Diesel Appropriate?

[contenderv07]

Hey everyone, I'm looking for some opinions.... My wife is looking to get a Yukon, but I'm trying to decide if it's "safe" to get a diesel or not. She works from home and travels MAYBE 10 miles a day. The one thing I worry about it the regens since she doesn't travel long enough to really burn it off until maybe the weekend. I've had 3 diesels but none of them had any emissions so this is out of my wheelhouse. Let me know what yall think

I wouldn't go diesel for that type of driving. You will end up having issues I believe. The new diesel systems aren't like the OG setups, they need long stretches to keepnthe catalyst hot.

She probably just needs a Chevy Bolt. LOL

thats what I was thinking too (about the bolt LOL). If these things didn't have any emmisions on them, I'd be all over it, but I also know diesels are meant to be driven long distances. In saying that, would the 5.3 be ok, or get the 6.2?? I would really like to turn the cylinder deactivation off if we get gas

Get the 6.2! Whatever you get, get a battery tender as the battery will become depleted from the short hops and sitting so much.

... In saying that, would the 5.3L be ok, or get the 6.2L?

If you need your vehicle to work (or play) HARD, 6.2L.
If you only need it to go places and protect yourself from bad weather, 5.3L is ok.

I would really like to turn the cylinder deactivation off ...

Good, do that, even if only by using a plug-in of some sort.
(A tune is better bang for the buck, lots more fun, AND the transmission will last longer before its rebuild too.)
Turning off lazy cylinder mode, and changing oil sooner than the Oil Life Monitor suggests,
will keep the lifters as healthy as reasonably possible for as long as possible.

At 10 miles a day, I know I would be looking at a Hybrid or a EV. Toyota Highlander Hybrid, Lexus Hybrid/EV, Chevy Bolt/Blazer EV, Tesla Model Y/X, Rivian, etc.

Diesel is out for what was mentioned above. It needs stretches to get the SCR/Catalyst hot.

And I would not be buying any gasoline product from any of the big 3 right now.

thanks everyone! I wish we could get something smaller but we have to have a large SUV. I've got a 2019 Tundra that I'm going to run in the ground because that engine won't die. Its hard for me to get anything that these newer SUVs have, with turbos. They just scare me

Please, for the benefit of those gathered, do expand on this statement?

No need to be scared of turbos, if you can avoid them easily enough.
Might be difficult to avoid them once the GMT800s & GMT900s age into extinction ...

Rivian is considered a large SUV, has 3 rows.

A Toyota Sequoia is a large SUV with 3 rows.

A Lexus GX or LX is a large SUV, but I agree about the V6 thing, especially with the recent recall. Maybe look for one that is a V8?

GM's AFM/DOD is a junk system, has been forever. Add in the lifter issues that GM has been having, and this problem is still on-going. Its a no go. The 3.6HF engine has, and will always be a junk engine. On both of them, when you factor in GM's Planned poor maintenance schedule (OLM of 10k miles or more), I just cant do it, and I dont recommend anyone else do it.

Ford going strictly V6 turbo is a bit of a annoyance for me. The 3.5 is actually a good engine when in a RWD based platform. But in the FWD based platform, is just junk. Fords problem is usually around poor electronics, and transmissions when talking about RWD Platforms.

Dodge/Stelantis was ok for awhile. The Hemi is, and has been, a decent engine. But now they are going strictly I6 Turbo, and having really bad growing pains doing it. Give it a couple years, and they may figure it out. But not right now.

I will grant you that you can always not go by GM's OLM, and do normal maintenance like we used to do in the old days... People just dont do that anymore. They wait for the car to tell them that service is due, or that a tire is low, or... For the OP, whos wife only drive 10 miles a day, I can see nothing buy headaches from this, and a lot of them.

But this is just my opinion. Been a GM die hard loyalist since I stole my first car way back in the day. Up until my Rivian, it was pretty much all I owned.

And no I am not advocating for Rivian, Its an ok truck. But still not what I would prefer to drive. Miss my 2006 Esky, love my 2004 Envoy.

GM's Engine Half @$$ was a bad idea, and its implementation was far worse - weak @$$ parts.
GM's Cylinder Confusion (SEVENTEEN firing orders!) was a meh idea at best,
and once again, its implementation was far worse - weak @$$ parts.

Cylinder valve deactivation NEEDS far higher quality parts to last and work properly for 300,000 miles.
Since labor and parts costs are always being driven DOWN,
and carmakers are actively against the idea of a vehicle lasting 200,000 miles,
Cylinder valve deactivation will NEVER be a proper long-term solution.

Oil Life Monitor works just fine, IFF you change oil & filter sooner than 15%.
Try 20%? 25%? 33%? 50%? Easy enough solution there.

Eventually 6-inlines (and 4-inlines heavily based on them) with more stroke than bore
will be the most common of the last internal combustion engines.
Hopefully they'll be twin (triple?) turbo'd, with hydraulic hybridized regenerative braking.

Meanwhile, I'm waiting for roller skates with some assist ...
