Yes. I live in Central Illinois and my dealer had 2 2018's with the eAssist when I bought mine.

There is a factory spec for a reason. Find a shop that wants to make your truck right, not just close to right.

For what you'll pay for them, you could easily find a local shop to swap the springs to the Bilstein's for you, probably for less.

Which nut on the leaf spring? I have a slight shake at 70-80 and am willing to try anything. Dealer has stated they're willing to chase this issue with me even to the point of replacement, but I refuse to go through that just to get another truck that shakes. I'd rather take a little time trying whatever it takes to make this truck right.

See if the stereo you installed has a parking brake wire. Sometimes, you can defeat those systems if you can make the stereo think the parking brake is set (car is parked). The signal that wire needs varies, so you'd need to see if it needed to be grounded, or see 12V+ to 'activate' it.

Having anything plugged into the OBD-II port keeps On-Star from being able to generate the monthly reports they send for you. That was the only downside I saw when running my Automatic adapter in my 2014

I also think it's offered through On-Star as a "sweetener" to lure people into paying for the astronomically high 4G data plans they offer.

You need iOS 12 and also need to update the Google Maps and Waze apps for them to show up.

...and fuel filter.

I have no experience with Fox shocks, can't comment on them. I personally can recommend the BIlstein 5100's. I put them on my 2014 and it radically changed the ride. I plan on installing them on my 2018 when the stock Rancho's shoot craps.

You have to update the apps themselves to get them to show up in CarPlay. Also, don't get *too* excited about Waze on CarPlay just yet, it has been locking up and crashing on me quite a bit.

I just remembered. Recently I've been having to unlock my phone after plugging it in since the update to iOS 12. For whatever reason, it forgets the "use carplay while locked" setting and requires me to unlock my phone to get projection to show CarPlay.

If it's under warranty, take it to the dealer. Sounds like HMI issues.

This is why I stopped going to one of the dealerships where I live. Took it in for one of the free services, came out and saw the brake dust on the front rims. Asked why they didn't rotate the tires. Was given a line about the tread depth and GM not recommending them being rotated until a certain disparity in tread depth was reached. I informed him that GM no longer owned my truck and I wanted the tires rotated. He refused. Left that place, never went back and I bad mouth them every chance I get.

Make sure you are using an apple cord or one that is apple certified. Even with an apple certified cord I sometimes have to unplug/re-plug to get the system to recognize the phone (iPhone X on iOS12)
