What's wrong?
The master cylinder brake lines on the 2016 Buick Envision carry brake fluid from the master cylinder into the hydraulic brake system. The master cylinder turns pedal force into fluid pressure, and those lines have to hold that pressure every time you press the brake pedal.
On affected Envisions, the inner plastic tube inside the brake line was made with Performaflex instead of the Titeflex material required by GM's specification. That material difference leaves the line vulnerable to cracking. Once a crack opens, brake fluid leaks out and the hydraulic system loses pressure, which changes how the brake pedal feels.
Owners can notice a soft brake pedal. A brake warning light also illuminates when the brake fluid level drops, so either sign belongs in the service conversation with a Buick dealer.

What's the safety risk?
A loss of brake fluid reduces braking performance or can leave the vehicle without braking force, increasing the risk of a crash. If the pedal feels soft or the low brake fluid warning light comes on, stop driving as soon as it is safe and call a Buick dealer. Repair is free at any franchised Buick dealer.
