2003 Chevrolet Silverado Problems

What owners report

Owners of this model year most often write about brake problems, and the single most common theme is rusted steel brake lines that leak fluid and let the pedal drop to the floor, usually noticed during ordinary low-speed driving or when backing out of a driveway. A second cluster concerns the instrument panel and other electrical faults, and a third covers steering-column clunks and transmission complaints that were sometimes reported when the truck was nearly new. Most brake-line reports arrive at higher mileage, while steering and transmission complaints often appear well under 60,000 miles.

   Rusted brake lines leaking fluid, pedal to the floor

   • 206 complaints (30%)
   • median 76,388 mi at 9.9 yrs old (190 state mileage)
   • 10 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 20 quotes)
   • filed 2003–2016

   Complaints describe the brake pedal sinking all the way down with little or no stopping force, often during low-speed driving, backing out of a driveway, or slowing for a light. On inspection, owners and their mechanics find one or more steel brake lines rusted through, with fluid weeping or pooling under the truck; several report needing the emergency brake to stop. Repair usually means replacing all the lines at the owner's cost, and some owners say the dealer confirmed the corrosion but did not cover it. Mostly reported between roughly 70,000 and 140,000 miles, frequently on trucks driven in wet or road-salt conditions.

   What to check: Have a shop inspect the steel brake lines end to end, especially above the rear axle and under the driver's door; a pre-formed line kit is available per a service bulletin. Ask when the lines were last replaced and look for damp spots or heavy rust scale.

   “Complete brake failure due to corroded brake line. Fortunately, it occurred in a parking lot as I backed out of the spot. My investigation revealed thousands of others with the same problem. Hoping someone realizes that someone is going to die if this does not get resolved.”

   NHTSA complaint #10427001, filed 2011-09, 28,000 miles

   “While hard on the brakes to avoid a vehicle, my rear brake line burst, and I lost all brakes. Luckily I was able to use the emergency brake to come to a stop. Now I have a $400.00 bill to replace rusted brake lines, that should have never rusted in the first place.”

   Brakes

   Antilock brakes activating at low speed or brakes not

   • 181 complaints (26%)
   • median 67,100 mi at 9.4 yrs old (164 state mileage)
   • 7 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 18 quotes)
   • filed 2003–2016

   Complaints describe the antilock system pulsing or releasing at walking pace, such as rolling up to a stop or turning into a driveway, which owners say lengthened stopping distance. Others report rotors rusting and pitting badly, uneven rear pad wear, or the parking brake assembly seizing so a rotor had to be cut off. Some owners had a hydro-boost relief valve replaced after the pedal moved on its own. Scattered from a few thousand miles to about 55,000 miles, often on trucks used in wet or winter conditions.

   Recall 04V045000Recall 05V1610002 related service bulletins

   What to check: Test the brakes at very low speed on a quiet street and feel for pulsing or a pedal that sinks; check the rotors for pitting and ask whether the hydro-boost unit or parking brake hardware has been serviced.

   “I purchased a 2003 chevy Silverado z-71 for my job which requires many miles. The right rear inside brake pad wears faster than any of the others. I had to replace it before 30,000 miles or it would cost me a new rotor. It is my understanding that this is a recurring problem on all full size trucks.”

   NHTSA complaint #10047403, filed 2003-11, 29,500 miles

   “I am the owner of a 2003 Chevrolet Silverado with 43,000 miles. As a result of the rear rotors on the truck rusting and falling apart, I had to replace the rotors. Due to the poor design of the parking brake assembly, the passenger side rotor had to be cut off with a torch!.”

   Transmission and drivetrain

   Harsh or delayed transmission shifts and driveline noise

   • 65 complaints (9%)
   • median 7,255 mi at 1.2 yrs old (55 state mileage)
   • 7 mention a crash, fire or injury
   • filed 2002–2011

   Owners report the transmission banging into second gear, jerking on light acceleration, or a grinding noise, with dealers sometimes describing the behavior as normal. Others report delayed or no engagement into drive or reverse, a broken shift cable that let the truck roll, or repeat flexplate replacement; a few report a transmission replaced under low mileage. Many reports come in under 15,000 miles, with others spread up to about 70,000 miles.

   5 related service bulletins

   What to check: Drive from a cold start and note any hard 1-2 shift, hesitation, or delay going into drive or reverse; check the transmission fluid and cooler lines for leaks and ask for service records.

   “I purchased a new Chevrolet Silverado truck on 8/15/2003. I drove it 15,000 miles and the transmission went out and was replaced. On another trip returning from denver to durango I was driving on a mountain road when the back wheels suddenly, without warning locked up. This caused the truck to go into an uncontrolled skid and I crashed into the side of the mountain. The truck bounced back into the road and almost forced other cars off the highway. The opposite side of the highway was very steep with no guardrail. …”

   NHTSA complaint #10088906, filed 2004-08, 23,000 miles

   “Had to replace a flexplat twice on 2003 Chevrolet 1500hd (4x4). First one at 43,000 miles, the second one was at 78,000 miles. Chevrolet would not help on either one. They also said they had no problems with it but the transmission shop found a service bulletin stating to use a new spacer if you do have problems.”

   Steering

   Steering clunk and play felt through the wheel

   • 58 complaints (8%)
   • median 20,000 mi at 2.8 yrs old (46 state mileage)
   • 1 mention a crash, fire or injury
   • filed 2003–2012

   Owners describe a clunk or pop felt and heard through the steering wheel at low-speed turns, along with looseness or wander in the front end. Several say the dealer replaced the intermediate steering shaft, and in some cases the noise returned within a few thousand miles; a service bulletin covers replacing the upper intermediate shaft. Reported from a few thousand miles up to about 50,000 miles in this sample.

   3 related service bulletins

   What to check: Turn the wheel lock to lock in a parking lot with the engine running and listen for clunks; ask whether the intermediate steering shaft has been replaced.

   “I along with 4 close friends each individually oun 2003 Chevrolet 2500hd pick up trucks. All of us have had a steering problem stemming from a steering component called the intermediate steering shaft all of my friends have had their shafts changed out under chevrolets factory warranty. I was not able to have mine covered because I am outside of the warranty milage, however I did have the problem diagnosed by my local dealer and was confirmed that the intermediate shaft was bad. …”

   NHTSA complaint #10112428, filed 2005-03, 48,000 miles

   “2003 Chevrolet Silverado with brake problems. Consumer states that the vehicle is on its second set of rotors and third set of pads. He believes that the 2003 and 2004 chevy Silverado should be included in the recall. The rotors were rusting and falling apart. The consumer also stated there was a constant noise coming from the steering column.”

   NHTSA complaint #10229549, filed 2008-05, 13,000 miles

Buying note. On this model year, pay for a brake-line inspection before anything else, since rusted lines are the most frequent complaint and the fix is inexpensive compared with the consequences. Then check the gauge cluster and steering feel on the test drive, and ask for service records on brake lines, the intermediate steering shaft, and transmission work.
