Vehicle Defect Claims
$1+ Billion Recovered No Fees Until We Win
An Uber or Lyft driver can be operating normally when a critical vehicle component fails. In those cases, vehicle defect claims after a rideshare accident require tracing the problem through the failed part, service history, and inspection record rather than stopping with the crash report.
M&Y Personal Injury Lawyers investigates whether the failure came from a product defect, maintenance or repair work, prior damage, or another cause. That analysis matters for passengers, drivers, pedestrians, cyclists, and others injured in the collision. Call 866-864-5477 for a free consultation.

What Makes a Vehicle Defect Claim Different From an Ordinary Rideshare Crash?

A brake system that does not respond, a tire that separates, or a steering problem may initially look like driver error even when the mechanical condition needs separate analysis. Broader app-status, driver-fault, and rideshare insurance questions remain part of M&Y’s Los Angeles rideshare accident practice.
Was the Rideshare Vehicle Defective or Poorly Maintained?
A mechanical failure does not automatically mean the vehicle had a manufacturing or design defect. The failure might trace to worn parts, a botched repair, skipped maintenance, prior crash damage, or a combination of causes layered on top of each other.
Identifying the failed component is only the first step. The investigation has to determine why that component failed, and the same reported symptom points toward very different responsible parties depending on the underlying cause.

What Happened |
What the Investigation Must Distinguish |
|
Brakes did not stop the vehicle as expected |
Defective component, wear, inadequate service, incorrect repair, or prior crash damage |
|
Tire failed during the trip |
Manufacturing problem, road damage, inflation or tread condition, installation, or prior repair |
|
Steering response changed suddenly |
Defective component, prior damage, maintenance problem, or another mechanical cause |
|
Airbag or seat belt did not protect an occupant as expected |
Whether the safety system was defective and whether its failure increased the injuries |
A brake complaint does not identify the cause by itself. Service records and component examination help separate a product defect from wear, repair error, maintenance problems, or prior damage.
What About Tire Failures?
A tire that separates or blows out during a rideshare trip creates a similar diagnostic problem. The investigation distinguishes a manufacturing defect from road damage, underinflation, excessive tread wear, a prior puncture repair, or an installation error.
The tire’s identification markings, remaining tread, condition of the inner liner, and separation pattern all feed into that analysis. Disposing of the tire before it is examined eliminates evidence that the investigation needs.
What Types of Defects Does California Product Liability Law Recognize?
California’s civil jury instructions maintain a dedicated products liability framework that distinguishes three theories. Each one addresses a different kind of problem with the product.
A manufacturing defect means the particular component or vehicle departed from how it was supposed to be made. The issue is not the design itself but an error during production that made this specific unit different from the intended product. A casting flaw or internal tire-bond problem supports a manufacturing-defect theory when the evidence shows the component departed from its intended specifications.
A design defect involves the product’s design rather than one badly made unit. California recognizes both a consumer-expectation test and a risk-benefit analysis for evaluating design claims. Whether a vehicle’s fuel-system placement or a seat-structure design created an unreasonable safety problem under one of those tests is a factual and technical question the evidence addresses.
A failure-to-warn claim concerns whether adequate warnings or instructions about a known or knowable risk accompanied the product. Not every safety recall is a failure-to-warn case, but information the manufacturer knew and did not communicate to consumers or repair facilities becomes relevant when that information relates to the failure involved in the crash.
What Does California Require Before a Vehicle Is Used for Rideshare Trips?
California’s CPUC requires vehicles used in TNC operations to undergo a 19-point inspection before initial operation and every 12 months or 50,000 miles thereafter, whichever comes first. The checklist includes brakes, steering, tires, lights, mirrors, seat belts, doors, and other basic safety equipment.
Inspection records show what was documented at a particular point in the vehicle’s service history. The crash investigation compares that record with later mileage, repairs, reported problems, and the vehicle’s post-crash condition.
Does Passing a Rideshare Inspection Rule Out a Vehicle Defect?
Passing the required inspection does not establish that every component remained defect-free afterward. A problem develops, worsens, or becomes apparent between the inspection and the crash, so the later failure still requires its own analysis.
A missed or overdue inspection raises a different issue. It leaves a gap in the vehicle’s documented safety history, but it does not by itself prove what caused the collision. The evidence still has to connect the inspection history to the specific mechanical failure.
What if the Defect Did Not Cause the Crash but Made the Injuries Worse?
A vehicle defect operates in two distinct ways, and the investigation has to determine which applies. A crash-causing failure, such as brakes that did not respond or a tire that separated, directly contributed to the collision happening.
An injury-enhancing failure involves a safety system that did not perform as required during a crash caused by something else entirely. Another driver might cause the initial collision, and the rideshare vehicle’s airbag, seat belt, or seat structure then becomes part of the case if it did not protect the occupant as the product was designed and required to do.
The California Supreme Court addressed this principle in automotive design-defect cases, recognizing that a vehicle’s crashworthiness is a separate question from what caused the original collision. A manufacturer or component company faces a separate product-liability claim when the evidence establishes a defect and connects that defect to increased injuries.
That distinction matters because the responsible parties differ. The driver or other motorist who caused the crash bears responsibility for the collision. The manufacturer or component company faces separate questions about the defective safety system’s role in the severity of harm.
Does a Vehicle Recall Prove Who Is Responsible?
A safety recall is relevant evidence, but it does not automatically resolve a vehicle defect claim. NHTSA’s recall database allows searches by VIN for unrepaired recalls and by year, make, and model for broader recall and investigation information. A recall involving the same system that failed in the crash gives the investigation a documented starting point.
The investigation still has to connect the recalled condition to the specific component, crash, and injuries in the particular case. A recall affecting thousands of vehicles of the same model does not establish that this vehicle’s failure resulted from the recalled defect rather than wear, damage, or a repair problem.
An unrepaired recall raises stronger questions because it means a known safety issue remained in the vehicle at the time of the crash. NHTSA notes that its VIN search results do not display every possible situation, including some repaired recalls and newly announced recalls whose VIN populations are still being identified. The recall database is a starting point for the investigation, not the conclusion.
Why Does the Rideshare Vehicle’s Condition After the Crash Matter?
In a vehicle defect claim, the rideshare vehicle and the failed component can be central pieces of physical evidence. Repairing, dismantling, or salvaging the vehicle before it is examined changes the physical condition that investigators need to evaluate.
The failed component itself contains information that photographs alone do not capture. Direct examination reveals details about a brake rotor’s wear pattern, a tire’s internal separation, a steering linkage’s fracture surface, or a seat-belt mechanism’s internal condition that photographs and records alone may not capture.
Once a component is replaced, repaired, or discarded, the original component is no longer available for direct examination.
M&Y identifies the vehicle’s location early in the investigation and works to arrange preservation or inspection before routine towing, storage, insurance, or salvage processes alter or dispose of the vehicle. The firm also obtains the vehicle’s maintenance and repair history, CPUC inspection records, recall status, and prior diagnostic records when available.
Rideshare trip and app data establishing the vehicle’s TNC status at the time of the crash adds another layer that connects the defect investigation to the rideshare context.
Who Bears Responsibility When a Rideshare Vehicle Fails?

Several categories of responsibility arise in rideshare vehicle defect investigations:
- A vehicle or component manufacturer when the evidence supports a manufacturing defect, design defect, or failure-to-warn claim
- A repair facility or mechanic when recent service work relates to the component that failed
- The vehicle operator when the evidence shows the vehicle was operated in an unsafe condition that presented an immediate safety hazard under Vehicle Code § 24002
- Another driver whose negligence caused the initial collision when a defective safety system separately enhanced the injuries
- A TNC-related obligation when inspection compliance or vehicle-approval processes connect to the failure
Assigning all responsibility to the manufacturer before reviewing the vehicle’s service and inspection history is premature. The same failure that looks like a product defect from the outside sometimes traces to a repair error, skipped maintenance, or prior damage once the records and the component are examined.
How Does the Type of Vehicle Failure Affect the Injury Claim?
The type of failure shapes both the causation analysis and the documentation the claim requires. A crash-causing failure like brake loss or tire separation affects whether the collision occurred at all. A restraint or airbag issue concerns the injuries suffered after impact, regardless of who caused the crash.
That difference matters for documenting losses. Medical treatment, future care supported by evidence, lost income, reduced earning ability, physical restrictions, pain and other non-economic harm, and other documented losses all need to connect to the specific failure and its role in causing or worsening the injuries.
A claim involving a defective airbag requires medical evidence showing what the injuries would have looked like with a properly functioning system compared to what actually happened. M&Y documents those connections throughout the case, linking the mechanical investigation to the medical evidence.
Do You Need a Lawyer for a Rideshare Vehicle Defect Claim?
A suspected mechanical failure warrants legal help when the vehicle, failed component, repair records, or inspection history need to be preserved and compared before the evidence changes. A vehicle sitting in a tow yard or insurance salvage process does not wait for the injured person to recover before it is repaired, parted out, or scrapped.
M&Y’s first priority is preserving the vehicle and the failed component. From there, the firm obtains the vehicle’s maintenance records, repair history, CPUC inspection documentation, and recall status. The investigation compares the component’s condition against the manufacturer’s specifications, the vehicle’s service timeline, and the circumstances of the crash.

FAQs for Rideshare Vehicle Defect Claims
Passing the CPUC-required 19-point inspection documents the vehicle’s condition at one point in time. A component that met inspection criteria months before the crash still had time to wear, sustain damage, or develop a latent problem.
The inspection record is part of the evidence, but it does not foreclose a defect claim when the failure involves a condition the inspection was not designed to detect or one that developed afterward.
Recent repair work on the failed system creates a separate line of investigation. The repair facility’s records, the parts used, and the work performed are compared against the component’s post-crash condition. When the evidence connects the repair to the failure, the mechanic or shop’s conduct becomes part of the claim alongside or instead of the manufacturer.
Yes. A crash involving both driver negligence and a vehicle defect raises separate theories against separate parties. The driver or another motorist bears responsibility for the driving conduct. The manufacturer or component company bears separate responsibility for the defective product. California law permits the injured person to pursue both theories when the evidence supports them.
Repairing or replacing the failed component before inspection eliminates physical evidence the investigation needs. When M&Y takes a case involving a suspected defect, the firm sends preservation notices to the parties controlling the vehicle. If relevant evidence was altered or disposed of despite a preservation obligation or notice, that conduct itself raises separate legal questions about the missing evidence.
California Code of Civil Procedure § 335.1 generally gives an injured person two years to file a personal injury lawsuit. Particular facts, including the identity of the parties and the nature of the defect, affect how the deadline applies. Preserving the vehicle and failed component early in the process protects the physical evidence regardless of which deadline ultimately governs the claim.
