I began experiencing severe transmission shuddering and harsh shifting, especially at lower speeds or under light acceleration. When the issue occurs, I press the gas and the engine revs up to 6,000 RPM without reaching 20 MPH, making it extremely difficult \u2014 and dangerous \u2014 to merge into traffic or cross intersections.  This issue has worsened over time and is now a critical safety concern, especially with children in the vehicle. I have researched this issue and found that many owners report the same transmission defect, and there is an open class action lawsuit and a GM Technical Service Bulletin (TSB #18-NA-355) describing the exact symptoms.  The vehicle has become unsafe to drive. GMC should issue a recall or mandatory repair program for this known defect before someone is injured or killed.","products":[{"type":"Vehicle","productYear":"2018","productMake":"GMC","productModel":"SIERRA 1500","manufacturer":"General Motors, LLC"}]}]}
