Overview & Reviews
The Avalanche gets numerous interior upgrades for '03 in addition to the midyear introduction of a "decladded" version that does without the oft-derided extensive lower body trim. Dual-zone climate control is now standard equipment on all models along with multistage airbags and a passenger airbag sensor. A redesigned instrument panel houses a more comprehensive driver information display; and an optional multifunction steering wheel puts climate, radio and trip computer controls right in the palm of your hands. New entertainment options include a Bose stereo system, XM Satellite Radio and a rear passenger DVD video system. Other new options include the StabiliTrak stability control system on 2WD half-ton models, adjustable pedals, and a fully automatic multizone climate control system.
- Versatile and innovative cab configuration, strong V8 engines, substantial towing ability.
- Some cheap interior pieces, lifeless steering, limited drivetrain choices.

Love the Avalanche but last 10,000 miles has been difficult! - 2003 Chevrolet Avalanche
By bill4516 - September 29 - 5:26 amIt is the best of both worlds. An SUV with the ability to haul stuff that you would not want in the back of your SUV. I ve hauled trees, plants, bags of fertilizer, and rocks.I own a 2003 Z66 with the cladding on the sides. At about the 100,000 mile mark the wheels just fell off. Not literally of course but it seemed that little stuff was going wrong all the time. My water pump went out, then my CD player, then my dash board lights, then the ever popular popping noise in the front end when you turn at slow speeds. Now I have a noise by my glovebox that sounds like someone dropping BBs on a tile floor over an over again. Still waiting on a fix for the popping noise. I still like it.

questionable head lights - 2003 Chevrolet Avalanche
By CLARENCE WHITE - February 15 - 9:50 amThe top parking light housing are like a piece of candy. the inside clamp that you snap the light in breaks super easy. Also the main driving light has a silver cap on the inside housing that falls off from the inside and eventually blows the inside bulb out. im writing this because something has to be done because this is my third top light housing that broke. This is my first main light housing that broke.

Down Hill - 2003 Chevrolet Avalanche
By jack - October 11 - 7:48 pmI bought my avalanche in june of 2003 at 2 years old the transmission went out and it doesnt jet out like it used to. Then it leaks water inside because it got hailed on and now its messed up so i think it might have shorted my electrical system because my airbag light came on. Then my passenger window recently went out so.

Most Functional Truck Made - 2003 Chevrolet Avalanche
By Biff - August 28 - 10:58 amI gave up my 2001 Toyota Tacoma d-cab for a used Z-71 with 50,000 miles over 3 years ago. For a family of 5, the usability of the back seats is second to none. Where the Toyota 3.4L V6 screamed to tow my boat, the Avalanche handles it like nothing. The flexibility of the mid-gate is terrific. The bed tonneau panels are easy to remove and have remained water tight. The truck has a smooth ride on the road but can still perform off-road. Now I have 87,000 miles and only problem has been the rear power door locks have frozen up and need to be opened manually.

Understand WMS limitations - 2003 Chevrolet Avalanche
By cag123 - February 2 - 10:00 amShould have read ALL reviews before buying. Water Management System does not meet my needs for dry cargo space. Tried to salvage vehicle investment with Snugtop/GM XUV cap. X = eXpensive, but would be worth it if it kept water out. It doesnt. Snugtop sales said "Of course its watertight"; now service says "weather resistant not waterproof"; no other response to dealer request for help. Have owned truck 33 days (25 with rain), 500 miles. Am trading it in tomorrow. Performance item: auto. transmission slow to downshift (book says to floor it!), but may be normal; have had manual transmissions for 35 years.

Would Be Great If It Worked! - 2003 Chevrolet Avalanche
By Lindsey - January 7 - 8:50 pmThis is absolutely an awsome vehicle, when it works. Bought it used with 75,000kms, had a few problems with it not starting in -15C the first winter but overall it ran good. Last year we started having issues, we bought it for $26,000 and weve put $18,000 back into it in maintenance ($8,000 in the last 6 months) . We cant get it running long enough to sell it. Had the entire front end torn apart a few times but no one can find the problem.

My Z66-No Problems/No issues - 2003 Chevrolet Avalanche
By David - October 29 - 4:47 amThis vehicle was/is a Godsend. We purchased it as a promotion present for me when I became a police lieutenant. Little did we know that we would end up living in it when I became disabled in 2004. We have towed a 28 ft travel trailer from New Mexico to Florida then to Oregon then back to Florida and finally settled down in Oregon. It currently has 128322 miles, most of those occurred by 2006,(2 years). It has not spent one day in the shop due to a breakdown or malfunction. A few things had to be addressed during maintenance (like minor recalls) but so far we have been and are thrilled with it.
