2009 Impala, owned since 2011. Started to give us issues a year after purchase where we would get no crank, no start. Replaced battery thinking it was the issue. It worked for a couple of days and started over again. No crank, no start. Replaced starter with autozone brand and it worked fine a few days. It started to happen again, no crank, no start. Replaced starter with oem from gm. It worked for a couple of days and the issue started to happen again. No crank, no start. Replaced starter relay, pulled bcm and cleaned all contacts. After cleaning bcm contacts it seemed to of worked but a few weeks later it gave us the same problem. Changed ignition switch and continued to have the same no crank, no start issues. We just continued to live with it. The car cranks after 5 or 6 turns of the key and became apart of our daily life. Now the big issue is the car turned off on us while driving a few days ago. Let it sit 30 mins. And tried to crank but we were getting no crank no start. It eventually cranked and started but I'm worried because I have my grand kids with me often and fear if im on the highway I can get into a serious collision. Airbag light has came on since then and can't afford to go to the dealership to get the vehicle diagnosed. I've called gm and since the vehicle is no longer under warranty I would be responsible for everything. Have also checked the cables to make sure they are tight and free of corrosion. No oil drips on the starter. We give the car scheduled oil changes and take care of it very well.
