Vehicle sat at the airport for 72hrs. When I left the airport, the brakes felt spongy, but were able to stop the vehicle. On the freeway as I was braking, the brakes began to feel more spongy, requiring increased stopping distance. When I arrived at my residence approximately 45 miles from the airport, I tried to turn into my driveway, only to find I had lost all power steering assist and braking assist. I was able to finally turn in, but had to use my emergency brake to come to a full stop. Once, stopped, I found I could not turn the steering wheel and there were no brakes. I opened the power steering reservoir cap, which immediately spewed a few ounces of P/S fluid over the engine compartment, fortunately not on the hot exhaust. Dealer had the vehicle towed 2 miles to their dealership where they claimed they could not duplicate the problem. However, they did keep it over night and decide to change a P/S pressure relief valve even though they could not duplicate anything. I filed a complaint to GM without anyone taking this serious safety issue as a real problem. This safety issued must be addressed and the root cause must be found before serious injury/death occurs due to this problem.

Vehicle had not been driven for approx. 72 hours. Lost power assisted brakes and power assisted steering on two occasions on same day while backing after starting. Removed power steering/power brake cap on reservoir with engine not running after the second occasion. Fluid blew out of reservoir (approximately 2-3 ounces). Did not drive vehicle at that time. Next time started approx 8 hours later, no further problem. Dealer could not replicate problem the next day.
