The Problem With Tech
We’ve gotten used to the fact that almost all new cars these days are loaded with as much technology and software as possible. Brands will say that these things are necessary and that owners and drivers will ultimately benefit from them. In reality, we don’t notice most of the software our cars use because some of it operates behind the scenes.
What’s scary about those background tech features is that when they go wrong, we really aren’t sure where the issue stems from. Cadillac’s Optiq model is experiencing an issue with braking performance that’s not readily apparent.

Low-Speed Braking
GM Authority reports that some Optiq models are experiencing braking system issues. Specifically, braking performance is noticeably reduced during low-speed driving conditions. GM has issued a service bulletin to address the issue, service update N252528241.
This advisory states that there is a specific issue with the vehicle’s brake system control module. Furthermore, only 2026-year models of the Optiq are affected, and the fix is listed as a software update.
Some of the listed symptoms, according to the bulletin, arise when transitioning from a smooth driving surface to a rough or uneven road. During this, drivers may experience inconsistent braking response. What’s important to understand is that there is no issue or weakness with the braking hardware itself. According to GM, it really stems from the brake system control module adjusting to changing surface types and conditions.

Not a Recall
Another thing the report states is that this is not a recall advisory; GM’s protocol to address this is to have dealers reprogram the brake module with a software update. The update itself will be applied to vehicles still on dealer inventory and sold units as well.
Owners will also have the option to receive the update via over-the-air (OTA) update, saving them a trip to the dealership. The update itself will have a verification process and, in totality, will take 30 minutes to complete
