What’s your thoughts on the LM2? Thinking about buying a diesel Suburban or Escalade. Wife wants a newer car.

Work buddy bought the new Tahoe with the diesel. Looks like a nice rig. He said they claim 28 mpg highway but he hasn't got back to me on what it actually gets. I'll ask and let you know.

Main thing I’m apprehensive about is the oil pump belt. Seems like a dumb design.

We got a 2024 Tahoe with the LZO, there were significant upgrades to them in 2023 over the LM2. We’re perfectly happy with it. Gets the advertised mpg or better, did 30mpg on a recent trip to the beach and back from central wa. Plenty of power to rip around town with and on the highway, I personally wouldn’t tow with it, but I have a one ton Cummins for that.

I wouldnt worry about it. I think the new ones are good for 200,000 miles.

   I had one in a pickup, loved it until it blew up at 26k. Waited on parts for months and months from gm while it sat in the shop, finally got pissed enough to order a new truck. I understand that moving parts can fail prematurely on occasion and thats gunna happen but gm not having parts to fix in a somewhat timely manner is some real BS. Thats my 3.0 story. btw there was a couple other 3.0's in the shop waiting on parts too.

  Another thing to consider is the fuel economy is really good on these engines but when you factor in the additional cost of diesel, def, oil changes, mandatory factory fuel filter changes every 15k, ect all of that savings is gone. I ended up going 2500hd but if i was going to buy another 1/2 ton id probably just go with the good ol 5.3 :twocents:

I was close to getting a '23 AT4 with the 3.0 but some of the issues read about kept me away, along with poor dealership experiences. The motor did feel good on test drives, no doubt about that.

GM came out with a proper oil for the small diesels. I hope it helps but for now I'm not sure any of the small diesels are worth the trouble.

I really want to like the small D-Max but I have heard enough horror stories about premature failures and costly repairs on new low mileage vehicles to stay away for now. Haven't heard great things about the new generation of diesels in general. 

I have a 5.3 Silverado. Could use more power, my friend has the 6.0 which is much better power wise and both are known to be pretty reliable. Super easy to work on and I could replace the engine for the cost of a fuel injector pump or injectors on the d max.

Loved my old LLY d-max and have a LMM in my Camper. Both high miles with no issues.

I got the wife a 22' Yukon Xl with the 3.0.  We love it. It gets a legit 25+mpg in town and 28-32mpg on highway. Our trip with family of 6, all of our gear in rig and on the hitch extension platform to disneyland and back we got a total 28.3mpg hand calculated. 

It has plenty of power. We did have a coolant valve issue that had the rig in the shop for 5 weeks waiting on the part.  But that is our only issue and we have had it for 50k miles and almost 3 years.

I won't hesitate to buy another one when we get close to 100k.

I know two different people in the 70 plus age group that had so many problems with them they traded them in after less than 2 years

I've got a 2023 Silverado with the LZO engine.  Love getting 30mpg+ and also getting 17mpg towing a 5k lbs fishing boat out to Neah Bay.  Just like with larger diesel engines they like to be run.  The best MPG is when the engine gets up to temp and it needs some longer driving stretches to go through its regen process.  If your daily driving isnt a bunch of really short trips its a great engine.

exactly.
i had a 2019 colorado with the little 2.8 duramax.  loved that thing when i was commuting or using it on road trips.
my best was a 100 mile stretch averaging 35.6 MPG...anyways.
once i stopped with the longer drives when i started working remotely it was nothing but emissions issues and other sensors taking craps.
sold it back to a dealership for more than i paid for it brand new and picked up a used older gas 2500hd  for my tow rig...gas mileage doesnt really bug me since it sits mostly and i drive the 4runner when i go places.
all that is to say, i agree, make sure you are taking it on longer drives, not shutting down mid regen, etc.
