Chevrolet Silverado 2500 HD Problems
A true workhorse in every sense, the Chevrolet Silverado 2500 HD puts other heavy-duty trucks to shame. With its excellent towing and hauling capabilities, this robust vehicle has radically changed the way people view pickup trucks. Although this HD truck packs a lot of punch in the lugging department, some year models lacked the finesse found in most luxury pickup trucks and SUVs. To some extent, the problems with a few Chevrolet Silverado 2500 HD parts were almost negligible (after all, performance is prioritized over looks), but some models were recalled due to more serious problems in the vehicle.
Fuel level sensor failure
In any vehicle, fuel level readings are very important since they determine how far an automobile would go. In some Chevrolet Silverado 2500 HD models (from 2001 to 2004 and 2006 to 2007), the fuel light would come on even when there is still enough fuel left in the tank. On the flipside, other 2500 HDs would have a full or nearly full tank reading, but fuel levels are in fact close to empty. Chevrolet initiated a recall on several 2500 HD models because of this problem.
The braking system of the 2500 HD and several other Chevrolet pickups left undesirable impact to consumers. Difficulty in stopping was a problem on certain Chevrolet pickup models, and this is all because of the very close installation of the right brake pad to the cross sill. This resulted in braking difficulties, which put the safety of the Silverado 2500 HD in question. The problem necessitated brakes and other Chevrolet Silverado 2500 HD accessories (such as brake pipes) replacement.
Muffler heat shield noise
One of the most common complaints about the Chevrolet Silverado 2500 HD is the rattling noise from the muffler. The annoying, clattering sound is due to the loose muffler heat shield. The noise is noticeable when the vehicle is on idle, but it becomes worse when riders are on the backseat. Although the rattling doesn't affect the truck's performance, it sure is very distracting. Some owners reported that the noise would go away only after the vehicle is warmed up. On other occasions, the sound wouldn't go away completely.
FAQs—Chevrolet Silverado 2500 HD
My Chevrolet Silverado 2500 HD will not start sometimes. Everything comes on when you turn the key, but when you switch to ON position to start the engine, nothing happens. There doesn't seem to be any certain time or day or reason for the problem. How do I diagnose this?
There are several common reasons why this happens and different ways to check the cause of the problem. First, look underneath the dash and ensure that the start signal wire on the starter is clean and tightly secured. If it is okay, go on to the next common cause.
The next time your truck doesn't start, find the starter relay located in the fuse box under the hood and swap it with either the park lamp or radiator fan relay. After that, try to start your truck again. If it works, then the starter relay is broken and needs to be replaced. Note that you can only swap the park lamp and radiator fan relays, as they are the only ones identical to the starter; do not try to swap with other relays.
If the second diagnosis does not help, drop the transmission into Neutral while the truck is in the no-start condition. At the same time, hold the key in start position and place one foot on the brake, then move the shifter between Reverse and Drive slowly. If the starter kicks in, the safety neutral/range sensor is broken and must be adjusted or replaced.
How many quarts of oil does the Chevrolet Silverado 2500 HD take and what happens if I put in too much or too little?
For a Chevrolet Silverado 2500 HD, you must maintain 6 quarts of oil in the tank. In case you put in around a quart more oil than you should, don't worry, this will not ruin your truck. However, make sure not to overfill the oil tank next time, as consistent overfilling can damage the catalytic converter, which is very expensive to replace. In case you overfill the tank with more than one quart, you can drain it easily by siphoning with a tube.
Meanwhile, skipping on your oil change schedule can also cause permanent damage to your truck. A vehicle needs oil because it provides a protective layer to the dozens of moving metal parts in your truck's engine. This significantly reduces friction and heat. When the oil level drops, more components are rubbing together without that protective layer, which produces more heat. This, in turn, can cause the metal in your truck's engine to warp or even melt.
I discovered a knocking noise coming from the right side of my Chevrolet Silverado 2500 HD. What could be making this sound?
There are so many possible causes for this, from a piston slap to a bad camshaft. However, the most common cause is a piston slap, which is actually normal since the Silverado's piston skirt is short and does tend to clack as it ages. If you want to make sure that it isn't serious, you can take your truck to a mechanic or a dealer to inspect it further.

The anti-lock brake technology helped the Silverado drivers to maneuver the truck without much skidding. This system also decreased the stopping distance of the truck, especially on slippery roads. Continued in succeeding models, the anti-lock braking system aided other systems like the Stabilitrak electronic stability control and Hill Start Assist systems.
2006: Maxed towing with VortecMAX
The Silverado heavy-duty truck was beefed up by the VortecMAX Performance Package, which featured a 6.0-liter V8 engine rated at 345 horsepower and 380 pound-foot of torque. This power package improved the 2500 HD’s towing capability, making it the better truck on its new 9.5 rear axle.

Now featuring a turn-by-turn navigation and destination download, the Silverado truck let its drivers to enjoy hands-free calling and interior security to name a few. A subsidiary of General Motors, the OnStar Company had been offering its services to Silverado 2500 HD drivers even dating back in 2001.
2011: A much stronger Duramax
The 2011 Silverado 2500 HD received a revised Duramax engine. The 6.6-liter clean diesel engine with 397 horsepower and 765 pound-foot of torque aided the 2011 model’s stronger body frame in increasing the towing and hauling capacities of the Silverado heavy-duty truck. The new and stronger Duramax engine could also burn B20 biodiesel. Backing the diesel-powered Silverado in improving in the performance department was the new and bigger 36-gallon fuel tank which could extend the total driving range of this heavy-duty truck up to 680 miles.
