Have a 2008 cts DI,

is it possible if have a weak or bad battery for it to start throwing codes or act funny?

had a low voltage message last week, now had check air bag message, trunk will just click multiple times unlocking trunk, cooling fan relay low voltage code, pushed the button that dims radio and the left turn signal arrow showed briefly.

anyone else experience anything like this?

 

Have battery tested, if it's the original you need a new one. As more electronics are added to cars, having a good fully charged battery has become more important.

 

ok replaced battery and erased codes and so far no other codes.


but I am having an issue with my trunk where it will unlock itself multiple times like I am pushing the button, did it like 5 times this morning when I was standing right next to vehicle, it will continue to click ?

 

If it only happens when the remote is close by I would have it tested. Some parts depts will check them for free. If you have 2 or remotes does this happen with all of them or just 1?

 

Thanks slowroll, everything good now. my remote was the issue for the trunk, battery for the codes and after the battery replaced I did find the fuse Emission 1 needed to be replaced now all running and operating as should.
