GMC Ranks Low In Consumer Reports 2024 Reliability Report

Registering the lowest score for dependability among GM’s four brands, GMC ranked below average from multiple perspectives in the 2024 yearly reliability ratings published recently by Consumer Reports.

Several models ranked much higher than the GMC average according to the CR study, but others ranked among the least dependable vehicles of the study, including some of Big Red’s bestsellers.

The reliability rating operates on a scale of 1 to 100, with 100 being the most reliable possible. GMC came in at 36 points, putting it at 24th place out of 30 brands. It has twice the reliability rating of the 18 points scored by the last-place brand, Chrysler. U.S. automakers as a whole average 39 points, while European brands come in at 46 points and Asian carmakers offer the highest dependability with an average rating of 63.

Some Big Red models are strongly above average, including the GMC Terrain, whose 55 rating puts it on a par with Hyundai, Buick, and Infiniti. The GMC Sierra HD 2500 (51) and GMC Sierra HD 3500 (44) also achieved reliability notably above what is typical for American vehicles. However, the GMC Canyon got a 32 score, the GMC Yukon and Yukon XL both rated 30 points, and the popular GMC Sierra 1500 was least reliable at 29 points.

Overall, the study showed sedans to be most reliable among vehicle types. Cars rated at 57 points on average, which CR ascribes to their relative lack of cutting-edge – and thus buggy – technology. “Sedans have fallen out of favor with consumers,” observed Jake Fisher, senior CR director, “but as a class they are very reliable.”

SUVs, minivans, and pickup trucks were progressively less reliable, scoring reliability levels of 50, 45, and 41 respectively. Viewing the market with ICE vehicles as the benchmark, hybrids have 26 percent less problems than gasoline and diesel vehicles, while EVs have 79 percent more problems and PHEVs experience 146 more faults than their ICE counterparts.

To conduct the study, data on problems occurring in the past 12 months in over 330,000 vehicles was gathered from their owners. The model years involved include the 2020, 2021, 2022, and 2023 years, with a few 2024 model year vehicles also. Faults were assessed in 20 different categories of possible problems, with more serious issues affecting the reliability score more than minor annoyances.

  2. My 2017 Volt in Canada suddenly stopped on a highway and had to tow to a dealer. When the battery was all used and the engine came on, ithe display showed a message ” loss of propulsion”. Still ad the dealer since a month with no fix in site.

  3. I have subscribed to CR for years and they hate GM with a passion. They always use predicted reliability to lower GM scores.

    1. I’ve always thought there had to be money changing hands for CR to highly rate some of the junk they do like.

    2. Yeah and they have had egg on their face many, many times because they”predicted” a brand new Toyota model would be reliable and it turns out to be a dumpster fire. 2016+ Tacoma was one of those dumpster fires. The Camry had 8speed trans failures when the transmission was first rolled out. TC’s failed. Weird how those failures aren’t talked about. It’s like Toyota can rsell 2022 Tundras with engines blowing up left and right, and it gets ignored. But if a domestic brand has one issue, it’s all the evidence needed for the clowns to say they’re all junk compared to Toyota.

      CR is just a bad methodology. They base their reliability ratings on member surveys. Most of their members are west coast libs that have a natural bias in favor of JDM brands. It’s the wrong way to collect data on reliability.

  4. Thank God the thousands of people that buy GM products don’t RELY on CR.

  5. I love how you people just don’t want to admit that maybe GM makes a subpar product. It’s like you’re defending your grandmother instead of a mediocre car company. THIS DATA COMES DIRECTLY FROM THE OWNERS. I GUESS GM OWNERS ARE JUST MORE PARTICULAR THAN OTHERS OR MAYBE THEIR CARS JUST BREAK MORE OFTEN!

    1. Right on. My personal 40+ years of vehicle experience with all major brands and 40+ years of CR experience validates their real-world findings.
      Sad so many are quick to condemn CR without knowledge nor data.

    2. Actually it comes from people duped into buying a subscription to their B.S. rag. The huge majority of domestic brand vehicle owners don’t subscribe to their misinformation, skewed, propaganda machine. Surveys in general are a sampling of those who have a beef with their purchase. Looking for anyway to get back at the manufacturer. Happy customers are too busy enjoying their purchase and life in general.

  6. GM makes a horrible product that it doesn’t stand behind. I own a ‘18 Silverado. The transmission went on it with under 80k miles. It was 5 days outside of the warranty. Neither GM nor the dealership would do anything other than say you should’ve purchased the extended warranty.
    I want to buy American but why bother when they build turds

    Reply
    1. Your transmission has a powertrain warranty based on time or mileage not both . How could you vehicle have 80 thousand miles one day out of warranty. If you had an extended warranty you chose the duration . Also , people seem to think that maintenance is a thing of the old days vehicles . Unfortunately like your body you don’t treat it right it breaks down, just saying . I wouldn’t put much stock in CR as they are back door funded .

  9. My 2020 Acadia needed radiator at 30k miles. 3.5 years old and haven’t even bought tires yet. Dealer charged me $1,000

    Reply
    1. Why did it need a radiator? In 48 years of driving I have never replaced a radiator except for one damaged by a large chunk of concrete.

  10. One person survey. The Honda products I’ve owned have been generally much more trouble free than the GM products I’ve owned.

    Reply
    1. Every single GM car I’ve owned has been so unreliable that by the time I owned it a few years, I could have bought a Honda.

      The problem is that GM cars keep you so broke from the constant major breakdowns that you can never save up and buy a used Honda because THOSE hold their value, so you just get another cheap used GM problem car someone else doesn’t want anything to do with.

      Their 90s and 2000s stuff was already trash and the stuff they’ve made in the New GM era is worse.

      My Buick is in the shop every couple of months with something else that costs $1,000 at this point and I’m getting ready to just bite the bullet and wipe out most of my savings to buy a Certified Honda Civic.

      This will be the last time I drive a GM car ever. They’re usually already falling apart no matter when you buy them unless it’s brand spanking new and even then I hear bad things.

      I even had the engine blow up on one of them at 100,000 miles.

      This is just not acceptable.

      My Buick is now making a screaming noise on acceleration sometimes and I am so finished with this car.

  11. Well, after TWO major lifter/push rod repairs of the engine, each coating $5,800 in less than one year, I have to agree there are some serious reliability issues with my 2017 Sierra…and the exact same issue exists for all models 2014-2024. That’s why there is a class action suit against them. They deserve it.

    Reply
    1. It’s GM. There’s another class action lawsuit against them every year.

      My Buick got clogged up with that horrible orange engine coolant and I had to pay for a tear down to drill through the clog. And keep flushing and flushing it.

      They still use it. The person at Chevy admitted that the orange coolant STILL clogs heaters in 3 year old GM cars.

      So they just settle the lawsuit and then keep on using a thing they never plan to actually fix.

  12. I bought my last GM (Tahoe) new in 2013. At 72,000 miles my 5.3L had the camshaft, lifters, and several pushrods replaced due to GM’s Electronic Fuel Management System (8cyl to 4cyl pure-F-JUNK system)! I was told they are still using this f-junk system on the new ones yet. Never again! Over $5500 for the repair!

  13. I think the problem here is G.M. pays it’s bills by selling enough overpriced piles of junk to G.M loyal consumers. Is there anyone at General Motors who has the wisdom to come out and say it. Then begin to build better vehicles that the consumer wants. Honestly, why would anyone pay up to 80k for a 2.0 liter vehicle. And why pay the same 80K for a 2.7 liter vehicle. Vehicles are not interesting anymore. They have no personality that you can say is You. Press on the accelerator and you wait to see which gear it’s going to put itself in. Once vehicles went to electric steering, the essence of driving went missing. And is asking for a 13 inch screen, just to distract you from enjoying the scenery and not have this huge screen in your face. Oh,but can it be removed? No of course. Live with it too bad!! And that is what G.M. has accustomed itself to. It’s like a membership to a club that you have to pay through the nose with your own blood. If G.M. has forgotten, my used Buick would go to my son, then I would by another for me at an affordable price. G.M vehicles would go 300k back then so they are not any different now. Hell they won’t even reach 60K miles without a transmission replacement. So yes consumer reports does work on predicting which cars will have the least amount of problems in the future.

  14. Why are all of you GM haters on this site in the first place. I have been driving Chevrolet trucks/GM cars since 1973 and to this date, I have never, never had a bad Chevrolet/GM vehicle, most travelling over 150,000, 250,00, and even 301,000 trouble free miles. I’ve also had three Fords in that time period and that is why I am back to GM. [keep in mind, I gave them 3 chances]. Granted, to those who have had some problems, it is unfortunate; and those high repair bills are hard to handle. However, It can, and has, happened, to ALL manufacturers including Honda and Toyota. it’s not just isolated to GM. If you consider how many 5.3 engines are in circulation, obviously, some may/have encountered issues. I find it quite ironic, indeed, that if GM was so bad, why then, do they sell more full sized trucks than any other manufacturer, hands down. Do your research. The market is dictating large touch screens, multiple charging outlets, or run your household electrical systems with their F-150, or rate the quality of a vehicle by how many cup-holders it has or who has the largest touch screen. It seems that is what CR is only concerned with. Not all GM owners are dissatisfied with their vehicles; those that are, never let you forget it.

    1. That’s generally how I feel but this 2017 Sierra is kicking my butt. Two $6,000 repairs for a very well known problem with no support from GM is just too much for me. Fool me once…

    2. Most of us have been working up this hatred for GM as long as we’ve had them. Especially the ones that could only ever afford them used after the original owner can’t stand it anymore.

  15. The truth is Honda and Toyota owners will never admitt they have problems with there car.It would be difficult to admitt that you were wrong about the quality myth.Bottom line if you look after your car and don’t drive it into the ground it will last a long time. I have been driving gm products for 50 years and found them to be good vehicles .I think some people get on these forums and just spout off with very little knowledge of what they are talking about.Consumer magazine does not always get there facts correct and is certainly not a magazine i would rush out and buy to sway my car purchase
