Single owner of 2019 Chevy Silverado 1500 LTZ with 6.2, experienced “low oil pressure” alarm while driving home and pulled over immediately and shut off vehicle. I had the vehicle towed to the dealer and they said the engine was seized and want to replace the GM long block, quoted at $9,500 for the job to include labor. I began to notice what I perceive to be as lifter noise a week prior, nothing overt but I had to listen very closely to make it out. 
 

When I followed up with the dealer the guy said that they need to tear the engine down to be sure but they are thinking that maybe there was a “crank failure”. I’d say it would be hard to diagnose anything without having access to the rotating assembly but wanted to see thoughts on here.
 

Mainly, I’m 8,000 outside of the 100,000 manufacturer powertrain warranty and I feel like I’m going to get hosed on this from big GM. I’m going to start working up the chain with my complaint but have a feeling this will go nowhere. Anyone have any insight to this engine situation or any recommendations on how to best proceed to get GM to provide compensation?

You are 48,000mi outside of GM factory warranty and likely out by time as well.  Powertrain is 5yr or 60k miles, whichever comes first.  

 

Sorry to say but its likely to be on your dime.  The dealer can try the customer assistance calculator but you better have every record of any oil changes or repairs made to the engine, and if they cover any, it will be well under 50%.

 

High probability the main bearings are toast, possible rod or two as well.

If you heard lifter noise (tapping) a week ago you should have stopped to investigate it then.  It was in the middle of grenading itself and you kept on driving it.  What happened more than likely based on your description was that one of the DFM lifters started to fail (known GM issue) and started to gall. It quickly spread the contamination through your engine and ruined the bearing surfaces.  Pull the oil filter and cut it open.  I bet if you remove and spread out the element it will look like you found gold on the Yukon river.

GM has reached out to you. Follow up with them. That is your only chance for any help. Most likely the engine replacement will be on you. I would also replace the oil cooler as it will be loaded with contamination.

100,000 mile powertrain is currently offered on 3.0 and 6.6 duramax's and on the 2.7 turbo 4 cyl., but not on the 5.3 or 6.2

I will reply to GM customer service shortly.
 

I was quoted that I would get a 100,000 mile warranty on the replacement block so I wrongly assumed I had the 100,000 mile powertrain warranty originally. Sucks to be me.
 

I will be putting the replacement 6.2 long block in but don’t have an ETA from the parts department on when it will be in. I’ve heard there is a back order on the item. I’ve read where the dealership replaces the lifters with the same defective manufacturer as a replacement.
 

Is there any other option to not have the lifter problem again? Any other items that are recommended to be replaced? I was hoping to get 250-300,000 miles out of this truck before I replaced it, I’d like to do what I can to squeeze more life out of my truck.

If you're going to be installing it, go ahead and delete all the DFM stuff out of it before you install it.  Will be 100x easier on a stand than doing it in the truck.

    • My 2025 Silverado 1500 had to receive a brand-new engine (long block) under warranty last month at only around 16,500 miles. Before the replacement, the truck repeatedly displayed "Engine Oil Level Low" warnings, even though the Oil Life Monitor still showed around 50% remaining after about 6,000 miles since my last oil change. After seeing the warning several times, I checked the dipstick with the engine cold, and the oil level was completely normal. The next day, the message escalated to "Add Engine Oil." At first, I assumed it was just a faulty oil level sensor, so I brought the truck to the dealership. After inspecting the engine, they found internal cylinder wall scoring and ultimately replaced the entire long block under warranty. Before this happened, I was planning to install a 4-inch lift and suspension upgrade on my truck. After needing a new engine at just 16,500 miles, I honestly don't see the point anymore. I also contacted GM to ask whether my vehicle qualified for a buyback, but I was informed that it does not at this time. Anyway, this experience has left me with serious concerns about the long-term reliability of this engine. I sincerely hope NHTSA expands the current investigation or recall to include 2025 model and performs a thorough inspection of affected vehicles. My biggest concern is that these engines may fail shortly after the powertrain warranty expires. If GM truly stands behind this engine, then at the very least, please consider extending the powertrain warranty to 10 years for affected owners. That would go a long way toward restoring customer confidence.
    • Without exception but then I'm the odd duck, right? I know what goes into that test, how it is calculated and thus how to beat it. But EPA values are often not beaten by the general public and the government has in past years adjusted the means and methods to come to those values to more closely approximate "Joe Average".    The only real trick to beating that EPA average is don't drive like "Joe Average".    It's the same method you used to profit from "Economic Migration" and in doing so beat the 'stats'. But you, like me, are not "Joe Average".     The thing you don't seem to grasp is this "Purchasing Power Index" isn't forward looking. It doesn't predict what it going to be but looks backward and states what it was. They are not telling us what the THINK, they are telling us what they MEASURED. Example:    Wife says "I'm going to lose 40 pounds by Christmas". May she does, maybe she doesn't but the doctors office who weighed her when she made that statement and again at Christmas only REPORTS what the RESULT was. You and I can banter about what was possible and what aunt Tilly did till the cows come home but the result is the result. Arguing otherwise is.....irrational. That's all I'm saying. This isn't about:      What you are calling a 'Statistic' is a RESULT not a CALCUATION and as a result the RULE. Like gravity as a rule, it can not be broken. 
    • Just wanted to say thank you for posting this. Years later, your thread is still helping Silverado owners.   I bought my 2025 Silverado 1500 in January 2025, and I've had what feels like the exact same rattle since day one. After reading your findings, I believe my truck has the same issue with the cable carrier contacting the rear sliding window. To be honest, I had pretty much given up on pursuing the issue. It wasn't until I recently drove another brand's pickup that I realized just how quiet their cabin was—and how noisy mine has been all along. On my truck, the rattle happens on almost any paved road, gets even worse on rougher pavement, and I can even hear it during braking and acceleration.   I actually referenced your thread when submitting my case to GM, hoping they'll recognize this as a recurring issue instead of treating it as an isolated incident. The reason I reached out to GM first is because my dealership told me they would need to keep the truck for at least two days just to diagnose the problem. I was concerned that even after two days, they still might not be able to identify the source of the rattle before giving the truck back to me. I had also asked a few dealerships about this issue during previous service visits, but none of them seemed to know what was causing it or had a solution. That's why I decided to contact GM directly first, hoping they might already have an official repair procedure or guidance for this issue.   I also hope GM eventually comes up with an official fix for this problem. I have a feeling there are many Silverado owners experiencing the same rattle, but most either choose to live with it or simply don't know what the cause is.   Really appreciate you taking the time to document your diagnosis. Your post is still making a difference years later.
    • I have 2 choices. 
    • Do you have access to BP fuels? Some stations have Silver 91 E-0 priced the same as their 93 E-10.  There is a local Marathon with 90 alky free for $6 a gallon but I go down the road to BP for $5-ish. They also have a 100 E-0 but that stuff is $10 a pop.
