2015 Buick Regal AWD Service Notifications

[Maryeball97]

Hello! completely new to this forum, hope I'm posting in the correct place.

About 6 months ago I bought a 2015 Buick Regal AWD turbo. It now has about 40,000 miles on it. (Disclaimer I will be going to the dealership this weekend). I'm wondering if anyone has had the "Service All Wheel Drive" along with "Service Rear Axel" pop up on their car. My car has been driving fine no weird vibrations, no clunking nothing out of the ordinary that would alert me something is wrong with my axel or anything. I have been driving the last 2 days and the notifications has not popped up since... Also to note usually I would get a notification on my app something is going on with the car and I have not received any notification.
Has anyone else experienced similar?

You should have the Haldex filter and fluid replaced though there is no mention of this in the Owners Manual. Here is some reading material for the Haldex 4 system.

Super late update but it was the rear differential clutch control module. Thankfully covered under a warranty I purchased!

Also the rear differential pump

Also the rear differential pump

Those are the expensive parts, the filter and fluid are around $100. Stay on top of the maintenance on the AWD, you can do it at home.
