re: PSA: Do NOT buy a GM with a 6.2 engine

Done right, it would’ve been much more- a complete DFM-delete conversion imo. My local Chevy dealer only replaced the Bank 1 lifters (lifter in cylinder 3 collapsed), and then the catalytic converter.
I was already done with the truck and had a new one picked out, so I didn’t want to dig deeper into the repair. Just wanted out as quickly and cheaply as possible.
Kinda hated putting it back into circulation knowing more failures would likely occur, but I traded it in at another Chevy dealership who had the Tundra I wanted. Hopefully they get that engine right, or sell it heavily discounted with an extended warranty.

There is a reason I kept my old Tundra 5.7 even after buying a new truck this summer.

Yep, it was a great engine. My dad also had a 2002 5.3 Silverado and it was still running strong at 225k miles 15 years later. The interior of the truck had fallen apart but drivetrain was good as new.
The wreck i have mentioned before on here was in mine in 2015. Had about 130k miles and ran fine. Mine had the bench seat. Lucky we took it that night or we would likely be dead.

Should not be costing that much? How much is that much? A few hundred or $10,000?
Plugs should be changed at 100,000 miles. Might just be a bad plug or a coil pack. Might just cost a couple hundred.

Last November I bought a new Sierra 1500 AT4 with the 3.0 LZ0 engine. Made it a little over 10K miles and the entire engine needed replacing. Apparently there was a bad batch of camshafts in the earlier builds. Traded it in and paid the difference for a 2500 AT4HD with the 6.6 L5P

My last GM was a Silverado 2500 HD with the 6 liter Vortec. That engine was a beast but would bankrupt me these days with fuel prices.

The estimated failure rate for the worst engine (the 6.2) is something like 5%. The newer 5.3’s are probably close to the Ford 5.0 (1%). If I can save enough money, then bank on at least 6 years with 95% probability of no major failure, that math makes sense. And if the Ford lot is full of GMs, I should be able to save a buck. Reliability is not the only math people should care about. Also, currently own a GM with no problems. I won’t argue, they are not tops for reliability. But you can get a pretty good discount on a used one relative to a Toyota or Ford.

GOAT pickup truck engine.
They were horrible on fuel mostly due the the 4 speed transmission and 4.10 gears most trucks had. Man they would pull forever though, just couldnt pass many gas stations doing it. My old one got 14mpg if you tried really hard to get it there. Pulling a 24' stock trailer stuffed with cows down the interstate and you had to measure it in gallons per mile.

My 5.7 Tundra only gets 14.5 so that’s not horrible
Posted on 8/24/26 at 7:57 pm to biglego
Its pretty bad. I later had a ford F250 with a 6.2 gasser and 4.30 gears and it would get 17mpg if I tried to get it there.
Circa 2008-2009 driving something that averaged about 11.5 mpg was not pleasant.

The 3.0L diesel is something unique to others I think.
Agree. I just bought one and my friend has one as well. He’s over 60K miles with zero problems. We both drive a lot of highway miles. I’m getting 28-30 mpg on highway trips (200 miles) at 70-72 mph. Average of both in town and highway is 25 mpg. I did get the 100K warranty so we’ll see.

Just bought a Lariat with 5,0 V8 in June. I put in a bunch of research and was looking for about a year,

Meh, my motor locked up at 4 years and 50k miles. They replaced the motor and I have a powertrain warranty until 150k. Issue sucks but I have no issues with the way they’ve responded to it.

Turbo V6’s should be in half ton trucks
Had a 3.5 ecoboost, MPT tuned, in my last truck… went 170k trouble free miles.
3.5ho goosetuned in new truck, zero complaints. 550hp & 15mpg doesn’t suck one bit

I was scared of messing with my warranty so I just did the ford tune on mine. It’s not that impressive. I’ll do the goose when the warranty runs.

Prior to my GMC 1500 3.0 diesel, I had a 2020 Chevy 1500 5.3 with 175,000 miles. No issues at all. I did have all plugs and coil packs changed and fuel system cleaning for $700 at 125,000 miles. Other than that, it was just one battery and 3 sets of tires. Still had original brakes.

I'll be in the market for a half ton truck in the next year. Need it to pull a 25' bay boat two hours to my camp as well as loaded up with duck hunting gear in the winter. Was leaning towards the V8 AT4 until seeing this. Ford only offers a V6. Thoughts?
V8 will be offered in the higher trim packages for 2027.
I have the 3.5 and I tow a 22ft bay boat and all my duck gear during the winter and It does just fine. I also have 35’s on it.

I hate it when they do that. Offer the same damn drivelines in everything. It doesnt cost anything extra.

Angled Oil holes in the crankshaft?
More likely over chamfered oiling holes and oil only reliably shielding one side of each crank bearing.

So, what would be engine recommended for someone buying a truck right now?
