i believe the point i made in my post was that electronics were not made very well these days. I said nothing about the longivity of the life of engines. Of course i see engines running 12K hours and more, they have done wonders with oils etc to help engines run longer and for that i applaud the engineers on that aspect. But when 90% of your calls are for some failure due to a bad wiring harness or a failed electrical component like bad relays or broken shunts in a fuse box that shuts the truck down? These are just some of the most common issues i have dealt with and this is the largest complaint i hear from my customers.
Its just pitiful how much downtime they have to suffer at their expense because of a bad sensor or broken wire. Sure warranty may cover some of this sometimes but the customer still suffers the downtime and in some cases has to pay for a rental lift to cover thier out of service lift.

So on that point alone maybe you guys should backup and regroup before you start defending the issue.
How do you think a customer feels when he buys a fleet of trucks only to have the tech have to come out repeatedly for the same issues right after they buy the trucks, constantly repairing them while waiting for the manufacturer to come up with a permanent fix and in some cases not doing so?
