My 428 had recently started to hesitate when it sits for multiple days. I do charge the battery frequently. The other day when I started it failed to start the first time and the chassis stabilization error came on. I then proceeded to start it again and it was fine no lights. Any insight on this ? Thanks

You have to diagnose the error codes, easiest way is through OBD port, or there is no way of knowing the cause. is check engine light on? What does vehicle system status say on idrive?

I have no check engine lights or warnings on in I drive. Should I take it to the dealer since I have warranty ? Or just wait and see if it does it again ?

If you bring to the dealer they will need to be able to replicate the issue. Which means you would have to ask them to let it sit for multiple days then start it and hope it shows an issue or check engine light.

In my experience having a similar issue, it's a waste of time bringing it in unless there's a check engine light or it can be replicated.

Where have you been buying gas? This issue seemed to go away for the most part when I switched to Chevron 91 (SoCal)

I also recommend buying a Foxwell NT510 scanner to pull up any stored codes

Update car did it again this weekend. After I parked in a hill and let it sit for 10 min it did it really bad. Then it was fine the rest of the day. Any idea what it could be? I will be dropping it off at bmw in the morning. I feel like it could be a fuel pump issue

They should be able to find the drivetrain malfunction history and go from there.

Update: the dealer had the car for a week. They replaced the battery and replaced the ignition control module under warranty.
