So today I had the windows tinted in the front and the guy left the car in acc mode so it was not running just draining the battery. Now I get the "Charging battery needs service" message. Any ideas on how to clear this or if it actually is a legit.

 

It may be an "Auto Nag" feature. Too long in ACC seems to drain down the 12V battery sooner than other vehicles. Lots of extra fans, pumps, and computers to run. If it was the nagging feature and they started it up, no problem.

 

I got that notice once when I first bought the Yukon nine months ago, also while the windows were being tinted ... I drove it around and it recharged and it's never come back since.

 

Thank you guys! I will try it out tomorrow and let you know.

 

I wanted to know, Hermetics if the error light was finally corrected?
If so, was it done by drving around?

 

My dealer just replaced the battery with no questions even after it was charged by driving it.

 

Yes! Actually no issues when i went back the next day to start her up. I will never leave the car in ACC mode again ...

I am looking for a really good battery though when the time comes to replace the current one, so if anyone has recommendations please let me know.

Thank you!
