My friend and I were talking, that it could maybe be an antenna ground problem with the new aluminum bodies. Same issue we will have with our Ham radio antennas. The sirius signal is low power so the ground is critical.
Interesting...that's actually a possibility. Anyone have ideas where to start testing for the ground? I don't know where the Sirius connection/ground is other than behind the NAV unit in the dash.
Or maybe the antenna itself on the mount in the roof. My sirius is working fine, I am getting data and traffic, so far. With my Ham antennas I will probably have to run a ground strap down to the steel frame for a decent ground.
I took mine to a dealer today. The traffic does not work and they showed me a service advisement from 10/26/16 that says it doesn't work on some 2016-2017 vehicles and there's no fix at this time. I'm not sure why it works for some people.
I haven't been in any of these areas yet with it. I will drive it to work (DC area, about 200 miles away) one of these days and take pictures and will test it there. I'll post back when I do.
Wife and I took the truck to the Baltimore area with a stop at the new outlet malls in Clarksburg, MD on the way for a Christmas party and I noticed when I got on I-70 from I-68 the traffic started working on the nav. Pics attached are taken throughout the trip.

I don't understand your concern. Aluminum is a FAR better conductor of electricity than steel. I could understand dislike metals coming into contact with each other - after quite a long time, but other than that, I don't understand your issue with the grounding strap.

Yes, aluminum is many times a better conductor than steel. Even on a steel truck its best if all of the panels are bonded together and to the frame especially if running HF.

Being a good conductor does not necessarily make it a good ground. Steel is denser (right?) and that's why frames are often used for grounds. If you recall Ford addressed corrosion concerns by using adhesive where steel and aluminum meet, so there is no conductivity to the frame unless the glue conducts and that's unlikely.

This is why I suggested that the frame and body be bonded together. I use the shielding out of coax for my straps. I crimp and solder a ring connector on each end and then use existing screws or if necessary self tapping screws. You would have to use stainless steel screws for the aluminum.
As far as the best ground goes an antenna requires a ground plane. This is the largest piece of flat conductive material that you can find. This is why the roof is so popular, that and the fact that the center of the roof gives you a true omni pattern.

Also just to point out this is happening across all markets Chevrolet Toyota Honda all that have Sirius XM Traffic.
The information below is the service bulletin that I got from Ford.
SSM 46151 - 2016-2017 Ford And Lincoln Vehicles Equipped With SYNC 3 And Navigation – SiriusXM Traffic Not Loading
Some 2016-2017 Ford and Lincoln vehicles equipped with SYNC 3 and navigation may exhibit a condition in which the SiriusXM Traffic Listing is not loading but all remaining Travel Link features operate properly. SiriusXM Traffic is only available on vehicles equipped with navigation, only in select markets and requires an active subscription to SiriusXM Traffic information. If SiriusXM Traffic will not load attempt the following procedure. Turn the ignition off, open and close the driver’s door, wait for 3 minutes, then drive the vehicle outside to obtain a clear view of the sky. SiriusXM Traffic should recover. If SiriusXM Traffic does not recover continue to monitor OASIS for future updates.
Engineering is aware of this concern and no component replacement or any software re-flashes should be performed at this time. The SYNC version can be confirmed via OASIS.

I'm not sure you'd want to put stainless steel screws in aluminum. That sounds like a recipe for disaster to me.
I bolted a piece of 3/16" steel on the frame of a 99 trans am that stuck out the back over one of the exhaust tips and bolted a metal pole to it with a screw head. I then screwed a coil onto that (mid-mount coil) and then put a whip on top of that. I had coils for 80, 40, and 20 meters. I used a coupler for 10 and 6 to just have the whip on the coil. I used to drive around on 75 meters. I had a ICOM ah-4 directly driven against ground in the truck and it worked very, very well. I used to get good reports out of Canada on 75 meters from California.

I am not sure what kind of screw you could use if it wasn't stainless. I put some aluminum tread plate under the fender wells of my RV and used SS screws. I also oversized the holes and put black silicon RTV under the screw head. I guess some large aluminum rivets would be a good choice for the ground straps.
