If you can reproduce the problem, all the better.

Take it back and have their certified tech come or a test drive with you (let him drive).

The Air Conditioning compressor is (I believe) battery powered on this vehicle, as opposed to being belt driving off a conventional gasoline engine, so it will place a higher draw on the electrical system overall.

Beyond that, I can't offer any advise, just waiting for mine to misbehave so I can go back and yell at the dealer again. After you get the car back the next time, you should call Nissan and log an incident, indicating that you have this problem that the dealer is somehow unable to diagnose and fix.

If enough of us call, they'll take the matter seriously and open up an incident to have engineering get involved. As I suspected before, there is a firmware bug someplace that either misbehaves when a sensor reads incorrectly, or a part that is failing within the electrical system and giving data that the computer cannot act upon in any civilized manner.

In such a case, a check engine light should illuminate and service codes logged so that when the dealer plugs in their computer, they can act upon it instead of coming up empty.

I'm a firmware programmer by trade and have been working in this field for 22 years. Believe me, something is amiss. Getting to it is the challenge. I predict a service bulletin but not for a while. The "computer gets confused" is not a good answer, it all comes down to error code logging and trap handling.

Problem is, there is no one place to list consumer cases like this (there are likely dozens of forums of disjointed and disenchanted owners). The splintered approach will never work and the dealers will not necessarily feedback concern to Nissan.

In addition, Corporate may not review the cases on a proactive basis and possibly does not have a procedure to monitor these types of incidents so do us all a favor and call Nissan and explain the situation in as accurate and clear terms as you can.

Not sure if Nissan is selling the hybrid next year based on Toyota technology or when their contract expires but if we do not get a solution, we are going to be in for years of pain.
