I just finished 2300 miles from NM to Northern California and back. 22.5 mpg average speed of 74. I was running about 1900 rpm most of the time. 91 octane gas. 2017 Yukon XL with 6.2L 40K miles after trip.
Safety, yes, this is one of the reasons I drive my Yukon XL. 95% of my driving is on the highway and the last few times that there was a close call it was with a Prius driver. Glad to know that you are ok and that she saved you from a far worse fate. A little bit of buffing should take that...
I just did 2200 miles NM to NoCal and back with 21.7 MPG and 65 average speed. My best was between Gallup and ABQ with 25,6 MPG and 72 average. Love the ride and power. 2017 Yukon XL. I seem to get better mileage with cruise control set to 80.
GM wants $99.99 for an upgrade to the navigation system. The Garmin system I have had for a while comes with lifetime upgrades. Is the GM upgrade worth the money? How difficult is it to do yourself?
I did that and it works just fine. Doing that changes the shift points to a higher RPM, which is OK. I wonder if it has any other side effects like lower gas mileage.
I don't know why GMC doesn't have LED lights all around this vehicle.
I installed LEDs for my back-up lights and for the license plate lights. Really made a big difference.
The first picture shows the back-up lights. The original is on the left and the LED is on the right. The second picture...
Hi, I have a 2017 Yukon XL. The turn signals flash 3 times when you just tap them. I like this and would like to make them flash 5 or 6 times instead of 3. Is there a way to reprogram this without getting a chip programmer like a Bully Dog or others?
I have a 2017 GMC Yukon Denali XL, 6.2L engine. I put the K&N cold air intake on my 2008 GMC Sierra and noticed a big difference and love it, both gas mileage and power. My question is with the larger intake on the Yukon XL will the K&N system really make any difference?
I have a 2017 Yukon XL with the 6.2 L engine. The manual says that premium fuel is recommended. Will running regular unleaded instead of premium unleaded really make that much of a difference in either the performance and/or fuel economy?
I know that this may not be the right site to asak about a 2008 GMC Sierra but I was wondering is there a similiar site for this vehicle?
My specific question is "Does anyone know how to change the door mounted speakers?"
Does anyone else believe that the Denali mirrors should have the convex section on them to see the blind spots? This is a high end vehicle with huge blind spots. Yeah, the little yellow light comes on but I want to see where the vehicle is that is next to me.
I would like to change the right and left side gray-tone trim pieces on my steering wheel to the matching wood trim pieces like the rest of the interior. The pieces are called "covers" but can't find where to get them. Any ideas?
I have been trying for a while to get this to work and after much research have found out the reason that it never worked. The manual says that the sensor is in the middle, top of the windshield so I assummed that it was in that black triangle. NO. the sensor is actually in the mirror. If you...
2017 GMC Yukon XL Denali Does anyone have an experience with the wireless charging? I have an Otterbox cover on my Galaxy S6. Do I have to remove the cover to get my phone to charge?
