Code c 2638 and c25D6

You car is equipped with SBC brakes. Its an electronic braking system or brake by wire. The pump does have a service life and your may be close to the end. If this is a red warning in your cluster you need to stop driving right away and call a tow truck. If its a white warning you have some time but I still recommend bringing it in right away. They did extend the warranty for this issue but its more likely you are past the deadline. Either way call your dealer with the VIN number to see if the extended warranty on the SBC pump still applies and don't drive the car. Alex
