GM is recalling nearly 600,000 SUVs and trucks in the United States due to engine issues, it announced Tuesday.
The Detroit automaker is recalling 2021 through 2024 model year Cadillac Escalade and Escalade ESV, Chevrolet Silverado 1500, Suburban, and Tahoe, GMC Sierra 1500, Yukon, and Yukon XL vehicles with 6.2L V8 gas engines.
It said the connecting rod and crankshaft engine components may have manufacturing defects that can lead to engine damage or failure.
GM said it identified 12 crashes and 12 injuries in the United States that may be related to the recall issue. Dealers will inspect the engine and, if needed, repair or replace it.
Vehicles that pass inspection will be provided a higher viscosity oil, which will also require a new oil fill cap and an oil filter replacement, GM said.
The National Highway Traffic Safety Administration in January opened an investigation into 877,710 GM vehicles over reports of engine failures involving vehicles with the V8 engine.
The company subsequently opened its investigation.
GM previously closed three prior investigations into the issue since 2022 based on the available safety field information.
It identified 28,102 field complaints or incidents in the United States potentially related to failure of the engine due to crankshaft, connecting rod, or engine bearing issues, including 14,332 involving allegations of loss of propulsion.

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.
I don’t think these very low viscosity oils have enough support for connecting metal parts. But I’m no engineer.
Government regulations including EPA reg. made them make changes not compatible with longevity.
“Government regulations including EPA reg. made them make changes not compatible with longevity.”
Which regulations affected those components? Hard to imagine any. So I’ll stick with DEI, specifically incompetent people making the small decisions that can ruin the end product, such as which metal alloy to use...seen that first-hand.
Wouldn’t have a GM made vehicle if you gave it to me.
Whew! That's going to hit the poor in the projects pretty hard.
Curious minds want to know where the substandard parts were manufactured.
Overseas ? Likely. China ?
EV motors have less parts and therefore less failure modes than gas engines. Tesla’s really don’t have a transmission either so that’s another major subtraction of failure modes.
I talked to a guy who had a 2014 59000 mile Chevy 1500 with a 6.2 gas engine. The truck was like new. He was driving it to a dealership to trade it off on a new one. The engine blew up on the way. Valve spring broke and there was piston to valve contact and total destruction. New engine was 15k.
Aluminum engines
Aluminum Engines are the direct result of EPA MPG mandates.
Anything to reduce weight and increase EPA MPG.
“Which regulations affected those components?”
CAFE standards. The “super cruise”, or whatever they call it, doesn’t allow for adequate lubrication of the engine components while it’s engaged.
Or so I’ve heard.
L
The basic one is the CAFE mileage requirement constantly increasing. Lots of minor and not so minor changes year to year in order to meet that. For GM, the most obvious are AFM, and auto stop/start.
I say it’s DEI until proven otherwise! It’s time we start playing by DNC rules.
The lower viscosity oils are not the issue. The issue with these GM engines is their Active Fuel Management (AFM) system which deactivates cylinders in the attempt to increase fuel economy. Their AFM system is completely defective and almost every GM engine with it has failed or will soon fail.
What do you expect from “Government Motors”?
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?
So? Millions upon millions of cars have done this country just fine.
“ don’t think these very low viscosity oils have enough support for connecting metal parts. But I’m no engineer”
I agree, the 0W-20 seems awfully light weight for a, in my case a 5.7 lter Tundra V8. However, the 5.7 Toyota V8’s are very reliable, unlike the V6 dual turbo engine that replaced it.
I won't buy any vehicle with a turbo especially 4 bangers. I'll buy a 20 year old vehicle with a 100,000 miles on it first.
