General Motors has issued a recall of some 2021-2024 full-size trucks and SUVs equipped with the 6.2L V8 L87 engine in Canada. The recall concerns manufacturing defects that can lead to loss of propulsion, engine damage, and engine failure.
GM’s decision to issue a recall follows a series of lawsuits, investigations, and engine replacements regarding consistent problems with the 6.2L V8 L87 engine.
The automaker provided us with the following statement: “GM will voluntarily recall certain 2021-2024 Chevrolet Silverado 1500, Tahoe, Suburban, GMC Sierra 1500, Yukon, Yukon XL, Cadillac Escalade and Escalade ESV models equipped with 6.2L L87 engines to resolve manufacturing issues affecting some engines. The safety and satisfaction of our customers are the highest priorities for the entire GM team, and we’re working to address this matter as quickly as possible.”
The problem: GM notes that the connecting rod and/or crankshaft engine components in affected vehicles may have unspecified manufacturing defects.
The hazards: affected engines with manufacturing defects in the connecting rods or the crankshaft can lose propulsion and ultimately lead to engine failure, increasing the risks of an accident.
The fix: Trucks and SUVs affected by the recall will be inspected for manufacturing defects. Vehicles that pass inspection will receive an engine oil and filter change, this time using high-viscosity 0W-40 Mobil 1 Supercar oil. The owner’s manual for L87-equipped trucks calls for 0W-20 oil. The oil fill cap will also be replaced (to reflect the new oil type). If it does not pass inspection, it will be repaired or replaced as necessary.
Affected components:
- Connecting rods
- Crankshaft
- Engine oil
- Oil filter
- Oil fill cap
Affected vehicles:
- 2021-2024 Chevy Silverado 1500
- 2021-2024 Chevy Tahoe
- 2021-2024 Chevy Suburban
- 2021-2024 GMC Sierra 1500
- 2021-2024 GMC Yukon/Yukon XL
- 2021-2024 Cadillac Escalade/Escalade ESV
Number of affected vehicles: A grand total of 49,848 vehicles are impacted in Canada, all equipped with the 6.2L V8 L87 engine. That’s in addition to the 336,756 SUVs and 260,874 pickups recalled in the United States alone. Models listed above powered by the 5.3L V8 L84, turbocharged 2.7L I4 L3B, 3.0L I6 LM2 turbodiesel Duramax and 3.0L I6 LZ0 engines are unaffected.
Owners should: GM will notify owners of affected Silverado and Sierra trucks. Additionally, The General has placed a stop sale on affected pickups currently in dealership inventory, meaning they cannot be sold, delivered, used in demonstrations, or traded to other dealerships until they’ve passed inspection and received the appropriate oil change. The trucks that do not pass inspection cannot be sold or delivered to customers.

HABBEMOS MAMMA …. Make.AmerikaGreat.Heiliger.Again !
a blonde would be greater but
Another weird comment from China
I’m not sure how this is an appropriate fix. If there are manufacturers defects but the engine passes inspection all that is required is an oil change??
From other articles I’ve read the inspection is to read for a stored code about alignment of the affected components.
A change in I’ll viscosity will not fix this only prolong its inevitable failure. It will however have an immediate drain on our finances as the new oil is the same oil used in Corvette’s. Basically doubling our cost per oil change now according to my GM dealer.
I can see a lot more lawsuits happening in the future because this is NOT an acceptable fix!
Íf it’s running fine for two or three years the engine is fine I see plenty of these trucks on the road yet. Even if it’s new this was happening with less then 10,000 miles on the trucks this is something your engine can fend off for very long before it goes pop! What I really don’t understand is this goes all back to 2020 what did people just park the trucks and wait for a fix!? And no an oil change won’t fix this but if the wrong has been used in the engine it should be changed over to the right weight….why a Corvette gets a heavier grade oil then a heavy truck that’s hauls and towes with 4WD is somebody’s mistake or they where trying to save gas money by using a lighter weight oil. For me myself I would never worry about this because I’ve always liked the 5.3 literally V8 better anyway I don’t need the bigger engine just tó carry myself in half of the time.
This article states “GM notes that the connecting rod and/or crankshaft engine components in affected vehicles may have unspecified manufacturing defects.”
A previous article again from GM Authority states: “The investigation uncovered two main culprits behind the failures – first, there was evidence of rod-bearing damage resulting from sediment contamination in the crankshaft oil galleries and connecting rods. Second, some crankshafts produced during this period exhibited out-of-spec dimensions and inadequate surface finishes. These combined flaws can lead to accelerated bearing wear, which in turn may cause severe engine damage or outright failure.”
I still do not understand how an oil spec change will “fix” bad parts.
*can’t fend off*
First vehicle at age 15 was a 1965 El Camino with a 327 followed by numerous other Chevelles with 283, 350, 396. Camaros with 350 and a Monte Carlo SS with a 305 HO. Never in my life have I had any trouble with a gm small block. This is sad as government regulations have made engines too complicated for a little better mpg or emissions.
Something smells really bad about this whole thing, if you change to the higher viscosity oil to possibly mitigate your damages your warranty will be void, but if the inspection shows no problem you get the higher viscosity oil change?
What about 2020 L87 engines or earlier are they not made at the same engine plant with the same components I am pretty sure they are !
Bought a new Denali 1500, paid cash for it, go to pick it up and you can’t take delivery because of a recall. Image a world of being p’d off and double it. Especially when the dealer shrugs their shoulders and says they can’t do anything.
I thought the 2025’s were not included in her recall?
Or was this a left over 2024?
Failure at 10,000 miles means someone is in big trouble – they weren’t supposed to fail until AFTER warranty expiration. And as I’ve pointed out with GM many times before, this is as much of an art as a science. Of course GM knows how to make a solid V8 engine, 100 years experience proves that. They also know how to make Ignitions. GM’s Elephant 🐘 Management required engineering-in Failure to occur as close to expiration of warranty as possible. The problem is too many cooks in the GM Kitchen; do we choose inferior alloys, do we design-in tolerances that ensure Failure, do we recommend inferior lubricants and restrict airflow and coolant flow to at least a few cylinders. One thing is very clear, GM failed yo speed up their Odometers as Tesla now does to avoid warranty claims and from the designer of the very special K!ll!ng Ignitions, that’s unforgivable.
Talk about destroying brands…
So there are three blaring issues here.
1. Oil viscosity will not fix defective parts, at best it may prolong time to inevitable failure.
2. Customer is to absorb the doubling of oil change costs going forward?
3. Decreased value of these vehicles on trade/used car market.
And they wonder why people are opting to purchase foreign vehicles.
