I have the car listed above with the tech package. I had left it set for a month or two, went to start, battery was dead. Jumped it and charged the battery, has been starting since. The "battery management system inspection required" message is on with the red triangle warning light. Never noticed it before.
What needs to be done?

We need to check the charging system. Just because the vehicle is starting doesn't mean that it has proper voltage. It could be just the battery or the alternator is not charging the battery properly.

Run through this info and let me know if you have questions. If you are not able to load test the alternator then most parts stores will do it for you.

Hey DARRELL SACKMAN,

You are not supposed to charge the battery in the vehicle on these models. There is also a procedure for jump starting that would be outlined in your manual.

I would first check all of the fuses in the under hood and interior fuse boards.

Guide below:

If all the fuses are okay it may be that the intelligent battery management has deduced you need to replace the battery.

At this age if it has not already had a battery replacement this is likely the problem.

It is not that the vehicle won't start it's that the battery monitoring system has decided it is no longer good enough to operate the start-stop system.

You would need to run diagnostics which would be best done at a dealer. They can run the codes and test the system to see what the fault is.

There is the option to replace the battery yourself, I have attached the instructions for battery replacement which contains a reset procedure for the intelligent battery management system.

These models with the intelligent battery management and start-stop require a special battery specific for these models so ensure you get the correct battery for your vehicle.

Let us know if you have any further questions here.

Hope that helps.

Regards, Joe
