Vehicle Highlights

Redesigned for 2007, Chevrolet's reconfigurable pickup truck gained more power and features. Avalanche was essentially a crew-cab version of Chevrolet's big Suburban sport-utility vehicle, but with a folding midgate separating the cab from the cargo bed. Lowering the midgate extended the bed from 5.3 feet to 8.2 feet. With the Avalanche, Chevrolet competed against such conventional full-size pickups as the Dodge Ram 1500, Ford F-150, and Toyota Tundra. Ford's Explorer Sport Trac is set up on a similar principle, but smaller in size. Chevrolet's half-ton Avalanche 1500 model returned for 2007, but the three-quarter-ton 2500 was discontinued. Seating up to six, Avalanches came in LS, LT, and LTZ trim levels. A 320-horsepower, 5.3-liter V8 replaced the 2002-06 generation's 295-hp, 5.3 V8. A 310-horsepower version of the 5.3-liter V8 that could run on ethanol-blended fuel (E85) was a no-cost option for 2WD models, and standard on 4WD editions. Optional on LT and LTZ was a 366-horsepower, 6.0-liter V8. All engines had GM's Active Fuel Management cylinder deactivation. A four-speed automatic was the sole transmission. Avalanches were available with rear-wheel drive or four-wheel drive, which could be left engaged on dry pavement and included low-range gearing. Antilock braking and traction/antiskid control with rollover sensors were standard. GM's Autoride load-leveling suspension was standard on LTZs, optional for LTs. Avalanche LTs also were available with Chevrolet's Z71 Off-Road Suspension Package. Among newly available features were curtain side airbags that covered both seating rows, and included rollover deployment. Also newly available were rear obstacle detection and a rearview camera. Options included a navigation system and DVD backseat entertainment.

Consumer Guide® Road-Test Evaluation

Acceleration with the 5.3-liter V8 is good around town, but Avalanche has only adequate highway passing power. No difference is noticeable between 2WD and 4WD models. The transmission shifts smoothly and kicks down quickly. Cylinder deactivation is not noticeable while driving. Maximum towing capacity is 8200 pounds. Fuel economy could be worse, but isn't an attraction. Test 2WD Avalanche averaged 16.7 mpg in mostly highway driving. A 4WD model averaged 15.2 mpg with more city driving. All engines use regular-grade gasoline. The 5.3-liter V8 can run on E85 (an ethanol/gasoline blend). Surprisingly supple, the Avalanche rides impressively well for a large pickup. Only mild bounding occurs over large bumps, attributable to the basic truck design. Steering feels fine, though effort is rather high during low-speed maneuvers and while parking. Expect moderate body lean in turns. Brakes are responsive, with a short and firm pedal stroke. Because Avalanche is a long truck with a sizable turning radius, parking in tight spots is a challenge. Highway-speed wind rush and tire rumble are noticeable, but bump noises are well-suppressed. Engine whine intrudes only during rapid acceleration. Gauges are large and easy-to-read. Radio and climate controls are mounted low, but no trouble to reach. GM's optional navigation system absorbs but does not complicate audio functions. The wiper switch is inconveniently incorporated into the turn-signal stalk. Avalanche cabins are trimmed mostly with hard plastic, yet look upscale because many surfaces are textured. Front occupants get generous room on supportive, comfortable bucket seats--provided a bench isn't installed. Available power-adjustable pedals would be a boon to shorter drivers. Running boards aid exiting for shorter folks, though they tend to be a stretch-over hindrance to taller ones. Rear-corner views are blocked by huge roof pillars, while the tall tail restricts vision directly aft. Rear obstacle detection and the rearview camera are helpful, but the camera distorts distances, compromising its usefulness. Note that folding the rear seats to extend the cargo bed requires pushing front seats forward several inches, limiting legroom for taller occupants. Adults in the backseat enjoy plenty of headroom and adequate leg space. Three can fit across with some squeezing. The center position has limited foot space but a nearly flat floor. Foot clearance also is tight under the driver's seat. Comfortable enough, the rear seat has a fold-down center armrest with cupholders. Getting in and out is a stretch due to the high floor. Avalanche's versatile cargo bed has locking storage compartments outside, plus washable plastic walls and a rubber floormat. The hard tonneau and locking tailgate make it essentially a deep, 40-cubic-foot trunk. Removing the three-piece hard tonneau requires several leaps into the high floor bed-a job best left to the nimble. Lowering the midgate also is a several-step process. The bed hosts handy fold-out tie-down hooks. With the tailgate lowered, the optional rearview camera focuses on the trailer hitch, easing hook-up. Interior storage space is ample.

Each vehicle report contains one rating chart for representative model. Consumer Guide® rates in ten key areas: Performance, Fuel Economy, Ride Comfort, Steering and Handling, Interior Noise, Controls and Materials, Driver Room, Passenger Room, Cargo Capacity, and Insurance Costs. These ratings compare the particular vehicle rated to ALL other vehicles, not a vehicle's standing in a particular class. In the ratings table, "1" is the lowest rating and "10" is the highest rating.
Our reliability study for this generation Chevrolet Avalanche includes details on average repair costs, manufacturer recalls, and everything you need to know to gauge the long-term reliability of this generation Chevrolet Avalanche .

Trouble Spots

Consumer Guide's® Auto Editors have scoured repair bulletins and questioned mechanics to search for commonly occurring problems for a particular vehicle. In some cases we also give possible manufacturer-suggested solutions. In many instances these trouble spots are Technical Service Bulletins posted by the manufacturer, however, we have our own expert looking at additional vehicle problems.

Audio system: When using a portable music player (e.g. iPod) there may be noise in the car's speakers whenever the vehicle's power adapter is used and a ground loop isolator (from Radio Shack) is required between the device and the power outlet to prevent the noise. (2007-08)

Coolant leak: A drive belt pulley may rub a hole in the radiator vent hose resulting in a coolant leak and possible overheating. (2007)

Cupholders: The console cup holders allow drinks to fall out when cornering unless the original mats were replaced with liners having ears that retain the drink. (2007)

Electrical problem: Numerous electrical problems (door locks, power windows, speakers, courtesy lights etc.) may quit working because a wiring harness gets damaged by the seat belt. (2007)

None: The backup (rear vision) camera quits working due to an electrical connector coming loose. (2007)

Oil leak: An oil leak at the oil pressure sensor may cause the low oil light to come on and oil level to become low. (2006-07)

Wipers: The one-piece wiper blades may streak when driving at slow speeds because they do not press firmly enough and should be traditional, bridge style blades. (2007-08)

This chart details a range of prices in year-by-year listings for vehicles in three condition levels:
Good: a clean low-mileage, solid-running vehicle that needs little or no repair.
Average: a car with normal miles on the odometer, perhaps a few scrapes or dings; engine might need a minor repair or two, but runs acceptably well.
Poor: might have potentially dangerous problems with the engine and/or body, or abnormally high mileage; definitely in need of mechanical attention. Valuations reflect wholesale prices paid by dealers at auction, and retail prices on used-car lots. Each range covers all trim levels and engine types for a vehicle with a typical amount of equipment--usually an automatic transmission, air conditioning, stereo, etc. Fully loaded vehicles may cost more. Average mileage is 12,000 miles per year. Keep in mind that these are guidelines only. Actual selling prices vary- especially from region to region.

Detailed safety information for this generation Chevrolet Avalanche include detailed crash test scores from the NHTSA.

NHTSA Crash-Test Results

Test 2007 Avalanche
Front Impact, Driver 5
Front Impact, Passenger 5

The National Highway Traffic Safety Administration (NHTSA) tests a vehicle's worthiness in front- and side-impact collisions and rates its resistance to rollovers. Front-impact crash-test numbers indicate the chance of serious injury: 5 = 10% or less; 4 = 10-20%; 3 = 20-35%; 2 = 35-45%; 1 = More than 45%. Sideimpact crash-test numbers indicate: 5 = 5% or less; 4 = 6-10%; 3 = 11-20%; 2 = 21-25%; 1 = More than 26%. Rollover resistance numbers indicate the chance for rollover when the vehicle leaves the roadway: 5 = Less than 10%; 4 = 10-20%; 3 = 20-30%; 2 = 30-40%; 1 = More than 40%.

Learn about official auto recalls, reliability issues, and vehicle problems for the 2007-2008 Chevrolet Avalanche directly from the NHTSA and manufacturers.

NHTSA Recall History

2007 Avalanche: Certification/tire label may have incomplete tire/rim designation, and may be missing the tire-load rating.
2007-08 Avalanche equipped with a heated wiper washer fluid system: A short circuit on the printed circuit board for the washer fluid heater may overheat the control-circuit ground wire. This may cause other electrical features to malfunction, create an odor, or cause smoke, increasing the risk of a fire. Dealers will install a wire harness with an in-line fuse free of charge.
