Bought the AWD because we were moving out to the country. It was a company lease return, impeccably maintained. As soon as the warranty expired, we IMMEDIATELY suffered the infamous GMC intake manifold gasket debaucle. Since then, nothing but problems, mostly with the wheel hubs, bearings, and ABS/AWD sensors. Turns out a vehicle named "MONTANA" with AWD can't handle a bumpy gravel road. Worst vehicle we've ever owned... period.
Size. AWD, when it's working.
Eliminate the obvious design flaws, from the IM Gasket to the AWD system that craps out after a few bumps. Don't tuck every fluid reservoir away so you have to be Reid Richards of the Fantastic Four to fill them. Scrap the cheapo-plastic approach. And then let the Japanese build it!
