GMC was rated poorly for the reliability of its vehicles in the annual Consumer Reports December 2024 reliability report, scoring just 33 points out of a possible 100 and rating worse than last year, when its reliability scored 36 points.
The average 2024 reliability for U.S. domestic automakers was 38 points, putting GMC solidly below average for dependability. European carmakers averaged 48 points, while Asian companies led the pack as usual with an average score of 57.
At the top of the list for reliability among Big Red’s models was the GMC Sierra 2500 HD, which scored 45, approximately equaling the typical model sold by a European brand. The GMC Sierra 1500 got a 39 rating from owner feedback, on a par with the U.S. auto industry as a whole.
At the bottom, the GMC Canyon was ranked at a remarkably low 15 out of 100 points for reliability. CR mentioned the mid-size truck model by name, stating that “engine, transmission, in-car electronics, and other problems” lie at the root of its low rating. Despite their rugged reputation, pickups overall were the poorest performing vehicle type in the study, with sedans first, minivans second, SUVs third and pickups dead last.
Notably, Subaru was the most reliable brand with a 68 rating. The reason for the Japanese carmaker’s success is a very specific strategy, according to Consumer Reports analyst Steven Elek: “Subaru’s cars share many reliable components.” He said this approach enables making new vehicles with fewer problems, since “[parts] commonality means that when Subaru redesigns a vehicle, it can make fewer incremental changes by carrying over dependable systems.”
Hybrids and ICE vehicles continued to be the most reliable types of vehicles by propulsion system. Plug-in electric hybrids had 70 percent more problems than ICE, with their dual power system increasing the number of things that can go wrong. EVs were in the middle between the two, with 42 percent more problems than ICE, but roughly half as many as PHEVs.
CRÂ ends its report by cautioning vehicle buyers who are concerned about reliability to not be early adopters, avoiding all-new, untried vehicles in favor of well-established lineages with the bugs worked out.

So, which GMC models fared well? Big pickups seem middling.
Consumer Distorts a totally paid advertisement for Toyota and Honda. This publication has constantly been a joke.
So sounds like I can expect problems with my 2021 1500 Sierra 5.3 AT4. So far 24K mi. all OK.
Hey at least GM full size trucks look sexy doing it
There all junk. Now. Not one good thing about chevys any more. Bad brakes engines. Transmissions what a shame there allowed to sell them there a vary dangerous. Vehicle.
GM full size trucks and SUVs are the best looking in the industry, if only they can get quality control nailed down. Hell I’m a Toyota guy but GM knows how to design a good looking vehicle
GM needs to learn that a good looking vehicle isn’t worth squat if it just falls apart. My 2019 Silverado is the last GM product I’ll ever buy because it looks great but fell apart at 52,000 miles. That’s not what I expect from a $65,000 truck.
