2002 Chevrolet Silverado 2500 Problems

What owners report

Owners of this model year most often report brake problems, and the dominant theme in the complaints is rusted-through steel brake lines that suddenly lose pedal and pressure, sometimes while driving. A second, smaller group describes the anti-lock system activating at low speed on dry pavement and lengthening stopping distance. Engine concerns center on random stalling and no-starts in 8.1L trucks, often traced by dealers to the crankshaft position sensor.

1. 1
   Brakes

   Rusted brake lines with sudden pedal loss

   • 190 complaints (54%)
   • median 85,379 mi at 10.0 yrs old (177 state mileage)
   • 17 mention a crash, fire or injury
   • owner-quoted repair $1,075 (median of 16 quotes)
   • filed 2002–2025

   Complaints describe the brake pedal going to the floor with little or no warning, often after a hard stop or while pulling into a parking spot, followed by brake fluid visible under the truck or near the frame. Shops and dealers reportedly found hard lines corroded through and recommended replacing some or all of them, frequently in stainless steel. Several owners mention that the truck had been driven in road-salt conditions and that other lines (fuel, cooler lines) showed similar corrosion. Spread across the sample from roughly 40,000 to over 200,000 miles, with many reports in the 60,000-150,000 mile range and several noting winter road salt.

   What to check: Have the hard brake lines inspected along their full length, especially above the rear axle and along the frame, and ask whether any have been replaced. A pre-purchase inspection focused on line condition is worthwhile on a truck that has seen salted roads.

   2 excerpts from owner complaints in NHTSA records

   “A brake line rusted through in the front of the truck. After looking under the truck, I found that all the brake lines are severely rusted and look as if they will fail at any time. All brake lines will have to be replaced before this vehicle is safe to drive again. After checking on the web I have found thousands of other complaints and still there is no GM recall.”

   NHTSA complaint #10430324, filed 2011-10, 63,534 miles

   “Brake line failure on my 2002 Chevrolet silverado 2500hd. I was very fortunate that the line broke at home while I was parking my trailer. Apparently there is a major problem with the steel lines rusting out prematurely. If you go on the web and look up brake line failure for this year vehicle, you will find many.”

   Engine

   Random engine stall or no-start (8.1L)

   • 60 complaints (17%)
   • median 91,268 mi at 8.6 yrs old (55 state mileage)
   • 2 mention a crash, fire or injury
   • owner-quoted repair $1,425 (median of 6 quotes)
   • filed 2002–2021

   Complaints describe the engine shutting off without warning at highway or in-town speeds, sometimes restarting after a few minutes and sometimes requiring a long crank. Some trucks also fail to start when cold. Dealers in several reports diagnosed a faulty crankshaft position sensor, and one owner noted a repeated failure of the replacement part; another said diagnostics initially showed nothing. Reported from roughly 32,000 to 145,000 miles, occurring at any speed with no pattern to the shutdowns.

   What to check: Ask whether the crankshaft position sensor has been replaced and keep service records; if a truck stalls on a test drive or cranks unusually long, have it scanned for stored codes before buying.

   2 excerpts from owner complaints in NHTSA records

   “While driving under normal highway conditions, the engine has stalled three times in two weeks. This causes a loss of power steering and power brakes. At this point I have been able to safely pull off of the road, as it has not occurred during congested traffic. While searching the database I found similar failures of 2001 8.1l engines that were recalled to replace the crankshaft position sensor.”

   NHTSA complaint #10223047, filed 2008-04, 68,000 miles

   “I have a 2002 chevy SILVERADO 2500 hd 4x5 8.1, I have replaced the crankshaft position sensor a year ago and now I am getting the error code again stating its is bad again. This is not a cheap part and very difficult to change, what is the problem.”

   Brakes

   ABS activates at low speed on dry pavement

   • 63 complaints (18%)
   • median 80,000 mi at 8.7 yrs old (61 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $1,500 (median of 5 quotes)
   • filed 2005–2021

   Owners describe the anti-lock system kicking in during normal low-speed braking on dry roads, producing a pulsing pedal and longer stopping distance. Some say dealers or independent shops pointed to wheel speed sensors needing replacement or cleaning, while others report the problem returned or was never resolved. Several complaints reference a past antilock brake campaign and note their vehicle was excluded by VIN or by state. Mostly reported between about 40,000 and 140,000 miles, during ordinary low-speed stops.

   2 related service bulletins

   What to check: Test the brakes at walking speed on dry pavement and feel for pulsing or a pedal that drops; ask whether wheel speed sensors or the hydro-boost unit have been serviced. A service bulletin describes replacing the hydro-boost when the pedal moves or applies on its own at full turns.

   “Antilock brakes are activated every time I use my brakes. My truck needs longer stopping distances to come to a complete stop. I almost got into a major accident. There is a recall on 1999-2002 chevy silverado anti-lock brakes in my state of michigan but I have not received a notice and GM says I will not get one. I own a 2002 silverado.”

   NHTSA complaint #10167870, filed 2006-09, 34,000 miles

   “Anti lock brakes activate at low speeds on dry roads and increase stopping distances. This issue is addressed by recall 05068a and 05v379000. My VIN is listed however the Chevrolet dealer that I went to advised that it is not covered under the recall. I am concerned that an accident will result from this defect.”

   NHTSA complaint #10157847, filed 2006-05, 42,000 miles

Buying note. Inspect the brake lines closely and get any ABS behavior checked before buying, since those are the concerns owners raise most. On 8.1L trucks, ask about the crankshaft position sensor and any stalling history, and on diesels check the oil for a fuel smell.

Summary written with AI from a sample of 60 NHTSA complaints for this model year (picked at random, with complaints that state a mileage and recent ones taken first), then checked automatically against the source records. Where a problem shows a complaint count, every complaint for this model year was matched with fixed keyword rules (written with AI and tested against the sample), and the mileage, age and repair figures are calculated from those complaints; owners' figures are as stated, not verified. Other counts refer to the sample.
