I have a 2014 Malibu with 171,000 miles. It has worked perfectly up until 6 months ago. It started stalling in traffic intersections and at stop signs, which is a dangerous safety issue. The Auto Stop would engage and then when I put my foot on the accelerator, it stalled out. I would turn the vehicle off and restart it. I took it to countless mechanics who could not figure out what was causing the problem because the Check Engine light did not come on and no codes were triggered. The problem became worse over time and once the vehicle stalled, it would not immediately restart. I took it to my Chevy Dealer and they were baffled as well. They uploaded new software which included the Auto Stop feature, but it continued to stall. They replaced the front battery and checked the one in the trunk. It still stalled. The Dealer said that since the Check Engine light did not come on, they were shooting in the dark. I asked them to disconnect the Auto Stop function, but they said that they couldn't. Unlike other models, there was no disconnection method. I have looked at many on-line chats on the 2014 Chevy Malibu and this defect in the Auto Stop function seems pretty prevalent. No one has come up with a workable solution. I filed a Notice of Claim with Chevrolet corporate and asked them to provide a fix. Does anyone have any ideas of either how to fix the Auto Stop or to disable it? Right now I am shifting into neutral at all traffic signals and stop signs, so that the Auto Stop function does not engage, but that seems like a poor fix to the problem.
