As I said, it would not be an engineering decision. More likely it was to make it easier to upsell from the Laredo to the Laredo X.
Keep in mind there was a directive to lower the base price of the 2012 WK2 by 10% and the easiest/cheapest way was simply a program change to remove some features.
This is my first Jeep but I have been tinkering with cars and reprogramming them for a long time. Being a GMI grad, I stuck with GM until their cars diverged too much from the three Fs. Have a lot of 3800 parts anyway & understand them.
However, my son drives the TranSport & I needed something to replace it for trips and towing. Was looking at 3600 lb 2.5 liter things (Terrain, CX-7&9) since there are no suitable turbo-diesels available in this country but frankly they all seemed tinny. GF put me onto the GC and despite (or perhaps because of) the 4400 lb weight seems really solid.
Have only driven it about 120 miles now but is getting better mpg (18.6 in town) than the reprogrammed Reattae which was quite a surprise (had seen dismal reports about the Enclave/Denali which are a similar size). To me, Pontiac is gone and Buicks look oriental. May sound strange from an engineer but I like the GC steering wheel better than anything from GM.
Getting far afield (is there a newbie intro thread ?) my feeling is that the Laredo was deliberately "decontented" to meet a price point (always felt GM devisions had an "ugly" stylist for low lines) but that Chrysler kind of missed the mark since I have always liked clean lines, minimal chrome, and the very dark plastic hides the imitation woodgrain. Have a few changes planned (Katzskins, side step rails, sill plates, bed liner) but frequent passenger likes the chrome grille so the SRT option is out.
Meanwhile back at the thread, it does seem surprising that part of the overall decontenting would be a safety related item such as the tire pressure readout. IMNSHO.
