Waymo, the self-driving taxi company, has issued a recall covering thousands of its robotaxis to fix a software problem tied to highway construction zones, according to reporting from Wired, CNBC, and a report carried via MSN.

The core issue: some of the autonomous vehicles drove into closed freeway construction zones. According to Wired, the cars either prioritized other hazards or, in some cases, failed to recognize closed construction zones altogether. According to Wired, the recall covers 3,871 vehicles, while CNBC describes it as about 3,900 and MSN reports nearly 4,000.

The scale of the problem appears limited but real. The MSN report says at least 13 incidents were reported in connection with the flaw.

Importantly, this is a software recall rather than a physical defect. According to CNBC, Waymo implemented a voluntary recall, filed with U.S. regulator NHTSA, to fix the underlying software issues. In the world of autonomous vehicles, a "recall" often means an over-the-air software update rather than bringing cars into a shop.

CNBC notes this is the company's latest such action, and Wired similarly frames it as Waymo's latest recall.

Why it matters: As robotaxis carry more passengers on public roads, incidents like driving into closed construction zones test whether self-driving systems can reliably handle the messy, changing conditions that human drivers navigate every day — and how quickly companies and regulators catch and correct those gaps.
