We own a 2011 Cadillac Sts. Recently my wife was leaving for work and all of a sudden I felt the house shake. My wife was reversing out of the driveway when she applied the brakes. The pedal was so hard she could not press the pedal down. To avoid a crash she put the car into drive to keep it from going into the street. Once she was able to keep the vehicle out of the street she put the car in neutral, but the brakes were still not responding. Thats when our home became our car stopper. I drove the car afterwards and the brake pedal was still hard and would not hold the car from moving when it was put into gear. I contacted the local dealership who informed me that it would take at least 3 to 4 hours labor to diagnose the problem. That at $149.99 per hour. He also informed me that they had a vehicle in earlier saying the same thing and they pretty much replaced all of the braking system on the car at the cost of over $3900. That is crazy to me so I went through the car myself. I replaced all brakes and rotors, replaced the brake fluid and bleed the whole brake system. All that for the next day the same thing happened. I have since traced the electrical side and have found that the vacuum brake assist fuse under the hood was blown. I have replaced the fuse but as soon as you hit the brake it blows the fuse again.

Dash lights fail to come up upon start - sporadic in March 2013, chronic in November to present back up sensors malfunctioning - January 2014 to present power windows go up and down - sporadic Jan 2014 cd/radio volume exceptionally high and then re-adjusts itself headlights turn off when they should be on - 2 occurrences - February 2014 2 emission warning from onstar denied by dealer - Jan - 03/2014 alarm coming through rear-view mirror assembly - very, very loud and persistent - February 2014 I reported several occurrences in 2013. Dealership said they could not duplicate reported chronic occurrences again in November, December and January and February - told could not diagnose complained to corporate who offered to have car diagnosed for 99.00; then charged assigned were $99 per symptom - great way to deter a customer told by corporate this past week that they did not say that and that the car was unfixable. Also told I was out of warranty and any charges were now on me. Can't fix something no one can/will acknowledge exists if consumer doesn't have the money to pursue the matter. Refusal to offer any other support from corporate. I have sent in 3 letters to corporate.
