The GM Canada class action lawsuit was filed by a plaintiff who purchased a 2005 Chevrolet Silverado 2500 in April 2005. The lawsuit doesn't allege the plaintiff's truck suffered any airbag or seat belt pretensioner failures, but the plaintiff says his 16-year-old truck has lost value because of the sensing and diagnostic module.
Also called the airbag control unit, the module is connected to sensors placed all over the vehicle and is used to deploy the airbags and seat belt pretensioners in a crash.
However, the class action, which includes all consumers in Canada except the Province of Quebec, says the sensing and diagnostic modules have software calibration defects. The alleged defects cause failures of the airbags and seat belt pretensioners to deploy when they are needed the most.
The lawsuit alleges a typical "crash duration" of a frontal vehicle-to-barrier collision lasts about 80-150 milliseconds (0.08-0.15 seconds). But the General Motors airbag control unit was allegedly calibrated to prevent deployment of the airbags and pretensioners 45 milliseconds after a crash has begun.
This means the module was allegedly calibrated not to deploy the airbags after 45 milliseconds even if the module continues to receive crash information for up to 80-150 milliseconds.
According to the plaintiff, this is a problem in real-world crashes that last more than 45 milliseconds where multiple impacts occur.
GM allegedly knows about the airbag control units and knows customers are in danger, but the class action claims the automaker has concealed the defects to avoid the cost to order a recall.
GM also allegedly continues to claim the vehicles are safe even though hundreds of customers have complained about airbags that failed to deploy.
The GM Canada class action lawsuit was filed in the Supreme Court of British Columbia: William Arthur Baldridge, v. General Motors Company, et al.
The plaintiff is represented by Garcha & Company.
