• Hint: Use a descriptive title for your new message
    If you're looking for help and want to draw people in who can assist you, use a descriptive subject title when posting your message. In other words, "2008 LaCrosse" isn't going to indicate to anybody that you need help. However, "Need help with my 2008 LaCrosse" will. Be as descriptive as you can. Please use common sense...

It needs to scanned by a dealer and then repaired under warranty if needed as it's still covered in 2018. You can always read the owners manual information about warnings and what they mean.

It could be many different things. Need to scan the ABS and Chassis fault codes.

Brake Assist works in conjunction with the Stabilitrak and ABS through the hydraulic brake control module.
