NHTSA Complaint #11422626 — 2017 CADILLAC ESCALADE ESV

I was travelling down the highway and the brakes failed to respond. I was able to deliver the car to a Cadillac dealer in Holland Michigan. At highway speeds with no breaks I believe my families lives were in danger. We have brought the car into the dealership multiple times for electrical system issues and I believe these unresolved issues have culminated in the failure of the braking system at high speeds. The dealer has stated that it was a vacuum pump and it has now been replaced but found no other issues with the electrical system. There was a warning light for the brake assist feature during the drive prior to the brakes not functioning. We reported this to the dealer during the drive and they made an appointment for the following Thursday (this was on a Saturday). We were not notified at the time of the call that this issue could put our lives in danger or that we should stop driving the car.
