DETROIT -- General Motors has buried the hatchet with its suppliers.
According to the Henke survey, which was released Monday and evaluates the purchasing policies of North America's six biggest automakers, suppliers ranked General Motors just behind Toyota and Honda.
Ford and Fiat Chrysler ranked fourth and fifth, while Nissan plunged to last place. The report drew its conclusions from questionnaires filled out by 652 salespeople that work for 108 Tier 1 suppliers.
GM's ascent and Nissan's decline have gained momentum over the past two years, according to the survey.
GM "is making really great strides in their overall relations," said John Henke, author of the survey and president of Planning Perspectives Inc. of Rochester, Mich. "The suppliers are saying, 'We can really do a great job.'"
In 2011, GM began to roll out more collaborative policies such as no-bid contracts. In 2015, the company followed up by asking approximately 500 suppliers for feedback. Vendors filled out scorecards that rated GM's purchasers.
