Safety-related Defect Investigations

A safety-related defect is a problem that affects the safe operation or functioning of a vehicle, tire or child car seat. In order for a defect to be considered safety-related, it must have originated at the design, manufacturing or assembly stage, or it must interfere with the functioning of the vehicle, tire or child car seat. The defect must also be present in a group of similar vehicles, tires or child car seats, and it must directly endanger the safety of a person, which includes drivers, passengers, the occupants of other vehicles, pedestrians, cyclists and other road users. Finally, the problem caused by the defect must occur with little or no warning and not be due to everyday wear and tear, a lack of proper maintenance, or negligence on the part of the owner.
