“Gm had a injector problem (recall ) in 2006. They replaced mine on sept,27 2006. On may 21 20013 I had the same problem in which GM conveys they can't fix it again. The mileage on may, 21 was 84362, just about how long the others lasted. I was told from my local GM dealer that they are several other owners with this same problem (thousands). I just waited to pass my grief along to let someone else know how you are treated by one of the companies that we bailed out with our monies.”
