GMC Stabilitrak Engineer | The People Behind GMC

Marcey Kewish, GMC Product Development Engineer on Chassis Control, is proud to have grow up in the Michigan Automotive Industry with a mechanic father who worked in a machine shop. After Marcey graduated from the University of Michigan she already knew she wanted to carry on the tradition and work in the automotive industry. Currently she is going back to school to get her masters and has to balance work life, personal life, and school life which exhibits the qualities of what it takes to be Professional Grade. This drive for achievement carries over in her work at GMC. She is proud to be responsible for the "button on the dashboard with the squiggly lines". This button, for the Stabilitrak system, she develops for full size heavy duty trucks and vans. At the GM Proving Grounds she attempts to replicate driving situations that require Stabilitrak, such as a truck and trailer going into a jackknife, similar to a guy who would be hauling a fifth wheel camper on vacation. Her focus on achieving great things contributes to GMC's dedication to build the world's best vehicles. For more information visit
