Waymo is recalling about 3,800 robotaxis in the U.S. to fix software issues that could allow them to “drive onto a flooded roadway,” according to a letter on the National Highway Traffic Safety Administration’s website.
The voluntary recall is for Waymo vehicles that use the company’s fifth and sixth generation automated driving systems (or ADS), the U.S. auto safety regulator said in the letter posted Tuesday.
Waymo autonomous vehicles in Austin, Texas, were seen on camera driving onto a flooded street and stalling, requiring other drivers to navigate around them. It’s the latest example of a safety-related issue for the Alphabet-owned AV unit that’s rapidly bolstering its fleet of vehicles and entering new U.S. markets.
Waymo has drawn criticism for its vehicles failing to yield to school buses in Austin, and for the performance of its vehicles during widespread power outages in San Francisco in December, when robotaxis halted in traffic, causing gridlock.
The company said in a statement on Tuesday that it’s “identified an area of improvement regarding untraversable flooded lanes specific to higher-speed roadways,” and opted to file a “voluntary software recall” with the NHTSA.
“Waymo provides over half a million trips every week in some of the most challenging driving environments across the U.S., and safety is our primary priority,” the company said.
Waymo added that it’s working on “additional software safeguards” and has put “mitigations” in place, limiting where its robotaxis operate during extreme weather, so that they avoid “areas where flash flooding might occur” in periods of intense rain.

Semiconductor stocks fell sharply on Tuesday, reversing course after an extensive rally that had expanded the artificial intelligence investment theme well past Nvidia and driven the industry to unprecedented levels.

Qualcomm plunged 13% and was on track for its steepest single-day decline since 2020. Intel shed 8%, while On Semiconductor and Skyworks Solutions each lost more than 6%. The iShares Semiconductor ETF, which benchmarks the overall sector, fell 5%.

The sell-off came after a key gauge of consumer prices came in above forecasts, and as conflict in Iran pushed crude oil higher—prompting investors to shift away from riskier assets.

The preceding advance had widened the AI opportunity set beyond longtime industry leader Nvidia, which for much of the past several years had largely carried the market to new peaks on its own.

Explosive appetite for central processing units, along with the graphics processing units that power large language models, has sent chipmakers to all-time highs.

Market participants are wagering that the shift from AI model training to autonomous agents will lift demand for additional AI hardware. Among the beneficiaries are memory chip producers, which are raising prices as supply remains tight.

Micron Technology slid 6%, and Sandisk cratered 8%. Sandisk’s stock has surged more than six times over since January.

The Nasdaq will rise to 30,000 points in the next year as a bumper earnings season continues to bolster enthusiasm for AI stocks, Dan Ives, managing director at Wedbush Securities, told CNBC’s Squawk Box Europe on Monday.
A solid tech earnings season has seen investor jitters earlier this year replaced with bullishness over the AI infrastructure buildout. At close on Friday the Nasdaq Composite ended at 26,247.08, marking a 12.93% increase so far this year.
“These earnings have validated the AI bullish thesis,” Ives said. “Demand and supply is 10-1 for chips. We are in the early days still of the AI revolution. The haters will hate, and we know that.”
Michael Burry of “Big Short” fame on Friday warned that the stock market’s fixation on AI is beginning to resemble the final stages of the dot-com bubble.
“Stocks are not up or down because of jobs or consumer sentiment,” Burry wrote. “They are going straight up because they have been going straight up. On a two letter thesis that everyone thinks they understand. … Feeling like the last months of the 1999-2000 bubble.”
But Ives is backing the AI rally to continue for another two years.
“It’s a memory super-cycle,” he said, referring to the unprecedented demand for memory chips sparked by a rapid AI infrastructure buildout. “When it comes to SK Hynix [and other memory companies] we’re very bullish in what we’re seeing there.”
“It’s about playing the hyperscalers — of course chips, then you have to play software, cybersecurity, infrastructure [and] power. You can’t just own one subsector, you have to own the derivative plays,” Ives said.
Over the past month, Nasdaq’s PHLX Semiconductor Sector Index — comprising the 30 largest U.S.-traded chip companies — has soared 38%. Intel, Nvidia, Apple and Alphabet have all enjoyed double-digit growth.
Paul Tudor Jones, founder and chief investment officer of Tudor Investment, also told CNBC’s “Squawk Box” on Thursday that the AI-fueled bull market still has further to run, but added there could be some “breathtaking” valuation corrections in time.
