According to a report by The Fast Lane Truck, General Motors notified Chevy and GMC dealers on Friday, Aug. 27 about the diesel engine's availability.

A friend recently bought a GMC diesel, inline 6.
He loves it. Average 31 mph on a short trip. Can't tell it a diesel, no noise no smell.

Is the 3.0 L an inline 6?
3.0L

Ive heard that many truck makers are waiting for semi-conductors to manufacture chip boards to complete their trucks? Many supply shortages right now in all sectors due to reduced staff and slower production efficiency because of past and present nnalert protocols. Not saying they didnt make the right calls but we will need to remain patient until the pandemic is deemed over and its full steam ahead at the assembly lines again.

Ask a www search engine the question. I saw a chevy ad and decided to see what the 2.8L Duramax turbo was all about and got the full story, parts sourcing, reason for this and that. Its a 4 cyl.

It's possible my friend thinks he has an inline 6 and he has a 4 cylinder.
I really don't know..

Yep, simple search results are 3.0L in-line 6, 277 hp & 400 #/ft torque, rated 30 mpg in 1/2 ton & 3/4T trucks.

GMC 3.0L Duramax is an INLINE SIX CYLINDER ENGINE developing 277 HP and 460 lb-ft of torque. 95% Tq @ 1250 RPM and 100% Tq @ 1500 RPM. If anyone should ask, it's an INLINE SIX CYLINDER ENGINE. That, I will add, I have absolutely no interest in because it's being built in Michigan by GMC. Was also designed by GMC.

My work bought two of them recently. One is at the dealer getting the engine pulled because of some sensor causing a no start issue.

I would not buy anything gm builds currently, anyway. gm has massive quality issues currently. They think they will be a leader in EVs, but can't even keep a simple hydraulic lifter working to the first oil change. Their current EV has had to halt production, and tell current owners to park them outside, because they are spontaneously catching on fire.

This stoppage will keep the potential buyers from the heartache of owning what is likely to be a short lived engine. I look for them to go away, as the market is shifting. Ford discontinued their baby Powerstroke, orphaning all the models already on the road. The Ram EcoDiesel is getting a reputation for spun main bearings, leaving owners with what amounts to a totalled vehicle when the engine fails.

Have to wonder why anyone would incur the cost and lack of reliability of a tier IV diesel in a light duty application ?
If the emissions regulations were tier I or Tier II, then sure they maybe worth consideration .
Just wait for the extra problems when Tier V regulations are enacted .
GM developed the 401 HP 6.6 DI gasser because they thought h I l l a r y was going to win and enact Tier V ,
Four years sooner .

Anything with DEF is going to be a money pit,sooner or later. We had a Kenworth Paccar go down last week(bad sensor) around 40,000 miles. Mine went down yesterday, 68,000 miles and two years old.Bad sensor,national back order. Warranty is not worth much when you can t buy parts.

The only 4 cylinder offered in GM full size trucks is a gas engine. The LM2, 3.0L I6 duramax has major design issues, I really doubt it's all about a supplier shortage. They also have big problems with gas engines and transmissions too. It's not all GM either, do your own research if you are in the market, especially if you are concerned about longevity and cost to own.

I'm not talking about antique gm, I'm talking current production. My BIL has a 2021 Sierra. Transmission failed AND lifters broke, before its first oil change.
