Consumer Description

While driving on the highway a message came up stating Brake System Failure, top speed 62 mph. It also came up with other error messages, like service traction control. I completely lost any braking capability and had to let it slow down & pull off to the side of the highway. I shutoff the vehicle and then restarted it & everything seemed fine. I took it to the dealership right away, where they said it had about 20 communication codes across different systems. After 3 days of them having it, they have no idea what is going on. They are now test driving my truck to see if they can get it to happen again (which could kill someone if it does happen again).
