Recently freshened, the HD Sierras are designed for heavy towing and hauling, not ride comfort and handling. The 2500 and 3500 HD models are offered in two- and four-wheel drive as well as with the dual rear-wheel setup. Multiple bed sizes are offered. The standard engine is a 6.0-liter V8. We tested the 2007 2500 with 365-hp, 6.6-liter turbodiesel, which produced 660 foot-pounds of torque.

Owner Reports

Reliability History Reliability History The reliability charts are based on responses on hundreds of thousands of vehicles from our latest Annual Auto Survey. Consumer Reports subscribers reported on any serious problems they had with their vehicles during the past 12 months that they considered serious because of cost, failure, safety, or downtime, in any of the trouble spots included in the table below. The results are presented relative to the average model that year. Extra weight is given to the more serious areas such as major engine or transmission problems. Based on this data and further analysis, we predict reliability for the latest year. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

Owner Satisfaction Owner Satisfaction To learn about satisfaction, CR has collected survey data from our annual survey on more than half a million vehicles. Our subscribers provide great insights into their satisfaction by answering one simple question: If they had it to do all over again, would they definitely buy or lease the same model? In addition, respondents also rate their cars in six categories: driving experience, comfort, value, styling, audio, and climate systems. N/A indicates that we did not receive a large enough sample size to provide data for a specific year. An X indicates that the vehicle was not manufactured for a specific year.

The 2500 and 3500 HD models are offered in two- and four-wheel drive as well as with the dual rear-wheel setup. Multiple bed sizes are offered. The standard engine is a 6.0-liter V8. We tested the 2007 2500 with 365-hp, 6.6-liter turbodiesel, which produced 660 foot-pounds of torque. Our tested 2500 rode very stiffly but could haul a 2,200-pound payload. The diesel is punchy and not too noisy, and the Allison-made six-speed automatic is smooth. ESC is standard on some extended- and crew-cab models.

This is annoying giving a expensive vehicle a cheap feeling whenever the handle is grasped, the rest of the vehicle is to be admired. The door handle join lays right where your hand want to roll when opening or closing the doors. So far it has only been the front passenger and driver door afflicted."
