I believe they need to re-think their approach to meeting the epa emisions.  (Get rid of the exhaust filter and EGR)  Keep it as simple as possible, with the least heat, even if it requires keeping another fluid on the farm.

Water pumps, I can't stress this enough.  We have newer equipment in which almost all machines water pumps have failed and almost ruined the engines.  Put a shaft that is separate (out in the open) from the crank case and doesn't rely on seals to separate fluids and bearings if they think that is so much more efficient.  Do not risk the life of the engine just because of a water pump!  800 hrs is way too soon for any water pump to go out, and the preventative maintenance is expensive to say the least and stupid when there are other brands that simply don't have new engine failures do to a water pump failure.

Electronics, if you're going to put that junk on there make it reliable.  As others have said you fit the bill for five years.  I'll bet the quality on everything will increase.

At the current prices of these machines, there should not be any break downs on new machinery and they should be hands down more reliable all around than the competition.  I can honestly say that I'm afraid to trade to newer equipment due to the increase in electronic garbage that is already malfunctioning and emisions and I'm only 29, so new paint should be a thrill to me....
