How about some gas mileage reports?
2021 GMC Yukon Denali Diesel with 4WD. I'm currently averaging 25mpg on the first 1350 miles. I recently averaged 32mpg on a relatively flat 100 mile highway trip with the cruise set at 72 mph. Significant mpg improvement over my previous 2001, 2007 and 2015. Also nice to be able to go 650+...- brkoom

Ordering Delays...What would you do?
I'm in the same boat with a '21 Denali Diesel order. It has been pending pickup from GM for over three weeks. If you need it before March, you probably should look at the current inventory.- brkoom

Rear Power Door Lock Stopped Working
Hi Everyone! I have a 2015 Tahoe. Over the past few months I noticed that the rear drivers side door didn't always unlock when I put in park. Now it does not lock or unlock with the other doors. Is this a Door Lock Actuator issue? If so, it this is a difficult DIY repair?
