FRESNO, Calif. (KFSN) -- General Motors has announced six new safety recalls. This latest round of call-backs involves 7.6 million cars with model years dating back to 1997. [br /][img SRC="http://dig.abclocal.go.com/kfsn/Images/063014-Six-Recalls-Chart.jpg[br /]" ALIGN="" /][br /]So far General Motors has recalled more than 28 million cars. But workers at a local dealership say the recalls have not hurt sales there but have put a big strain on their service center.[br /][br /]Hedrick's Chevrolet is inundated by customers concerned about recalls including the latest one involving faulty ignition switches which power up your car. But despite the safety concerns, we found customers who still feel comfortable buying the American brand. "GM makes a good quality product. They're fixing it. As long as you bring it in time and fix it. If you don't and you're negligent on that, it's on you," said Ralph Beckmann. [br /][br /]About ten percent of all cars fixed in the Clovis service center are being worked on because of recent recalls. " Our service department has been very overloaded for the last four months. There were so many recalls at once the supplier was having a hard time producing enough parts," said Brett Hedrick. [br /][br /]General Motors says the company is aware of three deaths, eight injuries and seven crashes involving the same cars included on Monday's recalls but added there's no evidence the defect caused the deaths. Brett Hedrick says none of those cases happened locally. "It doesn't matter if they bought the car here or not. If they are in my area and General Motors sends the consumer a letter and says please take it to your nearest dealer, I can do the work for General Motors," added Hedrick. [br /][br /]GM is asking drivers to remove everything from their key rings until affected cars are repaired. Local mechanic Richard Lindsay says that's because a very heavy key chain can add pressure and wear down your ignition switch. "It weakens the key cylinder a lot. It puts a lot of stress on the ignition part of the key cylinder," said Lindsay. [br /][br /][br /][br /]
