Used 2003 Chevrolet Blazer SUV

2003 Chevrolet Blazer

2003 Highlights

The Blazer gets only a few minor changes for 2003. A new fuel-injection system helps smooth out the aging 4.3-liter V6 while the interior get refreshed with new seat fabrics. Two-door models are now available in a bright yellow exterior color while the Xtreme model gets new quarter-panel graphics.


  • Wide range of features and options, competent drivetrain, cheap price.


  • Spotty build quality, cheesy interior parts, uncomfortable rear seats, poor resale value.

Edmunds' Expert Review

If people keep buying them, Chevy will keep making them. We, however, suggest standing clear and going with the far superior TrailBlazer instead.

Bought it with 1Mile on it back in 2003
indiabradster, 8/12/2013
I take care of my cars. I can say this one has taken care of me. Comfy ride, in the 10 years that I've owned it, minus the normal wear and tear items I've replaced the fuel injection spider ($1000 repair). I needed to replace all the ball joints for inspection, which I did myself this weekend. Add up all the repairs at normal garage costs, $3000 in 10 years. That's great.
Last time with GM - 2003 Chevy Blazer
randyxgm, 12/7/2011
I have purchased GM vehicles for the past 20+ years. My last new purchase was a 2003 Blazer the vehicle has been a lemon from day 1. I have always taken care of my vehicles and done the recommended maintenance. Here's a list of some of the problems I've had with this car: Trans line leaks @3000 miles, car shuts off for no reason @ less than 20,000 miles, power windows work intermittently, small side rear window leaks during rain, making seatbelts wet, fuel gauge problems, wipers don't park, wheel bearings needing replacing @ 40,000miles, rear brakes seized up, U-joints needed replacing @ 70,000 miles, Rear differential seal blew-out @ 100,000 miles, Trans died @ 150,000 miles. GM sucks!
I love my 2003 blazer

Wow I was really shocked at some of the comments I've seen on here. First off I really believe that the way a truck works depends on how you drive it and maintain it! I am not saying that the people aren't taking care of it but the owners beforehand didn't. As for the worst gas milage I did agree untill I changed my fuel pump omg It saved me a lot of money and I didn't even change it because it was broke! If you drive like an idiot and go 55mph from stop sign to stop sign you will waste so much gas in anything. I go out the mountain every weekend and I have and always will buy Chevy's! The one and only thing I hate is changing the spark plugs because it is soooo tight in there!
One Of The Best SUV's Ever Made.
K to the L, 12/30/2005
This is the first Blazer I ever owned, however I've been around numerous Blazers throughout my life, and they really are good solid SUV's. I do agree that ever since the Trailblazer came along the Blazer is not respected the way it was back in the day, and it still should be. The engine and drivetrain are tough and were tuned for truck work. If you are looking for a reliable, dependable, solid, smooth running vehicle that has 4-wheel drive with a low price, the Blazer deserves a test drive. I probably would have purchased the Trailblazer since it is a bigger vehicle, however I don't care for the Vortec 4200 aluminum inline-6 as I feel that it will not hold up as good over time as the 4.3 does
