Let look at this way. You go to a nice Steak restaurant and one of their entrees is a NY Strip grilled with mushrooms and onions, baked potato, salad, and drink of your choice. Sounds good so you order it. What you get is the NY Strip grilled to perfection with mushrooms & onions and a good salad. Your baked potato came out a little late and was missing the butter, cheese, and sour cream and was prepared like it should have been. You drink was good too.
Now in that scenario I am sure you would have said something about the baked potato and would either want it removed from your order, redone, or part of your meal comped. Some people would look at the mess up with the baked potato a complete deal breaker and would refuse to pay for the meal or would want something removed because it did not arrive as advertised. Others would just say something and move on, and other may even gripe about it for the next 6 months to whoever will listen to them.
Why is the missing Off Road Pages that was advertised, all in the manual, and up until just the recently been communicated as being part of the JLUR with the 8.4" screen any different? On top of that this is affecting all the 2018 JLUR with 8.4" screens and not just a couple of people.
I will not return my JLUR over this and it would not prevent me from buying one. But that is my own choice and others can freely make their own choice over it as well. Another thing think about with this. What will they do about this for the customers that are affected by it? It makes it look like an unfinished product, a blemish. or a half baked gimmick with the 8.4" screen upgrade option.
