2024 Chevy Silverado TurboMax Engine Gets Longer Warranty

As previously covered by GM Authority, the turbocharged 2.7L I4 L3B gasoline engine was recently assigned the TurboMax nomenclature in an effort to highlight the boosted four-banger. Now, General Motors has extended the TurboMax’s warranty for the 2024 Chevy Silverado 1500.

Intended to display GM’s confidence behind the engineering and design 2.7L L3B engine, the Detroit-based automaker has announced that it is extending the TurboMax’s powertrain warranty from five years/60,000 miles to five years/100,000 miles.

It’s worth noting that this update makes the TurboMax’s warranty 40,000 miles longer than those of its competitors.

“As we’ve said before, we engineered TurboMax to deliver the durability and performance expected by our truck customers,” Assistant Chief Engineer Kevin Luchansky was quoted as saying. “The result continues to turn skeptics into believers with best-in-class 430 pound-feet of torque and 310 horsepower. The whole team is proud of this engine, and this warranty extension exudes our confidence.”

Of course, the 2.7L L3B is offered as the starting powerplant option for the 2024 Chevy Silverado 1500. Available on WT (Work Truck), Custom, Custom Trail Boss, LT, RST and LT Trail Boss trim levels, the TurboMax covers a wide berth of owners’ needs. Only offered in the High Output tune, the boosted four-pot develops a maximum output of 310 horsepower and 430 pound-feet of torque, along with an available maximum tow rating of 9,500 pounds.

Other engine options for the 2024 Silverado 1500 include the naturally aspirated 5.3L V8 L84 gasoline engine, rated at 355 horsepower and 383 pound-feet of torque, the naturally aspirated 6.2L V8 L87 gasoline engine, rated at 420 horsepower and 460 pound-feet of torque, and the 3.0L I6 LZ0 turbodiesel Duramax, rated at 305 horsepower and 495 pound-feet of torque.

  1. What’s that smell? Ohhhh… DESPERATION. OF COURSE CUSTOMERS ARE SKEPTICAL.

    1. Was waiting for a 2024 because it will have the 2nd gen 8AT, which I expect they resolved all the issues of the 1st gen. Warranty extension is welcomed news. Will finally replace my soon to be 20 year old Colorado (2004).

  2. I don’t know if this is desperation or to cycle up sales for this engine and off the V8s so they can transition the next gen V8 manufacturing and the production lines.

    This engine sells pretty well on the volume truck models, desperation doesn’t explain the incentives and this new warranty

    If you figure all the trucks and SUVs that have V8s it’s a TON of units they don’t want interrupted when the new V8 comes into the fold

    1. Any idea when the new 5.3L updated engine is expected to launch?

      Reply
      1. It’s supposed to be an ‘all new’ V8. I wouldn’t be surprised if the 5.3 and 6.2 displacement don’t make a return and instead a single mid-bore V8 offering. Maybe a DOHC? I’m surprised we haven’t heard more rumors about it

        Reply
    2. I suspect CAFE plays a role as well. The 2.7L might not deliver exception fuel economy but the emissions are lower.

      Reply
    3. Please just for a minute forget that this engine is a gas engine, and think of it as a diesel engine. You wouldn’t think of it as unable to handle stress of high cylinder pressures, because diesel engines are designed to handle high pressure. Don’t you think that the engineers thought of this too? These are very well designed engines that are built to withstand high temperatures and high pressures. Only idiots would keep building engines and transmissions that would not withstand heavy use. I’ve driven both Fords and Chevys with the 2.7 engines and they were both great. The Fords pull better at higher rpm’s. Chevys are smoother and quieter but thirsty! The GM diesel in the half ton is butter smooth and thrifty, but that’s a story for another time.

      Reply
      1. Yeah, but you don’t rev a diesel engine to 5600 rpm to get the power out of it, and they generally don’t have cylinder deactivation on them.

        Reply
        1. You don’t have to “rev” the 2.7 turbo to 5,600 rpm either, max torque hits around 1,600 rpm and holds there until after 4,000 rpm.

    4. Doesn’t make sense. The same motor 2.7 turbo in the 2023 Colorado and the warranty is staying at 5 and 60,000 miles . INTERESTING

  3. I have sold around 10 of the 2.7’s over the last couple of years. We haven’t ordered that many. It’s not a volume engine in my store. It’s basically been in entry level trucks for us. Personally, I haven’t had a customer yet with regrets. They love it. I get it, it’s not for everyone but it seems to be a well engineered engine.

        1. It’s 5yr/100k, the same as the Turbo Diesel warranty.

  5. I am having trouble believing that something small, stressed and under pressure will be able to perform to the established standards of something large, understressed, and naturally aspirated when it comes to longevity, and even fuel economy. The 5.3 is such a hard act to follow. Customers by and large have not been enthused about the 2.7, that much is clear with the relentless pushing from gm to try and sell it in the larger trucks.

    When it first came out I thought it would be ideal for the mid-size twins, but after seeing all the independent tests/videos, I am content to keep my 2019 Colorado with the 3.6. I mean, the power and economy are great without the added complication of a turbocharger.

    3. Well, they sell almost 100k of them each year, so…

      Reply
  6. GM has has far less luck with reliability on small displacement turbo engines compared to the naturally aspirated larger engines that preceded them. Ford too. And for what? Generally the same or worse fuel economy? On a large truck, I’d run away even faster. Warranty should have been more than 5 years.

    Reply
  7. Well let’s see, rebates didn’t work so let’s extend the warranty and maybe we can sell them.

    Reply
    1. Exactly.

      They’ve clearly done their marketing research with truck buyers and like many posters on here, buyers told them they have serious reservations about the long term longevity of a turbo 4 in a full-size truck. The classic marketing answer is to slap a longer warranty on a product to try and alleviate buyer concerns. Rebranding is another answer.

      I have no idea about this engine’s longevity in this application but I do know (from my truck product planning days) that full-size truck buyers keep their vehicles close to eight years (from new). The duty cycle can run from mild (passenger car type usage) to extreme (over spec work in harsh environments ) and that scrappage rates don’t ramp up until the 14-15 year mark (long product lifecycle). That means second and third owner experience is also important so it’s important to talk with them as well.

      As you would expect, durability and dependability are BY FAR the top purchase reasons in the segment. During my truck planning days I liked to tell the development teams to “plan for the worst, then double it”.

  8. if it does not have cylinder deactivation the 5.3 has that would be a plus on the durability side.

  11. Question for anyone who knows:
    Why was the 4.3 V6 done away with for this? It was simple and already proven. I’m not against the 2.7, excited to drive one actually, but i don’t understand the move. Why not just keep the 4.3 and make it a powerhouse or more efficient or whatever direction they wanted to take it?

    1. The 4.3 was a great engine. Basically a 5.7 minus 2 cylinders

    3. Humm, wonder if they will extend this warranty to the Colorado/Canyon twins? It’s the only engine you can get.
      Another public relations mess if they don’t….

  12. Tell us you don’t know what you’re talking about without actually telling us. Do you have any idea how this stuff actually works or are you just offended GM built one heck of a four cylinder and it hurts your ego the V8 is dying. Stop using a truck as an image purchase and you’ll see why it’s a good motor for those that work their trucks…

    Reply
    1. This only proves that people are conditioned to believe one way (only V8 engines can do big work in a half ton pickup). This mindset is what GM is really fighting against right now, not that the new engine might not have what it takes. People don’t like change, and unfortunately this is a big change for the truck buying community.
      The next big thing is really going to upset some folks and that’s, EV trucks! Come and get you some of that? Enjoy it while you can folks, it’s coming.

  14. It’s a good engine for people who don’t use their trucks as trucks. And there are a lot of those folks. Leaders, light use fleets, etc. I am just not one of them.

  15. The 2.7L might be the best engine GM ever built (I’ve no idea), but it doesn’t matter because you’ve got so many old guys that think they have to have a V8 or at least a V6.
    It’s going to take a decade or more before everyone is comfortable with a 4 cylinder turbo in their truck, partly because so many of those old guys will be dead.

    Reply
    1. With reliability and durability being THE top purchase reasons in the segment buyers of all types tend to want a proven commodity for their fifty large. When and if the turbo 4 proves itself it’ll do just fine.

      By then, even newbies who know nothing about the truck segment may grow up and buy one.

  16. Will the 2024 Colorado and Canyon have the same warranty 5 years/ 100,000 miles ? Since dealers can start ordering them the week of August 24th2023. With scheduled production date of October 30th 2023. Silverado 2024 production date set to start on July 17th 2023.

      1. So your saying it’s not getting advertised fuel economy or you don’t like it’s fuel economy…there’s a difference.

        1. I recently bought a Silverado with the 2.7 engine for the fuel economy, which is great if you don’t tow anything. Oh boy that’s where the train leaves the tracks in a hurry, buy which I mean it’s a thirsty mess. Great power, but big truck fuel economy! Just did a trip to the florida keys from Jacksonville florida, 7.5 mpg going down and 9 mpg coming back. I got the same mileage with my 2021 Chevy 2500 gasser. The only difference was that it did far better unhitched. 20mpg just putting around, big truck only got 15mpg.
          For a small turbo gas engine, it’s got impressive power, no doubt about it.

    2. Having several good conversations with current 2.7 owners the two gripes I hear about is the sound and noise coming from under hood and below expectations on fuel economy. One friend with an SLE 4 door 4X4 GMC says he cannot duplicate the 22 highway rating unless he’s going 65 MPH or less and another says around town and combined is also below what the sticker says. The power is never criticized and so far neither person has had ay engine related issues but that 8 speed transmission! That’s a topic for another conversation

      1. I believe MPG #’s are actually calculated at 45 mph.

        1. In found this about EPA testing:
          “The “highway” portion of the EPA’s gas mileage testing is only 765 seconds long, or just under 13 minutes of operation. Called the Highway Fuel Economy Driving Schedule (HWFET), it’s much more complicated than maintaining a steady cruising speed. Although its average speed is 48.3 mph, it calls for acceleration and braking across a distance of 10.26 miles, representing the surges and dips in speed that might be experienced during a typical highway run.

          The highway test is combined with the “high speed” test (also known as US06), which takes almost 10 minutes to run. It includes a number of additional accelerations and slow-downs (with the most dramatic being several climbs from 0 mph to above 60 mph, cresting at a top speed of 80 mph).

          Instead of relying on a fuel gauge, each vehicle’s tailpipe is connected to a machine that measures the amount of carbon in its exhaust to determine how much fuel was burned during the schedule.”

  19. Just commenting to say that I am a sales manager at a New Chevrolet store in the Southeast. We are one of the highest volume stores in our region. We cannot keep the 2.7’s on the lot and are begging GM for more. Our customers love them and our staff is trained on the benefits. Its was a slow start to get the general public to entertain the idea of a lowly 4cyl in a truck but now (at least in this area) it is absolutely a non issue.

    We haven’t had many complaints on it and have had way more issues with the 5.3s and and 6.2s and their lifters. Also the “amazing” 3.0 duramax has had more issues with emissions related complaints than the 2.7 has had all complaints. Again, this is my observation at my service dept. They spend all day, everyday, fixing GM products. Even though we have sold more 2.7s than any of the other powertrain options we have had less issues with the 2.7 than any of the other options.

    If the 2.7 was a diesel, none of these people would be bashing it. They would be praising it just as they did the 2.8 duramax that was in the colorado. Which is an absolute slug compared to the 2.7. The 2.7 makes almost twice the HP and around 90lbft more than the 2.8 duramax.

    And no, our customers aren’t all mall crawlers or grocery-getters. Some are for sure, but there are many hard working people who buy their trucks for hard work and make no complaints compared to their old 4.3, 4.8 or 5.3. We have several good customers who are on their 3rd and 4th 2.7s and continue to buy them over the 5.3.

    I personally have towed the same 7700lb travel trailer with multiple 5.3 v8s and 2.7s as well as the 3.0 duramax (last years with only 460lbft of torque) The 2.7 is a great pulling engine and feels very diesel like. It has all the grunt down low just like the duramax and doesnt “need” to wind out to 4500 rpm to shift like a 5.3 would.

    We often joke with customers that if we put ear muffs on you and have you drive a couple of trucks, and then have you tell me what motor is in which truck. You’d guess the 2.7 to be the duramax or the v8.

    My only complaint about the 2.7 and the complaint that I most often get is about the sound. It does sound like a 4cyl. But that’s it… None have blown up pulling a trailer, none have slung a rod through the block.

    I’ve seen them with over 100,000 miles run just as good as a new one.

    I personally believe is a very stout engine built for serious work. Just like a diesel. It just runs on gas.

    Just my opinions based on my real world experience at a Chevrolet store.

    1. I’m confused by this post. Are you saying it won’t last, but you also think the warranty is a joke? Or are you saying it will last past the 100k, so the warranty is a joke? Also, damn them for having faith in that engine and extending the warranty to match the longest available! Bastards!

      Reply
    2. I’m sure in 5 more years, once this engine has been out long enough… there will be plenty of examples of high mileage 2.7 engines. I can’t “spew” about 250k mile 2.7s because I personally haven’t seen any, YET. It has only been out a few years. Those are all similar issues that nobody brings up on the amazing diesels that have been out forever. Almost weekly I trade someone out of the service dept into a new truck who owns a duramax HD and has experienced injector failure or fuel pump issues. They’re facing replacing 8 injectors and thousands of dollars.
      I’ve seen it on low mileage trucks and high mileage trucks. Sure, the 2.7 may experience similar issues, but that is yet to be seen. My point is though, people love the duramax and for good reason. But all of the flaws that people like to point out about the 2.7 are basically the same flaws found in complex diesels. Yet no one bats an eye because its a diesel.

      At the end of the day, I’m just sharing my limited point of view. Where in my world we can’t keep them on the lot, and are begging GM to send us more. It’s been a great engine so far and I have no reason to believe that it won’t be just as reliable as any other GM engine.

      GM did a great job with this engine. And I will stand by that opinion. Don’t want or trust a complex and tiny 4 cyl in your truck? Don’t buy one. They still offer three other great engines to suit your needs, whether it be a true need or a comfort blankie for your ego.

      1. The money you save on gas will be outweighed by maintenance and or new vehicle sooner than 200,000 miles. The more complex something is the harder it is to fix or replace.

    3. Are your 2.7 trucks speced with brake controllers? For some reason in northeast Wisconsin most of the 2.7 trucks on the lots are not coming with brake controllers while most of the other powertrains are. This tells me GM doesn’t want people pulling the same things with the 2.7 as they do the other packages. That is a red flag for me, longer warranty or not.

      1. That reminds me of a couple of decades ago when A/C wasn’t standard on cars because they didn’t want you driving them when it was warm outside.

      2. We’ve had them come in when ordered in LT or RST trim with the convenience package with the power sliding back glass and other package options. GM likes to bundle the integrated controller with that package. Which for a long time wasn’t orderable… so we also had tons of 5.3 and duramax trucks coming in without the factory controller too, not just the 2.7s. However, all of the trucks including the 2.7s are prewired for brake controllers and have the connector tucked up under the dash by the steering column. Most even have the pigtail lose in the glove box to make it easier for the consumer to add one later on if they choose. So it’s very easy to add an aftermarket one that is plug and play through our parts dept or any aftermarket company no matter if you have a 5.3, 6.2, 2.7 or 3.0 diesel.

    1. Know what my problem is? I want the 10 speed and I’m not touching the 8 speed, revised or otherwise.

      GM can say whatever they want, they by their actions are positioning this engine as a weak choice by pairing it with their base trims and the crummy 8 speed.

      Reply
      1. Well, that’s a problem I have too. I don’t want the 8-speed transmission either. GM can claim the revised 8-speed is good all they want, but I’m not going to believe it.

        Reply
        1. I wouldn’t be too concerned about a revised and reengineered transmission or engine — I personally think it’s great when GM (or any manufacturer really) goes around the room to see where they screwed up and to find solutions.

          Case in point, the early 6T70/75 transmissions were absolute dog$#?!, but when GM revised them in 2013, the issues practically went away. New valve body, additional solenoids, new checkballs, removed pressure switches, installed new regulator valves, etc., etc. It went from a turd to a solid drivetrain.

          I’d say GM is doing something similar for the 8L90 and actually think it will end up being quite stout.

          That being said… yeah, no way am I touching a pre-revision 8–speed.

  21. For me it’s about max towing. I don’t like pushing things to the limit or past for long. When towing I try to keep it about 10% below maximum rating if I’m going far due the the strain not just on the engine but transmission and brakes. The more weight you try to stop the further the stopping distance. That distance increases dramatically the hotter those brakes get. The max on the 4 cylinder is 9500lbs. On the 5.3 11,300lbs and on the 6.2 13,400lbs. If you knock off 10% for safety that doesn’t leave much unless you are only doing light infrequent towing. If you have a pavement princess maybe the little four will work for your needs.

    1. Remember when the 2000 Silverado 2500 had a tow rating of 10,500? In all fairness though, that’s back when everything we hauled was a lot lighter.

  24. Here is the cold hash reality. The future of ice is in smaller and more complicated engines.

    With ever tougher emissions and CAFE number more small engines have to be sold to help off set more V8 engines being sold. If not limits will be placed on the V8 and more cost app,ied to them.

    These engines are very good but with poor results in past turbo engines lost trust. This is not desperation but more of GM showing confidence these engines will not be a problem.

    We had issues with 3.6 timing chains and with some transmissions but no longer warranties.

    My last turbo served me well and was very powerful for 10 years. I was never let down even with the GM tune pushing 23 psi of boost.

    The web also has a number of people who are not familiar or even experienced with recent turbo engines and they just repeat old talking points with little substance.

    Also if a turbo fails it Generates ton of reply’s. A V8 fails few post.

  25. For the people saying that the warranty is a marketing ploy to help sell the engine… obviously it is. And thats okay. Just one quick read of these comments shows that there is a large portion of pickup drivers who have reservations about this engine. Most exclaiming that a small turbo engine couldn’t possibly last in a big truck. So yeah, it makes sense that they would offer a longer warranty to help ease that concern for those of you who have it. A concern that whether valid or not, is a real concern for a big chunk of you. So it’s a barrier that GM is trying to breakdown.

    But the fact is, small displacement turbo diesel engines are used all over the world. Even the 3.0 litre duramax that everyone loves is tiny compared to the 5.3 or 6.2. But people love it. The difference is people will claim that the diesels are overbuilt to handle the excessive pressures etc. Well so is this little 2.7 gas engine. It is literally built like a diesel that uses spark plugs. Everything about it is overbuilt from a mechanical perspective. Designed to handle the excessive pressures just like a diesel is.

    In 5 years or so there will be thousands of these engines running the roads with high mileage.
