As GM continues to pursue its electrification goals, the 3.6L V6 LGX, one of The General’s longstanding internal combustion engines, is nearing the end of its production life.
First making its debut for the 2016 model year in the Cadillac ATS, Cadillac CTS, and Cadillac CT6 sedans, the 3.6L V6 LGX would later find its way under the hood of a broad swath of General Motors vehicles. Now, the naturally aspirated LGX powers just two U.S.-market models, and looking ahead, it’s likely the LGX will soon disappear completely.
The phasing out of the 3.6L V6 LGX is part of GM’s broader strategy to fully electrify its light-duty lineup by 2035, with major reductions in its ICE offerings already well underway. To that end, General Motors has confirmed that the Cadillac XT6 will be discontinued after the 2025 model year, leaving the ICE-based Chevy Blazer and Cadillac XT5 as the only remaining applications for the LGX.
What’s more, the ICE-based Blazer is also expected to sunset after 2025, further narrowing the LGX’s footprint. Meanwhile, production of the XT5 is expected to continue through at least the 2026 model year, but may very well mark the final chapter for the LGX engine.
The LGX is currently built at the General Motors Romulus Propulsion Systems facility in Michigan. In 2021, General Motors announced a $93 million investment for the plant – not to support the LGX, but to boost production of the GM 10-speed automatic transmission, used in the light-duty Chevy Silverado 1500 and GMC Sierra pickup trucks.
At present, only a handful of General Motors vehicles sold in the U.S. still offer a six-cylinder engine. These include:
- Twin-turbo 3.0L V6 LGY – Cadillac CT5 Premium Luxury (optional) and CT5-V (standard)
- Twin-turbo 3.6L V6 LF4 – Cadillac CT4-V Blackwing (standard)
- 4.3L V6 LV1 – Chevy Express, GMC Savana (standard)
- Duramax Turbodiesel 3.0L I6 LZ0 – Chevy Suburban, Chevy Tahoe, GMC Yukon, Chevy Silverado 1500, GMC Sierra 1500 (optional)
Notably, several other six-cylinder options have already hit the dustbin. These include the 3.6L V6 LFY, which was offered in the previous-generation Chevy Traverse and Buick Enclave, as well as the 3.6L V6 LGZ, which was offered in the previous-generation Chevy Colorado and GMC Canyon.

I purchased a 2015 chevy cruze in 2018 with 11000 miles engine and radiator had to replaced at 71000 miles does GM cover this on the powertrain warranty this was a certified used car sale
Most likely not. The car’s factory bumper to bumper and power train warranty would have already expire. The certified used warranty would only add an extra year on top of the factory warranty, and that factory warranty probably starts around 2015. The longest warranty would end in 2021 for the power train. That’s 5 years factory warranty plus 1 year CPO warranty from 2015.
Seriously? You bought a three year old used car six years ago and you want GM to replace the motor?
Better question is why post a question about the Cruze on an article about an engine that was never used in the Cruze. Put it in the forum John.
Personally, I think that Mary Berra is sending GM to it’s demise by insisting on total electrification!!
Agree!!
BOB W…..Ms.Barra is quite insane, you know.
Barra has never “insisted” on total electrification, that is totally false. Barra and all other GM executives have stated dozens of times that the path to electrification will happen at whatever speed consumers accept. They have stated ad nauseum that they will continually adjust their mix of ICE and EV’s depending on how fast the pace of electrification happens.
Then where are the new ICE vehicles? Barra’s killing Cadillac by dropping their ICE vehicles and replacing them with slow selling EVs
I have owned four cars, all of them GMs. I have no idea what I would buy from them currently, as I’m not interested in electric cars. If the Trailblazer or Trax were made here, I’d be interested. And if i were to buy an electric car, I’d be more likely buy a Tesla because it should be a choice to buy one, not part of an agenda by GM. Also, Teslas are made in the USA. Last year, in the Malibu’s last year of existence, it outsold the combined sales of GM’s eight electric cars. Dear kids, GM used to make (1) cars, not just trucks and SUVs, (2) with ICEs, (3) in the United States….
I have no use for an electric car. Even if I did, I wouldn’t buy one from Mad Man Musk.
Electric cars are out for us, as our home would require a major electrical system upgrade to support a charging station. The electric vehicles that would meet our needs are beyond our budget too. So, our Chevy Impala with a V6 and my Buick Electra summer cruiser will have to do. If I need anything, I will be looking for an ICE car with a V6.
Are you still using fuses and a gas dryer and stove? Heating with a coal furnace? I have not heard of any houses that cannot support a 240 volt outlet drawing 30 Amps, that is all you need for an electric car. All you need is a 50 amp breaker in your electric panel and a line to a 240 volt outlet, that is it, no “major electrical system upgrade”. Even any campground 240 outlet can charge an EV overnight easily.
My current Camaro that I own has the LGX engine. It’s an underrated engine, revs high, plenty of power, and decent on mpg. The engine also run with 87 octane just fine per the manual.
Because GM has already stopped putting a V-6 engine in the new Acadia…the 2018 Acadia I currently own will be the last GM product I’ll ever buy. Nissan Pathfinder or Ford Explorer with V-6 will be My next purchase soon.
Don’t forget the Jeep Grand Cherokee
Like a few others have said, I came from a life long GM family. Dad always had a Tahoe/suburban, mom’s on her 4th cadillac plus a former pontiac driver. I have an 04 xlr And a 19 silverado. If I had to go out right now and buy a NEW car, I think the only GM options I’d consider would be the XT6….and that’s it. I can’t think of anything else. Company has a 20 silverado that’s been junk, had a trailblazer rental that I’d never own, test drove a Sierra 3500, and liked the ride but the salesman told me they come standard with the “nanny” tech (and it would’ve been hard to custom order a diesel). My whole family is slowly moving to Chrysler products. And before there’s any sh!t, they’ve had far fewer problems with current (4 years old) Chrysler products than GM products…..
GM is pushing me to another brand, probably foreign. After many years of loyalty, full EV is not in my future and a loud four cylinder in larger SUV at 60K is not for me.
I have owned numerous GM vehicles over my 50 years of driving. (More than 20)
Not always new but reliable.
FROM CHEVY, OLDSMOBILE, PONTAIC, GMC, and with my 2 BLAZERS – 2021 and 2024, right now . With 4 dodge mini vans when the family was young. I also would consider jumping ship also to another brand.
I hope someone at GM reads this forum and realizes that they are destroying their own company, with poor quality products and EV’s that few people want.
If you were tasked with writing a playbook on how to destroy gm, you could not come up with a better one than how Barra is running gm right now.
So you must think Farley at Ford and Stellantis (currently have an interim leader) are far worse. As a Ford and GM stockholder I really wish Farley was half as good as Barra has been for financial performance. GM has crushed Ford and Stellantis in every measurable company performance category including sales and profitability.
Sales? GM always outsold Chrysler (stellantis) and Ford. But that margin had shrunk significantly. Farley is not much better but he seems to have the pulse of the customer far better than Barra.
I am with the majority…I will be looking elsewhere when the time comes. No electric for me. Sorry GM, we have been together for 40 years.
No One at GM Product Planning, Engineering & Leadership seems to care what the 60+ year olds who dont want 4 bangers prefer. There is manipulation of info or just no interest in what the older gen wants. The 3.6L V6 is a great engine just like the 3.8L 12 Valve was. Why are we PROUD to abandon a winner?? Guess there are Koreans or Ford. Please wake up
Fantastic motor. Sad to see it nearing it’s end. Glad I have it in my 21 RedlineTraverse. Wife love it and says we keeping it till it dies! I drove it today for Easter visiting family. I still love driving it.
Well GM expects a 2.5L turbo 4-cylinder to Replace a V6 on an even LARGER vehicle!!
These things are puking left and right on the new Acadia’s, engines locking up and turbos failing.
I recently took a long test drive of a new Acadia Denali with the 2.5, it had a little spunk but it was NEW with under 50 miles on it.
The engine noise in the cabin was hurendious! and Just normal driving on the 4 lane in SE Ohio you couldn’t get it to a speed where upon any kind of road incline it wasn’t shifting down with the 4 cylinder screaming then shifting back up.
Only to slowly lose speed and shift back down again.
This went on and on even with super cruise engaged. Back at the dealership i sadly walked away
Now add 50k, 75k or 100k miles IF it makes it that far! All I can suggest is IF you purchase one
Absolutely pay for the 100k extended warranty or once the powertrain warranty expires you may end up with a beautiful $50k+ vehicle sitting in your driveway with a crapped out 4 cylinder.
GM could absolutely care less about the customer after the purchase once their warranty expires.
GM engineers aren’t that Brite! Well maybe they are. IF it last at least until the warranty expires before she blows, the customer buys Another one🤬🇺🇲
