2003 Chevrolet Silverado 1500 HD

No clear pattern

0% of complaints about the 2003 Chevrolet Silverado 1500 HD arrived in its first year of service. That is an unusual figure for a 2003 vehicle, but with only 124 complaints on record the sample is too small to call it a pattern — the margin of error covers the range where ordinary vehicles sit. The figures below are reported without a verdict. The most-reported system is electrical system (30 complaints), typically at 5.3 yr or about 84,000 miles.

Complaints: 124
Median age at failure: 8.4 yr
Median mileage: 86,800 n=113
Crash / fire / tow: 5.6% of reports
Safety recalls: 0

Electrical system 45,000 mi 2.7 yr in service

SPEEDOMETER STOP FUNCTIONING AND DOESN'T ACCURATELY REFLECT THE VEHICLE'S SPEED. THE SPEEDOMETER IS STUCK AT 120+ MPH. I TOOK THE VEHICLE INTO THE GM DEALER AND THEY SAID THAT THE ENTIRE ELECTRONIC INSTRUMENT PANEL MUST BE REPLACED AT A COST OF OVER $500. AFTER SEARCHING THE INTERNET FORUMS IT APPEARS TO BE A WIDESPREAD PROBLEM. SEE THIS WEBSITE HTTP://WWW.TOPIX.NET/FORUM/AUTOS/CHEVROLET-SILVERADO-1500/TR5QAB2MN19BL1D2J. THIS POSES A SAFETY HAZARD BECAUSE THE DRIVER DOES NOT KNOW THE SPEED OF THE VEHICLE. *NM

Electrical system 40,000 mi 4.3 yr in service

I HAVE A 2003 CHEVROLET P/U AND THE SPEEDOMETER WORKS VERY ERRATICALLY. IT USUALLY REGISTERS A MUCH FASTER SPEED THAN I AN TRAVELING. WHEN I AM STOPPED IT WILL SHOW A SPEED OF FORTY OR FIFTY MPH. THIS PROBLEM SEEMS TO COME AND GO. IT IS VERY UNSAFE TO NOT KNOW YOUR SPEED. I KNOW MANY OTHER GM AND CHEVROLET VEHICLES OF THIS YEAR EXPERIENCE THE SAME PROBLEM. *NM

Electrical system mileage not reported 4.3 yr in service

I HAVE A 2003 CHEVY SILVERADO 1500 HD WITH APPROX 55,000 MILES ON IT. WITHOUT NOTICE THE SPEEDOMETER FAILED TO WORK (NEEDLE IS FIXED BETWEEN 60-120 MPH). AFTER RESEARCHING THIS PROBLEM ON THE INTERNET, I DISCOVERED THAT MANY COMPLAINTS HAVE BEEN LEVIED (IN AT LEAST AN INFORMAL SETTING). *NM

Service brakes, hydraulic 103,389 mi 7.6 yr in service

BRAKE LINES HAVE ROTTEN OUT IN 6 YRS WITH OUT WARNING ,AND COULD HAVE CAUSED ACCIDENT, IF I WAS IN TRAFFIC LOW POWER IN BOOSTER. *TR

How to read this

This is what owners reported, not a reliability rating. People file with NHTSA about alarming failures, not routine ones, and complaint volume tracks how many cars were sold.
Failure ages come from the incident date on each complaint, populated on about 83% of records. Mileage is shown where reported — NHTSA’s 2021 system change cut mileage capture to roughly 15%, so it thins out sharply after MY2020.
Every rank compares this vehicle only against others of the same model year. A 2025 car has not had time to accumulate five-year failures, so comparing early-failure share across years is meaningless.
Fourteen make-months distorted by media storms and mass recalls — Toyota in February 2010 ran 11× normal volume across 33 models — are excluded.
Recalls are manufacturer actions and authoritative; complaints are not. A recall listed here may already have been performed on any individual car. Check a specific VIN at nhtsa.gov/recalls.
