Guess which US automaker is rated as worst to deal with by suppliers...

If you guessed Obama's favorite, you win.

DETROIT (Reuters) - General Motors Co , already locked in a public relations crisis because of a deadly ignition defect that has triggered the recall of 2.6 million vehicles, has a new perception problem on its hands.

The U.S. company is now considered the worst big automaker to deal with, according to a new survey of top suppliers to the car industry in the United States.

U.S. lost $11.2 billion in GM bailout, TARP report says The annual survey, conducted by the automotive consultant group Planning Perspectives Inc, asks the industry's biggest suppliers to rate their relationships with the six automakers that account for more than 85 percent of all light vehicle sales in the United States.

Those so-called "Tier 1" suppliers say GM is now their least favorite big customer, according to the rankings, less popular even than Chrysler, the unit of Fiat Chrysler Automobiles , which since 2008 had consistently earned that dubious distinction.
