Waymo’s autonomous vehicle program, operated by the Alphabet subsidiary, has faced mounting scrutiny as federal accident data reveals a troubling pattern of sensor-related failures leading to real injuries on public roads. Between July 2021 and November 2025, the National Highway Traffic Safety Administration recorded 1,429 Waymo accidents resulting in 117 injuries and 2 fatalities — numbers that have prompted multiple recalls and a growing wave of legal claims from injured passengers, pedestrians, and cyclists. In one notable case, a cyclist was “doored” by a Waymo vehicle, thrown from her bike, and suffered a traumatic brain injury, with her federal lawsuit still ongoing as of 2025.
The question of whether sensor malfunctions in self-driving cars can form the basis of a viable injury lawsuit is no longer theoretical. Approximately 25 percent of all autonomous vehicle system disengagements in California are tied to sensor or software malfunctions, and Waymo has issued three significant recalls since May 2024 to address exactly these kinds of failures.

How Do Sensor Malfunctions in Waymo Self-Driving Vehicles Lead to Injury Claims?
Waymo vehicles rely on a layered sensor suite — LiDAR, radar, and cameras — to perceive and navigate the world around them. When any layer of that system fails, the consequences can be immediate and dangerous. Known failure modes include LiDAR systems misreading reflective surfaces, radar producing inaccurate distance calculations during rain or fog, and cameras struggling in low-light conditions. These failures can cause the vehicle to miss hazards entirely, misjudge the distance to objects or pedestrians, or execute sudden and unexpected maneuvers that put everyone nearby at risk. The statistics bear this out.
In the first three months of 2025 alone, Waymo was involved in one fatality and 15 personal injury cases. San Francisco, where Waymo operates its densest fleet, accounts for 53 percent of all reported accidents, while Los Angeles accounts for 9 percent. The concentration of incidents in urban environments is not coincidental — these are precisely the conditions where sensor systems face the greatest challenges, from glare off glass buildings to unpredictable pedestrian movement to construction zones that don’t appear on pre-mapped routes. What makes these cases legally significant is that the injured party does not need to prove the vehicle’s “driver” was negligent in the traditional sense. When the car is the driver, the failure of a sensor system is potentially a product defect. That shifts the legal framework from ordinary negligence toward product liability — a distinction that can make claims easier to prove and can expose Waymo and its component suppliers to broader accountability.
What Waymo Recalls Reveal About Recurring Safety Defects
The pattern of NHTSA recalls tells a story that any plaintiff’s attorney would find compelling. In May 2024, Waymo voluntarily recalled 672 self-driving cars after a driverless vehicle collided with a wooden utility pole in a Phoenix alley. The company acknowledged that its software had failed to properly detect pole-like objects and issued an update to address the gap. Less than a year later, in May 2025, Waymo recalled 1,212 autonomous vehicles because a separate software issue was causing low-speed collisions with roadside barriers such as gates and chains. Then came the December 2025 recall, arguably the most alarming of the three.
Waymo filed a voluntary software recall after its robotaxis were documented illegally passing stopped school buses. The Austin Independent School District recorded 19 separate instances of Waymo vehicles blowing past buses with their stop signs extended. NHTSA set a response deadline of January 20, 2026. However, it is important to understand a limitation of recall data: a recall does not automatically prove that a specific accident was caused by the recalled defect. If you were injured by a Waymo vehicle before a recall was issued, the recall can serve as supporting evidence that a known defect existed, but your legal team still needs to connect the specific malfunction to your specific crash. Conversely, if your accident occurred after a recall was issued and Waymo failed to apply the fix to the vehicle that struck you, that failure to remediate could significantly strengthen your case.
The Cyclist Brain Injury Case and What It Means for Future Lawsuits
Among the most closely watched Waymo injury cases is the federal lawsuit filed by a cyclist who was “doored” by a Waymo vehicle. The vehicle’s door opened into the cyclist’s path, throwing her from her bike and causing a traumatic brain injury. The case was still active as of 2025, and its outcome could set important precedent for how courts evaluate autonomous vehicle liability when a vehicle’s automated systems — rather than a human occupant — initiated the action that caused harm. This case is instructive because it highlights a scenario that traditional auto insurance and liability frameworks were never designed to handle.
In a conventional dooring accident, the human passenger who opened the door bears responsibility. But when the vehicle itself controls door operations, or when its sensor system fails to detect an approaching cyclist before unlocking doors, the liability question shifts to the manufacturer and its software. For injured cyclists, pedestrians, and other vulnerable road users, the legal theory is straightforward: the autonomous system had a duty to detect them, it failed, and they were harmed as a result. The broader implication is that each new lawsuit and each new recall filing creates an expanding body of evidence that plaintiffs can draw from. A pattern of sensor failures across multiple incidents makes it increasingly difficult for Waymo to argue that any single crash was an unforeseeable anomaly.
Who Is Legally Liable When an Autonomous Vehicle’s Sensors Fail?
Liability in autonomous vehicle injury cases can fall on multiple parties, and understanding who is responsible matters for anyone considering legal action. Under current legal frameworks, if an accident is caused by sensor defects, software errors, or AI navigation failures, Waymo as the vehicle manufacturer and operator may bear liability under both product liability and negligence theories. But liability does not necessarily stop with Waymo. It can extend to the designated vehicle operator (if one was present), the AV manufacturer, and third-party software or hardware providers whose components contributed to the failure. The tradeoff for injured parties is between pursuing a straightforward negligence claim and a more complex product liability action.
Negligence claims require showing that Waymo failed to exercise reasonable care — for example, by deploying vehicles in weather conditions known to degrade sensor performance. Product liability claims, by contrast, can proceed under a strict liability standard in many states, meaning the injured person does not need to prove Waymo was careless, only that the product was defective and caused harm. Product liability claims tend to be more powerful but also more expensive to litigate, as they often require expert testimony on sensor engineering and software architecture. For most injured individuals, the practical path forward involves working with attorneys experienced in autonomous vehicle litigation who can identify all potentially liable parties. Waymo is a subsidiary of Alphabet, one of the largest companies in the world, which means the resources available to defend these cases are substantial — but so is the potential for meaningful compensation when liability is established.
Why Filing a Claim Against an Autonomous Vehicle Company Is More Complicated Than a Standard Car Accident
One of the most significant challenges in Waymo injury cases is the data asymmetry. Waymo’s vehicles generate enormous volumes of sensor data, telemetry logs, and decision-tree records for every second of operation. This data is critical for determining exactly what the vehicle’s systems detected (or failed to detect) in the moments before a crash. But Waymo controls that data, and obtaining it typically requires formal legal discovery — a process the company has every incentive to resist or delay. There is also the question of federal preemption.
Autonomous vehicle regulation sits in an uneasy space between federal authority (NHTSA oversees vehicle safety standards and recalls) and state authority (states regulate driver licensing, insurance, and traffic law). Some legal scholars have argued that federal safety standards could preempt certain state-law claims against AV manufacturers, though this theory has not been definitively tested in court. If you are considering a claim, be aware that Waymo’s legal team may raise preemption as a defense, and your attorney should be prepared to address it. A practical warning: statutes of limitations apply to autonomous vehicle injury claims just as they do to any personal injury matter. These deadlines vary by state — California’s is generally two years from the date of injury — and missing them forfeits your right to sue regardless of how strong your case may be. Do not assume that because the technology is new, the legal timelines are more flexible.
The Role of NHTSA Data in Building Your Case
NHTSA’s Standing General Order requires autonomous vehicle operators like Waymo to report crashes, and this data is publicly accessible. For injured individuals, NHTSA reports can serve as independent corroboration of accident details and can reveal whether the vehicle involved in your incident was subject to any open recalls at the time. The fact that 1,429 Waymo accidents have been reported to the agency through November 2025 means there is now a substantial database of incidents that attorneys can mine for patterns — repeated failure modes, geographic clusters, and common injury types that support claims of systemic defects rather than isolated malfunctions.
What Comes Next for Waymo Injury Litigation
The trajectory of Waymo injury litigation is pointing toward more cases, not fewer. Waymo continues to expand its operating territory into new cities, each with its own road conditions, weather patterns, and infrastructure challenges that will test the limits of its sensor systems in new ways. Every expansion increases the vehicle-miles traveled and, statistically, the number of incidents.
Meanwhile, the legal infrastructure for handling these cases is maturing — more attorneys are developing autonomous vehicle expertise, more expert witnesses are available, and more judicial precedent is being established with each filed case and each recall. The open question is whether regulators will move faster than the courts. If NHTSA or state agencies impose stricter pre-deployment testing requirements or mandatory sensor redundancy standards, the number of sensor-related injuries could decline. But if regulation continues to lag behind deployment, the courtroom will remain the primary venue where the safety of these systems is contested, one injured person at a time.
Frequently Asked Questions
Can I sue Waymo if I was injured by one of its self-driving vehicles?
Yes. If a Waymo vehicle caused your injuries due to a sensor malfunction, software error, or navigation failure, you may have grounds for a claim under product liability or negligence theories. Waymo, as the operator and an Alphabet subsidiary, can be held liable for defects in its autonomous driving system.
What kind of sensor failures have caused Waymo accidents?
Documented failure modes include LiDAR systems misreading reflective surfaces, radar producing inaccurate readings in bad weather, and cameras struggling in low-light conditions. These failures have led to collisions with utility poles, roadside barriers, and failures to detect cyclists and pedestrians.
How many accidents has Waymo been involved in?
According to NHTSA data, 1,429 Waymo accidents were reported between July 2021 and November 2025, resulting in 117 injuries and 2 fatalities. In the first three months of 2025 alone, there were 15 personal injury cases and 1 fatality.
Does a Waymo recall help my injury case?
A recall can serve as evidence that a known defect existed in the vehicle’s system, which can support your claim. If the recall was issued before your accident and the fix was not applied to the vehicle that injured you, that fact could significantly strengthen your case.
How long do I have to file a lawsuit after a Waymo accident?
Statutes of limitations vary by state. In California, you generally have two years from the date of injury to file a personal injury lawsuit. Missing this deadline can permanently bar your claim, so consult an attorney promptly.
Where do most Waymo accidents happen?
San Francisco accounts for 53 percent of all reported Waymo accidents, reflecting the density of its fleet operations there. Los Angeles accounts for 9 percent. Urban environments with complex traffic patterns tend to produce the most incidents.
