We had the battery replaced on a 2012 Impala by O’Reilly’s. We were warned about possible electrical issues and they used a tool to try to prevent any issues. Unfortunately we are having issues. Our display for speedometer, gas, tachometer and heat/ac, fans not working. Thankful our outside lights, turn signals and brake lights are still working as we are on a road trip. I have read we may need to have our BCM reflashed? The dealership nearby (still traveling) can’t get us in for a week. Is there any tricks we can try. Key fob is also no longer working. Thanks

Replacement of a battery on a 2012 Impala is very straightforward.

The employee of O’Reilley’s installed a bad battery and/or damaged something (think electrical short) when doing the installation. The BCM does not need to be re flashed when a new battery is installed. There is no tool needed to use to prevent issues.

You should contact the auto parts store and obtain their insurance company information, so you can file a claim for the damage and have the car repaired properly.

The fuse for DISPLAY was replaced and everything is working again. Was told a short may have happened.
