The Most Reliable Chevrolet Models: The Ones You Can Trust
Chevy has some genuine stars when it comes to dependability. Here’s what the data shows:
Chevrolet Equinox
The Equinox is a standout. It earned the top spot in the Compact SUV category in the 2026 J.D. Power Dependability Study . It also holds one of the highest average reliability ratings among Chevy SUVs, scoring 90/100 in J.D. Power quality and reliability ratings across recent model years . While the 2025 model year received a poor rating from Consumer Reports due to transmission issues, the Equinox’s long-term record is strong .
Chevrolet Tahoe and Suburban
These full-size SUVs are icons for a reason. The Tahoe topped the Large SUV category in the 2025 and 2026 J.D. Power studies . However, the 2021 model year of both the Tahoe and Suburban is one to avoid. Consumer Reports gave them poor reliability ratings due to major engine and transmission issues, which aligns with a high volume of owner complaints to the NHTSA . If you’re looking for one, newer model years (2024+) have better ratings .
Chevrolet Corvette
America’s sports car is also America’s most reliable performance car. The Corvette took first place in the Premium Sporty Car category in the 2025 J.D. Power study . Consumer Reports gave it an overall score of 91/100, with a 97/100 road test score and an 88/100 owner satisfaction rating . It’s not just fast; it’s dependable, too.
Chevrolet Silverado
The full-size pickup is a workhorse for a reason. The Silverado won first place in the Large Light Duty Pickup category in 2025 and took second place in 2026 behind the Ram 1500 . While it’s a dependable truck overall, there is a notable concern: some 2024 models have experienced transmission failures at very low mileage, with reports of the transmission going out at just 13,000 miles . Common transmission issues include hard shifting, slipping gears, and torque converter failure .
Chevy Models to Avoid: The Ones with Red Flags
Consumer Reports flagged six Chevy models to avoid, and the data backs up their warnings. These are models with documented reliability problems, often concentrated in specific model years .
2024 Chevrolet Blazer EV
A classic case of “avoid the first model year.” The 2024 Blazer EV has poor reliability scores, with reported issues involving the powertrain, high-voltage battery, build quality, and in-car electronics . It’s a new vehicle segment for Chevy, and the bugs are still being worked out. The 2025 model year may be better, but data is not yet available.
2021 Chevrolet Bolt
The 2021 Bolt is the worst-rated Bolt model year for reliability . It was plagued by a massive recall over battery fires, and owner complaints frequently target the electrical system and powertrain .
2025 Chevrolet Colorado
This midsize truck’s reliability took a nosedive in the 2025 model year. Consumer Reports gave it a “poor” rating due to problems with the drivetrain, 4WD system, differential, transfer case, and brakes .
2025 Chevrolet Equinox
While the Equinox is a top pick overall, the 2025 model year specifically is one to avoid if you’re considering a used one . Consumer Reports ranked it dead last in its class due to transmission issues (shifting problems, sensors, software) and in-car electronics problems .
2021 Chevrolet Suburban and Tahoe
The 2021 model year of these full-size SUVs is one to avoid . The redesign introduced major engine and transmission problems that are well-documented in Consumer Reports surveys and NHTSA complaints .
The 2026 Chevrolet Trax: A Value Play with Some Caveats
The 2026 Chevrolet Trax is a huge sales success, but it’s not without its issues. Owners have reported electrical system failures (e.g., the instrument cluster going black), engine problems (fuel injector failure, turbocharger issues), and air conditioning failures . The seats have also been criticized for being uncomfortable on long drives . If you’re considering one, it’s a great value, but be aware of these common complaints.
