General Motors is now the subject of an NHTSA investigation after more than a thousand complaints were logged over sudden and catastrophic failure of some of its “L87” 6.2-liter V8s—a core power plant for Cadillac, Chevy, and GMC trucks. It’s actually the latest in a string of uncommon but linked reliability problems to impact the 5.3- and 6.2-liter small block families over several recent model years—a notably bad run for what’s supposed to be an uncomplicated, naturally-aspirated V8 engine.

Oh well if that’s all.
Kinda crazy that GM has been making some version of that “small block” pushrod V8 since like the 1950s, and it’s still unreliable? The damned thing should be perfected by now, right??
Buy a Chev, you’ve bought the best!
You’ll drive a mile, then walk the rest...
It's time to ditch CAFE standards so we can have uncomplicated, reliable powertrains again.
All of this green crap they've forced automakers to embrace has resulted in lighter components that fail prematurely.
They were told to make EVs and then make ICEs crap
This could well end General Motors as a corporation. If what you build is unreliable, NOBODY will buy it.
They aren’t giving them loaners?
In the collector car market, number matching is a big thing.
Because of CAFE, they sacrifice a lot of reliability to save a little weight. It is insane. It is like building bridges with no safety margins.
Might not be the most popular opinion here but I will never buy a car from an American manufacturer. The big half ton 4 door pickups are very popular in the PNW where ILive. All my friends who own them have had catastrophic failures with either the engines, Trannies, or the fuel system on the Diesels. Time to let the “big three” die on the vine on their own from their constant failures and bailouts. We survived without Holden, Studabaker, and Nash.
GM has been engineering their engines and transmissions to last only 100,000 miles the last few years. This was said by a dealer here when ours went bad at 106,000. Just out of extended warranty range. They want to sell more trucks faster.
Heck. Even Cubans can keep 70 year old rust buckets on the road.
Don’t know details of these engine problems but if I had to bet manufacturing defect on part or parts.. Honda, Toyota etc have all been hit lately with this sort of failings as well.
Cost cutting comes at a price
Serves them right for acquiescing to the socialist Obozo instead of allowing the Invisible Hand to control the market.
Enough to make you go electric.
I will not buy a vehicle built by the UAW. That’s not a popular position here either.
Probably Chinese sourced parts.
They could also be using roller-rockers which have been having problems with needle bearings.
When the bearings fail the bearing rollers fall into the engine and cause havoc.
Just like All American manufacturers do these days with Brakes. They make the Brake Discs (Rotors) just above the Minimum thickness so you can’t Turn (Resurface) Shops won’t do them any more because of the liability factor.
Parts stores will not do them either so unless you have a Brake Lathe and do them yourself you’ll have to buy new ones.
I call it Planned Obsoletion.
I would second that.
They are being forced to do all kind of modifications, to reduce fuel consumption by tiny bit, but the product suffers.
They put on my Jeep this stop engine “feature”. I hate it and I am not sure if it saved me a gallon of fuel or not.
But is cost me $400 to replace.
