Mine has 3 settings. "Near," "medium," and "far." When set to "far" i have the problem described in the origional post. It just follows way too closely. I don't even want to set it to a nearer setting, because the "far" is already too close.

2015 Yukon Denali. On my other vehicles the adaptive cruise control is a very nice feature, but on this truck it is terrible. Even at the farthest setting, it keeps creeping up on the car in front until it's dangerously close. I'm talking 10 to 20 feet away from the car in front, even at highway speeds. Also, it seems to accelerate above the set speed to keep up with the car in front. I'll be cruising along at 75, set at 75, and as soon as a car pulls in front of me it abruptly accelerates to 77 as soon as it recognizes the car. I find this very strange. In my previous car I loved adaptive cruise. In this one its unusable. Is this the same for anyone else? Or does anyone know how to fix this?

We know someone with a 2016 escalade and they got a letter saying that as a result of the class action lawsuit on the transmission, they could get it fixed for free if they are getting the P0711 engine code. We have a 2015 Yukon Denali, and we have experienced the common "jerk" in the transmission in this vehicle ever since we bought it and just recently got the engine light with the P0711 and P0700. We never received a letter, but since we know someone with the same car (mostly) who got the letter, I called the stealership to find out more details, and they said that our vin was not one of the ones "included in the class action". I called GMC customer service, they said the same thing. I was trying to ask them why this is, it has the same transmission model the class act is about, we experienced the problem that the class action is about, we have the engine code, I have no idea why this should not be included. The class action is clearly about the 8L90 and 8L45 transmissions. Its not just about certain vins. The lady at GMC couldn't give me a straight answer and just said it might have to do with the date it was assembled, or the plant it was assembled at, or where the parts came from, etc. I'm thinking more like they just picked out which vins they wanted to fix for whatever selfish reasons. Just looking to get a discussion going, to see what opinions or experiences people have to share...

Id certainly rather have bouncy over dips and bridges then feel like it's a covered wagon with wooden wheels and no suspension. Which was how our magneride felt before we deleted it.

I wonder what the premium ride consists of. Air suspension? It sure is hit or miss....

It may be better new, but it may not stay that way. Magnetic suspension went bad pretty quick on the previous generation of these cars, and after a few thousand miles they are worse then the regular ones. Not sure what has been improved in these new ones though. Air suspension might be the best bet. Not sure if air suspension still has a short lifespan magnetic system on it also.

We had a jeep ecodiesel catch fire due to failed egr cooler. I've also heard the duramax lbz is known to have some egr valve issues, such as it getting clogged by soot buildup or the valve failing, but I havnt heard much about fire issues on these engines. Does anyone know if its safe to ignore the engine code for awhile for an egr on the duramax? I'm not sure of the differences in egr systems between a 2014 chrysler ecodiesel and a 06 duramax. The issue on the ecodiesel was that the egr cooler cracked and leaked coolant, causing carbon buildup that was prone to fire when the exaust got too hot. not sure if this leaking cooler issue creates a bigger fire risk then the egr valve failure they talk about on the duramax? Just interested in hearing people's thoughts or experiences, if I have the code should I get it fixed asap or the truck will catch fire or is it ok to let it go for a little while? Thanks.

Just purchased a 2015 GMC Yukon Denali 4x4 (with the transfer case with neutral setting) and soon will be setting it up to flat tow behind a motorhome. Has anyone towed one of these or have any insight or things I should know. Any caveats? I am aware that the installation of the base plate is a little tricky, and requires some cutting, which is ok. My other question is when actually towing. I have heard some people saying on the forums about the electronic transfer case control having issues with not going into neutral or getting stuck in neutral. But these posts were back in 2015, so has this been corrected by now? Additionally, the manual says the battery must be disconnected, or else damage might be caused. I was going to ask if anyone has any experience to know is there a specific reason to disconnect the battery other than having the steering wheel unlocked. I have heard it could have to do with the electronic transfer case control coming out of neutral while towing, but does anyone have any experience that would back this up. Because it doesnt make sense why it would come out of neutral. There's a fuse for the electronic steering lock (it has the push button start) so I can remove that fuse to keep the steering wheel unlocked so I wouldn't need to disconnect the battery for that reason, but I am wondering what other reasons there might be for disconnecting the battery, just out of curiosity. Does anyone know exactly? Ideally I would like to be able to tow it without disconnecting the battery, so would be great to find out why it needs to be disconnected to see if there are any other loopholes. Any insights from those who tow this vehicle would be greatly appreciated. Thanks.
