Had one of the first 2014 Acura MDXs - actually the first to leave my dealer's lot. It was a mistake. Numerous issues and many simply could not be fixed. So many changes and new things introduced that I had not anticipated. Many were software, others were not. And the techs at the dealership most often stumped. They new me by name and their standard answer was, "here is the number for corporate customer support". Now that said, the mid-year 2014 models had already addressed a couple of things. Other fixes didn't show up until just recently. There are a lot of them on the road now and I expect people love them for their intended use. But I would never have been able to bring that 2014 up to the level of fit and finish and robustness that the 2016s have. As it was, I realized I would need an off road vehicle and did not want to use the MDX for that - so I am a very happy LR4 owner. But I learned a lesson about gambling on the first year or even 2 of a new model.
I'm expecting that when it comes time to replace my LR4 I'm going to need to fall back to a Land Cruiser. Since the recent LC has a number of changes including an 8-speed transmission I am counting on my LR4 to last long enough for that release of the LC to prove itself out. So maybe a 2018 model.
BTW, I doubt I'll be considering the Discovery (or whatever they call it) as I am expecting a reduction in towing capacity/stability and if anything I would need an increase. So the LC is likely to be my best option for a luxury, offroad-adequate, travel-trailer towing SUV even though I hate their lack of ingenuity and attention to the interior cargo space and seating. And I'll miss a number of awesome features on the LR4. I hope I'll be surprised by the Discovery. I hope it will have big windows like the LR4 and LC. I hope it will have a usable split tailgate. I hope it will have solid, stable towing capacity with weigh distribution hitches that exceeds 7500 lbs. I presume that it will have 4L and all the off road goodies the LR4 and LC have. I hope it will retain the amazingly configurable and sizeable cargo space. I hope... but for know I'll just continue to love my LR4 which should not hit 120K before 2019. ;-)
