They’re finally looking into the 6.2

My loyalty is to stands behind their products, good or bad, and take care of those who stood behind them. As of right now, GM ain’t doing that. It’s the unraveling of their brand and is ultimately their path to bankruptcy. Again.

Totally. GM is also not alone. Toyota went to $#it too. In the end, the ultimate blame lies solely with the EPA.

Shared responsibility. EPA for pushing the efficiency initiative as unrealistically as they have. On GM for faulty design and/or part quality controls.

Over bored lifter, bad main bearings, etc isn’t an EPA gig.

I've been saying this for years. If you want GM reliability, you are stuck with 2006 or older. Anything newer, unless you lose certain things in a boating accident is a ticking time bomb. It's not just the engines too. Youre Lucky to get 150k out of the transmission.

I'm also not big into warranties. More often than not, the dealer will do everything they can to turn it into a no warranty issue. If you want reliable you have to buy reliable. Not junk and then get a warranty because you know it's junk and youll need it.

If I were in the market for a 1/2 ton truck, I am absolutely not buying any V6 turbo charged junk. V8 gas only. Staying far away from 2007+ GM 1/2 tons. And if it's newer it'll have to be either a Nissan Titan or a 21 and older Tundra.

I currently have a 2004 GMC Sierra with the 5.3 and have 320,000 miles on it. Nothing has gone wrong, bought it new. I’m thinking of replacing it but now I’m not so sure.

It'll of course be up to your personal preference in the end.

The reason why I push Titans so much is because I know many owners to include my in laws. Every single one swears up and down by them. They are also the only manufacturer to offer a 5 year 100k bumper to bumper with no additional $$$. Can't beat that. Look at the Titan XD too. It's halfway between a 1/2 and 3/4 ton.

You also won't be dealing with cylinder deactivation or start stop trash.

The cons? They're discontinued after 2024. But you can land a solid deal on a brand new one right now for what is left over. Shop around. I think there are still some dealers offering 0% for 60 months.

The Titans may be reliable, but they look so fugly. I'm not a fan, and wouldn't own one just for their looks.

To each their own. I don't mind the look. I'd agree it's "dated" looking.

Just my own personal opinion. No disrespect intended.

 

[RebelDS]

I always assumed that most stayed away from titans due to horrible mileage. If getting terrible mpg isn’t an issue, then they are something to look at I suppose. At my company we just got a brand new frontier. Got a 76 year old dude driving it who drives it easy and it gets horrible mileage too. So bad that we think something has to be wrong with it

Hopefully this will bring light to what’s causing these failures.

I traded a 2012 Tundra with 222,345 mils, still running strong. I would not go back with a Tundra because of the new six-cylinder turbo engine. They lost me as a long time customer. If I’m gonna own a big truck, I wanted a V8.

Now I have to worry about engine failures on an $87,000 truck. I will buy that extended warranty just before the 12k

It seems no matter who you go with, there’s always issue. Tundra is having their share engine failures. The only difference is that GMC has had this engine out for a long time, and should’ve worked out all the issues.
Where Toyota has a totally new design engine and still working out quality issues.

In all my years of owning vehicles, I can count on one hand how many times I’ve purchased extended warranties. At the cost of these vehicles today, I wouldn’t dare to NOT buy an extended warranty.

Found this on the gmc authority forum hope it helps. Still researching for more info.

31,169 miles on my 2023 Sierra AT4 with the 6.2L. Engine seized going 50mph....so making my way to the side of the road on a narrow road with no shoulder in rural MN with a dead engine (limiting braking ability) was fun. Metal all in the oil, and there have been exactly zero engines available in the entire world (well not for warranty use, there are plenty of them being put into new rigs on the factory production line so....), so the truck I bought 2.5 months ago is sitting there with absolutely no ETA. Class action is coming I'm assuming.

same thing 43,0000 miles on 2022.5 AT4 6.2 ,Motor locked up doing 80ish on Dec 17th called yesterday . i was told nothing yet looks like it has not moved yet they told me! GOOD TIMES!

Bobo57, I totally agree with you but if they want to do something, an extended warranty would feel good. My 6.2 has 50k on it and no issues and love it.

I have 68k on mine and still going strong.

Man that sucks….
