2005 GMC Yukon Denali XL Brakes Problems

“I live in san francisco and was driving down my street. I live on a steep hill and my brakes and power steering failed. I had my truck towed to the nearest repair shop and found that there is a known defect in the gasket between the power steering and the brake system. It fails. Gmc knows this. I have had this gasket replaced three times in 5 years and it has failed again. What can I do?”

Had the sense to have it towed to the dealer; for the $2400 estimate, they also said that my transmission lines were leaking so estimate also included the labor/parts to replace both sets of lines to fix both line related issues. …”

“I was traveling on a local highway at the posted speed limit when I was caused to slow due to traffic. When I pressed the brake pedal the pedal went completely to the floor. Scared to death I almost engaged the emergency brake to ensure the vehicle would stop in time. Mind you I was traveling with three children and my spouse in the vehicle all of whose lives could have been affected not to mention my own.
