Overview & Reviews

The Chevrolet Avalanche is a distinctive utility vehicle that blends the comfort and passenger capacity of an SUV with the cargo capacity of a long-bed pickup truck. Its unique "midgate" feature allows it to be converted from a five- or six-passenger crew cab pickup with a short cargo box into a two- or three-passenger pickup with a long cargo box. A lockable hard plastic cover keeps the bed contents safe.

Produced for two generations, the Avalanche was based on Chevy's related full-size trucks and SUVs and therefore shared basic underpinnings and powertrains. Though it may command a price premium on the used-car market, the Avalanche also has more to offer than most pure trucks or SUVs. For the shopper in need of a jack-of-all-trades vehicle, either generation of this unusual truck should make for a smart choice.

Used Chevrolet Avalanche Models
The most recent Avalanche is the second-generation model produced from 2007-'13. Sleeker exterior styling, a sharper and more precise driving feel and increased interior refinement were its chief advantages compared to the first-generation model. It was offered in three trim levels: base Avalanche LS, midgrade Avalanche LT and plush Avalanche LTZ. Numerous luxury and technology features were available, including Bose audio, leather upholstery and a rear-seat entertainment system.

Rear-wheel drive by default, this Avalanche was also offered with two four-wheel-drive (4WD) systems -- one with a single-speed transfer case (introduced on the 2010 model) and one with low-range gearing (previously the only option). All models started with a 5.3-liter V8 that initially produced 320 horsepower and 340 pound-feet of torque (310 hp and 335 lb-ft with 4WD). A 6.0-liter V8 with 366 hp and 380 lb-ft of torque was optional from 2007-'09. (Note that rated power on these engines varied slightly through the years, but you shouldn't notice any real-world difference in performance.) Earlier Avalanche models had a four-speed automatic transmission, while a six-speed automatic (which helped improve fuel economy) became standard for 2009.

In reviews of the second-generation Chevrolet Avalanche, we consistently praised its exceptional versatility on account of the adjustable-length bed. From behind the wheel, we found the Avalanche to be comfortable and smooth-riding for such a workhorse, with robust acceleration from either of the proven V8 engines. The towing capacity impressed us at over 8,000 pounds, easily outdoing the car-based Honda Ridgeline, though trailing pure trucks with V8 power. Maneuvering in tight spots was a challenge, however, due to the Avalanche's massive size and considerable blind spots astern. Still, with its updated platform, it was markedly more pleasant to drive than the previous-generation model.

Aside from the powertrain changes noted above, this Avalanche received standard side airbags for 2008, and the LTZ was upgraded for 2009 with standard Bose audio, heated and ventilated front seats and leather upholstery. The final-year 2013 model was technically known as the Black Diamond Avalanche; it was treated to special badging and some additional features as standard.

The first-generation Chevrolet Avalanche was produced on an older platform from 2002-'06, making a name for itself with its innovative midgate, which was largely carried over to the second-generation model. This Avalanche is also very similar to the newer version in terms of passenger space. At its debut, the first-generation model was offered with two- or four-wheel drive and in 1500 (half-ton) or 2500 (3/4-ton) designations. The 1500 came with a 5.3-liter V8 good for 285 hp. The 2500 model had a 340-hp 8.1-liter V8 as well as higher towing and payload capacities. Both engines came standard with a four-speed automatic transmission.

In reviews of the original Chevrolet Avalanche, we gave it high marks for its trick adjustable bed and comfortable seating. Downsides included compromised outward visibility, low-grade interior materials and awkward exterior styling. The latter was partly attributable to the truck's standard-issue gray-color lower body cladding. Chevrolet wisely made it an option starting in 2003.

There were a few other notable changes during this Avalanche's run. The 2003 model year also saw the arrival of standard multistage airbags, optional stability control and a number of new features, while 2004 saw a slight drop in rated power for the 8.1-liter V8 (to 320 hp). Stability control was made standard across the board for 2006.

  Would get another one - 2002 Chevrolet Avalanche
  By Jim - February 17 - 7:53 am

  This is a great truck. Ive carried a Harley in the back and pulled a 10K travel trailer through the mountains (not the same time). The plus side of the setup is your friends dont look at it as a truck when they move even though it has all the ability. The only gripe is the 8.1L engines oil consumption is high. One qt in 3K miles when new, three qts in 3K now. Chevy claimed in 2002 one qt in 100 miles was considered high anything less is acceptable. Big engine is great for towing, stomp on the pedal and she jumps even at 70mph. Down side is MPG 11 around town 14 on the highway at 75mph. I would replace with same truck smaller V8 but right now Ill drive it until the wheels fall off.

  Fun gas guzzler - 2002 Chevrolet Avalanche
  By ivan - February 1 - 10:00 am

  Up to this point the Avalanche has been a unique fun experience. I traded in a Ford Expedition and dont regret it. The extra acceleration and smoother than expected ride of my new chevy is the highlight of my switch. I added 22 inch wheels and the truck really looks sharp and aggressive with a menacing look and stance. The Avalanche makes you feel secure and in control on the busy highways of the big congested city.

Comfort looks and room are the highs, power, gas and transmision are the low points. My last car was a BMW 4.6; The other ones I have now is 04 SL500, Audi Allroad.

  Its big! - 2004 Chevrolet Avalanche
  By phillipsjohnr - January 28 - 10:00 am

  Ive owned a Jeep Cherokee, Isuzu Trooper, and Toyota 4Runner and the Avalanche is by far the roomiest SUV Ive owned. Its also the most powerful. While the model I bought doesnt have all the amenities of past vehicles, it does have everything I want. It drives smoothly and quietly. The Bose stereo with XM it decent and Im still experimenting with the Midgate conversion options. The only downside - filling up with gas...

  Love my Avalanche - 2002 Chevrolet Avalanche
  By Frank C. - December 28 - 12:58 am

  I bought it new & now have 74,000 miles. I love this truck & would buy another. The major mechanicals engine, transmission, suspension, brakes, etc., no problems, however, the rear axle bearings had to be replaced at one point, which is the only problem that I have had with the truck. Very reliable & can always count on it. Very comfortable & smooth for a truck. Very useful, like the midgate & the rubber lined bed.

  Beware of Transmission Problems - 2005 Chevrolet Avalanche
  By KD - December 4 - 8:53 am

  Love the concept and versatility, but disappointed with reliability. I have had to replace the transmission at 32 months/49,000 miles (at considerable out-of-pocket expense) and continue to have problems with steering and front suspension noise.

  Perspective from a sporty car lover. - 2003 Chevrolet Avalanche
  By Kenjan - November 26 - 10:00 am

  First of all I must confess, I used to hate trucks and SUVs. After my purchase of the Avalanche, I must confess I really fell in love with it. A lot of people complain about the fuel economy and the exterior styling, but I love the styling and buying the truck knowing the fuel economy, so that should not be the consideration factor. The ride is excellent even with the z71, the usefulness is amazing with the convert-a-cab, and most importantly, it is such a fun vehicle to drive. I would recommend this truck to anyone without reservation.

  Chevy Avalanche - 2003 Chevrolet Avalanche
  By billyjcraw - November 1 - 10:00 am

  This truck (Z66,2x2 driving package) drives like a large car, smooth and quiet. The leather seating is comfortable, power is good. Turning radius leaves something to be desired. The styling is definitely for a particular taste. I like that Im getting a scaled down Cadillac Escalade (Same frame and body is used but with little style and cosmetic changes).Im interested in how reliable it will turn out to be. Ive picked up an annoying speed related noise coming from under the hood at about mile 3,000.
