HELP! 6.2 engine seized up @ 108,000 miles

Pickichvino · November 14, 2024

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.
