What's wrong?
The convertible roof control module in a 2016 Buick Cascada is the electronic controller that manages the power soft top. It also coordinates related window movement, so the roof and side glass move in the right order without pinching or binding.
On affected Cascadas, a replacement module intended for European Opel and Vauxhall versions was supplied to some U.S. dealers as a service part. That module uses different window logic than the U.S. Cascada needs. It closes the power windows automatically when the roof closes, and it lets the windows close by key fob from distances beyond 11 meters. That behavior does not meet the U.S. power-window safety standard for this vehicle.
There is no warning sign before failure. An owner would notice the problem only through the window behavior itself, especially automatic window closing during roof operation or remote window closing from farther away than expected.

What should I do?

- Contact a franchised Buick dealer to schedule the free convertible roof control module replacement that restores the correct power-window control.
- Bring the recall notice if Buick mailed one. If not, reference recall number 16V844 when you call.
- Avoid remote window closing and keep passengers clear of the windows until the repair is complete.
What happens at the repair
At the dealer, a Buick technician replaces the convertible roof control module with the correct module and programs it for the vehicle. Parts and labor are covered, so the recall repair is free. Because all covered vehicles are under warranty, Buick is not offering a separate reimbursement program for this campaign. Out-of-pocket repairs already paid are handled through the existing warranty. If you have prior roof control module repair paperwork, ask the Buick service desk how that warranty coverage applies.
