Seems like there's a big problem with GM's active fuel management on their 6.2 V8s which turns of half the cylinders when cruising.

“...disassembling the engine, and a portion of a connecting rod falls right out. The rod simply split in two...”

That has happened to two vehicles I’ve owned. One FORD one GM...........

The now use Dynamic Fuel Management which can vary the amount and location of cylinders disabled.

“Dave starts disassembling the engine, and a portion of a connecting rod falls right out. The rod simply split in two.”

When your unionized labor costs are essentially double what they would be without a union, then you have to CUT BACK in other places in an attempt to price competitively against non-union competitors. Obviously this includes engineering and material selections, along with many other areas.

It’s simply time for the unions to go. 100 years is ENOUGH ALREADY.

A friend just purchased an electronic de activator for his 2013 Escalade so it runs on 8 all the time.

He says that it works well.

Imagine how angry the guy was when he found out that his warranty had already expired. Just kidding...sort of.

GM - engineers and workers are too woke now to make and assemble combustion powered engines. Go woke, go broke. The problem is mostly in the lubrication galley design or lack thereof. The bearings get starved for oil and burn out, which brings on catastrophic engine destruction which makes repair no longer cost efficient so an entire engine replacement is necessary. There are so many engines going down, factory replacement engines are taking months to obtain. It’s one huge mess and it may spell doom for the GM vehicle division, especially in the truck division where working trucks can’t sit idle for months.

Was it still under warranty? Or did that expire at 3 miles?

Our daughter’s 2019 Ford Eco-Sport blew an engine due to a long known oil pump issue. Ford replaced the engine. My own FordFocus has had three warranty clutch replacements due to a well known design transmission design flaw.

The Saturn 5 moon rocket designed and built some seventy years ago was likely one of the most complex machines ever built and performed almost flawlessly. It was designed by real talented engineers with little more than slide rules. Are there no real engineers these days or just DEI hires?

Companies used to take pride in the product they turned out.

Management took pride.

Workers took pride.

Government didn’t try to run the car companies.

The Democrat party didn’t try to run the car companies.

Lawyers weren’t everywhere.

It is so sad that GM dumped their most reliable engines for this poorly designed crap. For instance the 3800 was considered about the most reliable and long lasting engine ever made for passenger cars and they dumped it. The 3800 did have some problems in the later versions, but they were easily fixed. The series one was bullet proof.

How could that have anything to do with a broken connecting rod?

Several possibilities. But overseas sources Chinese counterfeits are a likelihood. Making connecting rods from substandard metal but stamping it as a higher level hardness is not uncommon.
