Just came across this thread. I had a similar occurrence with my 3.0l Duramax at just around 5,000 miles. Engine shut off coasted to a stop with zero drama. Thought it might be the battery and tried a jumper box. Ended up being a siezed engine. It was about 5 weeks to get it replaced. I now have...
And, tows better. And, less expensive to buy. And, less expensive to drive versus 6.2l. I've added 2 jugs of def in 12,000 miles @ $17 per jug. I filled up with diesel yesterday $4.52/gal. Premium (what is spec'd for the 6.2l) at the same station was $4.87/gal.
Diesel again for me. Diesel and premium are close in price. My 6.2l (premium gas) was lucky to get 21 mpg on the highway. Diesel always is 30 mpg or better on the highway.
Mine gets whatever the dealership uses. I don't give it a second thought. One, I'm not going to keep whatever I own much past the OEM warranty period. And two, I don't do my own oil changes anymore. DIY oil changes stopped giving me warm fuzzies a long time ago.
I had air suspension on my 2019 Ram Limited pickup and was really happy with it. It had an entry feature that would lower the truck and make it easier for my mil to get in. Does the Yukon system do the same?
Mine wasn't a thrust bearing. No weird noises. Just locked up. Didn't know that when it happened. It was like I turned off the ignition and costed to a stop. GM didn't have the dealer open it up. Just crated it and shipped it back. No warning lights or anything. Acted like the battery died.
Really not brave. I looked at it as being no different than if your a/c compressor craps out. You get the defective replaced and continue on. My neighbor has had the 3.0l for a couple of years and his brother has put over 100,000 miles on them. I just had a fluke. The new one has had no issues...
I have the LZO in my 2025 GMC 1500 Sierra Denali and I had the engine sieze while driving with about 5,000 miles on it. There were no warnings, no drama. I started to accelerate away from a roundabout and it "shut off". The dash said to place in park and restart. We'll, it didn't. Engine was...
I plan on using this forum more as I get closer to ordering. I told the sales manager I want to be the first in the queue. Just need to determine what options will carry over and colors.
