The steering may develop a clunk type noise from the upper intermediate steering shaft. Our technicians tell us that you should check with you local GM dealer to find out what the latest repair is for this condition.
The speedometer or other instrument panel gauge may begin to work erratically at times. Our technicians tell us that the instrument cluster must be sent to a repair facility to correct this fault. The warranty has been extended on some of these units to 7 years or 70,000 miles.
It is common for the fuel level sensor in the fuel tank read the fuel level incorrectly. The sensor must be replaced to correct the condition. Our technicians recommend having the complete fuel pump module replaced on high mileage vehicles.
The daytime running lights are prone to burning out. Our technicians tell us that the light sockets may show signs of heat damage but usually are OK. Always be sure to use the correct replacement bulb for the best life expectancy. The new bulb recommendation for 1999-2003 models is #4114K (trade number).

2003 Chevrolet Silverado 1500 Reviews
This is the best truck I have ever owned, 2003 SS with 191,518 miles and I'm now about to spend 2,000.00 in preventive maintenance just to be sure I can continue for another ten years!!!! I have always changed fluids when recommended and brake pads, thats it. The paint job is loosing its clear coat because I left it in the sun to long, other than that every single component work just fine however I don't abuse the truck but I do like to clean out the carbon every so often!
My 2003 silverado has been the worst vehicle I have owned. I had a 1993 and it was great, got 250,000 miles before engine went out on it shouaced of dropped a new engine in it instead of buying yhe 2003 model. Replaced brakes recently had to replace all four because of a recall on the brake system. Speedometer stopped working at about 100,000 miles, $600 dollars to fix. Fuel pump replaced $1000 dollars, bottom gasket on engine quote to replace $600 dollars. Now you now what I meant when I say worst truck or car I have ever had.
Big step up from my ford ranger! great fuel miliage, done a few modifications but on the highway i can get upwords to 21 mpg
I have the GMC version of this,they are exactly the same truck except for trim, I know,because I watched them go down the line for 22 years at Ft.Wayne truck Assy. plant. I love this truck it has not been any trouble at all, I replaced the rear brakes at 84,000 miles and that is all I've done to it. When I wax it people have asked if it is only a couple years old, it is now 7 years old and I will keep it till it quits and then fix it,even if it needs a new engine at 250k miles. I will leave this truck to my son.
Very good truck! A few problems but nothing major.
