The GMC Canyon and Chevrolet Colorado are practically twins. For the 2017, 2018 and 2019 model years, CR reported seeing recurring minor and major problems with the six-speed automatic transmission in both trucks. However, there was reliability improvement in this department for the 2020 model year.

More contributions to the pickups’ poor performance in the reliability-based index include issues with the paint/trim, body integrity, body hardware and in-car electronics categories. When CR gives a Reliability Score, data from road tests are considered, which didn’t play into these trucks’ favor.

The Chevy and GMC have previously been criticized for their choppy and stiff ride, uncomfortable standard cloth seats, awkward driving position and weak feeling. Engine problems further contributed to the poor reliability score.

5. Volvo XC90

The Volvo XC90 is a nicely appointed three-row SUV but suffers from problems that lower its reliability score. It has a bumpy ride and baffling controls. Audio, phone and navigation are controlled through a touch-screen infotainment system that’s difficult to use.

The most troubling parts of this vehicle are the drive system, suspension, brakes, body integrity and power equipment.

CR has tested every XC90 since the introduction of the second-generation model. Testing history allows us to see that major issues have been apparent since its introduction.
