Some 2021-2024 Chevy Tahoe, Chevy Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV full-size SUVs are included in a safety recall issued by General Motors. The recall refers to a problem in which the 6.2L V8 L87 engine has 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: Chevy Tahoe, Chevy Suburban, GMC Yukon/Yukon XL, and Cadillac Escalade/Escalade ESV units 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 models calls for 0W-20 oil. The oil fill cap will also be replaced. It’s unclear what happens if an affected SUV does not pass inspection, but it’s likely an engine replacement.
Affected components: connecting rods, crankshaft, engine oil, oil filter, oil fill cap.
Affected vehicles:
Number of affected vehicles: 79,747 Escalade units, 46,280 Escalade ESV units, 22,162 Suburban units, 44,802 Tahoe units, 82,832 Yukon units and 60,933 Yukon XL units are affected by the recall. That’s in addition to 107,244 Silverado 1500 units and 153,630 Sierra 1500 units, for a grand total of 597,630 vehicles impacted in the U.S. They are all equipped with the 6.2L L87 V8. Models listed above powered by the 5.3L V8 L84 or 3.0L I6 LM2 turbodiesel Duramax engines are unaffected.
Owners should: GM will notify owners of affected SUVs. Additionally, General has placed a stop sale on affected SUVs currently in dealership inventory, meaning they cannot be sold, delivered, used in demonstrations, or traded to other dealerships until they’ve passed inspection and gotten the appropriate oil change. The SUVs that do not pass inspection cannot be sold or delivered to customers.

Mary Barra ceo, should be ashamed of herself. The highest paid ceo in Detroit, and all they make now is crap too. Have been a lifelong GM customer, currently driving 2 Cadillac Cts, one coupe and a Vsport Sedan. Were looking to replace them soon, but GM makes not one thing we are interested in. Dont want a pickup, and certainly dont want some wheezy 3 or 4 cylinder boxy suv, with no style. All Barra worries about is making bank; thats it. At this rate these will be the last GM vehicles.
Ok what about the older 6.2 We had a 2011 GMC Yukon Denali I had the lifters replaced 4 times so also the older engines were having this issue.We traded our Denali in for a 2018 Equinox what we traded it in 1 year later for a 2023 Traverse LT, are we going to get any money for our repairs?
I’m assuming the DTC P0016 code would cause the Check Engine light to illuminate? So aside from changing to the new recommended oil…does anyone know how long the recall will be in effect (covered by mfr) in case of future failure
Have the '25s been left off the recall list because GM 'fixed' the manufacturing defect, or because they'd rather wait for that batch of nightmares to catch up with them down the road? A lot of the '25s were made in '24, so what gives?
Frightening band-aid - more viscous oil? Wow, just wow. Kinda like hoping as a kid on a budget that dumping STP or Marvel Mystery Oil in your worn out '67 Tempest back in the day might "fix" those cavernously worn main & rod bearings & quiet her down a bit for the next big date. Mechanical engineer and lifelong car nut here with 35 years in the auto industry - grew up with GM - '65 Tri-Power GTO in high school (still have the car), 2006 Z06 when I was still single in my 40's, numerous cars many would envy - and tons of projects including big and small block builds... and now a 2024 Z71 Tahoe with an L87 added to the fold, crossing my fingers. I'm embarrassed for GM.
Have a 23 Escalade, carfax sent me an email notice about a recall, but nothing from the dealer yet.
What are the "symptoms" of this problem?
My 6.2 has 7900 miles. Sounds fine, no ticking or other noises. Great idea to have dealer give results of inspection in writing--want to keep that on file.
I read a report it was bad metal and it has been corrected with updates. Toyota used the same metal on there bearings on the Tundra V6 that had failed too.
