2003 Chevrolet S10 Problems

What owners report

Owners of the 2003 Chevrolet S10 most often write about brakes, and the recurring theme is corroded steel brake lines that give out after years of rust, often with little or no warning. A second cluster of complaints covers body hardware — door handles, latches and the spare-tire cable under the bed — which owners describe as breaking or rusting through in ordinary use. Air bag warning lights and non-deployment in crashes, plus instrument cluster and wiper electrical faults, round out the more common reports.

1. 1
   Air bags

   Air bag warning light on and no deployment in crashes

   • 15 complaints (8%)
   • median 87,524 mi at 12.3 yrs old (12 state mileage)
   • 9 mention a crash, fire or injury
   • filed 2003–2021

   Owners report the air bag warning light staying lit or coming on intermittently, sometimes more often in warm weather, and say dealers gave only partial diagnoses such as a possible sensor or steering-wheel connection. Several complaints describe front-end collisions in which neither the air bags nor, in some cases, the seat belt pretensioners deployed, and one owner reports a diagnostic code for an air bag impact sensor. Owners commonly note that no recall covered the condition. Reported anywhere from about 23,000 to 200,000 miles, with several at higher mileage on trucks well past ten years old.

   Recall 04V132000

   What to check: Check that the air bag light performs its self-test and goes out after startup, and ask for any stored air bag codes to be scanned before purchase.

   2 excerpts from owner complaints in NHTSA records

   “At 37000 miles my s-10 pickup started displaying a airbag warning light on the dash. The light is not constant and appears more on warm days. Being concerned I researched this problem om the internet. I found that this is a very common problem with this model of GM vehicle. I contacted GM to see if this was a warranty or recall issue and they stated no. With the air bag light on it is my understanding that the airbags will not deploy as long as the warning light is being displayed. This is a safety issue that needs to be corrected. …”

   NHTSA complaint #10593848, filed 2014-05, 37,000 miles

   “I was going through a green light at an intersection,when another vehicle ran the red light at a high speed. The vehicle hit the front center of my bumper and the airbags did not deploy and the seat belts did not hold. I was headed south,and the other vehicle was headed west,when it hit me. It turned me into the westward direction. When I came to, my head was hanging out the window and my son(who was in the passengers seat )was on top of me. He was thrown across the console,our seat belts did not hold. I was transported to the er by ambulance. …”

   Brakes

   Corroded brake lines failing and leaking fluid

   • 14 complaints (8%)
   • median 65,500 mi at 9.8 yrs old (13 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2007–2021

   Owners describe the brake pedal sinking toward the floor or needing repeated pumping, with fluid loss under the truck. Mechanics and owners who inspected the lines found heavy rust, typically along the hard lines near the fuel tank or along the frame, and in several cases more than one line needed replacement. Some report the lines gave way while driving at low speed or coming to a stop; a few also mention rust on rotors and lines found at inspection. Mostly reported from roughly 42,000 to 140,000 miles, on trucks many years old and in rust-belt conditions.

   What to check: Have a shop inspect the full length of the steel brake lines, especially above the fuel tank and along the frame, and ask whether any lines or rotors have been replaced. Watch for a brake pedal that feels soft or slowly sinks while held.

   “I applied the brakes on entering my driveway. The pedal went nearly to the floor. A pool of brake fluid formed on the driveway under the driver's side about the middle of the truck. Investigation showed a corroded and burst brake pipe just in front of the fuel tank.”

   NHTSA complaint #10438890, filed 2011-12, 47,163 miles

   “My wife was picking up our 2 year old and 6 year old granddaughters from their home and bringing them to our house to babysit them. Traveling at 35-45 MPH she depressed the brake pedal to stop and the pedal slowly went to the floorboard. She finally made it home and she told me about it. I looked under the vehicle and noticed something leaking from the under carriage. I jacked the vehicle up and inspected the brake lines and discovered that the brake lines were rusted and one had cracked. …”

   Body and structure

   Third door and tailgate hardware breaking

   • 31 complaints (17%)
   • median 43,306 mi at 4.3 yrs old (19 state mileage)
   • 2 mention a crash, fire or injury
   • filed 2003–2012

   Owners of extended-cab trucks describe the plastic handle on the third door breaking, sometimes more than once and sometimes within days of replacement, leaving the door difficult or impossible to open from outside. Others report tailgate slack, a tailgate coming loose while driving, and worn door hinge bushings that make doors hard to open and close. Several owners say dealers replaced the parts under warranty but the same part failed again. Reported from about 10,500 to 46,000 miles, often on trucks only a few years old.

   2 related service bulletins

   What to check: Open and close the third door and tailgate several times and look at the handle and latch for cracks or play; check the tailgate cables for slack and the hinge bushings for wear.

   2 excerpts from owner complaints in NHTSA records

   “Tailgate fell off while driving. One side stayed attatched causing tailgate to drag. Also, engine makes high pitch squealing noise between 4000-4500 rpms. Also 5th gear went out while driving down the freeway. Have had several friends that own the same vehicle have transmission problems like this. Also, molding around front windshield likes to melt.”

   NHTSA complaint #10039598, filed 2003-09, 7,300 miles

   “Opening third door at food store. The third door handle broke. Unable to open door. Replaced handle and it broke also. Broken part is available. Plastic squeeze handle broke.”

   Tires

   Spare tire cable rusting through and dropping the tire

   • 8 complaints (4%)
   • median 70,000 mi at 10.4 yrs old (8 state mileage, few)
   • filed 2008–2014

   Owners describe hearing a clank or feeling a jolt and then seeing the spare tire in the road behind them, with the cable at the hoist found broken or rusted through at the stop. In each case the tire dropped in ordinary driving rather than after an impact. Owners repaired the cable themselves or replaced the hoist assembly. Reported from about 31,000 to 190,000 miles on older trucks exposed to road salt and weather.

   What to check: Lower the spare and inspect the hoist cable and cable stop for rust or fraying; a cable that looks pitted or thin is worth replacing before it fails.

   “While driving down the road (luckily not fast and without traffic!!) . I felt a slight bump. First thought was I hit a pothole or ran over something in the road in spite of the fact I did not see anything. Naturally, I checked the rearview mirror and to my surprise, saw a wheel in the middle of the street which I know I did not run over- next thought was its from my truck! Thank god I was not on the highway !! . …”

   NHTSA complaint #10568294, filed 2014-03, 70,000 miles

   “I was pulling out from an intersection when something jolted the vehicle and made a noise like something hit the truck. Looking back in the rear view mirror, it was noticed that the spare tire was lying in the road and the car behind me almost hit it. I went back and picked up the tire. After returning home my father inspected the truck and said the cable had broken where the spare tire mount holds the tire up under the truck bed. …”

   Visibility (wipers, defrost, mirrors)

   Windshield wipers stopping or running continuously

   Mentioned in 4 of 60 sampled complaints

   Owners report wipers that quit mid-stroke, refuse to turn on at the selected speed, or keep wiping after being switched off, sometimes with washer fluid that will not shut off until the engine is restarted. Several say the failure shows up in heavy rain and requires stopping and rapping the wiper motor to get moving again. One owner traced it to cracked solder joints on the wiper control board; another had the switch replaced more than once without a lasting fix. Reported from about 42,000 to 167,000 miles across trucks of varying age, often noticed in rain or on the highway.

   What to check: Test every wiper speed and the delay setting, including a single wipe and the washer, and let them run for several minutes to see whether they stop or stall.

   2 excerpts from owner complaints in NHTSA records

   “This is second vehicle of previous complaint. We have two 2003 Chevrolet s-10s where the wipers stop working during rain. In most cases during heavy rains while driving on highways and interstates. Vehicle has to be pulled over and the hood has to be raised to tap the motor to be able to continue.”

   NHTSA complaint #11221496, filed 2019-06, 167,000 miles

   “Windshield wipers stopped working. Checked all the fuses and found no problems. Windshield wipers well at times and stopped at very bad times; heavy rain times. After several days of chasing wires I found the micro soldering on the wipers computer board cracked in several places. The wire harness vibrated on it and the engine overheated it. The entire system needs a better attachment for the wire harness and some form of insulation from the engine.”

Buying note. A 2003 S10 is an old truck, so condition matters more than mileage: have the brake lines and spare-tire hoist cable checked closely, test the wipers and door hardware, and confirm the air bag light behaves normally before buying.
