Just happened to us. 14xxx kms, just past the one year mark. Want to try to sell us on the rebuild. No thanks. But waiting for another 6.2 may take six months or more. Our 2012 with a 5.3 was at 359000 km when we sold it, nothing but a little oil consumption in 12 years. Sold it because I was worried about reliability. Ordered a 2022 Yukon Xl, waited almost a year to end up in a 2023 that they couldn't honor the price or financing. Everything about this has been a run around and now I don't even have it. Buyback isn't an option because now that truck is $20k more. I have been brand loyal most of my life, but this may change that.

Well, this one is a first for me.  First engine failure on a low mileage/warrantied daily.  Have blown up lots of hot rods and toys, nothing stock at 15k though.     Was on my way home from

Just wanted to post some updates.     Got the truck back first week of December.  Dealer rebuilt the engine.  Truck seems to run good, except for anything Onstar related.  The module apparen

I recommend you go over to the ram forums and read up on the 5.7 as they are having their fair share of engine issues from lifters to cams, manifolds etc. It's not just GM.

Welcome to the forum. This is terrible. What year and model truck do you have?

I work at a GMC Buick dealer and we are seeing these failures alot.All spun bearings on the 6.2 engines and no parts or engines available. Just had a 23 yukon towed in yesterday with 9300 miles on it. Locked up solid. Absolute nightmare,We are replacing another 6.2 that was ordered 8/22/23 and it just showed up tuesday! The lift next to that one is tied up with yet another collapsed lifter job.GM better get there ****** together soon.

I've been in the market for a new 1/2 ton, and the Silverado LT Trail boss was my top pick with the 6.2L.

 

After reading the horrors throughout Facebook and on here, no way in hell I'm buying one.  I've seen one person post they made it past 100k without lifter failures.  

 

I work in the auto industry and every GM dealer I talk to is making a killing on these trucks in the service lane from the warranty work paid for by GM.  

 

I wish they got their ****** together because now it looks like I'll be buying the Ram 5.7 before its gone, definitely don't want the Ford 5.0 because its the most boring vehicle on the road and the Tundra looks like its made out of legos with how much plastic is on it.

Have a 2021 Chevy TB with a 6.2. 

 

First engine failed at 22k in the shop for two months, Approx: 1 month to approve motor swap, 1 month to replace the motor. 

 

Second motor failed at 23k, took them one month to replace the motor.

 

Both failures occurred at cruising speed on the freeway towing a lighter boat.  Both bottom end failures.

 

I think GM needs to step up and do something about this, I talked with GM and they refused a buyback and/or full replacement.

I know a few guys with the previous gen trucks and a few of them have made it to 200k without a bad AFM lifter. Not sure what they're doing different to not have a problem. Maybe it's because they change their oil every 3 or 4,000 miles lol. 

 

All manufacturers are having issues. The new Tundra is having as many engine failures as the current 6.2 is it would seem. Lots of Tundras with destroyed main bearings at 20-30k miles. Toyota even has issues with the 3.5L they've been making in various revisions for the last decade. There's a big list of 2016+ Tacomas with 3.5L engine failures despite being well-maintained.

 

Ford is using junk rubber belts to spin the oil pump on the 2.7 and 5.0 these days and you have to pull everything including the timing chains off to change it. If you don't change it often enough, your engine will die. The youtube channel "I Do Cars" has torn down a few Ford engines with the belt and they all looked bad for the mileage and for how long Ford insists the belt is good for. Plenty of other issues that their engines have had lately... still can't figure out how to make dohc engines that don't have cam phaser rattle. 

 

Ram has always had issues with the 5.7 eating cams and lifters too but from what some people insist, the best way to limit your chances of that happening is to not let the 5.7 idle too long. I know a few guys with the current gen Ram that have been happy with them otherwise. 

 

Not deflecting from the issues with the 6.2. GM has obvious issues in their house when it comes to those engines. I have a co-worker that was telling me the other day that their relative bought a new 2023 with the 6.2 and it failed on the 2 hour drive home. Seems strange that so many manufacturers are having bearing failures like this.

I assume it's way too early to know whether they've fixed this for the 2024 models? I've heard it relates to some parts from Mexico during COVID so I'm wondering if it's been fixed by sourcing parts from elsewhere.

Still doing it.  Sure, its not every single 6.2 but its still happening.  Most of them are low mileage though, under 10k miles.  

 

It affected the 14-20 6.2s (L86) as well but not as prevalent/with more miles on them.  We have one we are waiting on an engine for that failed at ~80k miles.  We don't know when we will see an engine either due to the core shortage on L86s.

I’m not going past 2006 for a used GM. My 2014 was the best for ride, wind noise and performance. Especially with the E-85 option. I would love to buy a newer used GM. It’s just not going to happen. I don’t drive a truck enough for a new one. Talk about a crap shoot.

Was on my way home from hunting, coasting down from 75mph(spd limit) to 55 to go through a small speed trap town.  Heard some abnormal noises under the hood, was checking gauges/lights when the truck just died and shifted itself into neutral.  Luckily I was able to coast it into a feed store parking lot without getting ran over.  Dealer says its not in the valvetrain, something on the bottom end.  There's 4 other 6.2's in front of mine that they are tearing into the bottom end.  All have the same symptoms.  

 

Popular reading online is blaming the rod bearings on 22+ 6.2 vehicles, not isolated to Silverado/Sierra.  Hopefully GM is has already changed suppliers but who knows.  No timeline but its looking like I'll be driving the 2wd loaner for a while.

We bought our 2023 Cadillac Escalade in August 2022.  On April 13, 2024 we were driving on an Interstate at about 70 mph when the engine quit and shifted itself into neutral.  Luckily we were able to coast to the right shoulder and sat there for 4 hours until a tow truck arrived.  Diagnosis: Engine was blown with metal fragments in the oil pan.  It only had about 10,240 miles.   The engine was a 6.2L V8

I have a 2024 1500 RST 6.2L that the motor let go at 2500 miles… The dealership only said metal in the oil pan and they contacted GM and they authorized a brand new engine replacement. I do not want the same issues with the replacement engine that I had with mine… I asked how long and they told me a nationwide backorder for the 6.2L and NO ETA on a replacement engine. I heard there is a main journal machining tolerance issue on the Sialo Mexico built motors and GM is moving the machining back to US…any truth to this?

I have not heard this. You are the first one I have heard this from.

      Higher oil pressure after DFM shut off

      Thanks!  I figured as such; GM and other manufacturers have used standard parts and harnesses across trim levels and such for decades.  I pulled the blank accessory cover off of my commuter van (a 2016 or so Chevy 15-passenger) years ago and found the plug for a USB outlet.  It wasn't connected to anything, though (I tried swapping in an outlet from another van).  I was a GM Tech years ago (late-90s) and was pretty familiar with my 2006.  I might be wrong, but I view newer vehicles (pretty much anything made in the past 20 years) as being a lot more plug and play.  Meaning, more unused wires and plugs unless you have the Mack Daddy of vehicles.

      not all plugs will be used.  gm uses more generic harnesses that support most/all options, and if your truck doesn't have a specfiic option, the plug won't be used (commonly will have a dummy insert in the plug , or it'll be taped up, but some may just be left as is).  But it's sldo possible some p.o. has installed the wrong/cheaper parts that aren't correct for your vehicle...

      First off, I'm not trying to just get easy advice/fixes for the issues I've noticed so far.  I'll be combing through the site via searches and such, and if past experiences are any indication, should find what I need.  For the sake of conversation, though, I figured I'd post the handful of things I've noticed in the 12 hours since buying my 2010 SLE CCSB.     Indicator lights: Airbag and TPMS.  The tire pressures aren't reading for any of the wheels, so I'm pretty certain the sensors were either removed, are damaged, or are otherwise inoperable.  I used to mount and balance tires 25 years ago but am pretty much ignorant when it comes to TPMS.  My 2006 didn't have the sensors and this might be the fourth vehicle I've owned that does.     Radio: Rear speakers aren't working.  I removed the driver's side rear door panel and checked the speaker and wiring.  I also removed the sill and b-pillar covers to check the wiring.  A few minutes of Google Fu showed that this is potentially a head unit issue.    Switches: Power mirrors don't turn left/right.  I ordered replacement driver's door switches that should arrive tomorrow.  The windows and locks work but it was only about $20 for all of them.  The driver's side rear window switch lets the window down but won't put it back up.  I think the passenger rear doesn't work at all.  In the coming days/weeks, I'll break out my multimeter to check all of that.   Unknown wiring harness: There's a box attached to the front driver's side of the engine compartment, right where the second battery shelf is located.  There are three plugs, one of which looks like it fits a standard headlight-style bulb (9007 or similar).  It doesn't look like it's plugged into anything.  I'll do some digging and if I don't see anything elsewhere on the site, post some pictures here.   Unknown plugs on brake booster: There are at least two female plugs on the brake booster that aren't being used.  I think it might be a replacement/aftermarket, so maybe those are used for a different application, as there don't seem to be any unplugged harnesses and no indicator lights are on.   Little squeaks when turning: Sounds almost like a bushing around the bed of the truck.  I'll have to pay close attention as I get more familiar with the truck.   Clunk on acceleration: possibly the infamous drivetrain clunk.  My 2006 had it and I'm just not familiar enough with this truck yet to fully grasp what it is.   Anyway, my apologies for the vague and all over the place post.  This truck is new to me, and it's been four years since I drove my 2006.  With 200k miles, I know I'll need to learn this truck quickly to avoid having any major issues, despite being confident it's got much more life to it.  My 2006 had nearly 320k on it when I parked it (nearly 300k of which I put on the truck), and it was still drivable then, though I suspected the head gasket might have blown.  I'd hoped to have that truck back by now, but it's gone forever, as I detailed in my reintroduction thread.
