2004 Chevrolet Silverado Problems

What owners report

Owners of this model year most often describe brake problems, especially rusted steel brake lines that burst and send the pedal to the floor, usually on trucks with well over 60,000 miles. A second common theme is an erratic or stuck speedometer and other instrument cluster gauges, often reported below 60,000 miles and frequently handled by replacing the whole cluster.

1. 1
   Electrical system

   Speedometer stuck, erratic, or inoperative

   • 149 complaints (24%)
   • median 50,000 mi at 3.5 yrs old (134 state mileage)
   • 4 mention a crash, fire or injury
   • owner-quoted repair $500 (median of 19 quotes)
   • filed 2004–2016

   Owners report the speedometer needle sticking at a fixed speed, jumping to around 120 mph while parked, reading far below actual speed, or dropping to zero. Many say they had to estimate speed from the tachometer, and some mention a speeding ticket. Dealers typically replaced the entire instrument cluster rather than just the speedometer, and several owners say coverage ended before their mileage. Instrument cluster gauge service campaigns and a bulletin on speedometer needle accuracy apply to this era of trucks. Typically reported between about 28,000 and 100,000 miles, with many under 60,000 miles.

   What to check: Compare the speedometer against a GPS or scan tool reading at several speeds, including at a stop, and ask whether the cluster has been repaired or replaced.

   “My 2004 chevy truck was recalled because of instrument panel malfunctions. A recall has been issued; however, it seems to me that the plan to correct this has arbitrary recall parameters, ie 7 year/70,000 miles. My vehicle is 3 years old and has 96,000 miles and has experienced this malfunction. I did contact chevy but no concrete repair plan was established.”

   NHTSA complaint #10204798, filed 2007-10, 34,000 miles

   “I own a 2004 chevy Silverado z71 4x4 with 5.3l v8. At approximately 50k miles I started having erratic/incorrect speedometer readings and the speedometer sticks at varying locations on the panel. I must gage speed by using the tachometer. I haven't attempted to correct the problem yet as the cost will be 500.00 plus.”

   Brakes

   Rusted brake lines bursting, pedal to floor

   • 161 complaints (26%)
   • median 80,170 mi at 9.8 yrs old (146 state mileage)
   • 20 mention a crash, fire or injury
   • owner-quoted repair $1,000 (median of 18 quotes)
   • filed 2004–2016

   Complaints describe the brake pedal sinking to the floor, sometimes while backing out of a driveway or slowing for a stop, with brake fluid found leaking from a line under the driver-side floor. On inspection, owners say the steel lines were heavily rusted, and shops or dealers told them the lines needed to be replaced, sometimes quoting several hundred dollars for the set. Several owners note the truck was garage kept and otherwise well maintained. A pre-formed brake pipe repair kit is mentioned in one service bulletin. Mostly reported between roughly 80,000 and 190,000 miles, often on older trucks used in cold, road-salt climates.

   What to check: Have the brake lines inspected from front to rear for rust and seepage, especially along the frame rail under the driver's side, and ask whether any lines or the Hydro-Boost have already been replaced.

   “I was in stop and go traffic for about 3mi. When the car in front of me stopped, when I applied the brakes the peddle went to the floor and I hit the car in front of me on the rear bumper. Thank goodness I was moving very slowly when I hit him and there was now damage to either vehicle. I pulled off the road and looked under my truck and noticed a pool of brake fluid on the ground. …”

   NHTSA complaint #10523977, filed 2013-07, 76,481 miles

   “I was backing out of my driveway and a brake line blew. Lucky it happened in the driveway and not coming down a hill. I had to have the truck towed to a repair shop and they said all the lines need to be replaced due to rust. The cost to replace the lines is around $950.”

3. 3
   Transmission and drivetrain

   Hard or delayed transmission engagement and harsh shifts

   • 71 complaints (11%)
   • median 29,275 mi at 2.5 yrs old (58 state mileage)
   • 3 mention a crash, fire or injury
   • filed 2003–2015

   Owners describe the transmission slipping, hesitating before catching gear, thumping or jerking on the 1-2 shift, and sometimes not engaging drive or reverse. One complaint describes the column shifter showing the wrong gear and the truck rolling when the owner expected park. Dealers in some cases applied a retrofit kit or told owners no fault could be found, and several bulletins address no or delayed engagement and diagnostic codes for these transmissions. Mostly reported at low mileage, from under 10,000 to about 50,000 miles.

   4 related service bulletins

   What to check: Test drive from a cold start and check the 1-2 shift and engagement into drive and reverse, confirm the shifter detents firmly in each position, and ask for transmission service records.

   “After towing a trailer and putting the vehicle in reverse vehicle jumped and tore a piece of rubber out of the tire. Dealer stated that the vehicle was repaired. However, the transmission jumped from second gear to reverse without warning. Consumer stated that the dealer said there was no code set, and to continue driving, but the consumer refused.”

   NHTSA complaint #10089305, filed 2004-08, 1,056 miles

   “Dt: 2004 Chevrolet Silverado. The consumer states that the transmission has a slip in it and it stalls. The dealership insists there is nothing wrong with the vehicle and it cannot be fixed. The vehicle hesitates and then clangs when it catches into gear. The manufacturer stated they need to speak with the dealership before they could make a decision. The problem has been occurring since approximately february 2005. This does not happen all of the time.”

   Air bags

   Air bag warning light or unexpected deployment

   • 34 complaints (5%)
   • median 30,000 mi at 1.8 yrs old (30 state mileage)
   • 24 mention a crash, fire or injury
   • owner-quoted repair $800 (median of 5 quotes)
   • filed 2004–2022

   Complaints describe the air bag warning light coming on intermittently and then staying on, with some dealers unable to find a fault or quoting high diagnostic and repair costs. Others report air bags failing to deploy in a collision, and one owner reports the steering wheel air bag deploying while the truck was parked and the key was turned. A recall covers cloth-seat trucks later reupholstered with aftermarket leather covers, which can affect the passenger sensing system. Reported from a few thousand to over 170,000 miles, with several between about 30,000 and 40,000 miles.

   Recall 06V417000

   What to check: Ask whether the truck still has original cloth seats or was reupholstered, confirm the air bag recall was performed if it applies, and check that the air bag light comes on and then goes out at startup.

   “While driving the air bag light came on , and the computer read out, saying servicing air bag. The consumer took vehicle to the dealer, they placed it on the computer and stated it showed no defects, and warranty has expired.”

   NHTSA complaint #10107120, filed 2005-02, 37,600 miles

   “Air bag warning light occasionally started coming on. Took truck to several independent svc places. They said do not have computer reader for airbags. Light started staying on constantly. Took truck to dealers and they said because of liability, the diagnostics are $900 and could run another $1500 or more to fix problem. And, they wanted to keep truck. Truck is used daily for short runs and has a bunch of equipment on it that would have to be removed in order to leave it somewhere. …”

Buying note. Check the brake lines and steering assist carefully on a truck of this age, since those are the failures owners describe most and they cost real money to correct. Confirm any instrument cluster or air bag recalls and service campaigns were completed and keep up with fluid and line maintenance.
