Well, all their EVs are missing one.................

“It said the connecting rod and crankshaft engine components may have manufacturing defects that can lead to engine damage or failure.”

About the most basic components of a traditional car.
That’s what DEI gets you...people who think they know better than 100+ years of gasoline engine design. All they had to do was stick to what they know works.

[BipolarBob]

I don’t think these very low viscosity oils have enough support for connecting metal parts. But I’m no engineer.

[TTFlyer]

Wouldn’t have a GM made vehicle if you gave it to me.

[Tell It Right]

The Detroit automaker is recalling 2021 through 2024 model year Cadillac Escalade and Escalade ESV

Whew! That's going to hit the poor in the projects pretty hard.

[chiller]

Curious minds want to know where the substandard parts were manufactured.

Overseas ? Likely. China ?

[dfwgator]

What do you expect from “Government Motors”?

[ZOOKER]

To replace the connecting rods and/or crankshaft is a major operation. Removal and total disassembly if the engine required.

Even inspection of these parts (without replacing them) is a big job. Lots of time and money involved here.

Just wondering: if they recall your car and you don't bring it in, can they void your warranty?

[Celtic Conservative]

I will keep my 16 year old car that runs and drives perfectly, thankyouverymuch.

So you put heavier weight oil in. Wonder what the life expectancy of these bum motors are. As long as they pass warranty I guess.

It said the connecting rod and crankshaft engine components may have manufacturing defects that can lead to engine damage or failure.

Cast pistons
Powered iron rods
Powered iron crankshaft

What could go wrong bonus problem fast high heat cycle shrapnel ensues.

[enduserindy]

I read the other day GM doesn’t have enough engines for warranty work already..

[Lockbox]

Vehicles that pass inspection will be provided a higher viscosity oil

Thin oil is the issue (prevention).... who knew??? Guess 0-16 weight oil can be interesting.... MMM Toyota?

[eastexsteve]

A heavier weight oil is not going to fix this issue. It’s just going to quiet it down a bit once those rod journals start to wear prematurely and start making noise. If you own one of these turds, then sell it fast!

[oldtech]

In the meantime, I have an older 3800 engine with quite a few miles on it that shows no signs of giving up. GM used to build many good engines. Did they forget how it was done?

[equaviator]

"GM said it identified 12 crashes and 12 injuries in the United States that may be related to the recall issue."

For that they recall 600,000 vehicles? This "abundance of caution" makes me skeptical if not suspicious.

Now do the 5.3L engines. That AFM system and lifters cost me a bunch of money. https://i.ibb.co/d4m6QFNs/IMG-3473.jpg

[eastexsteve]

Aluminum blocks are fine. 20wt oil is fine for non-turbo cars that call for it. Turbos are fine. I've seen turbochargers outlast every other component on the engine. I've seen many, many cars with all of these components do just fine to almost 200k miles. I personally just sold a car with the above-mentioned components that had 179k on it. Just keep them properly maintained.

However, I have seen this issue before with GM back in the early 1980's on big block engines. Undersized rod journals and/or soft crank/rod bearings.

[monkeyshine]

Why just their 6.3L and not the 5.3L? What’s different about the crankshaft and connecting rod in the 5.3L? Just the amount of torque pulling on these parts?
