I have a 2008 Impala LTZ. About 6 weeks ago, I had AAA replace the battery, and this morning the car just lost power when I stopped at a light. It came back on after a few seconds, and the car started right up, but this is the second time it’s happened since the new battery was installed. The cables seem tight, so I’m wondering if it could be the cable itself or maybe it’s just not tight enough. Any thoughts?
Are all connectors and connections clean? How’s the ground cable to the body?
Sounds like a loose connection or maybe a bad ground. Definitely check those cables again.

Thanks! I’ll look into that. I didn’t think about the ground connection.
You might also want to check the alternator. If it’s not charging properly, that could cause power issues.
Have you had any other electrical issues? Sometimes a failing sensor can cause weird power loss too.
