Are Chevy Blazers a reliable vehicle?

In general, the Chevy Blazer is considered to have average reliability for its class. It tends to perform competently with routine maintenance, but reliability can vary by year, powertrain, and how well the vehicle is cared for. The introduction of the Blazer EV adds a new reliability landscape to consider, with battery and software factors playing a larger role.

Reliability for the Blazer depends on model year, trim, and drivetrain. Chevrolet launched the gasoline Blazer in 2019 as a stylish, mid-size SUV aimed at competing with class peers like the Ford Edge and Nissan Murano. Since then, owners and reviewers have noted a mix of solid ownership experiences and some issue clusters—particularly around early infotainment systems, occasional transmission quirks in certain years, and the usual warranty coverage questions. The Blazer EV, rolling out in 2024, introduces electric drivetrain reliability considerations such as battery longevity, charging infrastructure, and software updates. Consumers should weigh published reliability scores from sources such as Consumer Reports, J.D. Power, and NHTSA recall data alongside personal driving needs.

Gasoline Blazer reliability: what to know

The following points summarize factors that commonly influence reliability across the gasoline Blazer lineup, including engine choices and routine maintenance.

Powertrain and maintenance: The Blazer offers both a 2.0L turbo inline-4 and a 3.6L V6, both paired with a 9-speed automatic. Turbo engines can require careful maintenance and premium fuel, while the V6 is generally robust but can have higher maintenance costs over time.

Transmission behavior: Some early model-year Blazers experienced shifting quirks or rough shifts with the 9-speed automatic. GM issued software updates and refinements in later years to address feedback.

Infotainment and electronics: Owners have reported occasional touchscreen freezes, lag, or connectivity hiccups. Most issues are resolved with software updates or minor hardware fixes under warranty.

Recalls and service history: The Blazer has been subject to multiple recalls over the years. Verifying that recalls have been completed via the VIN check is a prudent step before purchase.

Ownership costs and resale value: Routine maintenance aligns with peer mid-size SUVs, with maintenance and repair costs generally in line with rivals; resale values vary by year and condition.

Bottom line: reliability on the gasoline Blazer is serviceable and often satisfactory, but it’s not uniformly excellent. Prospective buyers should research the exact model year, review service and recall history, and consider extended warranties if remaining in the vehicle beyond the basic coverage period.

Blazer EV reliability considerations

The Blazer EV represents Chevrolet’s entry into the growing electric-SUV segment. Electric-vehicle reliability hinges on battery health, charging compatibility, and software stability, in addition to traditional drivetrain concerns.

Battery and warranty: EVs typically come with robust battery warranties (often 8–10 years or a similar mileage cap) and predictable long-term degradation curves. Real-world range depends on temperature, driving style, and charging habits.

Charging and infrastructure: Reliability partly depends on charging availability and consistency of DC fast-charging networks, plus on-vehicle charging software and energy management systems.

Software and OTA updates: Electric vehicles rely heavily on software for performance, range optimization, and features. Over-the-air updates can fix issues after purchase but may require periodic attention from owners.

Electrical systems and cooling: EV components require proper thermal management; battery cooling and electrical subsystem reliability are active areas to monitor as the model ages.

Maintenance profile: Fewer moving parts than internal-combustion engines can mean lower routine maintenance, but repairs tend to be more expensive when they are needed, and service coverage for EV-specific components varies by market and warranty terms.

In short, the Blazer EV offers potential reliability advantages common to many modern EVs, such as reduced routine maintenance, but it also introduces new risk points around battery performance, charging behavior, and software reliability. Early ownership experiences and long-term data will better define its reliability trajectory.

What buyers should check before purchasing (gasoline or EV)

To gauge reliability before committing, use a structured approach that covers recalls, maintenance history, and model-year-specific issues.

Run a VIN-based recall and service-history check to confirm all campaigns are completed and service intervals are up to date.

Review the vehicle’s maintenance log: timing/drive belt (where applicable), transmission-fluid changes, coolant and brake-fluid services, and any non-scheduled repairs.

Consult reliability data for the exact model year from Consumer Reports, J.D. Power, and owner forums to identify any recurring defects or trouble spots.

Inspect the infotainment and electronics: test Apple CarPlay/Android Auto, Bluetooth connectivity, and touchscreen responsiveness.

Test-drive to listen for unusual noises, observe transmission smoothness, check HVAC performance, and assess ride quality under varying speeds and road conditions.

Following these steps helps buyers form a clearer view of expected reliability, while balancing other priorities such as safety, comfort, and price.

Summary

The Chevy Blazer sits in the middle of the pack for reliability among midsize SUVs. Gasoline models show solid performance with some year-to-year variability, especially around the transmission and infotainment systems, while the Blazer EV introduces new reliability considerations centered on battery life, charging, and software. For the best odds of long-term dependability, prospective buyers should research model-year reliability scores, verify complete recall repairs, and review maintenance histories, then weigh these factors against features, safety, and total ownership costs.

How long do Chevy Blazers last?

A well-maintained Chevy Blazer can last up to 200,000 miles or around 13 to 20 years, while the average lifespan is around 117,000 miles or 8.6 years. Longevity depends heavily on preventative maintenance, such as regularly changing the oil, checking fluids, and addressing potential issues like transmission or electrical problems. Some owners report their vehicles exceeding 200,000 miles with diligent care.

Factors influencing lifespan

Maintenance: Sticking to the recommended maintenance schedule is crucial for a longer lifespan. This includes regular oil changes, fluid top-offs, and other routine checks.
Preventative care: Address issues as they arise. Common problems can include electrical, transmission, or fuel pump issues, and catching them early can prevent major damage.
Driving habits: How you drive can impact your Blazer's lifespan. Responsible driving habits will help extend its life.
Driving conditions: Where and how you drive (e.g., city vs. highway) can also play a role.

How to maximize your Blazer's lifespan

Follow the recommended maintenance schedule in your owner's manual.
Check and top off fluids like coolant, brake fluid, and windshield washer fluid regularly.
Get professional detailing and washes every few months to keep the exterior and interior in good condition.
Change the oil and oil filter according to the manufacturer's recommendations.
Stay on top of any small issues that may come up to prevent them from becoming larger problems.
