 On two separate occasions (the second date was about 2 months ago), i have had to make very hard stops at freeway speeds. both times, the car came to a stop with the anti-lock brakes functioning properly (brake pedal vibrations indicating correct modulation). once the car comes to a complete stop however, the brakes suddenly failed completely. the brake pedal goes to the floor with absolutely no back pressure. the car begins to roll again, indicating the brake caliper/pads have released the disk. the only way i was able to stop again was to pump the brake pedal, activating the stability control module to boost hydralic pressure to the braking system. this seems related to the previous issue of brakes not functioning on start-up due to low vacuum. following a hard stop, the vacuum boost to the brakes apparently becomes depleted, causing braking system failure. i have reported this to my dealer and they have been unable to re-create the problem. due to the potential dangers this presents, i felt it important to report this since the dealership seemed unwilling to pursue the issue.

 I have a brake failure problem on my 2008 pontiac solstice gxp with 2.0 turbo engine. after starting car i proceeded to back out of garage, after backing up 5 to 10 feet i stepped on the brake to stop car and car would not stop. had to push on brake pedal several times very hard and to pull on the emergency brake to finally get it to stop. if there had been anyone on sidewalk behind my at the time it could had resulted in a bad accident. then i took my car to dealership and they told me they had never heard of this happening. after leaving car at dealership a day or 2 i went back and they had found a service bulletin ( document id# 1982132 ) dated 6/04/2007 about this problem which stated that this was normal on the pontiac solstice gxp and the saturn sky and there was nothing they could do. after that i spoke with the general motors rep. and the service manager and he told me the same thing but he would check in to the problem and get back with the service manager with the findings. after a week i received a call from the service manager and was told that general motors was writing a new software program and that it would not be ready for 2 or 3 months. that was on november 3, 2007. after waiting for 3 and did not hear anything from dealership i called they and was told that the software was ready and i could bring my car back and they would install the new software to solve the problem. the new software was install on 3/3/2008. i returned to dealership to pick-up my car only to find that the new software did not solve the problem and was told by the dealership that they could not do anything and that they were at the mercy of general motors to solve the problem. this braking problem was not a one time occurrence and it happens every time you start the car when it is cold, even after driving car and the letting it set 4 or 5 hours it does the same thing. so i consider this a safety issue and would like to have it resolved before someone gets hurt or killed. *tr

 This complaint is identical to one already filed with the nhtsa, representing a potentially hazardous safety issue. while backing out of the garage from a cold start in my new pontiac solstice gxp delivered only one week earlier (mileage at one week=200), the brakes failed with the car in reverse and the car continued to roll backward (fortunately without power applied down a slightly inclined driveway. when put into drive, the brakes responded. later in the day, from a cold start, the brakes failed again momentarily while pulling out in drive. the dealer service department was very responsive and diagnosed a failure of the valve in the master brake cylinder that allows pressure to build up in the hydraulic lines. the part is on national back order as a stac order. i was told that no spare parts have yet been stocked to fix this problem anywhere in the country. the dealership put me immediately in a rental vehicle at gm's expense until the part comes in, which could be 2 days, 2 weeks, or 2 months as the service manager said. could this be a manufacturer's defect present in all brake master cylinders, perhaps outsourced, delivered to the solstice gxp assembly line in delaware? *tr
