Steering
Reports naming the steering system — racks, columns, power-steering assist and steering linkage.
From owner reports, verbatim
TL* THE CONTACT OWNS A 2006 GMC SIERRA 3500. WHILE THE VEHICLE WAS STATIONARY, THE POWER STEERING FLUID LEAKED INTO THE BRAKING SYSTEM AND CAUSED THE BRAKES TO SEIZE.

THE MANUFACTURER WAS MADE AWARE OF THE FAILURE. THE FAILURE MILEAGE WAS 161,108.
I WAS DRIVING DOWN THE ROAD WHEN THE STEERING WHEEL LOCKED INTO PLACE. I HAD TO JERK IT HARD IN ORDER TO GET IT TO RELEASED FROM THE LOCKED POSITION. THIS HAS HAPPENED TWICE ALREADY. CAN EASILY CAUSE A CRASH. NEEDS TO BE FIXED BY MANUFACTURER. *TR

I WENT OUT TO MY TRUCK IN THE MORNING AND MY DASH BOARD INDICATOR TOLD ME TO GET MY BRAKES CHECKED; EVERYTHING WAS FINE THE NIGHT BEFORE. I BROUGHT THE TRUCK INTO MYMECHANIC AND FOUND OUT THAT MY BRAKE LINE IS CORRODED AND BROKEN. ALSO FOUND OUT THAT THIS A RECURRING AND CONSISTENT PROBLEM WITH THE GMC SIERRAS. I HAVE MY TRUCK SERVICED BY AN AUTHORIZED SERVICE CENTER ON A REGULAR BASIS AND THIS HAS NEVER BEEN MENTIONED TO ME. THIS NEEDS TO BE A RECALL ITEM! SERIOUS SAFETY THREAT. CANNOT IMAGINE WHAT COULD HAVE HAPPENED IF THIS OCCURRED 2 DAYS LATER WHEN I WAS PULLING OUR 40 FOOT RV. SHOULDN'T GM BE RESPONSIBLE FOR THIS? MY TRUCK IS NOW IN THE SHOP GETTING THE BRAKE LINE REPLACED. *TR

Airbags
Reports naming the air-bag system — deployment behaviour, inflators, sensors and warning lights.
From owner reports, verbatim
The front impact sensor, also known as a crash sensor (part # 10370150), is no longer functional. It detects rapid vehicle deceleration during a frontal collision and sends an immediate signal to the Airbag Control Unit (ACU) to deploy airbags. Located behind the front bumper or on the radiator support, these sensors measure impact severity to ensure airbags deploy only when necessary. This part is no longer available from GM or any other aftermarket distributor. It is a critical part for any occupants in a crash. I am just one of many people who cannot make safety corrections.
