2002 GMC Sierra 1500 Reviews, Ratings, Prices - Consumer Reports
If not for its disappointing reliability record, this competent pickup would be a Consumer Reports recommended model. The interior is quiet and roomy, handling and braking are good for a truck, and four-wheel ABS is standard. The four-door extended-cab versions are also the only such pickups with habitable rear seats. The front seats are large but not well shaped.

Owner Reports

Worse Better
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.

Model Summary
If not for its disappointing reliability record, this competent pickup would be a Consumer Reports recommended model. The interior is quiet and roomy, handling and braking are good for a truck, and four-wheel ABS is standard. The four-door extended-cab versions are also the only such pickups with habitable rear seats. The front seats are large but not well shaped. Four-wheel-drive models offer a selectable system with a full-time mode. The Sierra Denali is an expensive AWD model with a 6.0-liter V8 and a four-wheel-steering setup called Quadrasteer. This system enhances maneuverability in tight spaces and improves stability while towing.

In addition, since the vehicle was new there is a grinding noise when the steering is turned to the left at reduced speeds; first I was told it was too much lubricant in the steering cable and it was fixed... Not. Next, I was told it was the wrong lubricant in the steering cable, but that didn't fix it either. Then I was told the steering cable was routed the wrong way but they corrected it. Finally, I was told they had no more ideas and that it was probably just the nature of the beast. Seventeen years later it continues to grind... I am retired and on a fixed income and can't do anything about it. Professional Grade my butt!"
