Overview & Reviews

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.

  Shes a truck - 2003 Chevrolet Blazer
  By blazercanuck - March 7 - 5:05 pm

  I bought my 2003 Blazer zr2 at 120,000 kms (about 72,000 miles)about 1 1/2 years ago but I got a killer deal on it Only $4,500 but this price reflected the work it needed. Needed new tires rear brakes were seized new calipers, rotors and pads and needed an o2 sensor. In the past year and a half I have changed the lower ball joints both rear drive shaft u-joints front drive shaft (it has a C.V. style joint thats $500 new, picked a used one up for $100) and the idler arm (keep in mind i do a fair amount of off-roading/light rock crawling) This truck is TOUGH! nose dived HARD into a ditch and still drives straight as an arrow no damag Tailgate squeak? oil hinges. spare rattles? adjust latch

  Love my ZR2! - 2003 Chevrolet Blazer
  By dufmoney - October 25 - 10:24 pm

  I have put over 100,000 KMs on my 2003 Blazer ZR2 (current odometer reads 206,000 KMs) and the only thing other than maintenance I have ever had to do was the head gasket. This is is a fault on a lot of Chevy/GM vehicles from these years. She is so reliable though! Other than the tailgate squeak, which I am in the process of fixing, I have no complaints with this fast accelerating, smooth off-road driving, snow loving vehicle! If you want fuel economy, buy a Prius (lame). If you want a vehicle that is extremely reliable and comfortable, than buy a Blazer.

  I love my 2003 blazer - 2003 Chevrolet Blazer
  By mountainchick - August 20 - 7:00 pm

  Wow I was really shocked at some of the comments Ive 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 arent taking care of it but the owners beforehand didnt. 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 didnt 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 Chevys! The one and only thing I hate is changing the spark plugs because it is soooo tight in there!

  OK...But Could Be Better! - 2003 Chevrolet Blazer
  By dne_thompson - July 26 - 5:45 pm

  I bought my 2003 Chevy Blazer in June 2006, making me the 2nd owner. It had 32,000 miles and was just under warranty! By the time the warranty was up, about 2 months, the ball joints needed replaced as well as brakes and rotors. Had all work done under warranty! About every 15-20,000 miles, it has to have the ball joints replaced for some reason. I now have 86,000 miles on it and it is due for ball joints again. Also, my air conditioner quit working as well as my drivers side window. THESE ARE VERY EXPENSIVE REPAIRS! Also, have to do brakes and rotors about once a year. It is a good vehicle to drive though, especially with the sun-roof open and the cd player going. Great in snow!

  This SUV is OK - 2003 Chevrolet Blazer
  By kyle2004 - April 16 - 8:32 pm

  I purchased this car 8 months ago, and I am already looking to trade it in. It was a fun car at the beginning, but with 14 mpg and 16-18 on the highway, it is not worth it. Also, my 2003 looks exactly like every other Blazer model. Not complaining, but I would have liked some exterior updates to show some kind of evolution. I will hopefully be able to get some money out of it to trade it in.

  Getting Disgusted - 2003 Chevrolet Blazer
  By Christine - June 23 - 5:29 pm

  I bought my Blazer new. I liked the 4x4 look to it, and wanted another SUV. I have had to warranty replace the CD player. Also warranty work on stabilizer bar. My exhaust also kept running after I shut vehicle off. Dealer finally fixed. Water leakage in rear side windows, repaired once, just started leaking again now in"07. Water runs all across header and drips all over inside rear. Oil cooler lines also were leaking, water pump too, and ball joints. Luckily this was all repaired under warranty. The carpet wore through just after one year by the gas pedal. I have driven two Jeep Cherokee Sports before this purchase, never had any problems. Will probably not buy another Chevy SUV.

  Chevy Blazer LS 4x4 - 2003 Chevrolet Blazer
  By Phil G. - September 17 - 9:42 pm

  Ive got about 45,000 on this SUV with no problems. Its the most functional vehicle Ive ever owned. The interior is not trendy but very driver-friendly. The size is great, not as big as my wifes new Trailblazer, but big enough to seat 4 with ease with plenty of cargo room. The truck frame and engine, the Vortec, make it less refined but more durable than many of the newer SUVs. Its great in the snow, and theres enough muscle in the engine to handle passing on the interstate. Ive been thinking of trading it in on a newer SUV, but its hard to find anything I like better. I also like the styling, its big but not imposing.

  Not a bad SUV for a beginner - 2003 Chevrolet Blazer
  By Tim - August 28 - 12:37 pm

  Bought used with 32k miles. In stock configuration it is a dog. After installing new exhaust, cold air intake and using a Hypertech programmer, it runs much better. Quite a bit of body flex when offroad on moderate to easy 4x4 trails. Decent clearance. Limited modification potential due to offset of wheels. Very comfortable on and off road ride.

  I like it - 2003 Chevrolet Blazer
  By BlazerinMT - April 23 - 11:41 am

  Bought used with 16,000 miles on 2/04, I now have 62,150 in 4/06. A little over 45,000 miles in 2 years with no major problems! Replaced ball joints 1X, a fuel filters 2xs, thats it! Runs great, looks good and really great for getting the kids and all their stuff places.

  One Of The Best SUVs Ever Made. - 2003 Chevrolet Blazer
  By K to the L - December 30 - 4:05 pm

  This is the first Blazer I ever owned, however Ive been around numerous Blazers throughout my life, and they really are good solid SUVs. 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 dont 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
