Car will stall out and won't go at time without pumping the gas. We have replaced vacuum pump and both O2 sensors. Power steering locks up when hitting a small bump, won't start unless I moved the drivers seat up and back, if I use the blinkers my radio goes off if I use my high beams the radio freezes. It will do weeks with no issues then one day it will start acting up and does it for days or weeks. Chevy says there is no recap for that model but I've read multiple complaints about the same things so why is it not being addressed by gm.
