2017 chevy impala

[Cowboy55]

I have a 2017 chevy impala and something is draining and killing the battery. I bought the car new and I have already had to put 5 batteries in it. I have took it to the dealership and they told me all of the test they ran on it was showing everything to be working properly. They had no clue what was going on with it. Has anyone else had this problem before? If so what was the cause? Thanks!

Have you replaced any incandescent lamps with LED's?

[Cowboy55]

No I have not. Do I need to?

[Homer1952]

No, but doing so could have caused the issue & service confusion.

 

When I installed a few LED (replacing incandescent) in my 2018 Acadia, the body computer didn't know what to do & that caused the battery to run down.

It confused the dealer too & in 2019 GMC changed the Owners Manual to warn of this issue.  Unfortunately GMC did not update the 2018, last time I checked.

Good luck figuring out the issue.

Thanks. I will let you know when I figure out the problem.
