Introduction: Zoox’s Second Software Recall Shakes Autonomous Driving
The world of self-driving cars is buzzing with innovation, but it’s not without its bumps—literally. Zoox issues second software recall this month after San Francisco crash, sending ripples through the autonomous vehicle industry. On May 8, 2025, an unoccupied Zoox robotaxi was involved in a collision with an electric scooter rider in San Francisco, prompting Amazon’s self-driving unit to recall 270 vehicles. This marks Zoox’s second software recall in a month, following a similar issue after a Las Vegas crash in April. At Startup INDIAX, we’re diving deep into what went wrong, why these recalls are happening, and what they mean for Zoox’s quest to redefine ride-hailing. With competitors like Waymo and Tesla pushing the boundaries, Zoox’s latest stumble raises questions about safety, reliability, and the future of autonomous driving.
What Happened in the San Francisco Crash?
On a seemingly routine day in San Francisco, an unoccupied Zoox robotaxi was navigating a low-speed turn at an intersection when it was struck by an electric scooter rider. According to reports, the robotaxi had braked to yield to other road users, but the e-scooter collided with it, causing the rider to fall and sustain minor injuries. The rider declined medical attention, but the incident didn’t end there. After the collision, the Zoox vehicle resumed moving, completing its turn before stopping, without making further contact with the rider. This behavior—continuing to move after a crash—raised red flags about the vehicle’s ability to detect and respond to vulnerable road users like pedestrians or cyclists.
The incident, reported by Reuters and CNBC, led Zoox to issue a voluntary software recall for 270 robotaxis equipped with outdated Automated Driving Systems (ADS) software. The recall, submitted to the National Highway Traffic Safety Administration (NHTSA) on May 21, 2025, aims to improve how Zoox vehicles track nearby pedestrians and prevent movement when someone is close. At Startup INDIAX, we see this as a critical moment for Zoox to address safety gaps in its technology, especially in complex urban environments like San Francisco.
Why Zoox Issued the Second Software Recall
Zoox issues second software recall to fix a critical flaw in its ADS that could put pedestrians at risk. The San Francisco crash exposed a weakness in how the robotaxi’s software tracks nearby objects, particularly vulnerable road users like e-scooter riders. According to Zoox, the vehicle’s software failed to adequately prevent movement after the collision, which could have led to more serious consequences. The updated software, already deployed across the affected 270 vehicles, enhances pedestrian tracking and ensures the vehicle remains stationary when someone is in a vulnerable position nearby.
This isn’t the first time Zoox has faced software challenges. Just weeks earlier, on April 8, 2025, a Zoox robotaxi collided with a passenger car in Las Vegas, prompting another recall of 270 vehicles. That issue stemmed from the software’s inability to accurately predict the movement of other vehicles, increasing the risk of crashes. Both recalls highlight a recurring problem: Zoox’s ADS struggles to interpret the unpredictable nature of real-world traffic, whether it’s cars, scooters, or pedestrians. For a company aiming to launch commercial robotaxi services, these setbacks underscore the need for robust, fail-safe systems.
The Las Vegas Crash: A Pattern of Software Issues?
The San Francisco crash wasn’t an isolated incident. On April 8, 2025, an unoccupied Zoox robotaxi collided with a passenger vehicle in Las Vegas, resulting in minor damage but no injuries. The issue? A software defect that caused the robotaxi to misjudge the movement of the approaching car. Zoox paused its driverless testing for over a week, conducted a safety review, and issued a software recall to address the flaw. The NHTSA report noted that the robotaxi slowed and steered to avoid the car but couldn’t prevent the collision when the passenger vehicle stopped unexpectedly.
This pattern of software issues—first in Las Vegas, then in San Francisco—raises questions about Zoox’s readiness for large-scale autonomous operations. While the company has already deployed fixes, the back-to-back recalls suggest deeper challenges in perfecting the ADS. At Startup INDIAX, we believe these incidents highlight the complexity of autonomous driving, where split-second decisions can make or break safety. Zoox’s transparency in issuing voluntary recalls is commendable, but it also puts pressure on the company to prove its technology is reliable.
Zoox’s Autonomous Driving Journey Under Amazon
Amazon acquired Zoox in 2020 for over $1 billion, betting big on its vision for autonomous ride-hailing. Unlike traditional automakers, Zoox designs purpose-built robotaxis without steering wheels or pedals, aiming to create a seamless, driverless experience. Since the acquisition, Zoox has been testing its vehicles in cities like San Francisco, Las Vegas, Los Angeles, Seattle, Austin, and Miami. The company is also scaling up production with a new factory in California and plans to launch commercial services in Las Vegas and San Francisco later this year.
However, Zoox’s journey hasn’t been smooth. In 2024, the NHTSA investigated two crashes involving Zoox-equipped Toyota Highlanders that braked suddenly, causing rear-end collisions with motorcyclists. Those incidents led to a recall of 258 vehicles for unexpected braking issues. Now, with Zoox issuing its second software recall this month after San Francisco crash, the company faces mounting scrutiny. Amazon’s deep pockets give Zoox the resources to innovate, but can it overcome these technical hurdles to compete with industry leaders?
How Zoox Stacks Up Against Waymo and Tesla
The autonomous vehicle race is heating up, and Zoox is lagging behind competitors like Alphabet’s Waymo and Tesla. Waymo is already operating commercial, driverless ride-hailing services in Phoenix, San Francisco, Los Angeles, and Austin, with plans to expand to Atlanta. Its proven track record and extensive real-world testing give it a significant edge. Tesla, meanwhile, is promising to launch its long-delayed robotaxis in Austin in June 2025, with ambitions to expand to San Francisco, Los Angeles, and San Antonio.
Zoox’s focus on purpose-built robotaxis sets it apart, but its recent recalls highlight a gap in reliability. Waymo’s ability to navigate complex urban environments with fewer incidents suggests a more mature ADS, while Tesla’s bold promises (despite delays) keep it in the spotlight. For Zoox, the challenge is not just fixing software bugs but building public trust in a technology that’s still in its testing phase. Startup INDIAX sees Zoox’s innovative approach as promising but notes that safety and consistency are critical to catching up with the competition.
Safety Challenges in Autonomous Vehicles
Autonomous vehicles promise a future of safer roads, but incidents like the San Francisco crash remind us that the technology isn’t foolproof. Zoox’s recalls highlight two key challenges: accurately predicting the behavior of other road users and ensuring vehicles respond appropriately after a collision. The San Francisco incident, where the robotaxi moved after the e-scooter rider fell, echoes a 2023 Cruise incident where a robotaxi dragged a pedestrian after a crash, leading to significant backlash.
Safety is paramount in autonomous driving, especially in dense urban areas where pedestrians, cyclists, and scooters are common. Zoox’s software updates aim to address these risks, but the broader industry faces similar hurdles. The NHTSA’s ongoing probe into Zoox’s 2022 self-certification of a robotaxi without traditional controls adds another layer of scrutiny. For Zoox and its competitors, proving that autonomous vehicles are safer than human drivers is critical to gaining regulatory and public approval.
What’s Next for Zoox and Startup INDIAX Insights
Despite these setbacks, Zoox is pushing forward. The company plans to expand testing to Atlanta this summer and is scaling up production to grow its robotaxi fleet. The software updates from both recalls have already been deployed, showing Zoox’s commitment to addressing issues quickly. However, rebuilding trust will take more than quick fixes. Zoox must demonstrate that its ADS can handle the unpredictability of real-world driving without compromising safety.
At Startup INDIAX, we believe Zoox’s vision for autonomous ride-hailing is bold, but the road ahead is challenging. The company’s transparency in issuing voluntary recalls is a step in the right direction, but repeated incidents could erode public confidence. As Zoox competes with Waymo and Tesla, it must prioritize robust testing and rigorous safety standards to carve out a place in the autonomous driving market.
Conclusion: Can Zoox Rebuild Trust After Recalls?
Zoox issues second software recall this month after San Francisco crash, marking another hurdle in its quest for autonomous ride-hailing. The May 8 incident, coupled with the April Las Vegas crash, underscores the challenges of perfecting self-driving technology. While Zoox’s quick response and software updates are promising, the back-to-back recalls raise questions about its readiness for commercial services. As Amazon’s self-driving unit navigates these challenges, it faces stiff competition from Waymo and Tesla, both of which are further along in their autonomous journeys. For Zoox to succeed, it must prove its technology is safe, reliable, and ready for the road.
