As a non-sequitur, bugs don't show up much on a Volt's windshield either. While I suspect it was done to reduce wind noise over the wiper blades when they're parked, a side effect of the scooped hood is it forms an aerodynamic "ski jump" for bugs.So far the Volt has been fairly problem free but bugs don't only show up on windshields.
Personally, I am not confident that the root issue here is the software itself. Altering the software by merely lowering the threshold in which loss-of isolation faults are determined to be safe, isnt really a viable option. The owners of earlier cars not setting this LOI DTC may actually be driving an electrically unsafe car! So while these people are currently all smiles and giggles, they might in fact be only oblivious to the inherant risk that exists.I remember when eBay had an outage and the world was ending -- the death knell for eBay. It managed to do OK. No doubt we'll see the same with the Leaf. While this is a HUGE PITA for the Leaf owners who have encountered the problem, overall it's not going to be a big deal. From reading the thread over at MyNissanLeaf it seems like it's a problem with the third iteration of the software. Not there in the first two, and it should be gone by the fourth.
Just like the Volt, the LEAF has a contactor that is opened to isolate the traction battery pack from the "under-the-hood" electronics when the vehicle is powered off to keep it safe when powered off.Probably the WORST thing owners can do is to merely "reset" these DTCs using a scan tool or Scanguage or by disconnecting the 12V battery. In fact while touching 12V battery negative they could very well be unknowingly putting themselves "live" to 300 volts positive (+) or negative (-) which on it's own isn't immediately dangerous, unless of course you find yourself simultaneously in direct proximity to the "opposite" pole.
No, I believe you misunderstood what I was saying and missed my point.Just like the Volt, the LEAF has a contactor that is opened to isolate the traction battery pack from the "under-the-hood" electronics when the vehicle is powered off to keep it safe when powered off.
The reason why clearing the DTC is the worst thing to do is that you affect Nissan's ability to properly troubleshoot and diagnose a problem.
To comment on the actual issue, I haven't had this problem in the 1,100 miles I've driven so far and I don't personally know any LEAF owners that have been affected. From the preliminary information gathered though, it appears to be a sensor set at too high of a sensitivity level. More information should be available in the next week or two.
