2004 Chevrolet Avalanche 1500 problems
The Chevrolet Avalanche is a four-door, five- or six-passenger pickup truck that was manufactured by General Motors. The Avalanche was a hybrid between the Chevrolet Suburban SUV and the Chevrolet Silverado pickup truck, sharing the chassis with the Suburban. Unlike a typical pickup truck where the bed is mounted separately from the cab on the frame, the bed of the Avalanche was integrated with the cab body. It also featured a "midgate" behind the second row of seats that could be folded down, with the seats, to create a longer bed area. The Avalanche was produced across two generations starting in 2001 and ending in 2013.
Breaking with a long-standing tradition, the Avalanche was not available as a GMC, but only as a Chevrolet. Instead, Cadillac would sell a re-badged Avalanche; however, the midgate design would be adapted for use on the GMC Envoy XUV and Hummer H2 SUT.
First generation (2001–2006)
The Avalanche was launched in September 2001 as a 2002 model on the GMT800 platform. First year Avalanches featured light gray plastic body cladding, intended to provide visual distinction from the Suburban/Yukon XL. The Avalanche also gave the public an advance look at the next generation of front fascia designs for the entire GM line. A full-length chrome strip splits each lamp assembly and the grille, with a gold Chevrolet "bow tie" in the center. The hood and fenders featured aggressive folds, in contrast to the softer designs seen on other models built on the GMT800 platform.
Avalanche was nominated for the North American SUV of the Year award and was Motor Trend magazine's Truck of the Year for 2002.
The Avalanche was originally marketed as being able to "change from an SUV to a super SUV." This was made possible by a plastic cover and an exclusive "midgate," called the Convert-a-Cab system by GM, which could open and close. The midgate was a divider behind the second row of seats that could be folded down, with the seats, to create a longer bed area, or folded up to make a larger cab area. A similar midgate was found on the Cadillac Escalade EXT (a rebadged Avalanche), Hummer H2 SUT, and GMC Envoy XUV.
The truck was offered as a half-ton 1500 series with a Vortec 5.3L V8 producing 285 hp (216 kW) or as a three-quarter-ton 2500 series with a Vortec 8.1L V8 with 340 hp (253 kW) and the 4L85-E four-speed transmission. The base layout is rear-wheel drive, but there is an available with selectable high/low four-wheel drive. Avalanche 2500 models from 2004–2006 were exclusively available with four-wheel drive.
For those who planned to go off-road in their Avalanche, a Z71 Off-Road package was available that added features such as off-road suspension, GM's AutoTrac full-time push-button four-wheel-drive system, all-terrain P265/70R17 white-lettered Goodyear tires, seventeen-inch alloy wheels, leather seating surfaces with waterproof accents, front dual power bucket seats, cloth door panel inserts, GM's OnStar telematics system, all-weather rubber floor mats, Chevrolet bowtie emblems embedded into the backrests of the seats (for 2002 models), dual-zone automatic climate controls with rear HVAC vents and remote controls, remote radio controls with headphone jacks for two pairs of headphones, a security system, gray-finished side running boards, power-adjustable, heated side-view mirrors, SRS side impact airbags. Aside from these details, a Z71 Off-Road decal on the rear side panels identified an Avalanche equipped with this package. Full leather seating surfaces were an available option, also removing the cloth door panel inserts, and also added heated front seats.
For those who preferred the styling of the Z71 Off-Road package but did not plan to take their Avalanche off-road, a Z66 Premium On-Road package was also available. The Z66 On-Road package featured all the equipment that the Z71 Off-Road package offered but replaced the off-road suspension with sport on-road suspension and did not offer four-wheel drive. Aside from these details, a Z66 On-Road sticker on the rear side panels identified an Avalanche equipped with this package. As with the Z71 Off-Road package, full leather seating surfaces without the cloth accents were an available option, also removing the cloth door panel inserts, and also added heated front seats.
To further distinguish it from its Silverado siblings, the Avalanche was practically fully equipped and only came with bodyside cladding. The Avalanche included features such as 16-inch alloy wheels and tires (chromed steel on the 2500 model), an AM/FM stereo with single-disc CD player and six speakers, cloth seating surfaces, front bench seat with power front driver's seat, power windows, power door locks, keyless entry, full instrumentation, dual front airbags, and air conditioning. Options included OnStar telematics system, cassette player, leather seating surfaces, front dual power bucket seats that could be heated, and side airbags for the front seats. A North Face Edition, in partnership with the North Face brand included limited exterior color options, a unique Ebony/Green leather interior, special exterior ornamentation and decals, white-faced gauges, OnStar telematics system, specially colored door panel inserts and speaker grilles, and more.
For 2003, the Avalanche was slightly changed. 2003 models featured a darker cladding, but GM's new president, Rick Wagoner, demanded the removal of this "unpopular" trim (as did certain elements of the public). From mid-year, Avalanche could be ordered without cladding. The uncladded model, known as "Without Body Hardware" (or its initialism "WBH," which is also an RPO code), and alternatively called "slicksides" by GM marketers, resembled the 2003–2005 Silverado 1500 in the front. A new interior—shared with the Tahoe and Suburban—added a new, larger steering wheel with subsequent audio, cruise, and speed controls; an optional six-speaker premium Bose sound system with external amplifier; a new gauge cluster with information center and memory for the front driver's seat, brake and accelerator pedals, and side-view mirror position (on some models); new radio head units, which included an AM/FM stereo with either a single-disc or six-disc CD/MP3 changer, Radio Data System, and optional XM Satellite Radio; standard OnStar telematics system with steering wheel controls; new warning chimes that played through the vehicle's audio system instead of through a separate speaker behind the dashboard; and newly available 17-inch alloy wheels and tires. Optional features included rear audio controls with headphone jacks and a rear DVD entertainment system by Panasonic with wireless headphones. The WBH option was only available in the 1500 series.

Common 2004 Chevrolet Avalanche 1500 problems
The 2004 Chevrolet Avalanche 1500 has been known to have several common problems based on complaints from owners of this car. Here are some of the most frequently reported issues:
- Fading Plastic Trim: The plastic trim on the sides, bumpers, and bed of the 2004 Chevrolet Avalanche 1500 can fade over time due to exposure to the sun and other elements. This can make the vehicle look worn and unattractive. To fix this issue, you can heat the plastic trim with a heat gun to warm it up and eliminate fading. However, this process can be time-consuming. For a faster solution, you can apply trim restoration to the plastic for about 5 minutes and then wipe it off with a microfiber towel.
- Check Engine Light for Fuel Trim Codes: The check engine light may come on for a fuel trim code like P0101, but it usually appears for a lean code like P0171 or P0174. This problem can be caused by an engine misfire or engine vibration. The engine needs an air/fuel mixture of 14.7:1 for the best engine performance and fuel mileage. The mass air flow (MAF) sensor and oxygen (O2) sensors measure this ratio. If air manages to get into the intake and pass the MAF sensor without a reading, it will throw the ratio off and trigger a check engine light. Parts that can cause a fuel trim code include a loose or broken air intake tube, broken intake gaskets, a faulty or dirty MAF sensor, or a faulty O2 sensor. To fix this issue, you may need to secure the air intake tube, replace it if it is broken, replace broken intake gaskets, clean a dirty MAF sensor, or replace a faulty MAF sensor or O2 sensor.
- Tailgate Handle: The tailgate handle on the 2004 Chevrolet Avalanche 1500 may not latch properly or the handle may break, making it difficult to open the tailgate. To fix this issue, you can take out the three bolts and two bolts that hold the cover, remove the cover, and take the handle off. Then, pop the rods off and put the new handle on. Finally, put everything back together and the tailgate should work properly.
- Excessive Oil Consumption: The 2004 Chevrolet Avalanche 1500 has been known to have issues with excessive oil consumption. This problem can be caused by worn piston rings, valve guide seals, or other engine components. To fix this issue, you may need to replace the worn parts or rebuild the engine.
- AC/Heater Issues: The 2004 Chevrolet Avalanche 1500 may have issues with the AC/heater system, such as the blower not working or the system not blowing cold or hot air. This problem can be caused by a faulty blower motor, a blown fuse, or a problem with the wiring. To fix this issue, you may need to replace the blower motor, replace a blown fuse, or repair the wiring.
These are some of the most common problems with the 2004 Chevrolet Avalanche 1500 based on complaints from owners of this car. It is important to note that not all vehicles of this model will experience these issues, and some may have different problems altogether. If you own a 2004 Chevrolet Avalanche 1500 and are experiencing any of these issues, it is recommended that you take your vehicle to a certified mechanic for diagnosis and repair.
