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.

  Ava-Lemon - 2004 Chevrolet Avalanche
  By Ryan - August 4 - 3:58 pm

  I love the looks of the truck, but unfortunately it has started to fall apart. So far the front right axle seal had to be replaced, the battery started leaking battery acid all over the windshield washing resevoir causing it to leak the entirety of its fluid, theres a clunking noise in the front end, and theres also something wrong with the steering column. Itll be a miracle if I ever do business with GM ever again. The policies that their dealerships practice are not consumer friendly and at most have left me aggravated.

  Pros and Cons - 2004 Chevrolet Avalanche
  By k charland - August 2 - 2:00 am

  A few problems to look out for: The plastic side pannels rub on the front fenders causing rust spots. Just recently hit 30,000 mi. and now getting noise from the lifters and also squeeking from the belt. Oil was always changed on time. Very poor rear visability. Lots of noise and vibration with sun roof open. Poor quality stereo and speakers. Over all a nice truck with great features and pleanty of room for the passengers. Wish they would have put in a power rear window. Pain in the butt to have to lower rear seats and remove rear window. Many new trucks offer powered rear window.

  Avalanche Reveiw - 2002 Chevrolet Avalanche
  By Jakson - July 31 - 10:00 am

  This truck is a very nice truck i havent had any problems with it yet, and i dont think i will too soon. The only thing is the midgate makes shifting noises when you go over bumps, in the back you can hear it pretty good in the front you cant hear it as well other that that every thing works good, and it runs very nice.

  2 1/2 yr review - 2003 Chevrolet Avalanche
  By JC - July 25 - 6:43 pm

  Well I bought it because of the bed conversion capability. It seemed like a good idea, but in actuality more of a hassle to convert to full bed. The bed panels are a chore to remove and store. If you plan on using the full bed a lot, then get a regular pickup! No issues with the engine, but thats where it ends. In 2.5 years Ive been to the dealer for new rotors and pads all around at 5,000 miles, steering shaft replacement, Bose radio replacement, rear window replacement, faded cladding, center mount brake light replacment, regrease steering shaft, failed rear end, and failed transmission. All fortunately covered under warranty except the tranny. I baby the thing. Ive never towed or gone off road.

  Like it! - 2005 Chevrolet Avalanche
  By Dale - July 15 - 2:58 pm

  Bought the basic vehicle with only the Z66 package. it has all I need. I love the ride and versatility. I use the midgate at least twice a week for something. The look without the body molding but with the wheel flairs is great. I usually get tired of a vehicle within a year, but Ill be keeping this one for a number of years.

  Second one is the charm - 2005 Chevrolet Avalanche
  By Chuck Bachorski - July 14 - 12:59 am

  This is my second Avalanche. The 2002 model had many flaws. On my new vehicle, I ditched the cladding. This gives the truck a cleaner appearance and will prevent the cladding from coming loose. The ride on this vehicle is smoother, the braking is better and the fit/finish is tighter than the 2002 model. Fuel economy is approximately 16 mpg overall. I get 19+ MPG on the highway, which is pretty good for a vehicle of this size.
