Chevrolet Silverado 1999-2006: Common Problems

Learn how well the Silverado 1500 holds up against the scrutiny of everyday drivers.

By Charlie Gaston - June 2, 2015

This article applies to the Chevrolet Silverado 1500 (1999-2006).

The Chevrolet Silverado 1500 is an aggressive vehicle that comes fully loaded with either a small-block Vortec V6 or V8 gas engine and an improved braking system for easy handling around hard corners and rough road conditions. Whether you're hauling heavy cargo loads up to 4K or more, or simply using your Silverado for everyday driving, this highly ranked, best-selling vehicle is one of the most popular on the market. Let's take a look at some of the areas where you may need to devote a little extra care to get the most out of your truck!

Component Breakdown

Transmission

With regular fluid and filter replacements, which should be done every 50,000 miles, your transmission should hold up well over time. However, it must be stressed that it's not a good idea to let too much time to lapse between fluid and filter changes. You could see greater damage from operating your truck with old/foul/contaminated transmission fluid. If your transmission fluid starts to overheat at any point, put in a transmission cooler to resolve the problem.

Check Engine Light (CEL) Displays

The CEL light could illuminate for any number of reasons. Your best bet is to check your trouble codes using an on-board diagnostics (OBD) scanner. If the CEL light does not stay on and the trouble codes won't store properly, see a mechanic.

The most common causes for code, "P301 CYL 1 or 7," include, but are not limited to:

  • Faulty spark plug(s)
  • Faulty fuel injector or coil
  • Intake air leak
  • Incorrect fuel pressure

Engine Misfires on Cylinder 1, 4, 6, or 7 and/or a Ticking Noise

Engine misfires have been reported in the Silverado 1500. Customers report that the service engine light appears, and that the misfire is accompanied by a ticking noise. There are a number of causes for an engine misfire or engine ticking noise. The culprit could be an AFM lifter that unlocks when you start the engine, or one that is permanently stuck. Either way, it's recommended to visit your local Chevrolet dealership or garage for immediate repair work, as this is not a DIY project.

Scheduled Maintenance

The cheapest and easiest way to maintain the health of your engine is to replace your engine oil and filter every 7,000 miles. Some mechanics will insist on replacing your engine oil every 3,000 miles (at a cost to you, of course!). However, using a premium-quality synthetic hydrocarbon engine oil will ensure your engine easily reaches 7,000 miles between changes. Other general maintenance includes, but is not limited to, transmission fluid and filter replacement every 50,000 miles and a brake system flush every 100,000 miles. If you need to replace your brakes for any reason, have the mechanic re-pack your front wheel bearings at the time of service.

Common Questions

What is the basic warranty on the Silverado 1500?

Your basic warranty offers 36 months or 36,000 miles of protection. Added to this, you also have 36 months/36,000 miles of roadside assistance coverage and a 36 months/36,000 miles powertrain warranty, which includes all of the parts of your powertrain. If you experience a mechanical problem related to your powertrain, Chevrolet will pay to have those parts repaired.

How do I replace climate controls in the dashboard?

This is an easy DIY project that should run you as little as $35 for a plug-and-play replacement that fits into your dash with just two simple screws; a trip to the dealer or a local mechanic could cost you up to $200.

Generally speaking, where is the best place to find replacement parts?

For most aftermarket replacements, it's recommended to visit a local salvage yard for the greatest savings. However, if this is not an option, you can also find deals online or by shopping around at local auto parts stores. Your local Chevrolet dealer may also have specials on select replacement parts and repairs.

Common Issues

Rough Idle

The most likely culprit is dirty engine oil. Visit your local dealer for an oil/filter change today. If you're not due for an oil/filter change, you could be dealing with dead or half-dead cylinders. In either case, you'll need to see a mechanic unless you're experienced in making the repair yourself.

Reduced Gas Mileage

Your fuel economy may decrease as you fall behind in your general maintenance schedule. You may also see a decrease in fuel economy while hauling heavy cargo loads.

Service 4WD Message Displays on Dashboard

The first thing you'll want to do is check your fluids. If your vehicle does not shift into 4X4, or requires a longer time than usual to do so, the problem could be your transfer case, which is part of your 4-wheel drive system. The solenoid that holds the 4X4 off, so your truck can be driven in 2-wheel drive, could also be the culprit. Have your vehicle inspected by a professional.
