GMC Sierra HD Problems
The GMC Sierra HD, produced from 2001 to 2007, was one of the models that's part of GM's full-size lineup. What set this truck apart from its competitors was the inclusion of different luxury trims to its big, powerful, and brute packaging. As good as the vehicle was, it wasn't free of problems. Owners experienced various mechanical issues that risked safety, handling, and control. Despite a short, six-year production span, there are already certain and common issues worth mentioning that needed recalls and service bulletins of the truck. Here are some examples.
The power steering of the GMC Sierra HD is prone to fail because of a power steering hose that's not fit to be used on the truck. A full turn of the wheel to either side, while the stationary, may put too much stress on the system. Push it to its limit, the hose has the tendency to completely break and the power steering fluid to leak out. Steering becomes increasingly difficult because of the extra effort needed to turn the wheel. Fluid coming into contact with the hot engine compartment can cause fires. For some models with advanced brakes, even braking might be compromised as an effect. A quick replacement of the hose with the right one should take care of this problem.
For units with an advanced-wiper system, there is a chance of damaging the electrical wires running to the components because of an overheated circuit board. This is usually signified by an odd smoke or smell from the assembly. If left unattended, a fire may start within the area because of the bad wires. Simple modifications on the wiring setup will prevent this from happening.
The parking brake's friction lining has a tendency to become too thin. Owners may find the truck moving and crashing towards other cars or fixtures despite having the brakes engaged. Depending on the type of brakes used on a certain unit, the GMC dealer should install a clip retainer, or a completely new parking-brake cable assembly to prevent the problem from occurring again.
Replacement fuel filters from the Fram brand may have loose o-rings, gaskets and seals. It is feared that the bad seal may lead to leaks in the system. This has the potential to catch fire if ignited. Fram offers a free replacement of the defective unit as a solution.
FAQs—GMC Sierra 1500 HD
Why does America have such an obsession with muscle pickup trucks?
In the United States, the work ethic can be summed up as "If you ain't gonna do it, it'll never get done." It is this do-it-yourself work ethic that fuels the workingman's passion for strength and dependability, especially when it comes to equipment.
In 2001, the GMC Sierra 1500HD was created for the work-oriented customer wanting to exploit the full towing and hauling potential of a half-ton truck. The crew cab body was unique to the Sierra 1500HD from 2001 to 2003. A 6.5-foot cargo box was the only bed length available with the GMC Sierra 1500HD. A truck operating on a heavy-duty suspension system, the Sierra 1500HD crew cab was featured with rear-wheel drive and four-wheel drive.
Where does the GMC Sierra 1500 HD get all its brawn? Does all that muscle mean fancy luxury features can't be enjoyed?
The truck came standard with a 6.0-liter Vortec V-8 engine generating 300 horsepower and 360 pound-feet of torque. Together with four-speed automatic transmission, the Sierra 1500HD's maximum towing capacity was rated at 10,300 pounds.
Truck owners certainly love to play hard too. Capable of seating up to six adults, the GMC Sierra 1500HD offered an impressive amount of comforts for traveling to and from a job site. Air conditioning, power windows, dual front airbags and a stereo system with CD player are some of the standard equipment found inside the Sierra 1500HD.
I recently reached 125,000 miles on my GMC Sierra 1500HD. I'm wondering what maintenance I should do for the motor, transmission, differentials, etc to keep her going.
If you haven't owned the truck its whole life, it's more practical to just change them all so you know where everything's at. Don't forget to check your air filter -- sometimes it's easy to overlook.
Next, inspect plugs and wires to see if everything's in place. Now, it's best to look into steering components and see if there is any play. If you do, decide where it's coming from and replace. Shocks wouldn't hurt if not already done.
Lastly, check all four breaks for age. If you've got a soft or spongy brake pedal, consider replacing them with new brake lines and master cylinder. Remember to replace your brake fluid as well. Check your exhaust system for rust. Replace rusted sections and make sure your hangers or heat shields are all on well.
Why can't I get an accurate fuel reading from my fuel gauge?
This isn't the first time a fuel level sensor in the Sierra's fuel tank has read the fuel level incorrectly. The sensor needs to be replaced to resolve the issue. Experts recommend having the complete fuel pump module replaced for high-mileage vehicles.
How come the temperature on the passenger side isn't as cool as we like? The A/C seems to be working fine.
In this situation, one or more heater & AC (HVAC) temperature and/or air delivery mode door actuator may fail, resulting in improper temperature or air delivery. When this occurs, try looking up the fault code stored in the HVAC control module that should help diagnose then issue.
