In what sounds like an urban legend spread by a competing car manufacturer, defective seat belts in GM pickup trucks have been setting the vehicles' carpet on fire. And now General Motors is recalling more than 640,000 Chevy Silverados and GMC Sierra 1500s because of the issue. GM officials say a high-tech seat belt in the trucks creates a small explosion that locks the belt when a crash occurs. The explosion releases hot gas through a bracket opening that can catch the carpet on fire. The company is urging owners of 2019 and 2020 models to bring their vehicles to the dealership, where the bracket opening will be sealed at no cost. If you own a Silverado or Sierra and don't bring it in to be fixed, would GMC be cleared of responsibility if your vehicle caught fire? What's the biggest thing you've owned that was recalled?
