Instrument Cluster and Climate Control issues

John Balways · November 22, 2018

1) The instrument cluster between the tach and speedo resets along with the HUD. This happens quite often, I have owned the truck for a month now and it has done it about 50 times. I did find a service bulletin: #18-NA-324.

2) The movable air control door hidden inside the dash seems like it 'sticks' and won't position itself properly for what is asked from either the touchscreen or manual controls. For instance, when I remote start the defroster is automatically set. That works fine; but in order to get ANY flow to the floor one must first select the combo defrost/middle area to 'unstick' the door. You can literally hear the door unstick and move. You can then select to the floor for air flow and it will work.

3) On a smaller note, the right rear door does close properly; it seems like it rubs on something during the closure process; I'm sure that is just a simple adjustment that I will get done at the dealer during my first service.

1. I'm going for update on Friday, seems like everyone that has had update says it fixes issue.

2. & 3. I'd take to dealer.

No need to go to Dealer for the Update, just download it in your truck.

Thats the Radio Update which doesn't fix the hud/dic issue. The programming and possible dic replacement needs to be done by the dealer

So then you have a very early built truck that requires a replacement?

I am after the date that requires replament but programming is still a dealer issue. Radio Update does not fix.

Hi, John. If you need an extra layer of support while working with your servicing dealership, we're only a private message away.

Update: 4,500 miles on truck now and we have a new problem: check engine light was on all day yesterday, on a Sunday, otherwise I would have taken it to the dealer immediately. Now Monday morning and no check engine light so I will continue driving it until my first scheduled maintenance (7.000 miles), or the check engine light does not reset, whichever comes first!
