Consumer Reports tests about 50 vehicles a year at its special auto test facility in Connecticut. However, not all cars will have a chance to stretch their stuff on the test track, and it is usually a GMC truck or SUV that will remain. So why does Consumer Reports decide not to take on a GMC?
Consumer Reports does not test models that are the same, such as Silverado and Sierra
According to Consumer Reports, there are many GMC models on the market, but some are pretty much the same as their Chevy counterparts. For example, the GMC Sierra 1500 is too similar to the Chevy Silverado pickup. Because of this, the two often get identical points or those that are very close to each other.
In this case, Consumer Reports tested the Sierra 1500 and gave it a total score of 47 out of 100. The Silverado 1500, which has always been pretty much a twin, received a total rating of 46. When you break both down to road test results, you get 78 for both. You also get a 1/5 predicted reliability rating and a 3/5 ownership satisfaction score.
When it comes to big SUVs, the Chevy Tahoe and GMC Yukon are very similar. Both have 73 road test results, and both happen to have a 1/5 predicted reliability rating and a 3/5 ownership satisfaction score.
Another set of vehicles that drive neck and neck as far as points from CR go is GMC Canyon and Chevy Colorado. Both are compact pickup trucks built on the same platform and both received a total rating of 45. Each model also received 61 on the road test, 2/5 in the reliability section and 1/5 points for the owner’s satisfaction.
Then there is the GMC Acadia, which is similar to the Chevy Traverse. In this case, however, the point is close, but you see some noticeable differences. Acadia has a test result of 80, while Traverse has a rating of 95. Overall, GMC’s medium-sized SUV received a rating of 70, and Chevyn received a rating of 83.
Some GMC models do not even get ratings from Consumer Reports
When two vehicles have minor style differences but are built in the same way and perform the same, one is often tested while the other never gets a grade. For example, GMC Terrain has no total points for the 2022 model. However, the Chevy Equinox, which offers many of the same features as the terrain, received a rating of 74 out of 100 points.
On the other hand, Consumer Reports gave the rating 3/5 for both predicted reliability and ownership satisfaction for the terrain. It is the same as what was given to the Equinox. When you look at the issues for both vehicles, the data seems identical.
Another set of twins, so to speak, are the GMC Savana and the Chevy Express, both of which are heavy commercial vans. However, none of these have been tested yet. Usually, in this case, the Chevy model will be the one to receive a grade when one of them rolls out for CR’s evaluation.
What about GMC’s powerful pickups?

Sometimes vehicles can not be rated because they are special editions of a truck or SUV that has already received points. The most common examples are the GMC Sierra 2500HD and its 3500HD model. These pickups are in a different class than the GMC Sierra due to the powerful shape. Still, both are still basic trim levels you can get with the Sierra model, only with heavier performing equipment.
The same goes for the Chevy Silverado 2500HD and 3500HD. None of these pickups were tested by Consumer Reports either. When it comes to predicted reliability and owner satisfaction, both the 2500HD models for GMC and Chevy received a rating of 4/5. 3500HD for both brands got 3/5 on reliability and 4/5 for owner satisfaction.
GMC and Chevy have models that almost mirror each other, so not all vehicles will be rated by Consumer Reports. They tend to favor the Chevy brand when choosing the ones they will evaluate. If you are interested in a GMC car and do not see any test results, check CR’s reviews of the nearest Chevy vehicle, and you will get a good idea of how well your potential car performed.
