What owners report
Owners of this model year most often describe instrument cluster problems — speedometer and fuel gauge readings that jump, stick or stop working — and brake problems where the pedal goes to the floor, usually traced to corroded steel brake lines. Both tend to appear at moderate mileage rather than at delivery, and complaints also mention airbag warning lights, transmission slipping and fuel leaks at a full tank.
- Electrical system
Speedometer and gauge cluster malfunctions
- 59 complaints (36%)
- median 52,500 mi at 4.0 yrs old (50 state mileage)
- 1 mention a crash, fire or injury
- owner-quoted repair $634 (median of 8 quotes)
- filed 2006–2015
Complaints describe the speedometer reading zero while driving, jumping to exaggerated speeds, sticking, or jittering, with the tachometer and volt gauge misbehaving at the same time. Several owners say the dealer diagnosed a failed instrument panel cluster, and some report the manufacturer covered the part but not installation. A few mention the fuel gauge fluctuating or showing empty right after filling up. Reported from about 40,000 to 110,000 miles, and several say it appeared on the first drive of the morning or was intermittent.
What to check: With the engine running, watch the speedometer and fuel gauge for sticking or drift, and ask whether the cluster was ever repaired or replaced. A service bulletin describes a dealer check for gauge needle accuracy on these vehicles.
2 excerpts from owner complaints in NHTSA records
“My 2004 chevy Avalanche's speedometer has been sticking on 65 for a week now. Today it completely went out and stays on 0 MPH now. I have no idea what I am going to do now other than not drive it until I can afford to repair it. Every bit of research I have done on this matter shows that thousands of other people are having the same problem. I baby my truck and take excellent care of it. It has 66,000 miles on it.”
NHTSA complaint #10207047, filed 2007-10, 66,550 miles“While driving or in park the tachometer sticks as does the speedometer. This has lasted from minutes to days. The vehicle appears to run properly, however, I am very leery of my safety and the safety of my children when they are in control of the vehicle.”
NHTSA complaint #10716262, filed 2015-05, 73,245 miles - Brakes
Brake pedal sinks to floor from rusted brake lines
- 35 complaints (21%)
- median 78,803 mi at 9.5 yrs old (35 state mileage)
- 2 mention a crash, fire or injury
- filed 2005–2021
Owners describe the brake pedal dropping to the floor with little or no stopping power, often while backing out of a driveway or slowing for a light, with brake fluid visible on the ground afterward. In many cases the mechanic found metal brake lines rusted through and replaced them; dealers also replaced lines in some complaints. Separately, some describe the ABS activating at low-speed stops on dry pavement, with the service brakes light coming on. Mostly reported between roughly 40,000 and 140,000 miles, and often in vehicles that had seen winter road use.
Recall 05V043000Recall 04V0450003 related service bulletins
What to check: Have the steel brake lines along the frame and under the driver's side inspected for rust, and ask about any brake line or hydro-boost replacement. A service bulletin notes that pre-formed brake pipes are available for this generation of truck.
2 excerpts from owner complaints in NHTSA records
“Started my Chevrolet, started backing up down an incline of my driveway, service brakes indicator illuminated. Brake pedal sank to the floor. No brakes. Opened hood and the front left wheel brake line (cheap steel) was shooting brake fluid everywhere and all over the engine. It's going to a Chevrolet dealership tomorrow for repairs.”
NHTSA complaint #10503229, filed 2013-03, 76,912 miles“The brake line burst as I was shifting into drive could not stop vehicle, shifted it into park and was able to stop before hitting someone. Why are these lines not made of stainless steel? Better yet why is this agency not doing anything about this? They jump all over a key switch that may cause a problem but do nothing for something as important as be able to safely stop our vehicles.”
NHTSA complaint #10731835, filed 2015-07, 189,000 miles - Transmission and drivetrain
Transmission slipping, clunking or loss of drive
- 10 complaints (6%)
- median 54,062 mi at 5.3 yrs old (10 state mileage)
- filed 2004–2014
Complaints describe the transmission quitting while driving, not engaging reverse, slipping in automatic mode, or producing a clunking and grinding sound between gears. One owner reported a burned clutch diagnosed at a dealer; others describe chatter and shudder on turns with the locking differential. Some complaints say fluid leaked from the transmission cooler lines. Reported from around 20,000 to 90,000 miles, with several failures described at low mileage.
What to check: Test drive through every gear, listen for clunks or whine when shifting, and check the transmission cooler lines and fluid for leaks.
2 excerpts from owner complaints in NHTSA records
“I have problem with the brake system, and the transmission fluid came out from the from front passenger side. I took it to the chevy dealer, but I was told that the transmission clutch was burned out, maybe it an defected transmission or recall, im not sure, but I do know that the transmission and the brake system are not in safe conditions, nor workable. Not to mention the cracking noise in the front of the suspension, while turning.”
NHTSA complaint #10241413, filed 2008-09, 69,124 miles“While driving on freeway vehicle was revving up, immediately exited freeway and found transmission was gone, vehicle would not go in reverse, did drive in neutral. Vehicle has only 30k miles. Took vehicle to transmission mechanic stated the chevy Avalanche and denali are known for this, and feels this is a factory defect. His vehicle too went out at 20k miles. My cousin transmission too went out at 50k miles, would like to have dealer repair my vehicle. …”
NHTSA complaint #10269969, filed 2009-05, 30,000 miles - Fuel system
Fuel smell and leaks at the fuel tank
- 6 complaints (4%)
- median 66,250 mi at 9.0 yrs old (6 state mileage, few)
- filed 2005–2015
Owners report a strong gasoline smell after filling the tank, with fuel seen dripping from the top of the tank when full. In several complaints the dealer found the fuel pump module locking ring rusted and the top of the module rusted through, requiring the tank to be dropped for replacement. Another complaint describes no in-line fuel filter and a contaminated fuel system around 60,000 miles. Mostly reported between about 48,000 and 145,000 miles, typically right after refueling to full.
What to check: Fill the tank fully and look and smell for fuel around the tank and under the driver's side; ask whether the fuel pump module or locking ring has been replaced.
2 excerpts from owner complaints in NHTSA records
“I started to notice a strong gas smell whenever I fully filled the gas tank. The odor would disappear after the needle moved off the full mark. Later investigation showed gas droplets coming down from the top of the fuel tank when it was full or near full. Subsequent examination by GM dealership revealed rusted out fuel module (pump/sender unit) locking ring and rust hole in top of fuel module. Examination required gas tank to be removed. Labor and fuel module replacement cost = $1000.00. …”

NHTSA complaint #10809055, filed 2015-12, 145,000 miles
Buying note. Check the brake lines for rust and the gauge cluster and warning lights for proper operation before buying, since these are the most frequently described concerns. Service records showing brake line, cluster or fuel module work are worth asking about.

Example complaints
Electrical system: “I did an internet search to see what causes a speedometer to go out and to my surprise there are many people who have had their speedometer to go out on this model vehicle. Most people experienced this problem around 30,000 miles. It would benefit consumers if this problem were addressed by the manufacturer.”
NHTSA complaint #10492956, filed 2013-01, 103,000 milesBrakes: “My son was going to the store and when he applied the brake the pedal went to the floor and he had no brakes.
