No worries it’s hard to capture the photo with little space. The photo is as if you were laying under the dash, under the steering wheel area, looking up into the dash from around where the pedals are. So if you kinda lay in that area looking up at the dash area (it’s a pain to fit in there) you should be able to find that hard drive looking thing. It’s got a wiring harness coming out the back, Tap it with your finger a few times and see if it makes a noise.

Replying to this because I just recently solved a rattle that was driving me crazy. My rattling sound sounded like it was coming from the left part of the dash behind the headlight/4wd selector between that and the upper left tweeter cover, but this was just the way the sound bounced off things into my ear. It sounded like springing plastic (sorry weird comparison) but it actually came down to a module that looks like a hard drive behind that dash that is around the steering wheel column. You can can get to this without pulling off panels, but removing the under steering wheel panel helps; which is two screws and some pressure clips. When searching for the sound, I tapped on this module and it made a metal vibration sound, it didn’t sound like my rattle when sitting in the seat driving, but I believe it actually was, must have been the way it was muffled and traveled that changed the tone. This module has a wiring hardness coming out towards the front of the truck, it has a small heat sink on it. I resolved the sound by placing a piece a piece of rubber between the module and a metal bracket, it stopped the metal module bracket from being sprung. I attached a picture of the module circled in yellow and the fix I applied. This photo is looking up the dash from the floor. Hope this helps someone if they are searching for an annoying rattle while driving. Just one of the many this truck has.

I seem to remember an old thread on here, I think it was that you have to manually start it every nth time (not sure what number n equals). As in, you can't remote app start it a bunch of times in a row without a few manual ignition cycles. Was some software limitation they implemented. This might be different, as I thought the key fob counted as a manual start, but something to consider.

Definitely keep it, prefer it over any other method at the moment.

I was having vibrations in the same manner as many here noted. They were at around 38+mph and again around 72+mph, it seemed like they didn't always occur, but did much of the time. I did not believe it was the tires due to my own experiences in the past and after reading parts of this enormous thread. The vibrations were not strong, but the stiff suspension makes the vibration reverberate though the chassis and made it felt through the seat. 1. I had the dealer do a balanced few weeks ago, but this caused a strong distinguishable recurring bump vibration while driving at those aformentioned speeds. 2. I went back and they attempted a rebalance on a tire that was giving the machine trouble, this changed the behavior of the vibration, it made it recurring small bunches of vibrations. 3. Went back again and they checked it again and replaced the tire and I think it finally solved my issues. So I just want to share this info, because at first I didn't think it was the tires, but after consistency, they happily changed my tire out. The dealer never gave me any trouble and was always friendly. If your vibration is not strong, but clearly distinguishable, and you have possibly had a balance: do another balance or find a better shop to do it with road force, you may just have a bad tire as I did. I hope my issue remains fixed at this point, as I am hypersensitive to the vibrations/noises my vehicle makes.

Mine does it as well, my last 2010 6.2 did as well. Not sure if there would be fix for it, I think it is because the cat/exhaust is so close to the floor. In my case I know it isn't the flapper as the 2010 had the same sound and did feature a flap valve. I was debating on heat wrapping the exhaust around the driver door area, but have yet to try it.

I took mine to the dealer previously, they couldn't reproduce it, as it only happens occasionally on my truck.

I noticed this, it drives me nuts, I haven't fully solved the noise that is often associated with certain temperatures for me. I did put a shim to reduce flex, but I still sometimes get the creaking noise.

I found that on my adjustable petals there was also flex in the large plastic bracket the pedal assembly sits in. It was making a terrible plastic torsion sound at certain temperatures. I used some left over EPDM rubber roofing material on the side of the bracket, literally just folding it and stuffing it in, and it seems to stiffen it up quite a bit. I am hoping the sound/torsion is mostly gone. The small things....
