.
The new recall, number 25V392000, includes several models from 2020-2026, including the S60, V60, S90, XC60, XC90, XC40, EX40, EC40, and C40. Those running software 3.5.14 might have issues with their brake control module. Specifically, they might experience a loss of braking functionality. While that sounds bad, there are two sides to this story.

According to Volvo, the issue seems to only pop up after “coasting downhill for at least 1 minute and 40 seconds.” It would be rare to do that on the vast majority of roads. One would likely be descending a mountain or dropping into a valley on a long highway.
But the big issue is what happens if it does occur. The automaker warns, “If the situation occurs, pressing the brake pedal may remove braking functionality entirely.” Clearly, that’s about the worst possible scenario.
Notably, Volvo didn’t provide a chronology report to explain how it heard about this situation, what it did in the aftermath, and how it decided to conduct a recall. Because of that, we’re missing a lot of vital information about how this all came about.
The NHTSA does require Volvo to produce that report, but it simply isn’t available yet. We do know that Volvo plans to fix all of these cars via a software update over the air. It’ll notify owners by August 6, and dealers already know about the situation.
Interestingly, this recall might actually be a bit bigger than 11,469 units. In a different piece of paperwork filed with the NHTSA, Volvo says that the recall includes 14,014 cars. We’ve reached out to the NHTSA to see why the figures are different. We’ll report back here if we learn the cause of that difference.
