problem #2

Feb 012012

Sierra 2500 8-cyl Diesel

  • 42,000 miles
I was backing out of my driveway (down hill slope) and lost power steering and braking in my 2006 GMC 2500hd diesel truck. I put the transmission in neutral and deployed the emergency brake to stop. The mechanic determined the power steering pump had failed and this resulted in the hydro boost failure with subsequent brake loss. After replacing the power steering pump the power steering lines split two weeks later.

problem #1

Jun 192012

Sierra 2500 4WD 8-cyl Diesel

  • 40,100 miles
While braking at low speeds and coming to a full stop, truck lurches forward and brake pedal goes down 1/8 of an inch. Driver must use more brake to stop truck ( this is with no load in truck at all, only passenger ). also while stopped and turning the wheel left or right to park, steering wheel looses power steering until brake is released and truck starts rolling. Had truck looked at twice before at dealer for same problem ( once at 32,000 and again at 35,000 ) and was told, as long as no hard codes or failures are found, they were unable to address the issue.
