The direct injection pump on mine makes the ticking noise 3 times louder than any other 14/15 I have listened to. Asked the dealers to change the pump and I get the same response : No check engine light equals no problem and GM will not let us change it no matter how loud it is. Been a GM customer since 1988 and I think this is my last chevy. The old "Its Normal" and "working as designed" excuses just don't cut it with me. The silenced/muted text notification issue with the 14 models Bluetooth is annoying as %$#@ too !!!

You have never had a check engine light come on? Or you stabilitrax kick out due to the emission problems the misfires cause?
