Other speed control problem on the 2003 Chevrolet Silverado 2500

Only 5 reports for this mode came with an odometer reading, which is too few for percentiles to mean anything. The page is here because someone linked to it; treat the figures as anecdotes, and see the full report for this year instead.

When other speed control problem gets reported

There are 8 reports of other speed control problem on the 2003 Chevrolet Silverado 2500, 5 with a mileage attached. That is too few to place the failure on the odometer with any confidence.

A part like this is normally expected to survive 78,000 miles. It is the 18th most-reported problem on this model year.

The whole distribution

Percentiles of the 5 odometer readings owners gave.
10th25thMedian 75th90th
— — 110,000 miles — —

Read the 10th percentile as “one report in ten arrived this early”. Exact figures are shown in this table because it is the table of record; everywhere else on the site they are rounded to the precision the sample can carry.

What a percentile can and cannot tell you here

These five numbers describe the readings owners gave, in order. The median is the middle one: half the reports arrived below it. The 10th and 90th are the edges of the bulk of the distribution, and the distance between them is the part worth reading. A tight spread — say 70,000 to 95,000 miles — points at something that wears out on a schedule, and the schedule is knowable. A wide one, 20,000 to 190,000, points at a fault that hits some cars and never troubles others, which means the mileage on the listing in front of you tells you very little about your odds.

What these figures are not is a survival curve. Every reading here comes from a car whose owner filed a complaint, so the sample contains only failures: it cannot say what share of the fleet made it past 150,000 miles untouched, because those owners had nothing to report. Nor is the mileage the moment of failure — it is the odometer reading as recalled at the time of filing, which may be weeks later and is sometimes rounded to the nearest ten thousand by the person typing it.

Percentiles are shown at all only once 8 readings exist for the vehicle and mode. Below that the middle of a handful of numbers is noise wearing a decimal point, so the figures are withheld rather than dressed up.

What happens, and what it costs

Putting it right typically runs $250–$2,000 at an independent US shop. That range is an editorial estimate held in this site's failure-mode catalogue, not a figure from NHTSA, and it is a repair cost rather than a diagnosis cost.

This mode is classified as critical, which means a failure can leave the car unable to stop, steer, or stay out of the way of traffic. It is weighted accordingly in the risk score.

The same failure on other years

The same failure is reported on 6 model years of this car. It shows up earliest on the 2009, at a median of 1,600 miles, and latest on the 2003 at 110,000 miles.

By volume the 2003 is the worst of them, which makes this a problem of this specific year rather than of the model as a whole.

If one year stands out to the left, that is the year to avoid; if the whole line sits at a similar mileage, this is wear rather than a defect in one production run.

What owners wrote

Verbatim from NHTSA complaint narratives, trimmed for length. The mileage is the one the owner gave.

Dt: 2003 chevrolet 2500 hd truck experienced an engine power reduction. The vehicle operated at a reduced speed. It goes at a crawl. This occurred at speeds of 40-50 MPH in the middle of traffic. Has to coast over to the side of the road, on average about 10-15 seconds after cutting off then the engine restarted. This usually happened after vehicle has not run for an extended period of time such as being parked overnight. Took to a dealer, who replaced the accelerator pedal that ran by wire not cable. This was electric and computerized and some sort of signal went through the accelerator pedal and caused this failure. The vehicle will idle, but lost power. This has been a problem for the last 3 months. The problem recurred even after the replacement of 2 accelerator pedals. *ak

Speedometer began to jump around and it was impossible to tell how fast I was going. Dealer told me it wasn't a recall issue, but too many gm owners were having the same problems.*ak

Tl* the contact owns a 2003 chevrolet silverado 2500 heavy duty. While attempting to accelerate from a traffic stop, the accelerator pedal fell into the floorboard much farther than normal however; the vehicle would not accelerate over 25 MPH. The reduced power warning light was illuminated and the contact moved the vehicle off the roadway. The contact shut off and restarted the vehicle. The vehicle resumed normal operation. The failure recurred two additional times. The dealer re-routed the inside engine harness yet the failure continued to recur intermittently. The vehicle was taken back to the dealer where they performed an engine relearn service. The failure persisted. The failure mileage was 110,000 and the current mileage was 117,000.

How far this goes

This page is kept out of search results because 8 reports is not enough to publish percentiles from. It stays reachable because somebody looking at this exact car would rather see the reports than be told there are none.

Complaints are voluntary, so 8 is a floor and not a count of affected cars. Mileages are typed in by owners and cluster on round numbers. And the mode itself is assigned by software reading the complaint text, which is reliable in bulk and fallible one report at a time.

Questions this page answers

At what mileage does other speed control problem happen on the 2003 Chevrolet Silverado 2500?

Across 5 owner reports that included an odometer reading, half were filed by 110,000 miles. A quarter were filed before — and a quarter after —. These are the mileages owners reported when they complained, not a prediction for any individual car.

How common is other speed control problem on the 2003 Chevrolet Silverado 2500?

8 reports have been filed with NHTSA, about 27 per 1,000 vehicles. Complaints are voluntary, so this is a floor rather than a count of affected cars.

What this is and is not. These are the mileages at which owners chose to complain to a federal agency, which is not the same as the mileage at which the part fails on every car. It skews toward failures that happened outside warranty, cost real money, or frightened someone. It is still the only public dataset that carries failure mileage at all, and the shape of a few hundred readings is informative even when a single one is not.
