Rating: 4.48
Based on 41 Owner Reviews ▶
Drew B | March 31, 2025
The 2003 Chevrolet Trailblazer marked a significant entry in the mid-size SUV market. Sporting a traditional body-on-frame construction, it offered truck-like capabilities with family-friendly features. Produced from 2002 to 2009, the 2003 model year offered trims like LS, LT, and LTZ. New, it ranged from around $28,000 to $35,000. It was popular for its powerful inline-6 engine, spacious interior, and available four-wheel drive, making it a versatile choice for many buyers.
The Good

The 2003 Trailblazer offered a strong blend of performance and practicality. Its inline-6 engine provided ample power for towing and everyday driving. The spacious interior offered comfort for families. While not the most fuel-efficient, it delivered good value for its price and capabilities. A practical choice for those needing utility, and emotionally satisfying with its rugged SUV styling.

The Bad

The 2003 Trailblazer had some known weaknesses. Issues with the four-wheel-drive system, particularly the encoder motor, were common. The instrument panel cluster often failed. Additionally, fuel economy was not a strong point. Rust, especially in northern climates, is also something to inspect carefully when considering a used model.

What Problems Does the 2003 Chevrolet Trailblazer Have?

The 2003 Chevrolet Trailblazer has several frequently reported problems. The instrument panel cluster is known to fail, leading to inaccurate readings. The four-wheel-drive system, particularly the encoder motor, often experiences issues causing it to malfunction. Other common problems include transmission issues, such as slipping or rough shifting, and electrical problems, like malfunctioning power windows or door locks.
Recalls for the 2003 Trailblazer included issues related to the fuel system and potential fire hazards. Long-term reliability concerns center around rust, particularly in areas with harsh winters, and the durability of the aforementioned electrical and mechanical components.
While specific issues may vary in severity, addressing these potential problems is crucial when considering a used 2003 Trailblazer. Pre-purchase inspections are recommended to assess the vehicle's current condition and identify any existing or potential problems. Careful maintenance is essential to prevent further deterioration and extend the vehicle's lifespan.

How long will the 2003 Chevrolet Trailblazer last?

Given its age, a 2003 Chevrolet Trailblazer could have accumulated anywhere from 150,000 to well over 250,000 miles, depending on usage and maintenance. With diligent maintenance, including regular oil changes and timely repairs, some owners have reported exceeding 300,000 miles. However, long-term durability is often impacted by rust, particularly in regions with road salt. Weaknesses over time typically involve the aforementioned electrical issues, suspension components wearing out, and potential drivetrain problems arising from lack of maintenance.

I bought my 03 Trailblazer used for $2,200 about 6 years ago. I have been in love with this truck ever since. Other than it being difficult to fuel, there is obviously a issue in the fuel inlet line (that I have never had checked but recently bought a 6ft. long inspection camera with LED lights on the tip to check into it) I haven't had to do anything buy but tires, a battery and change the oil in the first 5 years. I have had to put a significant amount of money into it in the last year, but only after my daughter took it off roading several times work her idiot friends that don't know a 4×4 from a passanger vehicle. So I did but front hubs, upper and lower ball joints on both sides, inner and outer tie rods on both sides, front lower control arm mounting brackets on both sides, both tail light assemblies, transmission safety interlock switch, brake light switch, cam shaft positioning sensor, Cam shaft actuator, alternator and starter. I have been chasing electrical issues and replaced the cigarette lighter and auxillary power port in the dash to resolve the OBDII port not having power. And am currently working on the brake lights not working. I know this sounds like a lot, and if you can't work on it yourself and have to pay a mechanic I'm sure it is. But all this was after 5 years of turn key driving. As well as after letting my 18 year old daughter drive it unchecked for over a month. And my wife drive it the first 5 years and absolutely refused to do any kind of maintenance on it to prevent future issues and catch the little ones before they became big ones. So if she had treated it properly and my daughter has kept the wheels on the pavement the vast majority of the work I have had to do would have never been a problem. All in all this is a strong engine in a very well designed 5 passanger midsized SUV that has 250,000 miles on it and the engine has not missed a beat. The standard issues with parts failing when they are not cared for or simply get old is about all the issues you can expect. And if you're doing it yourself working on this truck is easy. Just do yourself a favor and get a good heavy impact wrench, DeWalt has a good one with 700ft lb of torque. It will help with any suspension parts and taking off tires. Or you can get a 1/2" torque wrench and breaker bar and your set. My experience with this truck has been great. I wouldn't sell this truck for any amount of money even work the work I'm doing to it. It's a great vehicle that has been mistreated by people who don't know better and won't listen so they can learn. Remove them from the equation and this vehicle is an owner wet dream!

I have nothing else but good to say about her, she is a great vehicle. I am so glad I bought her. I believe I shall keep her till the end. I purchased this 03 trailblazer in 12/16. I bought her some new shoes(Goodyear Forteras). she has put over 39,000 miles on them. and I am getting her some new ones in about a month. I have put some new parts on her but she deserved them. as you can see I love this car. she has a little over 184,000 miles and she is still running strong.
Lovemytrailblazer
250,000 miles today 2/16/2019. I love my 2003 trailblazer. We Bought it in October 2002. Basic up keep. Replaced transmission once. I hope it lasts another 250,000
Negative Owner Reviews
LUV SUV's
Bought this 2003 model SUV with 28,000 miles on it. Have had too many issues to recommend it. The tail and headlights always go out. The top of the gas tank sending unit leaked gas all over the drive way and when you would drive it in 2008. Chevy first said no to the repair/replacement but then after I had it done sent the recall. Most recently the transmission that they say doesn?t need service until 100,000 miles needed service as in replacement ($2200) @ 100,000 miles. The all-wheel drive system has needed service, and this week the exhaust manifold replaced ($500). This truck is a rust bucket. The only good thing I would say is that it is comfortable and has good power and mileage for the 4.2 motor.

What Technology & Safety Features are Included?

The 2003 Chevrolet Trailblazer's built-in tech and entertainment features were relatively basic by today's standards. Standard features included an AM/FM radio with a CD player. Higher trims offered options like a Bose premium sound system and rear-seat entertainment. Driver-assistance features were limited; antilock brakes (ABS) were standard, and traction control was available.
Safety features included front airbags and side-impact airbags as optional extras. The 2003 Trailblazer received good crash-test ratings from the National Highway Traffic Safety Administration (NHTSA). However, it lacked modern advanced safety technologies like lane departure warning or automatic emergency braking, which were not common at the time.
Keep in mind that the technology found within this car is dated so don't expect modern features such as Bluetooth connectivity or Apple CarPlay. However, this does make it a simple vehicle with a basic design.

2003 Chevrolet Trailblazer Prices and Market Value

When new, the 2003 Chevrolet Trailblazer ranged from approximately $28,000 to $35,000, depending on the trim and options. Currently, used market prices can range from $2,000 to $8,000 or possibly higher depending on condition, mileage, and location. Depreciation has been significant due to the vehicle's age and the availability of newer, more efficient SUVs. Factors affecting resale value include mechanical condition, absence of rust, low mileage, and a clean title. Maintenance records can also improve resale value, as they are a form of proof of responsible ownership.

2003 Chevrolet Trailblazer Cost of Ownership

The 2003 Chevrolet Trailblazer isn't particularly economical to own. Insurance costs are moderate, but fuel economy is poor. Maintenance and repair costs can be significant due to the vehicle's age and potential for breakdowns. Parts availability is generally good, but labor costs can add up. Long-term ownership costs are influenced by the vehicle's condition and maintenance history; neglecting repairs will lead to higher expenses down the road. Rust repair can also significantly increase costs. Budgeting for unexpected repairs is a must.

2003 Chevrolet Trailblazer Insurance

Insurance for a 2003 Chevrolet Trailblazer is moderately priced, reflecting its status as a Sport Utility Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2003 Chevrolet Trailblazer Compare to Other Sport Utility Vehicle?

The 2003 Chevrolet Trailblazer competed against vehicles like the Ford Explorer, Jeep Grand Cherokee, and Toyota 4Runner. In terms of performance, the Trailblazer's inline-6 engine was competitive, but the Explorer offered a V8 option for more power. Feature-wise, the Trailblazer was comparable, though some rivals offered more advanced technology.
Reliability is where the Trailblazer falters compared to the Toyota 4Runner, known for its longevity. The Jeep Grand Cherokee offers more off-road prowess. At the time, the Trailblazer generally undercut the Toyota 4Runner in price, but used prices today are highly variable.
Alternatives to the 2003 Trailblazer include a well-maintained Toyota 4Runner for superior reliability, or a newer Ford Explorer for more modern features and potentially better fuel economy. A used Honda Pilot might also provide a more reliable and fuel-efficient option. The 4Runner will typically cost more.

Final Verdict: Is the 2003 Chevrolet Trailblazer a Good Sport Utility Vehicle?

The 2003 Chevrolet Trailblazer is best suited for budget-conscious buyers seeking a capable, older SUV for light-duty tasks. It's worth buying if you can find a well-maintained example with low mileage and a clean service history. A pre-purchase inspection by a trusted mechanic is crucial. Avoid models with excessive rust or signs of neglect. The LT trim offers a good balance of features and price. If reliability is a top priority, consider alternatives like the Toyota 4Runner, but be prepared to pay a premium. Don't expect modern comfort or safety features, and be prepared for higher maintenance costs.

Runs like a scalded ape on crack.

Easy to drive, easy to maintain. Entering an on ramp at 40mph, if you step the accelerator to the floor mine goes from 40 to 90 plus mph in 2 and a half seconds. 4.2 vortex v6. Scary fast. Mine is 4wd, currently won't engage will repair and pass truck to my daughter

Pleasantly surprised by its durability.

Bought this 2003 in July 2018 for $600. Did some basic maintenance (fuel pump, coils, brakes, u-joint) and have been driving it with no issues. In early June of this year, I took it on an 1,100 mile trip from NH to SC. No problems and the 4.2 averaged 19-21 MPG.

3RD CAR, BETTER THAN 1ST

This is my 3rd car over the last 5 yrs. I love my vehicles to be able to work on. My first was a '00 V6 Merc C280. It was my 2nd best car to the Trailblazer. The 2nd was a 99 SR20DE G20T with electric problems and was a gift. The Trailblazer was a gift to my Irish twin when we both turned 18. After my car became unuseable and i sold it i bought this off my brother to use as a work/daily. No other vehicle that i have ever owned has made to much torque to the wheel. I can step on it and go during the worst time of traffic and still bet the best MPG to my dollar. People keep telling me to get a real truck and all i have to say (most are Ford guys, but no hate) shush, you have a Ford, I have an LS...which one will break down first? I work on my own vehicles and have basically rebuilt my truck and still am. They however bring it to a dealer and don't listen. I know who will win this race. Lol.

Most reliable vehicle I have ever owned

250,000 miles today 2/16/2019. I love my 2003 trailblazer. We Bought it in October 2002. Basic up keep. Replaced transmission once. I hope it lasts another 250,000

Strong engine and great turning radius

Overall this has been a good car. The engine is strong and relaible. However there have been isues with the fan clutch, electric windows, and emmisions sensors. Over 15 years and 200,000 miles I have probably spent over $6000 on repairs other than normal maintenance and wear and tear. I like the way the car drives and the size- not to big and not too small. It tows well and has a good turning radius.

I've loved owning this vehicle!

This is the first SUV I've owned and I've really enjoyed having it. The Trailblazers have good functionality, nice visibility, smooth driving experience, multipurpose uses, are easy to repair/maintain, and did not give me any major issues. I acquired it as a "fixer upper" with lots of little things needing attention. With the care I gave it, I definitely got out of it what I put into it! This is a great vehicle for nearly any driver.
