Another possible cause is inadvertantly leaving the car on with the headlights in automatic. When it gets dark the headlights come on and when the 12v gets low the ICE comes on to recharge the battery and eventually runs the gas down to the E and then the ICE no longer comes on and the 12v goes to 0 so you can't start it.
 
This has happended to us twice because my wife likes the headlight automatic mode but when she is in a hurry will forget to make sure the car is off when she gets out. It really kills your computed mileage too.

If indiananu's car was doing the same thing mine did today, it wasn't an issue with leaving it on. I've not left mine on and had actually used the car this morning and it didn't do the problem.
 
I wonder if they'll tell me an error code says it was ever low on gas, because I rarely if ever let it get below a 1/4 tank.

Well, dealer checked the hybrid system for error codes and there were none, but the problem is getting worse and more frequent. I'm kind of afraid I'll have to make the 3.5 hour drive to Jersey to get it fixed.
 
Other than not staying on EV when going down a hill without brakes (staying around 30 mph, so it's not that we are going over 42 or even close to 42 and the battery is full as well), the car is now not really charging the battery with the brakes. I can be exiting a highway with a downhill off ramp and the charge meter on the dash will barely get into the blue, like maybe half a centimeter. It is supposed to pretty much bury the needle at that point. Every once in a while it'll work correctly, but most of the time it's giving me a problem.
 
Gas mileage is WAY down as it also won't go into EV easily at all. If I'm coasting down from 45 or so, it usually won't go into EV until the lower 20's, even if I'm braking. Fairly full battery meter and the car is warm, it'll even do this after driving on the highway for 20 minutes.

is it really hot where you are? i find that the system doesn't charge as much if it's 90+ degrees out. i actually have better luck charging with the AC on

The first time a few weeks ago it was really hot, like close to 100, but it hasn't been hot every time it's done it. The past couple days were noticeably bad and it wasn't over 90, but upper 80's.
 
Air on or air off hasn't made a difference.

Engine shuttering normal or concern? by esages

I live in MN and purchased a used NAH with 1600 mi on engine from dealer in TX on line. Took for a short drive the day I received it & the red temp light came on. Took it in to local dealer and was told aparently coolant system had been flushed and refilled prior to purchase and system had a bubble. They topped off but light came back on a week later. They finally had to top off and vaccuum out remaining air and light has not come back on since. Told dual cooling system extremely difficult to burp.
 
Also since receiving car have noticed more than just a little jerk with initial motor start up after car has rested for more than an hour. It is more like a shutter, rattle, sometimes shakes steering wheel and shift handle. Very alarming and frankly embarrasing if anyone is around. It doesn't seem "normal", but have heard some rattle is ok? Could it be related to oil type as others have mentioned? Should I have this checked out? The car also seems to "twitch" or hesitate when I maintain 70mph. Is this just a quirk in the transmission?
 
So far have avgd between 35 and 38 mpg so guess I can't complain too much. Just second guessing myself for not buying "new", but couldn't beat the deal and car not available for purchase in Midwest.

Got the car back today after the dealer having it for two days. They said they spoke with the tech line and they stated the car switching between gas and EV every two seconds coasting down a hill is normal. BS. I've had the car over a year and it's never done this until now.
 
Also he stated he drove and drove the car and everything seemed normal although he doesn't have any other hybrids to go by as a comparison. I guess drove and drove means the ONE mile they put on the odometer. Normally I like that they don't put any miles on the car, but not in this case. Also, don't tell me that you spent a lot of time driving the car if it's obvious you didn't.
 
Does anybody have a number for a technical line to Nissan? I know what they call is probably a dealer only line, but is there a number for a consumer to call?

help? no EV mode at all! by jsyaruss

Greetings all -- Got my NAV about 2 1/2 weeks ago...worked great until 2 days ago. Then, it started the "shudder." Plus some revving up and down on occasion. Ugh.
 
Was reluctant to take it to a local dealer because of the lack of hybrid experience in my area. Found a hybrid certified technician who said that the problem was that the engine was set to rev to high (1200 vs. 1000 rpm). Said he recalibrated it and all was well.
 
EXCEPT for the fact that even though the gas engine runs smoothly, I can't get it to go into EV mode at all! Even just when I turn it on, it sits in EV for about 10 seconds then the gas engine turns on and stays on. The dealer didn't have a clue (the hybrid certified tech had already gone home). Said it was because the battery wasn't fully charged, but it never is. It's typically just about 1/2-way and fluctuates a little up and a little down from there. I drove it a bit to ensure a full charge but still no EV.
 
Anybody else had this? More than a little discouraging. The dealer where I bought it is 4 1/2 hours away. By coincidence, I'll be there next week anyway but I would hope this is an easy fix.
 
I hate doubting a purchase like this - i've been very happy with it otherwise. Help?

How long are you driving it after starting it up? I've found that once you turn the car off it doesn't switch into EV easily for a while the next time you drive it even if it never had time to cool down.
 
I doubt that is your issue though, but just a thought.
 
Just curious, what state are you in? I am also not in a NAH state and I'm running into dealer problems.

Unfortunately, I get the same situation whether I drive short distances or long. Right now, it seems to be operating as a regular old 4-cyl car with an electronic motor booster... everything seems fine except no EV. Another appt with the dealer on Monday, so with luck, they'll figure it out.
 
i'm in PA -- near pittsburgh. There is a hybrid certified tech about 30 mins from me, but sadly, mine is the first hybrid he's worked on...
