    2021 RWD Denali Differential Service recommendations...

    Yeah, did that and double and triple checked -- doesn't mention a thing about differential. Have you read the manual?

    Is there a recommended service interval on the differential?

    Premature tire wear

    I actually switched to the Pirelli's at 2,000 miles. I was able to sell the factory tires for a little more than what discount offered me. I have put 19,700 miles on those Pirelli's and they're already down to 5/32. I am going to put the Defenders on in a couple months.

    Driving in L9 and DFM

    Looks like they'll never be a Range or Pulsar LT device for our rigs. Bummer.

    Test drove the new Escalade today...

    Ask the dealer some direct questions about lifter failures in those motors and what GM has done to fix the issues.

    Yukon Denali stranded me today ...

    Got it back today. They replaced the lifters on that side of the engine, couldn't get approval to replace the other side. They are working on extending the warranty. Really great dealership, I am just so annoyed with GM and their suppliers. GM needs to do a recall and replace all lifters...

    I believe there is a TSB, but no recall.

    2021 Yukon Denali---POS

    You need to read the link I sent and do some more learning. I am not going to argue this. DFM is not new to the 2021 model year, it was first introduced to the pickups in 2019, and then the SUV's in 2020. The lifter issues were supposedly determined to be in the July 2020 - October 2020 window.

    Concerns with new generation Yukon

    I haven't asked. Good question for when I talk to them tomorrow. I do have a theory, however.

    Concerns with new generation Yukon

    The service director has ordered the complete set of lifters, and he's working on approval to replace them all. If he isn't able to get that approval, then I intend to escalate the issue.

    Concerns with new generation Yukon

    Update to this post -- had lifter failure at 5,070 miles while headed out on vacation.

    Yes and yes. My guess is they found a new supplier for lifters for cost savings.

    Nasty looking oil after 5200 miles of driving

    I just got my oil changed at 722 miles. Then I got the 5000 mile oil change at 4870 miles before we went on this trip where our lifters failed. I checked the oil before the oil change, and it looked clean like honey on the dip stick. Mobil 1 extended performance with regular wix filter...
