The brake pedal pushrod retainer is a small part that keeps your brake booster connected to the brake pedal. In some 2005 Chevrolet and GMC SUVs, this retainer might be missing, which could cause problems.
Risk if Unfixed
If the retainer is missing, the brake booster could break free from the pedal, leading to a complete loss of brakes. This could cause you to lose control of your vehicle and increase the risk of a serious crash.
Free Fix
Your dealership will inspect your vehicle and install a new brake pedal pushrod retainer if it's missing, at no cost to you. You should have your vehicle checked as soon as possible.

The hydro-boost brake system in your vehicle uses a special reservoir called the accumulator to help boost your brake power. In some cases, this accumulator can crack and separate from the system while you're driving.
Risk if Unfixed
If this happens, sharp fragments from the accumulator could hurt people nearby, especially if you're working under the hood. If the accumulator cracks, it could also cause your brakes to fail without warning, leading to a sudden loss of control and a possible crash.
Free Fix
Your authorized dealership will check the hydro-boost assembly to make sure it's working properly. If it's not, they'll replace the entire assembly for free. This repair is at no cost to you, and you should schedule it as soon as possible.

Original — What Happened
CERTAIN TRUCKS, SPORT UTILITY VEHICLES, AND VANS EQUIPPED WITH BOSCH HYDRO-BOOST BRAKE ASSEMBLIES, THE HYDRAULIC BRAKE BOOSTER PRESSURE ACCUMULATOR MAY CRACK AND SEPARATE FROM THE HYDRO-BOOST ASSEMBLY DURING NORMAL OPERATING CONDITIONS.
Original — Risk if Unfixed
IF A SEPARATION OCCURRED AND THE HOOD OF THE VEHICLE WERE OPEN, FRAGMENTS FROM THE ACCUMULATOR COULD CAUSE INJURY TO PEOPLE IN THE IMMEDIATE AREA. THE PRESENCE OF THIS CRACK OR FRACTURED SURFACE COULD ALLOW THE HYDRAULIC FLUID TO LEAK FROM THE ACCUMULATOR CIRCUIT OF THE BOOSTER ASSEMBLY. THE LOSS OF FLUID WOULD CAUSE INCREASED STEERING AND BRAKING EFFORT AND A CRASH MAY OCCUR WITHOUT PRIOR WARNING.
