The 2005 Chevrolet Trailblazer, a mid-size SUV, arrived as part of the second generation launched in 2002. It featured a traditional body-on-frame construction. Key trims included the base model, LS, LT, and LTZ. Its popularity stemmed from its truck-like capabilities combined with a relatively comfortable ride and spacious interior.

What Problems Does the 2005 Chevrolet Trailblazer Have?

Frequently reported problems for the 2005 Chevrolet Trailblazer often revolve around the transmission. The 4L60E transmission can experience hard or delayed shifting, leading to costly repairs. The HVAC system is another common area of concern, with blend door actuators prone to failure, resulting in inconsistent temperature control. Electrical issues, such as problems with the instrument cluster and power windows, have also been reported.
Rust is a significant long-term reliability concern, particularly on the frame and undercarriage, especially in regions that use road salt. Suspension components, such as ball joints and control arm bushings, can wear out prematurely, requiring replacement.
Recalls for the 2005 Trailblazer have included issues related to the fuel system and airbag deployment. Owners should check the NHTSA website for specific recall information related to their vehicle's VIN. Long-term, maintaining the cooling system and addressing any signs of corrosion are crucial to prevent major mechanical failures. Regular fluid changes for the transmission and differentials are also recommended to extend the vehicle's lifespan.

How long will the 2005 Chevrolet Trailblazer last?

With consistent maintenance, a 2005 Chevrolet Trailblazer can realistically reach 200,000 miles or more. Many owners report vehicles lasting 15-20 years with proper care. However, long-term durability is heavily dependent on maintenance habits. Neglecting issues like rust, failing to address cooling system problems, or skipping transmission fluid changes can significantly shorten its lifespan.
Weaknesses over time include rust, suspension wear, and potential for engine issues (especially with the V8 if not properly maintained). Regular inspections and preventative maintenance are key to maximizing its lifespan.

Very comfortable, smooth ride plenty of room rides 6 in complete comfort, the L6 4.2 provides plenty of power still looks sharp for 2005 model and the most dependable vehicle I've ever owned. I bought it used and it feels like new. the only problem I've had is the rear ac system other than that it has exceeded my expectations,200,000 miles, and runs better than the day I bought it used with 125,000 miles, like any piece of equipment you have to take care of it. Preventive maintenance and quality products used on it, treat it like a family member This vehicle is worth the time and money no doubts.
Aunt Lizzie
This vehicle is the best Chevy ever made in my opinion. Mine currently has 225 thousand mines. Have replaced tires, battery and ac compressor only in 16 years.

nothing was wrong with my 2005 Chevy trailblazer ext other than than when i got into a severe accident the air bags did not go off. i first launched 90 feet off of a ditch culvert and landed on the roof and preceded to roll every witch direction for an additional 60 foot before coming to a stop and no safety features worked other then the seat belt held me in. i contacted general motors and they said there was no problems with the air bag system but there just want enough front impact damage... im lucky to be alive so be smarter then i was and DO NOT buy a trailblazer... I will never buy another general motors vehicle after them not doing anything about this issue
Mother of Two
I bought a used 2005 Trailblazer in Feb 07, immediately it needed to have the head replace at 57,000 miles which was under the 60day warantee. Several months ago we had to replace the dash cluster and then two weeks ago the motor let go, and the transmission is leaking. For a used motor it is costing $4300 to replace it and the new motor is at 35,000 miles. I worry about having the same head problem in a couple years. The maintenace on this vechile is unbelievable. We bought it to tow our pop up and are unsure at this point if we will be able to use it for that reason.

What Technology & Safety Features are Included?

The 2005 Chevrolet Trailblazer offered a fairly basic level of tech and safety features for its time. Built-in tech included an AM/FM radio with a CD player, with higher trims offering features like a Bose premium sound system and a rear-seat entertainment system (optional). Navigation was not commonly available as a factory option.
Driver-assistance features were limited, primarily consisting of features like cruise control and available four-wheel drive. Safety features included standard front airbags, anti-lock brakes (ABS), and available side-impact airbags on some trims. Traction control was also available.
The NHTSA (National Highway Traffic Safety Administration) crash-test ratings for the 2005 Trailblazer are as follows (results can vary slightly depending on the specific configuration):
  • Overall Frontal Crash Safety: 4 out of 5 stars
  • Overall Side Crash Safety: 5 out of 5 stars (with side airbags)
  • Rollover Rating: 3 out of 5 stars
Keep in mind these ratings are from 2005 and may not be directly comparable to modern vehicles with significantly advanced safety technology. While it offered adequate safety for its time, newer vehicles generally provide a higher level of protection.

2005 Chevrolet Trailblazer Prices and Market Value

When new, the 2005 Chevrolet Trailblazer ranged from approximately $27,000 to $35,000 depending on the trim level and options. Currently, used market prices typically range from $4,000 to $8,000, although exceptionally well-maintained examples may command slightly higher prices.
The Trailblazer has depreciated significantly over time, as expected for a vehicle of its age.

Rust-free examples in good mechanical condition generally hold their value better.

2005 Chevrolet Trailblazer Cost of Ownership

The 2005 Chevrolet Trailblazer is not particularly economical to own. Fuel costs can be higher than modern SUVs due to its older engine technology. Insurance costs are generally moderate. However, maintenance and repair costs can be significant, especially as the vehicle ages. Common issues like transmission problems and HVAC failures can lead to expensive repairs. Long-term, expect to spend a considerable amount on upkeep to keep it running reliably. It is considered a moderately costly vehicle to own.

2005 Chevrolet Trailblazer Insurance

Insurance for a 2005 Chevrolet Trailblazer is moderately priced, reflecting its status as a Sport Utility Vehicle with strong safety ratings and
reasonable repair costs.

How Does the 2005 Chevrolet Trailblazer Compare to Other Sport Utility Vehicle?

The 2005 Chevrolet Trailblazer competed against vehicles like the Ford Explorer, Jeep Grand Cherokee, Toyota 4Runner, and Nissan Pathfinder. In terms of performance, the Trailblazer's inline-6 engine was competitive, but the V8 offered more power than some rivals. Feature-wise, it was comparable to the Explorer but lagged behind the Grand Cherokee in terms of luxury options.
Reliability is where the Trailblazer fell short compared to the Toyota 4Runner, which is known for its exceptional dependability. The Nissan Pathfinder offered similar reliability but with a slightly less truck-like feel. Price-wise, the Trailblazer was generally competitive.
If reliability is a top priority, the Toyota 4Runner is a significantly better alternative, albeit potentially at a higher price point. The Nissan Pathfinder offers a similar blend of features and reliability at a comparable price. The Ford Explorer offers more modern features, but reliability can be a concern. Ultimately, the best alternative depends on individual needs and priorities. For someone wanting a powerful engine and capable SUV on a budget, the Trailblazer might be suitable, but buyers should be aware of potential reliability issues.

Final Verdict: Is the 2005 Chevrolet Trailblazer a Good Sport Utility Vehicle?

The 2005 Chevrolet Trailblazer is ideal for someone seeking a capable and relatively affordable SUV with a truck-like feel. It's best suited for those comfortable with performing some maintenance themselves or willing to budget for potential repairs. Whether it's worth buying depends heavily on its condition and price.
A well-maintained, rust-free example with a thorough service history can be a decent value. However, be wary of neglected examples, as repairs can quickly exceed the vehicle's worth. Opting for a lower trim level (LS or LT) might be a better choice than a higher-mileage LTZ, as fewer features mean fewer potential problems. It's generally not recommended to buy this vehicle new, as that's impossible. A thorough pre-purchase inspection by a trusted mechanic is crucial.

It's a chevy!

They should have never even made a 6 cly model.. A bicycle in the wrong gear has more power. I live in the mountains it's not very great in the snow. Actually it can't corner fur shyt. Unless you like leaky tires. Chevrolet has too many arrows and little writing, on everything on the dash. Again it was a gift and I'm not a chevy person. Other than that Chevys are dependable I Just don't like They're designes interior

Quietst & most reliable car ever owned

This car was bought in 2005 as a repo with only 5,000 miles. This car has been very reliable it has had some minor common issues all the speakers stopped working due to cheap factory speakers, the speedometer stopped working but got a discount beacuse there was a recall on the speedometer, the ac had to be reharged. That is it this car has been great for road trips and family outings it has proven to be very spill restint a shake got spilled and a bottle of grape juice exploded and didn't leave a stain. This car is very well balanced too I climbed a 40 degree gravel hill with 4wd on and it went right up the hill. Now it has 170,000 miles and needs a tune up and fluids replaced.

Most reliable car I've owned

I've own my 2005 Trailblazer since 2006 when it had 1300 miles on it. My Trailblazer has almost 300,000 miles on it now. I have had to replace many parts but, it still runs great. I love the interior, exterior design which makes it easy for me, 4'10", to access rear. Also has plenty of room. I won't own another vehicle, I'll just keep replacing parts as needed. It had the best engine made with the inline 6. I used it to travel 200 miles to work and back, towing camper, moving, hauling family, 4 wheeling, and leisure for my retirement now.
