2003 Chevrolet Trailblazer Review

Pros & Cons

  • Class-leading engine power, soft highway ride, room for seven in the EXT version.
  • Slow steering, generic interior design and materials, doesn't like to be pushed hard in the corners.

Edmunds' Expert Review

Finally, a midsize SUV from GM that can compete with the big boys.It could really use higher-quality interior pieces and a more tightly controlled suspension, however.

2003 Highlights

For 2003, a new trim package, named The North Face Edition, comes with items that Chevy hopes will attract people who like to venture off the beaten path. Starting with a TrailBlazer LTZ or TrailBlazer EXT with the Leather Plus Package, Chevy adds body-color cladding, unique seats, mesh map pockets, rain-sensing wipers, liftgate lighting, an underfloor storage cargo liner, heavy-duty cargo mats, an adjustable cargo shelf (EXT model only) and The North Face duffel bags and blanket. Not for you? Perhaps a V8 will suit your fancy. Chevy's 5.3-liter V8 is available on the TrailBlazer EXT only. Other changes for 2003 include a larger 22-gallon fuel tank (late fall availability) and additional child-seat anchors on EXT models. Chevy has also made some previously standard equipment optional, such as the side airbags, rear cargo shade, interior lighting and auto-dimming driver-side mirror.

2003 Trailblazer ls 4wd is one of the best ones.
LS 4WD 4dr SUV (4.2L 6cyl 4A)
2003 Trailblazer ls 4wd is one of the best ones Chevrolet built. Heavy duty. Easy Service. A DIY will find it a pleasure to maintain. The divers seat is not as comfortable as it could have been. That is the only thing I found at a slight fault. Lots of power very cold AC Fantastic radio. Summer City mpg between 13-13.5 with 3.42 axle. Highway mpg is 18.4 to 19. Winter city lowered to 11 to 11.5 in just city cold winter driving. Why? Not a clue.****Found low mileage issue. One rear inner brake pad was stuck on rear rotor all the time because floating caliper bracket pin was frozen due to rust. Thus half the pad was always pushing on rotor. Replaced "trashed worn out rotor" and caliper bracket and new pins added high temp caliper grease on new pins. Mileage went right up to 14 + mpg. The caliper bracket and rotor are VERY difficult to replace for a DIY. There was no problem with caliper. Still the same one. I should have known there was an issue like that because the left rear was pulsating every time you put the brakes on. Normal driving without foot on brake, there was no pulsating. Used new oem ceramic pads. Had that new SUV feel again.
Chevy Trailblazer in Summer or Snow is a Go Go Go
Dan the Fix It Man.,07/11/2018
LS 4WD 4dr SUV (4.2L 6cyl 4A)
Timely Brake pad replacement a must.New rotors at 100000. (A DIY issue for the rears but it can be done). Chaining Transmission Fluid and 4x4 Transaxle & front axle Fluid a must.(Change it early, say every 80000). Quality 5w30 syn oil ONLY for the 4.2. Change the oil & Filter every 3 to 4 months or around 3000 miles to give engine long life.(Don't leave the old dirty oil in for a long time, that causes wear.) Firestone Advantage 2 tires are the best tires for this suv at 33 psi. Keep your headlamps cleaned with non abrasive cleaner and put a dab of wax on them and polish. Put in cabin filters even though factory did not. It has a spot for them. The radiator fan clutch and while your at it belt should be changed at 150000. New battery every 3 years. Top off a/c charge every spring. The a/c on these runs COLD. "Perfect". Dexcool radiator fluid every 2 1/2 years. KEEP the undercarriage washed off, even in summer and especially in winter from road salt. Use a fuel cleaning additive every 3rd tankfull. Suggest the leading brand and it will keep the injectors clean. (Replace that air filter every 50000 with fuel filter at 75000 and Spark Plugs around 125000 with top ac brand. This is the best SUV gm ever built and it is on a Frame and not a uni body. The exhaust from catalytic converter back should last about 200000 if you keep it clean. (That is the only NON DIY Replacement parts job). The 4.2 mileage in city will stay around 13-14.5 and straight hwy only pops up to 19-20 mpg. Engine has enough power with the 3.42 axle. Sturdy as a hd truck and comfort as a full size sedan. Replace the back shocks at 175000 and make sure front and rear sway bar links are changed (total of 4) That is a tough job but someone has to do it.... No need for dealer service if your a DIY. Keep the factory wheels clean all year around. (by the way, lube spare tire crank area every year and test it.Buy weather floor mats in the winter. Use winter wiper blades front and the one on the rear The only issue after all these years is the drivers seat should have been more comfortable for extended HWY travel. (Some of the mileage timelines above may seem early but it will make the Trailblazer feel like factory new all the time, that choice is yours, do it early or follow GM time table. UPATE July 2020 : 17 years and it runs as good as new. Yes it does. With all the above done on a time table plus a new clutch fan at 200,000, & belts with pullys (WhY Not, it apart anyway.)Brand new battery every 4 1/2 years. A/C refrigerant added about every 2 1/2 years to top it off. YES, Trailblazers BLOW ICE COLD! Had to relace one of the Automatic Transmission Solenoids. Easy job plus new filter & fluid with a special non slip "RED" additive. Forgot the name. I also changed the rear axle fluild, getting the correct gasket from a parts sore was VERY difficult.Used Amsoil high gear oil. Used Rust-Oleum Wipe New Headlight Restore WIPES which restored my worn, foggy headlights lens. THIS WORKS and it does so quickly. Also I use every oil change 5w30 Full Synthetic with the Fram filter. USED crc mass air flow spray cleaner & the other CRC throttle body spray cleaner....SIMPLE to do. Only issue I had was trying to repair a couple of rear defog grid strips that I nicked. That to time to get the correct stuff that would work. I laugh at the new prices of any 4x4 SUV.I drive right past (what I call small SUV awd mini vans) in the snow. Ho Ho Ho.
Really nice car
EXT LT Rwd 4dr SUV (4.2L 6cyl 4A)
I fell in love with this car the moment I saw it. It has all the room our family needs, and plenty of safety features (such as front and side impact air bags and OnStar) to help us out if we need them. It has the DVD for the kids, and that could be considered to be a safety feature in itself! It has plenty of power for passing and getting on the highway, way more than you even need. The steering controls are also very nice. The standard stereo is enough for me, but it needs rear speakers for the kids. Love can sometimes be blind though. Fuel efficiency is not one of its best features, which is a growing concern.
Good value for the $$$
LTZ Rwd 4dr SUV (4.2L 6cyl 4A)
110 K mi. Absolutely no mech.issues to date. Good road ride, front seats are very comfortable , rear seats are not comfortable, tight entry/exit. Handles well on the highway, a little whale(ish) around town. The 4,2 L 275 hp engine is quiet and smooth with more than adequate power. Gas mileage is decent: 16-18 mpg city, 20-24 mpg hwy. With 55-60 mph cruise 25+ mpg. LTZ model but a basic Chevy w/bland, cheap plastic interior appointments. Excessive wind noise around windows. OA a decent American SUV for the money, not great, but a good value so far. I have not spent a penny beyond basic maintenance, which is a pleasant departure and surprise for a GM vehicle.

Should I lease or buy a 2003 Chevrolet Trailblazer?

Is it better to lease or buy a car? Ask most people and they'll probably tell you that car buying is the way to go. And from a financial perspective, it's true, provided you're willing to make higher monthly payments, pay off the loan in full and keep the car for a few years. Leasing, on the other hand, can be a less expensive option on a month-to-month basis. It's also good if you're someone who likes to drive a new car every three years or so.
