I have had a Hyundai iload 2.5Diesel for 4 years from new with no problems at all. But there shouldn't be really should there?
how meny miles is on ur van now i was looking at these a wile back but ended up geting a vivaro thats bin ok new gear box and a set of pads so far just hit 50k today 
Only 21,000. I virtually only use it for work and my round is getting more compact.
It was about £16K in March 2012 but there was a small 3% "business subsidy" (£480) reduction because I bought it at a local dealer and it was sold in my business name not just as a self employed individual.
It has a 5 yr 100,000 warranty so I have a year left. (Not wear and tear items after less time like discs and pads or clutch or aircon recharge 3 years.)
It has just had a set of front pads at 20,500 miles and the backs are reportedly half worn from new. I am on my second set of tyres. Strangely for a rear wheel drive the fronts wear out first. Probably all the 3 point turns I do.
I suspect the clutch will be the first major item to wear out, but no sign yet.
Mpg was about 25 when it was two up plus 650L water at the start of every day, now it is about 30. But I only do about 425 miles a month and carry 400L at the start of the day, down from about 500 miles when I was two up.
I think the back door hinge "stops" are a bit worn as a strong wind will close them but that might just be my imagination. They get a lot of use of course.
You can get a lift up door now which I would consider but couldn't when I got mine.
