While driving, I was getting ready to turn into the left lane then I noticed the brake pedal was hard as a rock so I immediately pulled over into a community. I knew it was safe I could barely stop the vehicle because the brake pedal was not giving at all, but eventually, I was able to stop I believe if the terrain wasn’t uphill, I wouldn’t have been able to stop my husband came and assisted with driving the vehicle to the dealership at a very low speed and hazard lights, which was about 20 miles away. This was very scary, but we made it since then the dealership has diagnosed it and it has something to do with brake assist power pump failure, which is documented in a class action lawsuit in

The vehicle experienced a complete loss of infotainment/audio functions immediately following a GM over-the-air software update. The OnStar indicator turned red, all vehicle audio including turn-signal sounds stopped functioning, and the rear backup camera stopped displaying an image. The backup camera failure creates a safety concern because it eliminates a federally required rear visibility safety feature. GM has advised me that software updates do not cause these problems and instead reveal an underlying issue. However, GM Preliminary Information bulletin PIT5971B identifies a software anomaly associated with loss of audio and a red OnStar LED on affected GMC Terrain vehicles, which close
