My 2010 G6 had issues with staying running and then just didn't start at all. Took it to the shop and they replaced fuel filter and MAP sensor. Said all codes were cleared from the reader. When it starts it runs great, can't even hear that it's running, which it hasn't done in years. However it doesn't always start and when it does start it stalls, mostly when taking turns. Mechanic said he can't figure out what the issue is. He says from what he can see all is well so he doesn't know who is doing this. He says he thinks it may be computer related but he's not really knowledgeable about computer issues. Any ideas? I've spent almost 1300 in the last year to have a car that still doesn't run. I'm trying to decide if I should just cut my losses or invest another 500-1000 and hopefully get things right. I can't bit a mm car for that so in that way it seems like a good idea. However there's no promises that after doing so I'll have a running vehicle lol.

I have a 2009 G6 3.9L convert and have had had similar experiences
Finally narrowed down to either cable from engine computer or the passenger side internal dashboard connection module
I did not have any electrical responses disconnecting the battery and cables on both sides resolved the issue
Ito only throughs a communication code every now and then when testing.
I greased the fitting with low voltage grease and it has an mostly resolved the issue...still need to replace whatever is shorting...
good luck...very frustrating..
