So does my 5.1.
I think there is a difference which so far no one has pointed out. There are two groups of owners when it comes to issues of reliability: those who change their vans every few years before the warranty runs out, and those who have made a one time purchase and plan to keep their van for a long time. For the second group, electrical complications tend to be a disadvantage, because unless you are a specialist these kinds of faults can be much more difficult to diagnose and expensive to repair than mechanical ones. I had my Suzuki Bandit 400 motorcycle, one of the very first 16 valve motors, for 20 years, and when it met it's end motor and chassis were in perfect condition because I took care of it. But the ECU for the fuel injection gave up, and a replacement part was 1600 euros, which 10 years ago didn't make sense for a 20 year old motorcycle (now it would be a collector's item). I plan to keep my van, which is why I searched for a low milage 5.1. I'm not worried about mechanical failures, it's when I look at the cost of repairing the electronic systems that I cross my fingers and hope my luck is good.
