Vehicle defect liability plays a crucial role in determining responsibility when a car accident occurs due to a technical failure. From defective brakes to malfunctioning airbags, mechanical faults can turn a routine drive into a serious collision. In California, identifying who is legally responsible—vehicle manufacturers, repair shops, or owners—requires a thorough investigation and understanding of product liability laws.
This article explains what qualifies as a vehicle defect, who may be held liable for resulting accidents, and how injured victims can protect their rights.
What Is Considered a Vehicle Defect in California?
A vehicle defect refers to a mechanical, electrical, or software-related problem that interferes with the safe operation of a vehicle. Common examples include:
-
Brake malfunctions
-
Defective airbags
-
Faulty steering systems
-
Tire blowouts from manufacturing flaws
-
Sudden unintended acceleration
-
Seatbelt latch failure
-
Malfunctioning headlights or turn signals
When any of these issues cause a crash, determining the origin of the defect is key to proving liability.

Who Can Be Liable for a Vehicle Defect Accident?
1. Vehicle Manufacturers
Automakers are legally obligated to ensure their vehicles are safe at the time of sale. Under California product liability law, they can be held strictly liable for injuries caused by:
-
Design defects
-
Manufacturing errors
-
Failing to warn consumers of known dangers
For example, if a vehicle’s brake system was assembled incorrectly and led to a crash, the manufacturer may be responsible—even without direct negligence.
2. Parts Manufacturers
Sometimes, a third-party supplier creates a defective component, such as a faulty airbag. In this case, the parts manufacturer can also be named in a lawsuit.
California law allows victims to sue multiple parties, including both the vehicle and component manufacturers.
3. Mechanics and Auto Shops
A recent repair gone wrong may point to a mechanic’s negligence. If an auto shop installs defective brake pads or fails to detect a dangerous issue, it may be liable.
Repair professionals are expected to act with reasonable care, and ignoring visible safety concerns can make them accountable.
4. Vehicle Owners
Car owners may be partially liable if they knowingly drive a vehicle with safety issues. For example, continuing to use a car with worn-out tires after a warning from a mechanic can reduce or eliminate the owner’s right to full compensation.
How to Prove Vehicle Defect Liability in Court
For success in a vehicle defect claim, the injured person must demonstrate three essential elements.
When a product departs from its expected quality, a defect occurs. The product contained this defect at the moment of its release from production. The actual defect played an explicit role in producing this accident. Vehicle mishaps led to painful injuries, along with damaged property. Evidence often includes:
- Inspection by auto engineers
- Accident reconstruction reports
- Visual evidence comprising images of both vehicle destruction and important road aspects
What Compensation Is Available for Vehicle Defect Victims?
Victims of accidents caused by vehicle defects may recover damages for:
-
Medical expenses
-
Lost wages
-
Pain and suffering
-
Vehicle repair or replacement
-
Future medical or rehabilitation needs
In fatal accidents, surviving families may pursue a wrongful death claim, which can include:
-
Funeral and burial expenses
-
Loss of companionship
-
Loss of future financial support

Real-World Example: GM Ignition Switch Recall
General Motors announced a recall of 2 million vehicles in 2014 because of defective ignition systems. Unaddressed product defects caused the engine to shut off while driving and disabled both airbags and power systems. The issue resulted in at least 124 deaths and provoked numerous wrongful death claims, leading to one of the year’s most significant product liability settlements.
The situation showed manufacturers why prompt product recall remains essential for preventing dangerous consequences related to product flaws.
