Furthermore, its competitive pricing on the used market provides good value, offering substantial capability for the money. Reliability was generally fair, especially with proper maintenance, satisfying both emotional needs for space and practical needs for utility.
The Bad
Known weaknesses for the 2006 Chevrolet Trailblazer EXT include potential issues with the fan clutch, inconsistent HVAC performance, and front suspension components requiring attention over time.

What Problems Does the 2006 Chevrolet Trailblazer EXT Have?
The 2006 Chevrolet Trailblazer EXT, like its shorter sibling, has several frequently reported problems and long-term reliability concerns that prospective buyers should be aware of. A common issue revolves around the fan clutch, which can fail, leading to overheating or a loud, roaring noise from the engine bay, requiring replacement. The HVAC system's blend door actuators are also prone to failure, causing inconsistent temperature control or airflow. Electrical problems are not uncommon; these can manifest as issues with the power window regulators, door lock actuators, or even dashboard instrument cluster malfunctions. The fuel level sensor in the gas tank is another known culprit, often providing inaccurate fuel readings.
Regarding the chassis, front suspension components such as ball joints, tie rods, and sway bar links tend to wear out, especially on vehicles with higher mileage, necessitating replacement for safe handling. Additionally, owners in regions with harsh winters have reported significant rust issues on the frame and underbody components over time. The 5.3L V8 engine, while powerful, can sometimes develop issues related to its Active Fuel Management (AFM) system, leading to excessive oil consumption or lifter problems. Recalls for the 2006 model year Trailblazer EXT have included issues such as potential short circuits in the headlamp switch that could lead to fires, as well as faulty ignition switches, which were part of a broader GM recall campaign affecting many models. It's crucial for any potential buyer to check if all applicable recalls have been addressed by a dealership.

How long will the 2006 Chevrolet Trailblazer EXT last?
The 2006 Chevrolet Trailblazer EXT, with proper maintenance, can achieve considerable mileage. Many owners report these vehicles reliably reaching well over 150,000 to 200,000 miles, and some even surpassing 250,000 miles with diligent care. Regular oil changes, transmission fluid services, and attention to cooling system components are vital for longevity. Long-term durability is generally good for the drivetrain, especially the 4.2L I6 engine, which is known for its robustness. However, weaknesses tend to emerge in the suspension components, electrical system, and the aforementioned fan clutch and HVAC actuators. Neglecting these common issues can significantly shorten its service life, but a well-maintained example offers many years of service.
What Technology & Safety Features are Included?
The 2006 Chevrolet Trailblazer EXT offered a utilitarian yet functional array of built-in tech and safety features for its era. Standard entertainment typically included an AM/FM stereo with a CD player, often featuring an auxiliary input jack on higher trims for external devices. Optional upgrades on LT models could include a premium Bose audio system for enhanced sound quality and a six-disc CD changer. For families, a popular optional feature was the rear-seat DVD entertainment system, which provided entertainment for passengers on longer journeys, often integrated into the ceiling.
Driver-assistance features were quite basic by modern standards, largely limited to essential systems. Standard safety features included anti-lock brakes (ABS) on all four wheels, which was a critical active safety component. Dual front airbags were standard, providing protection for the driver and front passenger. Traction control was often standard or optional on 2WD models and part of the 4WD system. Side-impact airbags were not standard and generally not widely available for this specific model year, which is a consideration for modern safety expectations.
Regarding crash-test ratings, the National Highway Traffic Safety Administration (NHTSA) provided ratings for the 2006 Trailblazer (which would apply to the EXT due to shared structure). It generally performed well, earning five out of five stars for frontal crash protection (driver and passenger) and five stars for side-impact protection for the rear passenger, and four stars for the driver. The Rollover Resistance Rating was typically three stars for 2WD and 4WD models, reflecting its higher center of gravity as an SUV. These ratings indicated a reasonable level of safety for its time.

2006 Chevrolet Trailblazer EXT Prices and Market Value
When new, the 2006 Chevrolet Trailblazer EXT carried an MSRP generally ranging from approximately $28,000 for a base LS 2WD model up to $36,000 or more for a fully optioned LT 4WD with the V8 engine. Today, its value has significantly depreciated, placing it firmly in the budget-friendly used SUV market. Current used market prices can range from as low as $2,500 to $6,000, depending heavily on mileage, condition, engine, and geographical location. Well-maintained, lower-mileage V8 LT models will command the higher end of this range. Factors affecting resale value include the overall condition of the interior and exterior, a clean title history, evidence of consistent maintenance, and the presence of desirable options like leather or the DVD system. Being an older, higher-mileage SUV, depreciation has largely run its course, making it a relatively stable purchase in terms of further value loss.
2006 Chevrolet Trailblazer EXT Cost of Ownership
Ownership costs for the 2006 Chevrolet Trailblazer EXT can be considered moderate to slightly high for an older vehicle. Insurance costs are typically reasonable due to its age and lower replacement value. Fuel costs can be a significant expense, especially with the 5.3L V8, as its EPA ratings are not high, making it less economical at the pump. The 4.2L I6 is better but still thirstier than modern crossovers. Maintenance and repair costs can be average if common issues are addressed proactively. Parts are generally affordable and widely available due to its GM platform sharing. However, recurring problems like the fan clutch or HVAC actuators, if neglected, can add up. Long-term, anticipate spending on suspension components and potential electrical fixes. Overall, it's not an exceptionally economical vehicle to own due to fuel consumption, but repair costs are often manageable if you find a well-maintained example.

How Does the 2006 Chevrolet Trailblazer EXT Compare to Other Sport Utility Vehicle?
The 2006 Chevrolet Trailblazer EXT faced stiff competition in the mid-size SUV segment, primarily from vehicles like the Ford Explorer, Dodge Durango, Toyota 4Runner, and Honda Pilot.
In terms of performance, the Trailblazer EXT's available 5.3L V8 offered a distinct power advantage over most rivals, especially when comparing base engines, making it a strong contender for towing. The 4.2L I6 was smooth but less powerful than some V6 competitors. The Ford Explorer and Dodge Durango also offered V8 options, providing similar robust performance. The Toyota 4Runner and Honda Pilot typically featured strong V6 engines, often with better fuel efficiency than the Trailblazer's V8.
Features were competitive; the Trailblazer EXT provided a spacious interior with standard third-row seating, a key differentiator. The Ford Explorer also offered a third row, as did the Honda Pilot, while the 4Runner was generally a 5-seater with an optional small third row. Interior quality in rivals like the 4Runner and Pilot was often perceived as superior, with better material choices.
Reliability is where the Trailblazer EXT could sometimes fall short compared to Japanese rivals. While the I6 engine was solid, other components like the fan clutch, HVAC system, and electrical issues were more common than in a Toyota 4Runner or Honda Pilot, which traditionally hold a stronger reputation for long-term dependability. The Ford Explorer and Dodge Durango generally had comparable reliability track records to the Trailblazer.
Price-wise, the Trailblazer EXT was competitively priced new and is now an even more affordable used option. Used Toyotas and Hondas from the same era typically command higher prices due to their strong reliability perception, making the Trailblazer a potentially better value for buyers on a tighter budget who are prepared for maintenance.
Alternatives: For outright reliability and strong resale, a Toyota 4Runner (V6) or Honda Pilot would be superior, though likely more expensive used. For similar power and towing capability with a third row, a Ford Explorer or Dodge Durango (with the Hemi V8) are comparable, but don't necessarily offer a significant reliability improvement.

Final Verdict: Is the 2006 Chevrolet Trailblazer EXT a Good Sport Utility Vehicle?
The 2006 Chevrolet Trailblazer EXT is ideal for families or individuals who need a highly functional, budget-friendly mid-size SUV with genuine third-row seating and decent towing capabilities. It's an excellent choice for those seeking maximum interior space for the money, especially on the used market. It is worth buying if you prioritize utility, a strong engine (particularly the V8 option), and a comfortable ride over cutting-edge technology or segment-leading fuel economy. Buyers should specifically look for well-maintained examples, preferably with service records, and be prepared for potential maintenance on known issues like the fan clutch or HVAC components. It's best purchased as a used vehicle, specifically an LT trim for enhanced features, understanding its maintenance history is paramount.
