Airbag deployment sensors have a manufacturing mode to prevent inadvertent deployments while building the car.
But here’s the thing – it’s really important that workers at the factory switch that mode off before the car is shipped out the door. GM employees forgot to do that.…
Last month GM announced an airbag recall affecting 4 million vehicles.
Software errors have been found to disable the front airbags and seatbelt pretensions after "certain driving conditions." GM won't say what those conditions are, but they did say there’s been at least one death related to the bug.
“GM opened an investigation into the issue in June and contacted Delphi, the supplier of the sensing and diagnostic module. The automaker gathered additional electronic data recorder records from other incidents where the same crash symptoms occurred.”
After three days of road tests in September 2016, GM ordered the recall. The affected GMC vehicles include the Sierra lineup as well as the Yukon.
The best way to find out what's wrong with a vehicle is from the people who drive them. Not only do owner complaints help us rank vehicles by reliability, but they're often used to spark class-action lawsuits and warranty extensions. Plus, they're a great way to vent.
