More and more truck enthusiasts are choosing the 1500 HD as their all-around truck. However, truck owners must be aware of the common problems associated with the Chevrolet Colorado 1500 HD. It will help them resolve these concerns when they encounter them.
The engine fuel rail crossover tube retainer screws of the 1500 HD's 5.3-liter V8 engine were found to be faulty. The said screws may break because they were not manufactured to product specifications. If these screws break, the fuel rail crossover joint may leak fuel leading to the engine stalling. Also, the engine compartment may catch fire if an ignition source is present.
A total of 1,103 units were affected by this problem in 2004. GM released a bulletin informing Chevrolet 1500 HD owners of the problem. Owners were instructed to bring their vehicles to the dealership to have the retainer screws replaced.
Chevrolet Silverado 1500 HDs equipped with an automatic transmission failed to comply with the Federal Motor Vehicle Safety Standard's requirements for "Transmission Shift Lever Sequence, Starter Interlock and Transmission Braking Effect." It was reported that the vehicle's Shift Lever Position Indicator did not illuminate. This may confuse the driver on what gear the vehicle is in, resulting in nasty road accidents.
In 2005, 7,194 units were found to have this problem, and GM advised owners to have their vehicles inspected. The affected units had their instrument panel clusters checked and reprogrammed to resolve the issue.
Popping or rattling noises can be heard from the 1500 HD's muffler heat shield. This was due to the muffler heat shield becoming loose while driving. General Motors has released a muffler heat shield kit that can be used to fasten the heat shield in its place.
